Hi people, Long time lurker first time poster. I've read the website a lot over the last year or two, hoping I would never need to register and ask a question however, that time has come I have a i5 2500k at 4ghz, Biostar TP67B+REV3, Gigabyte GTX670 (2GB), Coolermaster 650watt PSU. When gaming, especially on Bioshock infinite, after 5-10 minutes I have the following issues - http://steamcommunity.com/sharedfiles/filedetails/?id=149697888 after some 10 minutes of playing. I have installed MSI afterburner and altered the fan settings (nothing else) to come on earlier at around 60 celsius, 100% fan speed, however, it keeps happening. Driver version is currently 320.14 but does the same on 320.18 also. Is my GPU kaput? If I have missed anything you need to know please reply and i'll advise you accordingly.
