So, let's figure this problem out.
Here's my situation and my hypotheses as to what it is.
Within the past week or so, my computer has been experiencing spontaneous freezes after a few minutes after using software that makes use of my GPU or anything graphically intensive, specifically games and once during a video. After this freeze of 20-60 seconds, the screen will usually, but not always flicker off then back on. Again, sometimes, after the flicker, the display will be messed up and displaced. It seems as if the monitor is divided into tiles and some of the tiles are in the wrong places, making the display nearly impossible to see clearly. I have not been able to get this to go away without a restart. I don't know what it is.
Here's what I think might be to blame.
Gateway has my PC equipped with a 300W power supply. It was faulty and they sent me a new one for free, another 300W, but a slightly different model. The problem did not occur before installing the new power supply, and began only a week or two afterwards. I'm thinking that the power supply is not giving the GPU enough power and sometimes it will cause a freeze up and then when it regains equilibrium the picture screws up. This is just my interpretation, and I hope somebody will be able to give me some feedback and probably figure out the real problem. I'm just guessing 300W is not enough, even though that's all Gateway would give me.
Also: if my computer isn't getting enough power, is it damaging to the parts?
I hope we can figure this out. Thanks ahead of time.
Edit: It happened again, and this time it just caused a restart after a minute long freeze/blackout. This is getting urgent. :(
