Weird fps drops/Overclocking doesn't help?

[SpiritBob]

Hey, I've been trying to solve this myself but as i can see it's just out of my league...
Today i went to my friends house and he had an AMD Athlon 7800 Black edition 2.7ghz CPU and a video card Nvidia 9600 GT (512mb). We started playing MOH (medal of honor)
and i was stunned, it was running on 50-60 fps and rarely going below 50 fps.
My computer is more faster than his one (The details for my hardware are in the Dxdiag file i attached to this post) and yet I'm running it on some shitty 30-45 fps...... whenever i look in a directions where there is action (doesn't matter if i see the action or if i am behind a wall) it's just dropping.....and if i see a smoke grenade the fps drops dramatically! Also I'm on medium settings and my max screen resolution is 1440x900 (the monitor's Model: Philips 190CW),as for my friend he had max resolution 1600x1050 and he was playing on THAT resolution with such high fps on medium settings of the game ( I'm playing it on medium too). I tried to play it on low but there is barely no effect at all O.o I'm experiencing such fps drops in MANY other games.... it's really strange.Tried overclocking... nothing works it even gets worse i think :eek: (Tried with raising the CPU Voltage,still no effect.) :(
I hope you can understand this weird problem of mine.

Hi,

If you haven't already, check your hard drive to see if it is fragmented. If it is, do a disk defrag to clean it up some. Lag can be caused by the hard drive having to seek and retrieve data it needs and drive fragmentation can cause the seek time to go up. Also, turn off any extra services that may be running in the background that you do not need, such as adobe and quicktime, ipod service, etc as they take up resources. I also use a program called ccleaner to get rid of junk files on my hard drive and it also has a feature that cleans up your registry as well (just be sure to make a registry backup before you let it fix the registry just in case). Also, I see you are using hardware accelleration for the sound according to the dxdiag.txt file. I have found for some reason in certain games, that can cause lag. It happened really bad for me in ghost recon, it would freeze when firing the guns. Once I turned sound /audio hardware accelleration in the game off, the lag disappeared. If that doesnt help, maybe try an older graphics driver for your video card. Sometimes the newest drivers are not always the best working ones. If a different driver doesnt solve the issue, see if your friend will let you try his card to rule out the video card as being what is causing the lag for you.
