Whenever my friend tries to turn on his computer, all the fans start and hard drive start spinning, but nothing appears on his monitor. What's really weird is the computer starts up as soon as it is plugged in; the power buttom is never pressed.
I've tried:
multiple monitors
a different working power supply
a working X850XT PCI-E
a GF4 MX420 PCI graphics card
using only one stick of ram at a time in the first slot
All of that didn't change anything
I even switched the Pentium 4 630 with a Pentium D 820, and the only change is that the computer shuts itself off after about 30 seconds of being on. (Still nothing on screen)
What do you think I should do?
Comp Specs:
Intel Pentium 4 630
Asus P5LD2 (using a 20 to 24 pin power adaptor with it, would that cause all these problems?)
Corsair ValueRam 1gb 2x512 PC2-4200 in dual channel
Asus ATI Radeon X700 128mb PCI-E
WD 80gb SATA hd
NEC ND-3520A 16x dvd burner

Previous history with the computer: When the computer was originally built, both motherboard and cpu temperature readings were wrong (unless they're over 90 degrees celcius right when the comp is turned on -- so I disabled the temperature sensors). Over the last few months, the computer has just been shutting itself off randomly. I tried stressing different parts of the computer using various programs, and whenever the processor was at 100% cpu usage for a like a minute, the computer would shut off.
Then it just wouldn't start up one day and I'm at the problem I described above.

Sorry that this is a repost from the general hardware category, I forgot there was a technical support category too.
