CPU Dell Optiplex 755 problem

Hello, I was told in one of the forums that a PROCESSOR Intel CORE 2 QUAD Q9650 SLB8W 3.0 GHz, 12 MB CACHE 1333 MHz FSB would work in my office. I bought on E - bay and installed with the bios already upgraded A22. It did not work. I tried to install my original CD which worked and now I can not do, even after. I removed the battery for an hour and that did not help. I tried a different video card in case that was the problem. I get absolutely nothing on the screen. I am at a loss. Does anyone know a thing or two to get it back running. I thank very you much for your time. Robb

What error POST or the diagnostic lights get you that indicate an error?

  • Memory Dell optiplex 755 problem

    I recently acquired a Dell Optiplex 755 used with 4 GB of memory Kingston (KVR800D2N5K2).

    I replaced it with 8 GB memory Kingston (KVR800D2N6).

    When I plugged in the computer, it went through it, self test has virtually stopped with just the power led (green) and I could not activate it (no follow-up post). I quickly removed the memory and give the original 4 GB and got on with the post office to come fine.

    My only question is to go from CASE 5 6 because the problem or is the memory just bad?

    Thanks in advance.

    Found the solution, when I asked questions about memory, I discovered it was the memory of type AMD. Where the reason for which he would not start on the motherboard Intel 755.

  • 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!

    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.

    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

    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?

    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.

    Any knows is Dell Optiplex 755 is compitable with ESXi server?

    When I want to install ESX 3.5 update 3 on the Dell Optiplex 755, it detects drive hsrd (WD), I don't know what to do?

    ESXi is detecting disc hard but not able to configure network & with ESX 3.5 update 3 does not detect the hard drive.

    Help please.

    Kind regards

    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.

  • Second choice HD for a Dell Optiplex 755

    Hi all

    I just bought a Dell Optiplex 755 to replace the Zino HD 400, which eventually gave the soul. My question is: can I use the hard disk of 1 TB of the ZINO as second player for the 755 and can I buy a plug adapter for the second span Prewired in the 755 that would fit the Zino HD?

    Thanks for any help you can give.

    Will be

    Looks like the Zino has a SATA 2 HARD drive, so you shouldn't have any problems in the 755, unless you have the screenshot form factor that supports only a SATA hard drive, and you may have to remove the floppy drive the other models of form factor, if installed, to make room for a second HDD.

    You will probably be able to use the same data the Zino SATA cable the 755. Read the Manual for more information on the installation of a second HDD in your specific form factor.

  • Dell OptiPlex 755 SFF rear disc HARD fan Press F1 CORRECTED an error!

    EDIT: Fix for F1 error is on the #2 post. Try only if you know what you are doing and don't mind not having is not a HDD stupid fan. I now only use a SSD and it needs no power noisy fan to waste.

    ORIGINAL MESSAGE:

    I removed the fan hard drive dying on the Dell Optiplex 755 SFF (fan is built in a hdd cage) and modded the side of the case to include a Yate Loon 120 mm fan. I removed the hard drive in its entirety and then used cage the where the floppy drive has been to place my SSD 256 GB of free space. The system is much more pleasant that way, and now he has place for 120mm fan (already modded).

    However, at startup, there is a rear fan error and it asks you to press F1 to continue. It disappears when I connect the old dying noisy fan (has more room for it). Because I don't want the hard drive cage (or his fan also) and I can not put the fan back in, I want to use the connector and the son of the old fan dead and hang it in my nice new Yate Loon, which is the ideal solution for cooling (used as a suction fan).

    The color codes are:

    Yate Loon (D12SL-12): Red = 12v, black = mass, yellow = Tach (I think)

    Dell drive HARD fan (STROKE BN06015B12H): Red = 12v, black = mass, yellow? Blue? (PWM or tachometer)

    What are the blue and yellow for the Dell HARD drive fan? Can I just plug the Red of Dells Yates red and black wire on black? This should give me a 12v fan work, however I wonder if the loons Yate flying over red wire could be used for the sensor.

    Any help would be great. Really sad that Dell did not include a fan setting ignore in the bios.

    Thank you!

    SkOrPn

    EDIT: Ok, Yate Loon do not light up when it is connected to the fan header. What is missing? The old fan of Dell is rated 12v A 0.36 and the YL is 12v 0.30 A, less than the old fan so the fan header would seem like the logical place to get needed power as it provides much. When the old fan is plugged it provides 12v, but does not provide power when Miss the blue and yellow wires?

    Edit2: Ok, understood as the Yate Loon uses the Red wire as the 12v fan (somehow, I thought it was yellow). Now, I think that the yellow must be a son of tachometer for rpm. Now I'm wondering if the Dell system can monitor the number of TOWERS to connect the yellow wire without prejudice to the system without the connected blue. In fact, I wonder if the controller monitors just RPM to warn of the fan failure. If so, maybe I can connect the yellow and get rid of this error from the BIOS at startup screen.

    Hello

    I've linked yellow pine of wire of the connector of the fan HARD drive on yellow pine of the CPU fan connector and no fan of F1 more at startup error -correction

    I have no need for my SSD disk drive hard noisy fan.

  • 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.

    • Reboot several times, and then try again.
    • Disable the general USB peripherals (for example - smart card reader).
    • If you are using a SCSI drive, make sure you have the drivers available for your storage on a thumdrive device and it is connected. During the installation of Windows 10, click on the advanced custom Option and use the command load driver to load the driver for the SCSI drive. If this does not work and the installer still fails, consider switching to an IDE based hard drive.
    • Perform a clean boot, restart, and then try again.
    • If you upgrade to the. ISO file, disconnect from the Internet during the installation, if you are connected in LAN (Ethernet) or wireless, disable both, then try to install.
    • If you are updated through Windows Update, when download reaches 100% disconnect from the LAN (Ethernet) Internet or Wi - Fi, then proceed with the installation.
    • If this does not work, try using the. ISO file to upgrade if possible.
    • If you are connected to a domain, go to a local account.
    • If you have an external equipment, attached to the machine, unplug them (example, game controllers, USB sticks, external hard drive, printers, peripherals not essential).
