Hi, I have a following problem
A couple of days ago I was playing a game called A.V.A and suddenly the sceen turned into black. I tried switching the monitor(display) on/off, but it did not help. I even tried restaring the computer several times, although the computer itself turned on normally there were still no image(picture). After reconnecting monitor power cord my computer worked fine again.
After that incident two days later when I was chatting on Windows Live Messenger suddenly green and purple horizontal lines appeared on screen plus some elements from my destktop wallpaper had a red dotted edges. Then I also tried switching the display on and off, but it did not help. Those graphic artifacts were there about five minutes and then they suddenly disappeared.
Graphics card temperature at idle is 48C and at full-load maximum temperature is 93C. I have cleaned computer regularly after every 3 months and those temperatures have been like that since I bought that graphics card.
What is causing this problem? GPU or monitor/display? I hope someone could give me advice.
