  Hi Chris,

  1. What is the Biostar mother board model number?

  2. What are the specifications of onboard graphics card?

  3. have you updated the BIOS and drivers from the chipset?

  Check if the Biostar mother board model is compatible with Windows 8 by clicking on the link.

  Since you mentioned the problem on different versions of Windows 8. Either the card mother or graphics card is perhaps not compatible with Windows 8, or you must update the BIOS and drivers from the chipset. Contact the motherboard manufacturer support to improve the assistance on the update of the BIOS.

  Warning of the BIOS:

  BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  If the problem persists, you will need to update your graphics card. For more information, see supported by motherboard Biostar.

• Ink Deskjet F4580 HP60 horizontal lines, tried all possible solutions

  I have a HP Deskjet F4580 (old, I know) who has been sitting in my closet for about a year. I just bought a total amount of new ink for it (and probably paid more ink than the printer's worth), but while the black ink works fine, color ink does not work, send me white lines through the bands of color on every possible test or diagnostic page that I could possibly print. I cleaned the cartridges, clean the contacts, reset the printer, run the Print nozzle cleaning and run alignments. I'm on the tipping point of dreaming all violent means that I could possibly throw this printer in a way that would make the $75 I spent on ink is worth it. ALL suggestions are welcome, but I have all my scowering prowess tech past the internet for clues, so please do not suggest a forum search. What baffles me the most, is that since several cartridges do not work, I guess that the problem to be with the printer itself, but the black cartridge works fine.

  Thank you all,.

  Ryan

  I would say that the troubleshooting steps described in the paper here.  When you print a diagnostic page as on the solution six are there lines across the three colors in the same place?  If yes the problem is almost certainly an electrical contact between the printer and cartridge or a failure.  To remedy this, I suggest to clean the contacts of the cartridge and printer as shown in the document here.  (It is a different model, but the procedure is the same.)

  If this does not resolve the issue please scan and post you printed the diagnosis page.  Black information serial number in line 11. privacy.

• Strange horizontal lines on the 2nd monitor (TecS1 + ATI) multiscreen mode

  Hello

  I have a kind of a strange question when I'm working in mode multi-display with a Compaq 9500 19 "monitor as a second monitor attached. When resizing of content, a large number of strange horizontal lines, some short, some long, (in fact quite random) appear spread out on the full screen.

  It seems that the graphics card ATI Mobility Radeon graphics buffer is corrupted somehow, I can still work, but it's still annoying. I have to say that this problem seems to appear only on Windows Server 2003, not when I run the Tecra S1 under XP (installed as multiboot). So, it might be a driver ATI - OS incompatibility.

  Any help would be much appreciated.

  Thank you
  Mark

  Hi Mark

  In my opinion, you are absolutely right. It's probably the driver ATI - OS incompatibility. All drivers are adapted to work properly with the operating system supplied with the notebook. Windows Server 2003 is not supported by Toshiba and I think it will be the problem to solve this problem.

• ThinkPoint infected computer won't allow any mode of windows to start: safe mode, normal mode, etc. A black screen is all I get.

  I have two computers. Those infected with Windowx XP Home Edition. All of a sudden (yesterday October 18, 2010) the ThinkPoint popup appeared. On my own computer, I looked for solutions and has been able to stop the service through the Task Manager. Then downloaded MalwareBytes. He scanned and detected 5 elements. He then opened a text window indicating that the 1 point might be deleted and needed to restart the computer. So, I followed the instructions on the window of MalwareBytes. But after reboot, a black screen. If he walks again and a black screen. F8 works but after I chooseany mode (safe mode, previous configuration, etc.) a black screen again. I looked for solutions and all assume them safe mode or any different normal windows mode, it works. My problem is that no boot option (same normal Windows) seems to work.

• Windows Vista does not load, can not use Safe Mode, etc.

  Computer/laptop: Dell Inspiron 1525
  Running: Windows Vista

  I hope someone here can understand this, but it's a pretty serious problem for me for two days now.

  Two days ago I started my laptop that I normally have.  I did insofar as the office, and then once I tried to move my cursor autour, nothing happened.  Instead of using the cursor, navigation with the keyboard, I tried once more, nothing helps.  Everything was just frozen.  I didn't think much at the time, because I thought maybe it was just one of those random freezes, restart the computer fixed.

  But my problem got worse.

  After the next reboot, my computer is doing as much as the black screen with the Green loading bar with the words "Microsoft Corporation" under it... and where he remained for more than 6 hours.  It's exactly what it does whenever I restart the computer.  Just in the limbo of the permanent load.

