I didnt know exactly where to ask this, but this seems to the best place. I build my system about a year ago and it has run fine untill about 3 weeks ago. it started with a blue screen. Then every couple days or so my mouse would freeze up, then the whole computer, but if i waited like 30 seconds i could move the mouse again but it lagged froze constantly and was always the wrong cursor(Ex. the "I" for typing when hovering over the start menu) When it is in this stage the only way to turn it off is to hold the power button. About half the time after this happens, when i turn the computer back on my bios will tell me overclocking failed, i don't overclock anything. Also sometimes when my computer falls asleep it wont wake back up without turning it off. My system consists of
Asus-P9X79
GeForce GTX 560-TI
Intel i7-3820 cpu
8192 kingston DDR3-1333 ram
H60 corsair liquid cooling
750 watt peak atx power supply

Anyone of those problems occurs ever 1-3 days now. Everything should be up to date, and i have run scans and disk defragments on my hardrives, I have no idea what to try next.

This has all the marks of CPU instability, which can be caused by mainly high temperatures or low voltages.

Of course, I always recommend dusting out the PC. The other thing to try is a burn test to make sure your H60 is properly installed and can handle the high loads.

Download and install HWMonitor, which show system temps. It's a lightweight tool, so it retains accurate readings with very low overhead.

Then, download the Intel Burn Test. It uses Linpack, which pushes your CPU harder than just about any other benchmark can.

Run the Intel Burn Test while monitoring temperatures. If they're going through the roof (like past 85 Celsius) you know that's what's wrong.

If your temps are fine, then, for whatever reason, the voltage being supplied to your CPU isn't enough. I'm not sure why this would happen, unless... what kind of power supply do you have. You just say 750 watt, but not any kind of brand. That could be the issue: a bad PSU.
