I am having an issue with my computer at the moment, i Overclocked my i7 870 to 4.2 ghz, was running stable for 1 week. Then decided to tone it down as i was not hardcore gamming at the time. I am having a problem with my GTX 480 I THINK. Before i overclocked my graphics card from default to around 100mhz more. I noticed no change in graphics quality or performance. I did notice that my Benchmark with Mark3D before i overclocked it was running at around 55 - 60 FPS with all things running in the extreme benchmark test. When i "overclocked" the card EVER so slightly. it didnt really do anything, I changed the settings back to default and now i can currently getting >....12 FPS ... THATS RIGHT 12 FPS in xtreme Benchmark!, i have no idea why this is happening, my GPU temp never went about 70 degrees. if it did, i turned the benchmark off. and rested it. My CPU temp also doesnt go above 35 degress. Any suggestions how i can tell if there is someone wrong with my graphics card or other issues??
