I ordered my pc from Scan in the summer and everything has been great until now. Today I started getting artifacts whilst playing WoW of all games. Went back to the desktop and that was covered with artifacts to the point it was unusable. I switched off the comp and waited for a while - back on it went and was fine for a short while before artifacts appeared. I reseated the card and power to give it another go and rolled back my drivers. I then gave Crysis Warhead a go and it was fine for a good 5-10 minutes until it decided to artifact to the point where I had to reboot, and now it's artifacting all the time.
I'm planning on giving Scan a ring and making a 2 hour drive to attempt to get this sorted same day or at least in as little time possible, will this be possible? What do I need to take with me?
