My Geforce graphics card fan started running rough and now barely runs at all, causing it to overheat. I can't afford to replace the graphics card at this time so I was hoping I'd be able to clean it and get it running again. I've tried blowing it out but the dirt seems sticky. Is it a loss cause? Am I going to be forced to get a new graphics card? I'm kind of computer dumb so may need a lot of help, lol.
