Hey im having this frame rate problem recently
where normally it doensn't occur until the last few days.

The symptoms are tremendous drop in framerate in many games
ex. RE5 a couple of month ago i becnhmark it and acheive 60-75 FPS not bad..
on max setting with AA + blur

but now with the same setting it drop to around 20-35 badd..

surprisingly this problem also occur in crysis warhead
where i use to be able to run it on max setting with no stuttering , lagging
or delaying (only alittle bit in some epic boss fight) but now fps drop to 15-30
since the start of the game when only 1-2 enemies appear.

In l4d2 with vsync turn off and multi redering off aswell i only get about 40-70 FPS
which is strange .. i think.. as it should be much higher according to my spec

not all of my game have this issues but most have. :??: 

here's my spec:

CPU: intel core i5 2.67
GPU: Ati 4890
Ram: 4 GB
Window: vista 32
fan olympia 700W

i have no idea what's the problem but im suspicious that the problem is burried deep.

i dont know if this is normal but.. my physical memory is at 40 percent all the time even i didn't run anything atall but maybe its vista well...

here's some things i already tried

upgrade driver to 9.11 newest!

install lastet directX

tweak some option in ATi catalyst turning off AA , etc...
(which seem to bring the fps up abit)

some one suggest that i should reinstall my window oh and metion something about the voltage but im not pro at this so.. :( 

any idea or suggestion would be good. i would appreciate it. im not so good at this kind of thing i usually play them not fix them.. i certainly need help

Thks in advance :D 

(sry for teh bad EnglisH) ;)
