Hi, i have an i7 920@ 2.67ghz and 6,0gb ram. Sometimes and specially when i shutdown my computer, on the next day, the computer crashes 1-2 times, and then it never crashes again. Its rly annoying, i tried to run memtests at the Memory and the program always stops working at some point of the test. i have run S&M and mem test from hirens boot cd. I dont know what to do anymore. Can it be something with voltages or a problem with the slot\memory dimm itself? thanks
