Hi all, After searching for a forum with lots of active support, I found it. Seeing this crash has various reasons I couldn't find a fix from other topics. I just built a PC for a client and it's getting random restarts. System: Windows 7 x64. Intel i3 530. GeIL GV34GB1333C9DC 4GB (2x2GB) DDR3. Seagate Barracuda 7200.12 500GB ST3500418AS. Gigabyte GA-H55M-S2H mATX Motherboard. Samsung SH-S223C SATA DVD/RW Drive. All temps are always under 40 Degrees Celsius. The original power supply is a Thermal Master 420W, replaced with a Thermaltake Litepower 600W. The problem still occurs. I have done a individual and paired Memtest and the Memory is fine. CHKDSK finds errors and cannot continue, so I done a CHKDSK /R There are no Minidumps (Yes the reporting settings are right). CHKDSK /R took a while (1 Hour+) and it didn't crash. Usually while your in Windows 7 it crashes every 10-15 minutes, so could this be a driver problem?

Any help or questions trying to resolve the problem would be greatly appreciated. Edit: After the CHKDSK /R, CHKDSK was fine and the system has been up for half an hour, I've got to go out to dinner but I'll leave the system on and see if it crashes with some applications open.
