My friend was having gaming problems on his PC where he would play a game and get stutters every now and then on low resolutions and low graphics, sometimes unplayable stutters, it happened on Need for Speed Underground, Crysis and Call of Duty Modern Warfare and we could figure out a problem so I recommend we upgrade his Vista OS to Windows 7. I upgraded it yesterday but now when we run games the stutter is still there or even worse. I don't think this problem is from the graphics drivers as he has tried a few and now he is running the latest Nvidia firmware, 195 i think.
I think there is something really wrong with his CPU because we ran the WEI and everything was fine except for a CPU score of 1.9, his processor is an Intel Core 2 Duo E4600 at 2.4GHz. His old score on vista was not that low, I think it was in the high 4's or low 5's, I'm not too sure. We ran the assessment a few times and it still gave the same result, we weren't running any programs in the background while doing that. His graphic card is an Asus Geforce 8600GT and motherboard is an Asus P5KC.
I was thinking maybe his processor was a little damaged, that could throw his scores off and give him stutters during a game right? He hasn't tried overclocking at all. Maybe these two problems are unrelated, can anyone recommend some tests for me to try to see if I cant isolate the problem? I wasn't sure where to put this post, I hope its in the right place?
