if your system has two dimms take one out and run memtest86 if it passes swap the ram and rerun. if the system only fails with two dimms installed check that your mb bios is up to date and with cpu-z the dimms are running at the right speed.
Hmmmm......have run memtest86 with no failures. This is a brand new build and the BSOD's have only been happening the last few weeks. System had been fine for first few weeks. I enabled Driver Verify and I got a BSOD as soon as the system booted up informing me that a faulty driver was the reason. I analysed the crash dump and the faulty driver is ndisrd.sys? Appears to be Realtek Semiconductor Corp from checking the file properties?
