I have a Dell Dimension 8200 which I have had since about 2001. 6 months ago, I went to go boot up my computer, when I pressed the power button the Bios beeped. I shut the computer down and tried again, the same beeping had occurred. After trying 7 or so more times, it finally booted up. Once the computer boots up, everything runs fine and like it should. This last week however, it has not been able to boot-up.
The Bios beeping code reads 5-2-2-1 which I found translates to "unsupported or mismatched memory". The diagnostic lights on the back of the computer reads a-orange, b-orange, c-green, d-green which I found translates to "memory failed to be sized or enabled"...While the Bios is beeping, my computers fan kicks on full blast and will not stop until I turn the computer off.
I have tried blowing out the memory slots to free any dust that may be causing this; I have also pulled the Bios battery for 20 minutes to reset the Bios. I have also tried a different hard drive and a different power supply. All of my ideas have resulted in failure.
I have not upgraded or done anything with my memory/RAM. The only thing I have done to the computer is installed a Radeon graphics card and Antec power supply in 2004. I have had no problems prior to the bios beeping which like I said, started about 6 months ago. I have run out of ideas on how to fix this. Any suggestions/help would greatly be appreciated.
Thank You