  I held F12 on boot to the top and ran a diagnostic test, which revealed nothing wrong.  I tried all the options under F8, including all variations of Safe Mode, and once more, nothing has worked.  Even more frustrating is that the computer could not even finished loading command prompt when I tried "Safe Mode with command prompt."

  The only clue I've gotten so far was a blue screen randomly with a single line of text that read something like: "'STOP: c00000033 object name invalid ." "

  Essentially to: nothing works, and I not made any changes to the computer itself, between the time he was working, and now when it is not.  It loads just for as long as I leave the computer running.

  Help or light on this subject would be much appreciated, as the thought of losing everything on a computer, I've had for almost two years is quite upsetting.

  Hey Maverick 104,

  Step 1: Disconnect all external devices (printers, scanner, USB (universal serial bus) readers, etc...)  Except the keyboard and mouse and then start.

  If this solves the problem, then add back devices at a time until you discover the piece of hardware causing the issue.  Then get any drivers\software update for the device.

  Step 2: Try (method 1) system restore and repair the startup (method 2) as indicated in the link below:

  Your computer may freeze or it may restart to a black screen that has an 0xc0000034 error message after you install a service pack for Windows Vista

  http://support.Microsoft.com/kb/975484

  Step 3: Start the computer to system recovery options (follow the steps mentioned in the link below) > select command prompt tool and run Check disk to repair bad sectors on the hard disk.

  http://Windows.Microsoft.com/en-us/Windows-Vista/what-are-the-system-recovery-options-in-Windows-Vista

   

  At the command prompt, type chkdsk /f and then press ENTER.

  Now, type chkdsk /r , and then press ENTER.

  Note: CHKDSK would attempt to recover bad sectors on the hard disk, in the course of this process there are chances of DATA loss from that particular area.

  Let us know if it works

• Windows 7 Pro black screen with cursor on all modes and no login screen

  OK so basically, it's how, my laptop decided to me-screw right when I need to make some adjustments to my final project for next week.

  Friday he started very well in class and at the end of the course at 6:30, I stopped him. I normally don't that often stopped because I usually find myself opening upward in an hour later. But I did this time and when I got home and turned on around 9:00, it started like this:

  Screen Compaq PhoenixBIOS > Windows boot animation > black screen with cursor mobile, no login screen

  No screen connection. No sound. Not nothing but a black screen and the cursor movement. So I force shutdown and turned it back, this time he asked a chkdsk and I ran it. A ton of stuff file unreadable came and it took all night to run through it all. Tried to start again and Windows Error Recovery came and I tried all Modes of security and start normally and all produce the same black screen and the cursor with no login screen.

  Then I used my Windows 7 dvd repair to try and system restore to a week before. That's where I noticed that windows had installed a critical update at 12:00 on Friday. Tried to restore before that, but he failed. Gave me an error 0 x 80070057 and said I should run chkdsk /r and then try again. Then I used the cmd prompt through dvd repair and he has seen all these things wrong file again once recovered things then realized hours later. Tried to restore the system again. Still the same error. A run chkdsk again through the cmd prompt, then he went to clean without errors or orphaned files or anything, but it took a lot of time. I used the Startup Repair, and he has not found anything wrong either. But still the same error the system restore.

  So I looked around online for the last two days, trying to figure out and that someone said to try CTRL + Alt + Delete, the sticky shift key thing. So I tried to boot the system again, same black screen with cursor movement. I did CTRL + Alt + Delete, nothing. Press and hold the SHIFT key, and a pop-up window asked FilterKeys. Press the SHIFT key 5 times, a popup asked about sticky keys. But that's all I can get it to do. Nothing else. I tried to boot into safe mode with F8, chose, each of them and that changes in screen resolution and the words "safe mode" in all the corners of the screen. If the repair dvd's while I start in safe mode, it will open as well in safe mode, but with the same black background mode. Tried running sfc/scannow through repair invites cmd of the dvd and it says a system repair is pending and he had to restart, and then run the sfc/scannow. Tried, but it doesn't do anything when I restart except go to Windows Error Recovery asking either start in any safe mode or normally. And then it's just black screen again.

  So I am at a complete loss what to do now. After all of this mess, it seems that this Windows Update Friday afternoon did something and when I booted it upward once again, his cause nothing but problems. I think it has something to do with the display and the graphics card drivers? It's as if the thing starts but I do not see anything either because the sticky keys appears, but sees nothing else, no matter what I do. Seriously, I don't want to this junk because this is a new hard drive and I was just able to retrieve my files from my old hard drive that had epic failures as well. And I just got this new specifications I wanted as well.

