I volt modded my 7900 gt a while agoe using all 3 of the solder mods, totalling 1.55 v i believe. I then snapped the 3rd bit of solder off of the board by accident. This lowered my potential overclock to about 645. Today i tried to re solder the 3rd connection but it just wasnt having it, and i retried a few times. Now when i load windows, the bios looks perfect as does the windows loading screen, but once it goes to the sign on screen (blue) shapes appear and do not move. Around 2 mins later the comp restarts. I wanna hock this card to a friend as part of a build, but i need it to run fine at stock speeds in order to do so. Any help?
