Hello everyone. I've been reading this forums for a while, whenever I've a problem that I do not know about I come here to check, this is a great service you're all doing. But now it's my turn to tell a story, I can't figure this on my own. My PC specs are on the sig, any additional questions just feel free to ask. I practically bought this computer by parts, taking my old boards and cards out of the case. I know my share on hardware, specially electrical stuff. Problem: The Computer started to freeze and crash in BF2 with a multi-colored screen bars everywhere, it would just crash the game and come to desktop. I thought it was because I was testing the limits of my graphics, started to go on ease on it and it was fine. Not more than a week ago my computer started do the same thing in any kind of game. I thoguht it would only do that on heavy graphical games but started to do that on low graphic ones too, yesterday the frequency of doing that was high enough not to open any game, specially because this time the whole computer would freeze on multi-colored screen, and even more weird, the sound would start looping, so gfx and sound freeze, also freezing my controls (mouse and kb), which led to manual reboots. After testing alot from any forum I would find, even through this forum, I couldn't find any solution. Today I've unplugged everything and plugged everything back, the problem still exists but now it doesn't even freeze, just power crashes the computer, which makes me think this cannot be a software problem. This is what I know: This is not a overheating problem, I installed a new fan under my gfx card because my old one was doing some noise and stopping sometimes, I was afraid the overheating would have led the gfx card or sound card (in each side of this fan) to melt or burn something, but they're fine. I've ran CPU+RAM stress tests, graphic stress tests and reinstalled gfx driver and dx 9.0c (same config as I ever had). For crashing both gfx and sound, I thought it was maybe the power supply, I've opened it and there's nothing melted or burnt, there could still be an over-power problem causing short-circuit, which I doubt it's happening or else it would crash without games. Also maybe the CPU, which is always mysterious, besides cleaning, is there anything I should look for signs of CPU malfunction? My biggest guess is that my Corsair RAM cards are malfunctioning, would explain why low graphics games would crash after a while, and why games using heavy single player bots would crash not even a minute after starting the game, but doesn't explain how now it power crashes the whole computer, does it? Could always be my ASRock motherboard, which never gave me reasons of problems, so I've no idea how this problem could be related to it. I've read somewhere about leaking capacitors, but I don't see anything wrong anywhere. There were a series of power cuts in my town in the last months, I've checked everything and there's no signs those power cuts affected the computer, but who knows? Any tip? Anyway I can figure where this problem is coming?
