my compaq system won't turn on. it simply shut off while working with the two led lights in the front full on. the processor fan and the power supply unit fan are constantly running.

i already did some troubleshooting on the system, but no success.

i suspect the power supply unit, but need guide on how to fix it. am average electrical electronics engineer, and would appreciate any help that can confirm the PSU good or bad

Thanks

have you tried reseating the memory? – Owen Nov 5 '10 at 5:55
this is not memory problem. I was using it and it suddenly went of without shutting down. the two fron led is on and constant. not even blinking as it use to sometimes – Smith Nov 9 '10 at 19:02
