|HI so im confused about this.|
I am fixing my friends computer that wouldn't turn on. I have a few spare motherboards and a spare psu. Turns out the psu was dead.
Now with the spare psw 230w the mobo will turn on. But the monitor wont turn on. Tested on 2 monitors.
I thought that was strange, so I tested the monitors on 4 other motherboards and they wouldn't turn on. 3 motherboards are using onboard graphics, and 1 is using a video card. The monitor's will however turn on with my newer computer.
The motherboards that wont turn the screen on are old (but still working) using intel p2 and p4 cpu's. The one that will turn on the monitor is a more recent computer with its own psu (unfortunately my new psu has more pins and cant be tested on the old boards).
So im confused... the common problem with everything that doesn't work, could be the 230w psu, but still turns on the motherboards. Could the psu turn on the motherboard but not power op the on board graphics ? if so even on my old intel p2 ?
I cant get hold of another old psu without buying one.
Hope that make's sense. Any suggestions ?
