BSOD on brand new computer

Hello. I recently built a new computer and its been running ok. But I'm having a nagging problem I can't quite seem to figure out. Basically, whenever I'm playing GFX intensive games like Crysis II and Starcraft II my computer will randomly lock up, make this really annoying sound almost like a *BZZZZZZZZZZZZZZ* coming from the speakers. Kind of like a really fast looping sound, not sure how else to describe it. Sometimes the game will come back and other times I will get this BSOD error. At first I thought my GFX card was faulty so I bought a brand new one with no avail.

Although this problem is most common while playing high end games, it has happened randomly by just me being on the computer or playing something like WC3 which should just run fine, but for whatever reason...

Windows 7 Professional 64
4 Gigs of RAM

1 Terabyte SATA Harddrive
Intel i5-2300 2.80GHz

I installed Windows 7 myself, so It didn't come pre-installed.

Attached is the stuff you guys asked for. I really hope somebody can help me, because this is a extremely frustrating after spending 1000~ on a computer that shouldn't have ANY problems.

Tricky , I would have thought it to be the gpu as well , but seeing as you have replaced it then it sort of rules it out unless you have been mega unlucky and got 2 bad ones lol.

What PSU you using? And have you got gpuz installed to check your temps on the card?

After doing a little searching around on google for error code STOP 0x00000101 it seems to be either a cpu issue or driver issue for the graphics card.

Have a little dig around yourself , fair bit of info on it.

My power supply is 650 watts, and I use RealTemp. Don't see anything out of the norm.
