2 times now my machine has randomly restarted. Both times I was using IE7 when it happened. Usually I would suspect RAM - but the machine can run Prime for 12 hours without error and is absolutely stable in games. I am overclocking slightly, but again, all tests pass OK. Could be PSU I guess (X-Clio Stablepower 460W) but it doesn't "feel" like that to me. Heat is also a none-issue.
Any other ideas?
