Hi guys, I'm at a loss as to what's wrong with my computer and I'm hoping someone here can help point me in the right direction. Problem: computer hangs and crashes after roughly 45 minutes to 1 hour. No bsod, just kind of stops working. No indication whatsoever that it has crashed, other than that all programs stop working. CTRL+ALT+DEL doesn't work and I end up having to do a hard reboot.

I've run a number of diagnostic programs to see what might be causing the problem.

CrystalDiskInfo says the health status of the SSD and my secondary 1TB hard drive are both good with temperatures running more or less at 30C.

I've run Windows 8's memory test and it showed that there were no issues with my memory.

After keeping an eye on my temperatures using Core Temp and CPUID HWMonitor, my cores are around sub 40C up until the point it crashes.

Graphics card also sub 40C up to the point it crashes.

I read somewhere to check the +12V on my motherboard and Piriform Speccy shows that it's 12.184 V (which IIRC is okay).

**EDIT**
Ran Memtest86, showed that my memory was fine
re-clocked my RAM to 9-9-9-24 @1600MHz as was suggested (DRAM frequency on CPU-Z still shows 796 MHz but I think that's to be expected?)
Updated bios and all drivers, turned off power saving settings, still no good
**/EDIT**

As far as troubleshooting directly with the hardware I haven't done much of it (since I'm not really sure what to look for). I've tried re-seating each stick of RAM to make sure that it's in securely and it's fine. Did a quick look at the motherboard, nothing looks weird or smells different to my untrained eye.

I haven't tried a stress test to see if that's the reason, but regardless of the load I put on my computer it will freeze/crash at around 45 minutes to an hour. Sometimes if I'm just sitting there browsing the same website it won't really be noticeable, but when I focus on a different program or tab it will start to freeze and I'll have to do a hard reset.

I've tried reformatting my system but no luck, same issues.

Can anyone point me in the right direction?
I'll list my system specs below:

OS: Windows 8 Pro 64-bit
CPU: Intel Core i7 950 @ 3.07 GHz
RAM: 24 GB Triple-Channel DDR3 @ 530 MHz (7-7-7-19)
Mobo: EVGA X58 SLI FTW3 (Socket 423)
GFX: 1024MB NVIDIA GeForce GTX 560 Ti (EVGA)
HDD: 932GB Hitachi HDT721010SLA360 (SATA)
119GB M4-CT128 M4 SSD2 (SSD) (my OS boots off this)
Cooling: Corsair H50
PSU: Corsair TX650M

***EDIT***
Here are some screenshots of what my CPU-Z looks like. Is there anything wrong with it?

I'm not sure how to change RAM timings, this is only what it's showing me on Piriform Speccy. Is there a better way to check/change the timings?

I should also note I've been using this computer without issue for about 7 months.
 
it may not be a hardware issue. a lot of old mb cant run all of windows 8 features. the newer z77 mb needed bios updates. to me it sounds like windows is trying to power down a part of your rig and it locking up. try going into the bios turn off power saving features and do the same in windows power profile. under network devices uncheck let windows turn off deivice to save power also do that for your mouse.

Haven't overclocked anything. Although now that I check the info on the ram I ordered, the info given to me by Piriform Speccy seems to be off/wrong. The Ram I purchased should be at:

1600 MHz (9-9-9-24)

It's G. Skill DDR3 PC3-12800 1600MHz Ripjaw Series (9-9-9-24) Dual Channel kit.

As per the suggestion above I set the timings and the frequency to (9-9-9-24) and 1600 MHz.
For some reason Piriform Speccy still shows that my DRAM Frequency is 796 MHz, even though the timings were set to 9-9-9-24.

updated my bios and made sure the ram timings and frequency were correct.. going to leave my computer on while I head out to lunch, will report back to see if that has fixed the issue.

No luck. Computer froze as usual. downloaded and ran memtest86, which showed that my memory was fine. updated all my drivers from evga, but computer crashed anyway, again in about 45 minutes-1 hour. Will try what smorizio said earlier and turn off power saving options in bios and windows to see if it affects anything.

*EDIT*

Left the computer alone for a while and when I came back, the computer had rebooted by itself and was stuck before booting into WIndows with the message: DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER.

How else can I check my SSD? I've used Crystaldisk Info and SSD-Life and both have said that my SSD were in good (perfect) health. Could this be an issue with my PSU?

By this do you mean turn off ACPI in BIOS?
