Low FPS

Specs:
Pent 4 3.0ghz
1gb ram
7950GT BFG
Vista Basic

I play BF2142, CSS, CS 1.6.

I get about 10-30fps bf2142 on med graphics online, css I get around 20-60, and 1.6 30-60. I dont understand how I can be dropping down to 30fps in 1.6?? but I can run css and bf2142 on my computer?? My friends tell me I get unusually low fps because my system is better then theirs and they still get much better fps around 80 on source. I am losing performance somewhere badly, I think it might be my os I have no clue.

Does the task manager not show all the processes running in the background? I removed sidebar, and when I game I only got 7-10 processes running

(nvm about 47)
Is 48 alot of processes to have running at once?

bf2142 needs 2gs min. But u should still get better frame rates...interesting? Try playing with xp without sp2. U should have a frame rates of around 200 for cs at lest. Bf2142 im guessing around 100. Or maybe try diff vidcard. Just try differtn cominations until u find the prob. This is the fun part about computing...enjoy it.
