Two years ago I bought a new Asus socket 775 mobo. I installed everything nice and fresh but the desktop would flicker. The flickering would get really bad if the cpu is handling many jobs. However, watching movies full screen is ok. A while after that (i think i must have done a clean reinstall) the flickering disappeared and it worked fine for about a year. Now I just installed a new power supply unit after the old one died and the problem is back! It is really frustrating when I’m trying to do some work and I get all this flickering. Is the onboard video faulty or is it something to do with power? I would really appreciate some feedback if someone out there has a few minutes to spare.
