ok, i recieved this computer from a friend that said his computer just wouldn't turn on one day. he said it was probably the monitor so i took the cpu and the monitor to test it. the monitor works fine on my computer so i tried his computer on my monitor and it still wouldn't work.
let me backtrack a little, when you turn on the computer, you get no post beeps, i don't think you ever do with stupid dells. the display never comes on the monitor, ever. after it's powered on, all of the drives will light up at the start, just like a normal boot, no beeps, and both cd drives will open, and i get the green light on the motherboard. i've tested the video card and the hard drive, both of these work and a working video card won't work in the computer's agp slot.
the only thing i can think is the computer is really dirty and it seemed like the exhaust fan and the powers supply fan were struggling a little to turn, maybe the processor overheated? maybe something failed on the motherboard? how would i find out which of these is my problem?
this is a really dirty computer
