  • Can I place a Dell OptiPlex 755 with Intel Core 2 Duo in Windows 8 Pro to Windows Pro 8.1?

    Can I place a Dell OptiPlex 755 with Intel Core 2 Duo in Windows 8 Pro to Windows Pro 8.1? I tried several times. I wonder if my computer does not meet the requirements for upgrade. How can I?

    Hello Andrew,.

    Thanks for posting your query on the Microsoft community Forums.

    According to the description, you want to upgrade to windows 8 for windows 8.1 on your system.

    As you already use windows 8 on your system, you can try to upgrade to windows 8.1. However, there are some system requirements that are needed to run windows 8.1 correctly on your system. Please see the link below for the topic of system requirements.

    Reference:

    The system configuration required

    Outside the system requirements, you will also need the windows 8.1-compatible drivers. There is a possibility that some devices may not work if the compatible drivers for windows 8.1 are not installed on your system. Driver are manufactured by the manufacturer of the system. It seems that Dell has not made drivers for windows 8.1.

    Refer to the link checking the available drivers for your system.

  • Problem with the Dell Optiplex 755.

    Have a refurbished Dell Optiplex 755 with windows 7, only a few months ago.  Sometimes the screen rises all yellow and you can't get out.  Sometimes screen goes all black but if you click anywhere on the screen with the mouse will go up all that is behind the screen where you clicked, but you must do it all over the screen to see what is there.  Now the last week or so whenever you leave the computer and return windows has recovered from an unexpected shutdown down.  Can someone tell me what could happen?

    This behavior indicates a video problem.

    A cable loose or damaged video from your computer to the screen.

    A failed video monitor.

    This computer has a separate video card?  If the cable connected to the back of the PC is vertical, the answer is probably no.  If it's a separate video card, you need to open the PC and remove, then reinsert the video card - its called re-seats of the Board of Directors.

    How old is follow you and what type is - LED or CRT.  Is - this really really heavy?

    Remove and check the end of the thread and examine the tiny pins in the connector, none of them are bent?

    The judgment is not likely related to changing the color on your screen.  A number of things that cause, but you need to check your hard drive and check the temperature inside the box.

    Turn off the power.  Hold the button for 7 seconds.  Open the case and see if there is a lot of dust.  Have one of those cans of compressed air.  Blow off the dust from the case.  Pay special attention to the fan on the processor with the fins of the radiator aluminum under him.  Make sure that it is free as well as fans of dust.

    You should test the hard drive to ensure that it is not a failure.  If you tell us the manufacturer of the drive, we can tell you where to find the appropriate software.  In the text box above the globe on the left lower part of peripheral type.  Type of device.  Click on Device Manager.  In the window that appears, click the small arrow to the left of the disc.  Send us the model number, you can see it.

  • Dell Optiplex 755 SFF 2015 video card update

    Dear readers.

    I'll buy my first Dell computer, which is a Dell Optiplex 755 Small Form Factor. It has a Core 2 Quad q6600 CPU in it, with 2 GB of ram and a PSU 275w. I have a Nvidia Geforce GT220 video card, which is a low profile video card, it can consume the maximum of 58 W, and this video card requires at least 300 W works without problems. Will it work with this diet?

    Link to the video card:

    Thank you!

    whadez
    I'll buy an Ati Radeon HD 2400 XT, because im does not intend to do some games 'hardcore' and other animals, it can be good for my needs.

    The 2400XT is very outdated and terribly weak power. You are much better with people like a Sapphire 6450, that can be done for $43 postpaid from Newegg.

  • Video card in Dell Optiplex 755 Desktop HELP

    Hello everyone, I'm new here and I really need your help :)

    I have a Dell Optiplex 755 desktop computer and incredible as it may seem that I did not know the Office had no graphic card (video card?) lol x)

    The Office gave at Christmas, I wonder if you could indicate a video card ideal for my desktop PC which is not too expensive.

    I use Windows 7 Pro, I don't know much about computers components, but I found this graphics card what you think? Will work or not? graphics-cards.specout.com/.../ASUS-GeForce-210-Silent

    I really need your help guys.

    This is bad advice because the card in question is not necessarily in all cases EXCEPT TOUR because of the unique slot configuration.  FAT OFF heat sinks will not physically go in the models of desktop SFF and USFF has no slot so no card is an option.

    Radiator to map out more 1 wide slot.

    This is why I always recommend specific ASUS Radeon HD5450 or 6450 cards.

  • Dell Optiplex 755 SFF - How: maximum performance?

    Reference Dell dear users.

    I have a Dell Optiplex 755 SFF, and I would change all my materials for the best components that I can use.

    Is it possible to upgrade my processor Q6600 to a Q9550 / Q9650?

