So I built my dream system Intel 6850, nvidia 8800 gt, 2G Ram, gigabye quad 6 mobo and all was well. Right out of the box I got 3D mark scores of above 14,000 and ran Crysis at very high settings no problem. 6 weeks later I am lucky to score above 5000 on 3Dmark and I don't know why. I have updated drivers, tried increasing GPU clock with gigabyte utility and used ntune. Still no dice. I am a novice when it comes to performance enhancemanet and overclocking so any help would be appreciated. Thanks.
Something has drastically slowed your system, this you already know.
Now the question is what could it be? Now is the time to run a good anti-virus and look for spyware, rootkits and Trojans.
The big question is what have you done with our system since it's first build to cause this slow down to happen?
I run ad-aware, spybot and windows defender also I use sysinternals rootkit revealer along with sophos anti rookkit software.
Last a good fire wall to see what is going out to the internet from your system.
Parn and warze sites drop a lot of crap onto a system, use Firefox as a browser to cut down on that crap.
A full format and reinstall may be the only way to get your speed back.
trojans and virii are a good guess but hows the cpu temps? maybe the cpu heatsink has loosened itself and now its throttling down to avoid overheating. Throttling could cause a major decrease in performance...
Wow, thanks for all the help. I have run ad aware and Spybot and I keep tea timer active. I use the windows firewall( Iknow not the best but ZoneAlarm kept screwing up my DSL connection) I use AVG antivirus and a recent sweep revealed no hits. At idle my CPU is at 0-1%. I don't think the temp is a problem as I run 4 120mm fans in a massive antec case and have never seen anything above 50 degrees. I also have a huge heatsink and fan on the cpu at that rarley gets over 34 degrees! I'll try the other things and get back to you. Any chance the BIOS on my motherboard is causing the problem. Th bus frequecies seem to be OK and it's not locking up, just alot slower than it should be. And yes I promise to stay away from the naughty sites from now on.
Select your OS and follow his instructions to the letter. this will clean out unneeded startup services that are just taking up RAM. Also follow rally's instructions and do several DIFFERENT virus/malware scans and defragment your hard drive.
Edited for miisquote.
aint here to answer you, ( sorry ) im here to tell you that i got the same damn problem and was hopin to find some answers in here hopefully some of these recommendations will work.
What, if anything has changed since the system ran well?
Exactly what components do you have? In particular, the PSU.
Turn on the task manager , then the performance monitor while running your tests.
Is there anything unusual? IE unknown tasks, high ram usage, high cpu usage?
Is the vga card operating at it's proper rate?
Is the psu properly plugged into the vga card? If not, it will not operate at full speed. Is the psu a cheap one that has possibly deteriorated?
