    I also have a GX280 with this problem. I have just turned it on after 2 months being away from home and nothing appears on the screen unless I press one of the little configuration buttons, when it says "In PowerSave mode ..". Nothing happens when I move the mouse or press anything on the keyboard. Also, one of the fans inside makes a lot of noise. My A and B buttons are yellow and Cand D buttons are green. Inside there is an orange LED by the memory slots which is always on whilst the power cable is plugged in.
    I would really appreciate any advice - I thought this was a pretty good machine until now. I bought it second-hand 6 months ago; it has XP Professional loaded.

    Best wishes,

    John

Well seeing as how im Dell certified, I can help you or you can go to the dell support site and look at the error code manual and it will tell you.

http://support.dell.com/support/downloads/index.aspx?c=us&l=en&s=gen

and heer is directly to the light diagnostics information, read it and find what is closest to what you have.

http://support.dell.com/support/edocs/systems/opgx280/en/ug/tools02.htm#wp1114432

Go to system trouble lights.

Most likely you have a bad memory stick or the mother board is going bad.

Im pretty sure your warranty is out, unless you have an extended. You can check the warranty infomation by entering the service tag number at support.dell.com Or just give it to me and i can check for you. Its a sticker on the back with a bar code and about 7 digits or so, kind of like ( 071BH7) or something simialr.

Also, Dell has had a major problem with that model and the mother boards blowing capacitors, Once we know what the issue is, hoepfully we can get this resolved.

What type is it, Small form factor, Desktop, Smal form desktop, Tower ?

Let me knoe, and we can get going.

Hello here is the home page:

http://www.dell.com/support/drivers/us/en/ussoho1/Product/optiplex-gx280

I think you have some kind of a virus or malware on your system.

Install this program and make a full scan:

http://www.malwarebytes.org/products/malwarebytes_free/

You maybe have to start the pc in failsafe mode by pressing F8 while you reboot.

Install also a better FREE antivirus program:

http://www.microsoft.com/en-us/download/details.aspx?id=5201

Please uninstall any other antivirus programs before you install microsoft security essentials. Run a full scan when installed and updated.It`not great to have more than one anti virus program installed. Most antivirus programs have a background scanner running to protect you from virus vhile you surf on the internet open a file etc.With more than one antivirus program the pc`s performance will be decreased.

There are a lot of things that can cause a computer to shut down.This could also be the power supply.Try also to renew the thermal grease between the cpu and the fan but BE CAREFULL not to damage the cpu.
If you are unsuccessfull at resolving the problem visit a computer repair shop.

When you talk about checking memory, it's the physical RAM stick inside the computer. RAM does not have sectors like a hard disk drive. If it does happen to be bad I'd replace it with at least 1GB to 2GB. 512MB is really low.

Good luck

Increase the amount of shared video dell gx280


Hello!

Don´t lose time for that, I think that you have integrated grafik in own chip, and they have same options with 1 or 64 MB, option in bios, that isn´t a standard shared grafik. Try AGP card if you have a socet for that.
