i recently built a new computer and i have noticed extremely inconsistent performance, such as playing team fortress 2 at 200 fps one day then either several hours later or the next day trying to play it and getting 10 frames per second. one day when it was particularly slow, i ran 3dmark to try to find out where the problem was, and sm 3.0 scored very low, i think it was around 500 where it normally over 6500.
i am confident my processor and videocard are not having heat issues because i monitor their heat, the processor with real temp and the videocard with ATI's CCC. i'm pretty sure sm 3.0 is videocard related so im pretty sure its not some spyware or windows program thats taking up computing power. the only things i can think it possibly might be would be the motherboard overheating or the psu struggling. but i think a struggling psu is a long shot because i havent had any random reboots. anyone have any ideas what could be causing the problem? or how to test if one of the possible problems i listed could be tested without an extra psu or mobo? i've also taken my computer apart and then back together once, the issue happened before and afterwards, so i doubt its a loose connection.
my computer specs.
i have gigabyte ep35 ds3l, a hd 4870, a 37200 (overclocked to 3.0Ghz), 4 gigs of ddr2 800 ram, 32 bit xp, antec earthwatts 500W psu.
