yesterday I did monthly computer dust cleaning. I removed CPU fan and graphics card to clean them more easily. When I put it back in and turned on computer I was in for a treat. Nothing displayed on a montor, just fans spinning as ast as they can.
At first Dr. Debugger was stopping at code 85. I resloted the graphics card and RAM and cleared CMOS by pressing the button behind. Still no change so I took out the processor to see if I messed u the pins when I was putting fan back on. Everything was fine but when I turned computer back on it didn't stop on code 85 anymore, it went to 00 and it displayed first windows screen after booting is done. It stopped there for like 3-4 seconds only to go back to code AA and black display alog with fans on max speed.

I've had this computer for almost 2 years now (2 years in 11 days) and never had any problems before nor did I overclock him.
