Strange problem

[killer_uk]

Hi,

I have a strange problem that is when I switch off my machine and then switch it back on lets say.....10 seconds later, I get blue screens when booting into windows and my memory fails the memtest diagnostics.

If I then switch the machine off for 30 minutes or so and then switch it back on, it works flawlessly?

My system runs great the rest of the time and my memory passes memtest without a problem, it's ONLY when I shut down the machine and then switch it back on without leaving 5-10 minutes inbetween power on and power off. It even reboots fine the rest of the time. My all important specs:

E6600 (Stock)
Gigabyte DS4
X1900XT (Stock)
Corsair XMS2 PC5400 (Voltages have been checked and raised and the timings are correct)
Tagan 580W PSU (Voltages are fine)

Any ideas?

Well I'm still having this problem, so I apologise for bumping this old thread. I'm certain its the power supply now as games run sluggish then crash, then the entire machine powers off and then turns itself back on again. Does anyone else have any other ideas as to what it could be?

I've also noticed that the link light on my router, indicating my network cable is plugged in, is no longer lit when the machine is off, when it was before. The first time this happened was a few days ago and since then I've been getting more and more strange problems.
