So Windows bugged me for a little while about getting Service Pack 1, and so when i had time, i let it install the SP. Bet ever since i let it install the SP, my computer just doesnt perform the way it use to. Originally, the CPU usage would not go below 100%. I restarted 2 times and still wouldnt go below 70% CPU usage. I decided to run a virus scan, which turned up some things that have given me problems in the past, so i let it remove them. My computer seemed fine for a day or two, then i noticed the Aero animation when minimizing, maximizing, opening, and closing windows just wasnt smooth as it usually was. So i let AdAware do a full system scan and it found and removed some stuff, but still, the animations arent smooth, games dont run well at all (they normally get max fps on this computer), and the weird thing is, cpu usage is back to normal... So i have absolutely no idea what is going on, so what do you guys think i should do??
Here are my specs if they help:
Windows 7 Home Premium 64 Bit (obviously now with SP 1)
Dual Core Intel Processor @ 2.1Ghz and 64 Bit.
4Gb Ram
64Mb VRAM (not much but this is a laptop, so i borrows from regular RAM and thus behaves like much more VRAM)
Just a side note, i feel as if i am always asking you guys for help, but i never return any. I just cant seem to find any place where i would be helpful, so please forgive me!!
