Hi there is one more thing you should check before buying another mobo. Trace the wires from your on/off switch on the case, unplug it and then bridge the 2 pins out with a screw driver, this will start the computer. runit as normal, then shut down and see if you get a restart. If the computer does not restart on its own you have a faulty switch. Clean it or replace it. Regards mistyman

Try updating the BIOS. Seems there were some advanced power management improvements.
The following changes were made to the A04 BIOS for the A06 BIOS: 1) APM issues device commands in SMM. 2) Fixed APM to issue power up/down commands to peripherals in SMM. 3) Turbo/Deturbo switching done in SMM. 4) Implemented <\> Turbo/Deturbo hot key. 5) Password checked after exiting Setup and before OS booting. 6) Fixed the problem with #9 GXE64 Video card losing its video at the end of POST. 7) Fixed the problem with WINICU having General Protection Failures. 8) Fixed the problem with Real Time Clock not being updated correctly when in Power Managed mode.

You hit that one right on the dot. ATI website showed the specs for that graphics card you installed as needing a 300 Watt power supply. Good news though... I researched newegg.com and I believe I found your 300W power supply. There are 4 different Optiplex gx280 designs with 4 completely different power supplies. Since you bought the low-profile video card, I believe you have the slim computer case and this power supply should work for you...

You problem is most likely caused by faulty capacitors on the motherboard. Most PCs of your age suffered from this. It was a manufacturing defect. Call Dell to see if they will replace it for free. This is a picture of two blown caps so you can id them on your MB
