Question about Dell Optiplex GX280 (99301) Motherboard
I HAVE A GX 280 AND WHEN YOU POWER IT ON IT HAS NO VIDEO AND THE CPU FAN RUNS WIDE OPEN AND IS VERY LOUD. IS IT A PROCESSOR PROBLEM?
100% motherboard issue guys. The dude above that said flash the new bios should realize that when you CANNOT post a machine you CANNOT flash the bios unless the bios chip is removable and you have another machine to flash it with. The only fix for this is a new motherboard.

This problem is normally due to some bad capacitors in your motherboard. Dell is aware of it and as a computer tech for 18 years, it's one of my biggest problem were I work.
Please check the capacitors that are closest to the fan. If you see capacitor are blow-up or bad that is your problem, and they most be replaced. Here is website that would help you in how to change it http://www.thecapking.com/. Good luck

After flashing a GX280 from A04 to A08, the system would not reboot iknto XP. Had to unplug it to shut down. When powered back on, it then sounded buzzer like beeps and the green light in front flashed. The fan went into afterburner mode. Unplugged the machine and took out the CMOS battery and powered it on without a battery, and it tried to post up. But unable to enter setup via F2. I then shut it down and replaced the battery. Then let it do its thing. Finally able to enter Setup. I could see it was now A04 again. Tried to flash with A07 successfully. Reset date and time and check other settings. It appears to be okay now! No removable CMOS chip that I could see, no fried capacitors apparent, otherwise it would not boot!

Since no CAPs were bad on mine, I replaced my power supply, running fine again

Download the A07 BIOS, and everything will be fine! A08 is causing CPU FAN issues.