    I know there is no Q9550/Q9650 on the compatibility list, but I saw someone put the CPU into this motherboard, and he said that he works very well with this motherboard. So, what is your suggestion? I would like to give it a try? Will it work? Or is it just a complete?

    Is it possible to put a primary HARD drive and a secondary SSD in the system?

    If this is the case, what is your suggestions? I thought about a 120 GB SSD system and a 1 TB Western Digital HARD drive, it's a good combination? (7200 RPM, SATA)

    Who is the STRONGEST Videocard for its price, which can adapt to this mobo?

    Many people say LP 7750 HD is the best of what you can get, but I checked ebay and other Web sites, even sought a 7750 HD LP "pre-owned", but I could not find. What video card do you offer me?

    ((Current))

    Q6600

    RAM 2 GB (1x2Go)

    INTEL GMA3100 (: C)

    150 GB HARD DRIVE

    PSU 275W

    Thank you!

    7750 (now called profile low 250 R7) uses more than 25W you run the risk of damaging your system.

    Low Profile Fanless Silent ASUS EAH6450 to 27W is the max I would use.

    SATA, who worked at the 2 update driver update changed 3.  So, you may be able to work around the problem of disk with a modified file, you can probably find at vm-help, but you will still need a NIC for networking.

    Error loading \3\DLBUtime.dll

    I have a Dell computer that came with Windows XP Home edition.  When I start my computer the monitoring of ERROR appears: RUNDLL error loading specified not found \3\DLBUtime.dll module

    I just click 'ok' and he goes, but, as for what it stop popping up everytime I start my computer.

    Can someone help me with this?

    Aprilm,

    You are LuLu5119, who posted a question last August?

    If this isn't the case, you should have started your own thread.  If so (and even if not), you should have responded to questions about Dell printers.

    Assuming that you complain of a "Error loading \3\DLBUtime.dll" message that appears when you start your computer, you should know that the DLBUtime.dll file probably has something to do with the software from Dell which has been partially deleted, but could also be indicative of malware as well as partially withdrawn.

    In both cases, the best way for start you to prevent the message at windows is to download Autoruns http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx

    Install the Autoruns and let it complete the scan of your computer.  Then click on the "Connection" tab and uncheck the following entry:

    Look for an entry that has 'DLBUCATS' in the first column.  If you do not see that, look for "rundll32 \3\dlbutime.dll" in the last column ("path of the Image).

    Uncheck that entry, close Autoruns and restart your computer.  You should get is no longer the message.

    If for any reason, you find later that you need dlbutime.dll running, run Autoruns and check the box. If you decide that you need never again, run Autoruns, right-click on the entry and select Delete.

    As General precautionary measure, in case your entry dlbutime.dll was related to malicious software, rather than the Dell printing software, download the following free scanners:

    MalwareBytes Anti-Malware: http://malwarebytes.org/
    SUPERAntiSpyware Portable: http://superantispyware.com/portablescanner.html

    For MalwareBytes Anti-Malware, download, install, update and run.
    For Portable SAS, follow the instructions on the Web page (note that the instructions assume that you use a different computer to download; if you're not, just make a note of the name of the file).

    Hi all! :))
    I have an optiplex 755 minitour. I have a gt graphics card EN8600, I want to buy http://www.asus.com/Graphics_Cards/R72501GD5/ it. It comes in the box? I know that low profile 7750 is the best choice, but in my country is not available. Sorry for my English when I wrote something wrong. Thank you for your answer :)

    OK, so I ended up buying the card low profile Diamond HD Radeon 1 GB for my Dell Optiplex 755 minitour, well right off the bat I knew there would be problems, firstly the big black box is really tight against the card and because of two "transistors" just above the video card slot radeon hd7750 didn't come home. So I removed the top of the video card fan and he went, but when I got to the top of the computer screen, black. OK for the next, that I made that I had uninstalled my previous ATI Radeon X 600 series drivers and Yes, they were gone I also ensured that in my BIOS, this graphics card was elected s and when it does not work I went back to "automatic". Still does not work, the monitor says no signal it stays black. I tried to install drivers before I put the video card in and that has not worked, I tried to put the card in and remove the cmos battery to see if it would work and that SO it did not work, either I am completely frustrated and it was my birthday present and I was very happy to receive now really upset! I know I should of treated Tigerdirect! I bought the video card in DiamondMultiMedia on eBay, that they had a positive rating of 99% so I thought ok good deal lets roll. After all this, I called support and the tech told me as if I was a student of fifth to which I informed him that I had tried everything. He wanted to give me another card but I have to pay the shkpping return this Radeon HD7750 and then they send me another lmao graphics card I said no as I want my money back on my card! Do not buy this is not going in the Dell OLptiplex 755 MT
