Hi, i recently bought the XFX Radeon 7790 1GB Black Edition from scan and ever since i have got it, i have had persistent problems with the card, when installing the card and installing the drivers, after i had finished installing the drivers, they have been crashing often, also when playing games, browsing etc.. my screen flickers white or with lines. I don't know if this is a defect or a problem with the card. Also, my pc would freeze randomly at times.
