Hi there,
First off you will have to excuse me if my technical jargon doesn't jive very well or it doesn't make sense. I will try to do my best to keep it simple so as to not confuse anyone. I understand the basic concepts, but as things become more intricate I tend to lose my understanding.
Ok so I purchased a gaming rig from a reputable (or so I believe) online company that specializes in making gaming computers, low to high end computers.
I personalized a computer adding/upgrading some components I felt that I would like to have in a gaming computer, here are my specs:
Intel I7-2600k 3.4 ghz
16gb Corsair Vengeance 1600mhz DDR3
Gigabyte Z68A D3H-BE
500Gb SATA II 3.0 GB 16MB 7200RPM
XTREMEGEAR 800 watt PSU
EVGA GTX560 TI 1GB
Windows 7 Professional
Here's my issue(s): When I first received my computer all seemed well (except for an LED light was not working for the case appearance only). The company left 6 screws for the case to roll around inside but I didn't think too much of it. I hooked everything up, installed the necessities, updated some drivers and began installing games. At this point I had the computer on for roughly 16hrs. After I had installed the new game (basically the one I purchased the computer for) I started playing. About 20 minutes into the game the computer locks up, the screen showed tons of static and then nothing on the monitor.
I was worried as this computer could more than handle the settings of the game that I had it at. I went to reboot the computer and start running some tests to see what was going on. The monitor showed "NO DVI Input". I checked the connections, everything was fine - except I had the DVI plugged into the mobo instead of the video card? I rebooted once more, same issues. I then decided to switch out the DVI for VGA, same thing, no input.
At this point I was getting very frustrated, I tried the monitor from my other (older) computer, same thing no input via VGA. I then tried to plug the DVI into the video card, no change. I unplugged the power cord, opened up the computer to see if something was fried, everything looked and smelled normal. I took out the video card to take a better look, no issues. I took out the memory x4 (they were extremely warm!) I then reinserted everything and tried booting up the computer, still no input. Now however, the computer is turning on for 30sec then turning off, this is on going.
Finally I took apart the CPU water cooling fan and took a look at the CPU, I am not experienced in this area but I saw no issues with the CPU.. The thermal paste looked a little skimpy, but I am not sure if that is normal?
That was all last night, needless to say I didn't get to play my game. Today I took my PSU down to a very good computer/tech shop and they diagnosed the PSU to be faulty and not working. I thought "great! I'll just buy a new PSU (as I also found out the xtremegear are total pieces of junk anyways!). I bought a Thermaltake 850w TR2 RX and installed it into the computer and attached all the cables (first time doing that). I thought for sure this would fix the issue and I could start back to normality. I was wrong, still same issues except the computer turns on for 15sec and then shuts off only to start back up again and repeat.
I appologise for such a lengthy post, but I figured the more info the better to help find an answer.
Any help would be greatly appreciated!!
Chris
