Hi all, i hope some can help me out here 
For some unknown reason my computer has started to just reboot for now apparent reason.
System Spec:
ASUS M3N-HT Deluxe Motherboard
AMD X2 6000+ AM2 Processor
Artic Cooling Freezer 64 CPU Cooler
8gb OCZ Platinum PC6400 RAM
XFX 9800GT 512mb
Primary HDD - 500gb Samsung F1 HDD SATA
Secondary HDD (Media drive) - 500gb Samsung Spinpoint HDD SATA
OCZ Powerstream 600w PSU
Windows Vista Home Premium x64 (OEM)
I only upgraded to 8gb of RAM about 2 weeks ago and it worked great but i thought i'd still better check it so i removed it 4gb of it and tried it again and still getting restarts, i then put my old 4gb set (4 x 1gb OCZ Platinum) and it did the same again.
Since that didn't resolve it, i decided to check my CPU and GFX temps. The CPU idles at 32c and 45c under heavy load, and the CPU doesn't go above 60c under heavy load.
The system is completely upto date i.e. bios, drivers and OS are upto date and i'm now completely stuck for ideas of where to go next
I can't find any windows error logs related to the random restarts, are they stored in a different place in vista or something?
Also the system does not show a blue screen so i can't write down the error code from that.
Any help would be greatly appreciated
Thank you
