I then (trying to see through the lines) flashed the original bios back to it which restored it back to the way I received it. Using nvflash, I flashed the bios made for the 3GB card (bad idea), the card posted and went into windows but the screen was full of artifacts and lines and drivers still didn't load. However in GPU-Z it says there is 3GB of ram on the card, not 2GB. One of the stickers has the bios version of the card and by looking that version up it says it's the GTX 660 SC 2GB card (as i figured when I bought it). However there are stickers on the heatsink casing. There are no stickers on the pcb board to help with identifying the card. ![]() I've Installed each driver in safe mode which puts my computer into an infinite boot loop where it restarts then the graphics driver is being loaded. When the graphics driver is installing the screen goes black and the computer restarts. I tried to install every driver from 344.48 to 350.12 (Latest). It loads everything, it will boot into windows without safe mode and I can do anything as long as it is not graphically intense. I have performed multiple repairs to dozens of cards in the past but this on has me stumped. I have spent 11 hours researching and trying different remedies in hopes of figure out whats wrong with this card. I purchased an EVGA GTX 660 off of ebay (non working) and just received it this morning at 8am. ![]() ![]() First off, I hope I'm in the right area for this since it's my first post.
