Win7 x64 hangs during idle
Hey guys, first post here xD
I have Windows 7 Ultimate x64 installed on a Corsair Performance3 SSD which is a little over a month old. About a week ago, I started noticing that windows would hang after leaving it on overnight with an un-intensive game running in windowed mode. A couple days ago it started hanging after idling anywhere between 15 minutes to an hour. WHen it hangs, I can open new tabs in Google Chrome but nothing will load and the cursor will change to the spinning circle and when I right click the desktop, the menu will appear but nothing will happen if I click anything... same thing with the start menu and taskbar. The activity LED on my wireless card continues to flash though.
I've tried disabling every power saving option in bios and in power management under the control panel, disabling the shutdown of my wireless card to save power, disabled all non-Microsoft services with msconfig, ran Memtest86 for 4 hours with no errors and finally, in frustration, reformatted and installed a fresh copy of Win7.
I have no idea what's causing it. Any ideas?
My rig: i5 2500k stock, 2x4gb Corsair Dominator DDR3 1600, Asus Sabertooth p67 rev. 3.0, Asus GTX 570, Corsair Performance 3 SSD 64gb, Corsair HX850w power supply.