  Laptop Spec:

  Compaq CQ50-115nr
  OS: Windows 7 Professional
  HARD drive: Western Digital Scorpio Blue 320 GB SATA WD3200BEVT
  Processor: AMD Turion X 2 RM-70
  Graphics card: NVIDIA GeForce 8200 M G
  Memory: 3 GB RAM

  If someone could seriously help me I would be VERY happy.

  Hello

  This isn't good news.

  STOP: 0XC000021A

  Can be a difficult problem to solve, and you indeed need a technical help in a real store of the computer
  (not the leeks and the glances at a BestBuy or other BigBox stores) or system manufacturer support.

  Cause

  This error occurs when a subsystem of mode user, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), irremediably compromised and security can not be guaranteed. In response, the operating system goes into kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, it is one of the rare cases where the failure of a user mode service can stop the system.

  Incompatible system files can also cause this error. This can happen if you restored your hard disk from a backup. Some backup programs may skip restoring system files which they determine are in use.

  Solve the problem

  Run the kernel debugger is not useful in this situation because the error occurred in a user mode process.

  Resolve an error in the user-mode device driver or system, third-party application service: Because the bug 0xC000021A control occurs in a user mode process, the most common culprits are third-party applications. If the error occurred after the installation of the new or updated device driver or service system, third-party applications, the new software should be removed or disabled. Contact the manufacturer of the software on a possible update.

  If the error occurs during the system startup, restart your computer, and then press F8 to character-based menu that displays the choice of operating system. In the Windows Advanced Options menu that results, select the last known good Configuration option. This option is most effective when a pilot or a service is added at a time. If the error is not resolved, try to manually remove the offending software. If the system partition is formatted with the (FAT) file allocation table, use a MS-DOS boot disk to access the hard disk of the computer. If the system partition is formatted with the NTFS file system, you may be able to use Safe Mode to rename or remove the defective software. If the defective software is used as part of the start-up procedure of the system Safe Mode, you must start the computer by using the Recovery Console to access the file. If a room newly installed if material is suspected, remove it to see if that fixes the problem.

  Try running the emergency recovery disk (ERD) and allow the system to repair any errors that it detects.

  Solve a problem of file system do not match: If you have recently restored your hard disk from a backup, check if there is an updated version of the backup/restore program available from the manufacturer. Make sure that the latest Windows Service Pack is installed.

  It's my generic bluescreen convenience store - you can try Mode safe mode as suggested in article
  above - repeatedly press F8 that you start. Disks of Vista are probably necessary - if you do not try to repair it, you can borrow a friends because they are not protected against copying. You can also buy the physical disks
  good system machine cheap that you already own Windows (you have to reinstall them if)
  required). You can also repair disks on another computer.

  Here are a few ways to possibly fix the blue screen issue. If you could give the blue screen
  info that would help. Such as ITC and 4 others entered at the bottom left. And all others
  error information such as codes of STOP and info like IRQL_NOT_LESS_OR_EQUAL or PAGE_FAULT_IN_NONPAGED_AREA and similar messages.

  As examples:

  BCCode: 116
  BCP1: 87BC9510
  BCP2: 8C013D80
  BCP3: 00000000
  BCP4: 00000002

  or in this format:

  Stop: 0 x 00000000 (oxoooooooo oxoooooooo oxoooooooo oxooooooooo)
  Tcpip.sys - address blocking 0 x 0 00000000 000000000 DateStamp 0 x 000000000

  It is an excellent tool for displaying the blue screen error information

• Photosmart C5180 HORIZONTAL lines appearing suddenly on all scans

  I get horizontal lines randomly on all my scans all of a sudden when I use my Photosmart C5180 all-in-one.  Scanned a few things this afternoon and everything was normal.  Then, suddenly, a scan I did had much random horizontal lines (perpendicular to the direction of motion of the trolley) appearing thereon.  When the scan is in color, the lines are of different colors.  On b/w scans, the lines are black.  They appear in different places if I rescan and are random.  They are between 1/4 "and 1" long.  Any ideas?

  Please do not send all of the links for troubleshooting vertical lines, as is not the same problem.  In addition, it is scanning only... printing functions remain normal, please so no printer/ink articles either.  Is longer under warranty so it doesn't get service unless I pay extra, and I don't want to lose money if I just need a new machine.

  Any help is greatly appreciated, even though I'm starting to think that the solution is to buy a new all-in-one.

