PC wont booot....
Posted: Thu Nov 19, 2009 5:14 pmHowdy..myy father in-law's Pc crashed the other day and i was given the job of trying to sort it.
basically, it got the BSOD from nowhere..no hardware or software installed. When he tried to re-load windos from a CD it made an attempt to boot from CD then swithched off. Now, it tries to boot for between 5-20 secs then switches off.
i took out RAM, graphics card and same problem. I disconnected the power supply to test it and i'm getting the correct 12V, 5V and 3.3 V from the respective 20 pin connector.
I'm stumped...any ideas?
EDIT: WHile the 20pin connector was connect to the motherboard i was getting 3.3V on the 12v & 5 V rails. It was only when i disconnected the connector from the board that i got the correct voltages ( i shorted out psu_on to Gnd to spin up the PSU).
