Custom built laptop stutering?

[zaknifein]

Hello, I have had my custom built iBuyPower laptop for half a year now, and this is the first time I've encountered the problem. It stutters mostly when I'm playing games such as League of Legends or Skyrim, but I've been playing these games and many others for months without problems. Occasionally it will even stutter when I'm doing simple things such as surfing the web.

I've run a few different registry fixes, such as CCleaner and Tune-Up. I've also run disk checks, and I've defragmented my computer. I've reseated my RAM and harddisks, and my GPU/processor temperatures are nothing unusual. DxDiag reports everything to be fine too... So I'm stuck in a ditch here...

System specs:
Win7
8GB DDR3 1333
Seagate 500GB HDD
Nvidia Geforce GT 540M 1GB
Intel i7 2720 QM 2.20 GHz


Please provide all and any input. thank you!

Wow, lame.... Uhhh fudge then I guess I'll just have to format. I do believe the problem is my GPU however, I tried watching a movie and it was effing up...