  I don't think you can buy a HP spare bulb, but you might find them on sale on 3rd party websites (but reliability then comes into question). If you were able to get a spare bulb, so you will need to find someone qualified/tech-savvy enough to replace it.

  I think that ultimately, you could end up spending more to look for party and someone to install it as you would on an all-in-one replacement. You could buy a separate however scanner and continue to use the C5180 for printing.

• Inspiron 14 3420 - crashes and random horizontal lines poster model

  I bought the Laptop Inspiron 14 3420 in December 2012. I am facing some problems of display on this laptop, it hangs and displays patterns of horizontal lines (like: http://www.youtube.com/watch?v=zOjTK4ic1E8) and it happens randomly and not always.
  It happened a few months before and then automatically slipped, I thought that this could have happened due some application installation. But now its past very frequently, I don't know what is the cause.
  I tried to change and update drivers display for both integrated Intel card graphics and Nvidia graphics card, but the problem is still there.
  I tried Googling this problem and found that this could be the problem of Nvidia graphics card, so I have disabled this card from the Device Manager, but it does not solve the problem.

  Hi mominbilal,

  Try to release the residual charge of the system. Here are the steps:

  • Disconnect all external devices (printers, external hard drives, flash drives) on the computer, including the battery and the AC adapter / CC.
  • Press and hold the power button for 20 seconds.
  • Reconnect the battery and the AC adapter / CC. Try to restart the computer and check.

  In addition, run 'Diagnostics' on the system to confirm the operation of the equipment. Here are the steps:

  • Restart the system and immediately start typing on the "F12" key to enter the "Boot Menu".
  • Press the "Down arrow" to select the option 'Diagnostics '. Press the enter"" key.
  • The diagnostics begin. Please note the exact error message / code, if everything appears on the screen.
  • You can also view the video on the link http://dell.to/17DCL0R for more information.

  Check also if there is no problem with the LCD display by running LCD BIST (Built in self test). To run the LCD BIST, press in and hold the D key on the keyboard while pressing the power button, then release both buttons at the same time. This will launch a screen gray, then red, then blue, then green then white, to allow you to inspect the entire LCD to the purity of the color on each screen and to better identify defects such as cracks on the LCD screen or stuck pixels which is perhaps not obvious in normal display mode.

  Try to connect the system to an external monitor when the issue appears to happen again if the issue reappeared on screen external source or not. This will help us to further isolate the issue.

  Please answer with the information, I'll be happy to help you further.

• Satellite Pro 6000 - horizontal line on top

  I have a problem with my toshiba Pro 6000 1.2 Ghz, since I installed the new bios or new drivers windows Toshiba video.

  In fact only 6000 has a screen of 15-inch (and not the 14-inch), and when I start it up I see everything, but with a horizontal line at the top of the screen (which change color, can be white with text mode, being black or blue under windows, etc.). The text screen is pressed by about 2 cm from the edge in text mode (during booting, for example.) Red logo Toshiba at the beginning).

  It seems that the Bios (or pilots, but I do not think because that's also how during startup) does not correctly handle screen 15 inch laptop computer. I installed the version 1.60 of the Bios. I don't remember the version I was using before.

  If I install a 14 inch screen, I don't have the line and I don't have the text squeezed by 2 cm from the top screen.

  According to me, but I'm not sure that the problem is not hardware, but more by a software problem (I hope).

  Thank you in advance.

• HP EliteBook 8440p: white horizontal lines on the screen who retreat down in the minute

  Hi again. I've already posted about this so there are pictures and a full description of my post a few days ago. In short, when the laptop was arrested or sleep for more than a few hours, it is white horizontal lines on the lower part of the screen that slowly fade completely down. The lines do not appear on an external monitor in dual mode.

  I removed the screen twice now and checked / reinstall connections to the screen and under the keyboard. The problem persists.  I flashed the BIOS a few days ago and the problem persists. The webcam, microphone and WWAN/WLAN are all in perfect condition and the computer works fine apart from this problem of screen work.

  Until I drop the most money on this used laptop that is my only question at this point sounds as strictly a matter of cable/display on the screen? If it's a motherboard problem I would see other problems? If it is the graphics card goes wrong I would see other problems? As I said, the computer works perfectly once it is running.

  Anyone has any useful ideas?

  Hello

  You can try to connect this unit to an external monitor to check if there is a problem with the motherboard or display

  If the external monitor works fine, then there is no problem with the motherboard, only the display panel needs replacement.

  If the problem persists in the external monitor, suggest you to update the graphics drivers and see if the problem resolves

  I hope this helps
