Help - PC Rebooting Problem

[colin2k7]

For a while now my pc has start rebooting itself randomly. At first I thought it might be a windows problem as it only occurred when windows was already booted. Now however, when it turns back on after rebooting , it cuts out while running through the bios and can repeat this multiple times.

This was my first build which I built 6 months and had been working perfectly until the problems started around November.

I have tried reseating the cables but no luck with that. My next guess would be either a problem with the motherboard, PSU or RAM but not really sure.

I have been trying to check the RAM but can’t get the system to stay on for long enough.

My Rig,
Cooler Master 690
Intel i7-920
6 GB corsair 1600mhz DDR3
Gigabyte GA-X58A-UD5
750W Corsair TX
40gb Intel SSD
2x 1TB F3 Raid 0
HD 5770

Cheers,
Colin

Are you overclocked, try running at stock.

With the ram try each stick individually and download and run mem test.

Try a CMOS reset and see how it goes there.

Take everything out of the case and test the system, could be faulty switches on the case.
