• iMac does not start after the update of the Sierra...

  Don't know what to do. Sierra, just updated and now my system hangs during startup and turns off.

  Anyone else seen this? No idea what I can do?

  Try a safe boot. Otherwise, you might to reinstall macOS.

  ----------

  Stop your Mac. Use the power button if you wish. Now start with the SHIFT key is pressed. This will start in Safe Mode, with all extensions turned off. Safe mode is slow to start, so give it time, it checks a lot of tasks. If it works fine in Safe Mode, restart normally. If it works now, you are finished.

  If the problem comes back after a reboot, you may have an extension conflict. Disable all extensions via system preferences. To isolate which extension is at fault, turn on an extension at the same time, restart in the meantime, until you find bad.

• ITunes does not start after the installation of Windows 10

  ITunes does not start after the installation of Windows 10, 1511 version (OS Build 10586.164). ITunes version 12.3.2.35, 6 GB RAM, Intel i3 @3.3 GHz. Itunes and Ipodserver module will run by Manager jobs, but Itunes does not open. iTunes starts in SafeMode as explained in the link below (hold SHIFT and control on your keyboard while you open iTunes).

  Fix unexpectedly closes or problems of launch in iTunes for Windows - Apple Support

  Solution, according to this link, is:

  If the problem does not occur in Mode safe, remove any third party plug-ins iTunes: solving problems with third party plug-ins - Support Apple iTunes but the link has been archived, and I can't find any plug-ins installed iTunes. Any other ideas?

  For general advice, see troubleshooting problems with iTunes for Windows updates.

  The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

  Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

  More information area has direct links with the current and recent buildings if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit-for old video cards) as a workaround for problems with installation or operation, or compatibility with QuickTime software or a third party.

  Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

• Computer does not start after the screen of the bios, Compaq Presario SR1023WM

  Ok. Trying to fix a friend's computer and seem to have met a strange barrier.

  Problem: The computer does not start after the bios screen.

  Details: When you turn on the computer, the compaq logo with intel inside is and has the < F1 Setup > and < F10 System Recovery > options listed as well.  And that's it as far as the computer becomes.  After that the computer just locked up, no work of buttons on the keyboard lights keyboard ect ect.  I tried the puree on the F1 key, as soon as I turn on the computer and I can handle so he can say * entering setup * but it freezes again after this point.  I already tried to eliminate the possible sources of the problem, removed all expansion cards, HDD and Dvd Rom module only disconnected, only memory (256 MB ddr 2700), power, vga and keyboard connected.  Ive also used the jumper on the motherboard to clear the cmos, hoping that would solve the problem without success.  I tried using a different memory stick and different memory as well...  Tried to use both a ps2 and a usb keyboard... Ive even tried pulling the rider for the protection of the bios password (even if she did not have a password on it, just try everything I can think of).

  The installed bios version is 3.1, and that's all that I know on the computer at this point, except that the website tells me to him.

  http://h10025.www1.HP.com/ewfrf/wc/product?product=411354 & LC = on & CC = US & DLC = in & Submit.y = 5 & Submit.x = 3 & lang = to & CC = US <-link to the Web page for the model #.

  I'm basically at a loss on this one, so if someone feels scroll line-by-line of their brains on this one, I'd be very happy.

  I have a pretty strong understanding of computer repair, so feel free to give me something to try.

  If you need more information out of me, let me know as well.

  Try to clear the CMOS again but this time remove CMOS battery and hold the power button on a few seconds. Replace the battery, then try to start back to the top.

  At the back of the pc is the condition of the PSU led green or flashing?

• Re: Smoker L30-10 X PSL33E does not start after upgrading RAM

  Hello

  I have a problem with my laptop.
  It has 1024 MB of RAM (2 x 512), but it wasn't enough, so I decided to update to 2048 MB (2 x 1024).

  I bought two modules and my computer does not start after changing them.
  It was only a screen black (same BIOS has not started). I tried another combination of installation of memory modules RAM.
  2 x 1024 - did not work
  1 x 1024 - did not work
  1 x 1024 + 1 x 512 - working but not properly.

  BIOS find that I only 896 MB (1024-128 for the video card)
  I said OK. Let's see what will show windows. He was also 896 MB.
  I launched CPU - Z and it shows that the total size of memory is 1536 MB (medium detect both modules).
  I found that CPU - Z detect 1 module 1 024 MB and 512 MB secondary, but the BIOS detect only 1024 MB 1536. How is that possible?

  I have fought, is that my BIOS is old, then I update the toshiba Web site form most recent version, but the problem persists.
  Please someboy help me and tell what to do.

  PS. the Modules are new and work correctly.
  They have been tested.

