Thanks to Black Friday, I managed to put together a system, but recently I've found that my computer just suddenly loses display. I had this problem a while back with my old system, thought PSU wasn't enough and turns out I was right. It mostly happens right when I open either a YouTube video or start a game. Last time I had this display problem it happened during Windows Index Rating and when I looked at certain areas in games (I'd assume the more "intense" areas). Before I had a computer with a stronger PSU available, now I do not. So I have no way of testing if it indeed is the power supply. It would be much appreciated if someone could tell me why I'm just suddenly losing display.
(I wish I could give more on the problem, can't connect to my computer or re-establish the display without restarting)
And the case (Corsair 550D - www.newegg.com/Product/Product.aspx?Item=N82E1681113901...) comes with 3 fans and I'm currently using two of them (I got a connector to give power to the third one, but after that this problem started happening, I unplugged the third one but I still experience the display crashes just as frequent).
If this is true than there would be 2 things I would consider possible issues.
* Mobo is flaky and not working right (not stable, especially after adding in case fan)
* GPU is flaky and this is why you have the same issue from previous build, if I understood this correctly.
You might want to run Memtest86 on your RAM sticks and verify that they don't have any issues. Also if you can get Prime95 to run, then I would run it for at least a few hours to see if you have any other issues.
It's also possible that your PSU isn't doing its job, but its unlikely the case since it's a new PSU and is of pretty good quality. This doesn't mean that it's 100% signed off as a good part, but it's something to keep on the list of possible bad parts.
