Hi guys, hopefully I can get a bit of help with the problem I'm having overclocking my i5-760. So, basically the problem is that no matter what overclock I put into my CPU, I've had it stable through hours of stress tests at 4Ghz or 3.8Ghz, for some reason it will randomly hang in Windows when doing just plain innocuous things like surfing the net or doing nothing at all. It happens randomly, it might happen after 30 mins, or it might happen after 2 hours, but it always seems to happen. I'm really at a loss. It's not like it's an unstable* overclock - it runs stress tests fine and I've never had it over 65ºC and never had a BSOD. It's essentially a fresh Win 7 install too. I've disabled Turbo Boost, but suspect it may have something to do with the other power states and options as in this screenshot: But running a overclock with these disabled still hangs. Maybe I should be running it with C1E & C3 etc enabled? Thanks for you help. * Of course it technically is an unstable overclock, but whatever.
