Cold Boot Trouble

[xanoth]

One of my PCs wont boot after it's been off for a few hours.


No recent changes
Stable for days if not turned off
No loose connections
No performance loss
No recent crashes
Lights show power to the motherboard and network even when it won't boot.

Help much appreciated so I can diagnose this before it stops working at all.

Please post your system components.
Be as detailed as possible and be sure to include your PSU and any overclocks.

Your problem sounds like a PSU " power good " circuit fault with a component probably a resistor changing it's value with the temperature. If you know electronics it's easy to fix, if you dont than replace PSU. Cheers
