When I switch on my computer, it 'fires up' then powers down after 1 or 2 seconds. Yesterday it did the same but eventually started. Later in the day I changed the processor, switched the PC back on and it started fine. Now this morning it won't start again. I think(hope) that it is the switch on the case. Anyone got any suggestions other than replacing the case?

I need my PC for work so I need a fast confirmation or answer.

Thanks in advance

welcome to the forums perquaine

do you have a heatsink + fan properly mounted on the CPU ? what might be happening is that the heat is not being drawn away from the processor as it should be so it shuts itself off as a precaution...if you have a fan on the heatsink, check if its working properly...can you post more specs. on you system btw....

If you've checked all the connections, I'd start with the power supply. Since the processor is just starting up, I wouldn't think overheating in a couple of seconds would be an issue. The ATX switch is a momentary contact switch. Since the switch is sensed enough to start, it's not the switch. Check all connections first...

Non start on switch on

Just to say thanks for the replies. I actually bought a new tower with power supply and it solved my problem!!

It did take a while to transfer my M/B and hardware across though.

hope I can help someone inreturn someday.:winkgrin:
