Total computer lag/slowdown

For the past few weeks I've had a total computer lag/slowdown. The past two times it was malware related. This time the malware fellas/ladies have helped me to a point where they say it's not malware. I'm not quite sure where to go from here (they sent me to Software/Hardware) :-/

Possibly Pertinent info:

- Windows 7 Professional (64-bit)
- Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz 9.04GHz
- 8.00 GB RAM
- Video Card: EVGA 012-P3-1470-AR GeForce GTX 470 (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
- Mother Board: EVGA P55 FTW SLI 132-LF-E657-KR LGA1156 Intel P55 ATX Intel

 

UPDATE: So I ran TweakNow RegCleaner 2012, and everything works like magic.

Thanks for the assistance, and getting my computer clean!
