Monitor losing signal and random restarts! Help!

Hello,
A few weeks ago my computer (self built, see specs below) started to have some issues (I've the machine since 2 FEB). At completely unpredictable times during startup (after the windows 7 logo) the monitor would lose it's signal and occasionally restart from this point. It would also do this occasionally when bringing the computer out of sleep mode. In addition, once in a while upon waking the computer from sleep the video card fan would spin very very fast. Below I have also listed the attempts I have made to troubleshoot this issue, all of which have been met with no success.

Installed new video drivers. Completely erased all traces of video drivers, removed video card. Reinstalled video card and freshly installed new drivers. Opened the computer case and cleaned it, checked all connections regarding video and power, reseated RAM checked all fans to ensure that they work, no issues found. Finally I wiped my hard drive and did a fresh install. The problem still persists. What else can I do to resolve this issue? Any help that you can provide would be greatly appreciated.

System specs:

Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor

ASUS 24X DVD Burner - Black SATA Model DRW-24B1ST/BLK/B/AS - OEM

Western Digital WD Black WD1002FAEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive

ASUS SABERTOOTH Z77 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL

Seasonic SS-660XP2 ATX 12V/EPS 12V, 660W, 80 PLUS PLATINUM Full Modular certified Active PFC Power Supply

EVGA Nvidia GeForce GTX 660 Superclocked 2GB DDR5, model: 02G-P4-2662-KR

OS: Windows 7 Home Premium x64

If there is any other information you may need in order to assist me please let me know.

Thanks again!

how about BIOS update?

I've been thinking about that, but I've never done it before. I could be wrong, but isn't flashing/updating the BIOS risky? Don't I run the chance of ruining the mother board during that process?

Little update here, I described my problem to a local computer store and they are telling me that it is an issue with my PSU. That doesn't make sense to me...when I get past the problems I've been having (above) I can run graphically intense programs just fine. How is it the PSU...please help, I need to fix this thing before anything else goes wrong with it.

well, BIOS update is not recomended if your system running normally. refer to the motherboard manual on how to update BIOS.
I suggest to turn off sleep/wake up mode. about your PSU, i see no problem, its an 80 plus.

Sorry, never updated. I call to ASUS concluded that the main PCIe x16 slot has a short in it or some other fault. Don't really feel like sending the board back right now. Thanks for all the help, though!
