CPU: Intel Core i5-760 (Overclocked to 3.8Ghz 19x200 on stock voltage) + Noctua nh-d14 MOBO: Asus Sabertooth i55 MEM: Kingston Hyper X Black Edition DDR3-1600 ( 4x 2GB ) GPU: MSI GTX 470 Twin Frozr (SLI) PSU: Cooler Master 850W Silent Pro M

I've had this system for about 3 Years now. And I've always had the occasional black screen. (then rarely) Thought it were just Geforce driver blurps but they've been getting a lot more frequent lately with now having scrambled boot screens before turning to black. This can leave me trying to boot the PC for 15 minutes before finally getting into windows and then running stable.

I've had this with my system overclocked or not, with SLI, one card or switched with the other. Correct drivers installed, newest Bios, all in order. So I can be sure that the CPU nor GPUs are not to blame. (Phew!)
My USB ports will also randomly drop connection if I have a lot of USB devices in there (even when set behind a powered USB hub ). Back in the day I could even trigger this by doing something like color picking in Autodesk Mudbox. Or back when I was doing 3D Surround this would happen all the time. Back then I almost sent the PSU back but I ended up not doing it, cuz I actually REALLY need my PC for work.
And I've recently noticed that sometimes 1/4 leds on my fans starts blinking (connected to the motherboard). At times like this I really wish I worked in a computer hardware store so that I could test these things out. :/
So what do you guys think ? Faulty MOBO or Faulty PSU ? Any help is duly appreciated.
