Newly Built PC - Blue Screen Error Hep!

[Digitalstealth]

Hello guys, long time reader, new user. I just recently built my 3rd custom budget gaming rig.

Everything runs great, all games and applications run flawlessly.

Except for 1 little thing. When i leave the computer on for more than 2 hours in the desktop and i go away for a few hours or so, I come back looking at a blue screen error displaying.

**** STOP: 0x000000F4 (0x0000000000000003, 0xFFFFFA8009728B30, 0xFFFFFA8009728E10, 0xFFFFF80002FE3510)

After "googling" and reading the forums for help, I found nothing that could solve this issue.

Some people mentioned that changing the PSU, Using 1 Ram Stick, Updating all BIOS and Other Drivers will fix this issue. It didnt,

I also tried using different versions of windows 7.

Nothing seems to work. Im really stressing out. Do you guys have any suggestions?

Side note: I feel that for a newly built computer, the desktop seems to be little slow at times. It freezes occasionally for a little bit when pressing the start button or opening up programs.

I ran the Windows Experience Index and everything looked perfect.

Processor Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz: 7.6
Memory (RAM) 8.00 GB: 7.9
Graphics NVIDIA GeForce GTX 660 Ti: 7.9
Gaming graphics 4095 MB Total available graphics memory: 7.9
Primary hard disk 510GB Free (698GB Total): 5.9



Here are my specs:

- Intel Core i5 3570K 3.4GHz LGA 1155 Processor
- Biostar TZ77A LGA 1155 Z77 ATX Intel Motherboard
- Gigabyte NVIDIA GeForce GTX 660 Ti
- Thermaltake TR2 Series 500 Watt ATX Power Supply
- Crucial Ballistix Sport 8GB DDR3-1600 (PC3-12800) CL9 Dual Channel Desktop - Memory Kit (Two 4GB Memory Modules)

I am running on Genuine Windows 7 Ultimate and nothing has been overclocked. And I am using the stock fan for the CPU.

I do know that BSOD containing "STOP" is a hardware related issue. My first guess would be the Video card.. Do you have another card you can try?

...just to add...

When I first installed Windows 7x64 every so often I would get a BSOD. I could not for the life of me figure out what was wrong. It was just sporadic, however someone mentioned memtest which I ran and it confirmed that I indeed had bad memory.

You may want to try that, let the app run overnight.

Please note that I cannot confirm if it was a STOP error at the time.
