my question regards testing if a cpu and mobo are functional.
Functional:
Power Supply
RAM
Items in question:
2.5ghz Celeron
Mobo (from eMachines compter)
When the PS is connected to the MOBO, the LED on the front of the
computer (indicating power) is lit. When power switch is pressed (to
boot computer) nothing happens. Fans do no spin, ect.
Failed repair attempts:
1. Switched the power switch
2. Put CPU into an old P4 compatable board running a 1.8ghz P4 with
512MB pc133 RAM. Computer boots, but hangs. No video signal. Perhaps
FSB / RAM is incompatible?
CPU shows no signs of visible damage. I am unaware of how the PC
reached this current state. Best guess is some type of power surge, as
i had to replace the PS.
Are my MOBO, CPU, or both fried?
any information you can provide is greatly appreciated.
It's doubtful that they are fried, and the CPU test you used would
probably fail due to the fact that your old pentium 4 board was not
intended for a celeron processor so yes FSB n stuff would be off...i
would tend to think the mainboard's fried because it failed to even
turn on the rails in the power supply (no PWR_GOOD Signal), I would
suggest testing your power supply from the celeron system in another
ATX machine WITHOUT the celeron in it (use known working CPU), if the
supply still works then it's probably your board...your CPU (the
celeron) should still be OK
