Alright, this is gonna be kind of hard to explain, but I'll make it quick:
I bought this PC like half a year ago. When I first got it, it had a weird problem with the screen turning on and off, cycling between Analog and Digital for like 15 minutes after being started from a cold boot. Then, after finding out that a lot of fans were disabled in the tower, I worked on enabling some of them. After I did that, the screen the no longer flickered, but apparently, I messed up some of the cooling, because after that, the computer would get like intolerably noisy, like a air-conditioning fan was blowing every time I played a 3d-intense game. So one day my brother came along and looked at it. Apparently, in my attempt to get the other fans working, I had wired them to a weaker power cable or something. That was fixed, as we managed to install two completely new, bigger fans in both the front and the back of the computer -- Now it's absolutely tolerable, even under increased load, but now the screen cycling has returned. It will happen after a cold boot, or after resuming operation after having entered sleep-mode. Once it's gone, restarting the computer, it starts up just fine. It doesn't matter whether the screen is turned on or off.
I wonder if this could be the powersupply just being ****, but before messing with that, I figured I'd see if you guys had had any similar experiences.
Specs:
CPU - I-760
GPU - 480GTX
Motherboard - Gigabyte P55-USB3
RAM - 8 GBs
PSU: 1000W (some cheap brand... yeah, I know)
It's still under warranty I think, so sending it back is always a possibility.
