Dell Optiplex GX280 boot-up problem

I'm having a boot-up problem with this Dell OptiPlex GS280, Everytime the WindowsXP screen comes up the machine locks up, no keyboard function would work nor would the power switch on the front. I would have to physically remove the power cord to shut the system down.

I've removed every piece of hardware to diag this problem...Can someone HELP ME???

    XP screen stays on for less than a second then the screen goes blank and i'm unable to power down the machine using the power button or the Ctrl+Alt+Del, there's no response from the machine.

    There's no blue screen, it only ask to choose a last known good configuration, safe mode etc.

    Would this be motherboard problem? cause all the lights on the back are green.

    Many thanks.

    I used the last known good config.
    I also tried the Safe mode but did the same thing.
    Installed a new HD and fresh install of XP, but it won't complete the installation.

    I'll try that and let you know....just about ready to throw out the window.

    I tried doing a Win 2000 install, went through the formatting ok but when it was time to install windows and its drivers, the machine went off and locked up as it used to.

    I give up, I think it's time for the trash.

By and large, system files which are missing or infected with viruses can result in a Dell no boot situation. In that case, we can assist you to find the missing DLL files. If by chance, your Dell PC is not booting then we can try to use certain commands to boot in Safe Mode. At times, Windows OS may not allow you to boot in Safe Mode.

Apart from this, Dell no boot issue may occur if the disc drive or a USB drive is in use. This can happen if the bootable device order is modified. To get rid of this issue, we can suggest you to change the bootable device order from BIOS and allow the hard drive to boot along with Windows OS.

Get more information to fix Dell Boot Problem. Hope this information helps you.

Guess what? it's the CPU. Changed it with a working PC same type and unit boots up fine. Guess we learn about new problems everyday.

I think it's high time these units start telling you what component or section of the computer is faulty...too many things to diagnose.

Check out Dell's own tech forums. Seems some of the very early ones did have motherboard problems, if I recall correctly.

Im guessing its a memory error, that's the most common casue for these sorts of issues such as the one im working on here in the shop...however this one may be bad motherboard. I get bad mem errors in memtest86+ but even after changing ram locking up and losing memory in kernel exception not paged BSOD

If you get a blue screen, find out what error code it is, or see what files are missing etc, and google it. see what it comes up with and way to fix it. if the blue screen doesnt come up, explain in more detail please, of what happens after the xp screen.

    hrmm. what do you select when the screen comes up with 'last known good configuration, etc' ? it could be xp itself.

  • iqbal ibrahim Nov 29, 2007

    erm you could try installing an older version of windows, like 2000 as it is the most stable os as far as i know, and then after installing that, upgrade back to xp. i know it's long but it could help to find out if its the motherboard or not.

Dell optiplex gx280 makes loud fan sound at startup and enters windows screen, but will not finish booting and freezes up.

You may have a problem with your power supply(the loud fan noise) and eventually it may get too hot and will cause problems like not fully booting.

My pc keeps on restarting.

Tap the F8 key when booting up. This brings you to a screen with different options. Choose Use last known good configuration. this should solve the problem. Your system is stuck in a loop.

Same problem... orange power light, fan starts slow and builds up to very high speed.
I removed my video card and SIMMs --> it beeped on boot and the fan did not speed up.
Put one SIMM back in --> booted fine, pressed F2 to view BIOS. Memory reported fine.
Put all SIMMs back in --> all fine now.

Audio driver is not installed

i have the same computer (dell optiplex gx280). yeah windowsXP does not support it so i went to to download the sound driver for my model and it worked well. i think its the ADI 198x Integrated Audio Driver.

follow the link below

if the link does not work then you have to do it manually. go to under support/drivers and downloads. just follow instructions. choose desktop and then the model. afterwards it'll show the drivers selection.
