If your PC shows the classic symptoms of a PSU problem I have a TFW-Labs approved work around to get your PC booted.
This applies only to the situation where you power up, the fans spin briefly then the PSU shuts down.
- Unplug every power connector except the Motherboard
- Power up and let it finish griping about no hdd etc
- connect everything up while its live
- hit the soft reset and watch it boot
I have no idea why my PC does this, spent £65 on an Antec truepower and it still does it. The above method got things running at Mojos last weekend and the one before that. I was blaming the Ebuyer cheapo PSU but a posh one is no better.
This shows that it doesnt get switched off very often
