I have a strange problem with my pc..
When i turn the power on, (cold boot) the pc boots as normal and windows 7 laods.. but if i start any 3d or video or anything that stress the system, i get a colored screen (sometimes all pink, other times blue, sometimes i get the rainbow colors!!!).
I have to shut down the pc, turn off the PSU switch, then turn the pc on again.. Most of the time this fix the problem (if not i have to turn it off at least one more time).. I can run anything just fine for hours (Folding, games , benchmarks etc..)
If i turn the pc off for some time ( more than 5 minutes), then i have to do the cycle all over again..
I tested the memory and it is fine.. i even changed my PSU and still the same problem. could it be the mobo or is it the GPU? if it is the GPU shouldn't it crash every time?
Any feedback is appreciated
edit: i get smth similar to that
edit: i run memtestG80 to test the GPU and it reported no errors!