  Hello

  Have you used two identical RAM modules?

  What kind of modules did you use?

  In my view, that the problem is related to the new, inserted modules.
  There must be something wrong with the modules or modules are not completely compatible if the laptop can not boot after installation.

  According to a few pages of the book handles the DDR2 533 MHz (PC2-4200) 200-PIN SODIMM modules.

  Did you use these modules?

• Satellite A200 PSAEOE does not start after upgrading memory

  Hi, I am first time here.

  I bought a Toshiba A200 PSAE0E-03J02JDR with 2 GB of RAM. I bought a pair of ram Corsair (2 * 2 GB VS2GSDS667D2). The computer does not start after that I installed the memory. I have intel 945 chipset, which is capable of 4 GB (manual page 1-2). The bios version is 1.8 2007.

  Can anyone help me, please.

  Post edited by: Marian ovidiu

  Hello

  The A200 series supports different chipsets;
  Intel 945 PM
  Intel 945GM
  Intel 943GML

  As far as I know your laptop supports the * 943GML * Intel chipset and the chipset supports 2 GB RAM max.
  Take a look at your laptop s user manual * Page 18.*

  Summer: 4 GB of RAM are not possible, and therefore your laptop does not start.

• Satellite P200D-130 does not start after upgrading RAM

  Hi, I just upgraded the RAM on my P200D 130 but it does not start after that.
  I removed the 2 Hynix 1 GB PC2-5200 and put in 2 SO Kingston DDR2 2 GB PC667 (should be the same as PC2-5200).
  Post-market nothing happens, light power control is turned on, I him stays CD drive but screen black, no beeps.

  I put one of the 1 GB modules, it starts normally, then I tried a 1 GB into the lower slot module and a 2 GB module in the top slot and it works.
  I tried a single 2 GB module in each slot, even in the form of 2 2 GB modules.

  What could be the reason, better: what would be the solution to ensure that the modules of 2 x 2 GB to work?

  Thanks in advance,

  Michael

  Hello!

  I think that both modules are not compatible to the laptop.
  Normally you can upgrade your laptop to 4 GB. Look in the user manual.

  The RAM, you should bring the computer dealer and request a new one. More buy modules with the same specifications and dimensions. Try buying RAM with the same specs as before.

  Good bye

• Pavilion HPE H8-1121: Pavilion HPE H8-1121 - new graphics card + power supply does not start after screen HP (Revisited)

  I have the same problem as this post 2013!  Ouch. Pavilion HPE H8-1121 - new map chart + power supply, does not start after HP screen.

  I installed a new power supply (Seasonic 620W), which works well.  I also installed a GTX 660Ti last year and it was works fine as well.  I recently bought a ZOTAC GTX 970 and attempted to install it, but it will not go beyond the blue HP screen and I get the same code of beeps (1 long, 3 short), who, seems, suggests that the video is not initialized.

  My BIOS date is 2011.

  Where can I find an update for this?

  I'm also using Windows 10, which I found on the HP site is not tested on my model and would probably not favourable to good use.  Should I do back up to 7 or 8?  and then update the BIOS?  Y at - it a update for my BIOS and where can I find.

  In any case, I hope that this is a solution.  Again, this is not a bad machine to be 5 years old.

  Thanks for any help!

  If the video card that you have purchased dose not a legacy vBIOS it will never start. An update of the BIOS doesn't solve that.

  It is likely that your new video card has a vBIOS UEFI and that only is for the PC motherboards newer than yours which have a UEFI BIOS. Your motherboard has a legacy BIOS. 2012 is the year of model when the UEFI BIOS more or less became the de facto on motherboards standard.

  I return it for a refund. Find the candidate of video cards that support the old BIOS. It can be inherited only or switchable vBIOS (legacy or UEFI) vBIOS.  I suggest looking at the site of Sapphire Technology. ZoTac is not known to provide enough information about their video cards in the way. You upgrade a pre-built desktop PC and it's different and a little more difficult to set up a DIY PC. I looked at the site of Zotac and see that nothing is said about their video vBIOS cards.  I would return to the map.  Carefully read the specifications of the video card. A candidate for your motherboard card must have inherited vBIOS support or simply, it won't work.

  ZOTAC (they don't say anything about their product vBIOS)

  Sapphire Technology

  http://www.sapphiretech.com/catapage_pd.asp?cataid=305&lang=eng

  Because you look at game with 4 GB cards. Take a look at the following map. It has a double vBIOS. legacy and UEFI. http://www.sapphiretech.com/productdetial.asp?pid=640A98CD-0CF0-4191-B75C-CA2800111ADB&lang=eng
