Have My PC overclocked to 2.6 now (237 x 11 @ 1.47v) and ran Prime95 last night for about 9 hours and everything passed. Ran memtest along side it for the first 2 hours. Zero Errors. Was very happy with the results and decided to run adware, spyware, and antivirus. ran adware and locked up half way through. now everytime I reboot and when windows loads it locks up right after trying to open up a program or more or less anything. Wanted to know if maybe one of my HDD are going bad. Or is there any effect of Prime95 running on dual core CPU cause I notice when its running its splitting the load over the two cores. Should I be running two copies of Prime95 to fully test the system?
