after many considerations, i concluded that ur pc is possessed.. throw it away or exorcise it.. juz kidding.. mayb the source of the problem is not from ur pc.. try to plug it into another power outlet.. the click u mentioned is it like mechanically sound? the power led didnt light?

try and google ati hd4770.. i heard it outperform 9800gtx+ marginally and cost much less.. why 320GB? juz go for 500GB or more..

ur gfx card surely bottleneck the whole system if u play latest games such as crysis on high reso.. everything else seems ok.. if u upgrade the gfx, make sure to also upgrade the power supply..

got same fps and 3dmark06 score in 1024x and 1440x.. around 9500+.. pretty lame..

must mean the cpu is bottlenecking.. got to upgrade fast..

At higher resolutions, most games become more or less gpu reliant anyway. What res are you playing at?TerroRizing

I play at 1440 x 900..

i am currently using amd x2 4400 with 8800gt 512mb..

i think my cpu is bottlenecking my gc alot, especially in 3dmark06 and some games.. so thinking of upgrading to amd x2 6000.. but how much better is 6000 compare to 4400? will it still bottleneck?
