This is the weirdest problem I have ever seen. I am fairly up to date with all the computer hardware, so I find it a bit strange I dont have a solution for this. Every know and then my screen goes black for about 2 seconds, then it will flick back on, and my mouse will be gone ( the cursor ) This will repeat untill I manually reboot. It just very quickly fades in and out. What makes it so hard to figure out is that it happens at complete random. No pattern. Sometimes it wont happen for days, othertimes it will happen when I just get into Windows I originally thought it was heat, although I am using the 'recomended thermal solution from INTEL' Then I thought it was a AGP power issue. So I put in my old Geforce3 It sill happened. I tried flooding the memory, and that made no difference. Any idea's?
