hi guys , i have a really weird problem
a few days ago i bought a new nvidia gtx 650 oc edition . when i installed the card my computer would boot but my usb mouse would not work , i got an error in my device manager as code 43 on the gpu and a standard openHCD usb host controller error , drivers not loaded .
previous to this i had a 9800gt green edition and i had my cpu overclocked to 3.52 Ghz.
i managed to get my mouse and usb problem to go away by turning on cool&quiet in my bios as well as removing my overclock .
i thought it was a power supply issue so i have bought a new one , an ocz 700 mxsp .
things i have also tried were , uninstall my graphics drivers - then run ccleaner , rebooted run again , install latest drivers using a clean install method .
i have re-applied thermal paste to my cpu and north bridge ,re-seated all my memory and connectors.
my specs are
mobo Gigabyte GA-M57SLI-S4 (rev. 2.0) with latest bios
amd phenom II x2 550 Black edition
Palit gtx 650 oc edition
6GB corsair xms 2 ddr2 memory
ocz 700 mxsp power supply
windows 7 64 bit ultimate with sp1
samsung f3 1TB hdd
now before i put the new card in i could run at 3.52 Ghz no problem , but now i have to use stock speed so any help you guys can give would be much appreciated
