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???

Re: Dell Optiplex GX280 boot-up problem


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.

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.

Re: Dell Optiplex GX280 boot-up problem

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

you are probably using a usb keyboard....plug in the ps2 keyboard(the round one) and it will pick it up.Some wont have the correct drivers for theafterhourspc_1.jpg usb until it boots. PS2 LOOKS LIKE THE ONE ON THE LEFT AND USB IS ON THE RIGHT.

Six beeps at post and no joy with boot up

The exact meaning of the beeps for Dell depends on their... rhythm.

Six beeps might indicate a simple CMOS failure caused by a bad battery, which is easy to replace.

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.

Goes On ..Then Goes Black Screen I have 2 GX280s. One failed the other day after 2 years use. The BIOS screen appeared then it all went black. About every 10th attempt to get it going, it works and boots...

have you tried booting in safe mode? When it starts press F8 and select "Safe Mode" or "Last Known Good Configuration.". On that 10th try you do get it to come up make sure you install all updates for your computer. Then you can put int he Optiplex disk from Dell and run some diagnostics.

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.
