I have a really serious problem with my computer and I beliebe it has something to do with my graphic card. I had it running for about 5 months now with no problems at all. I didn't really use it to it's maximum capacity, since I didn't play very graphic intense games, World of Warships being the most graphic consuming game I played during that time. I did no OC or anything to it or anything. Since my graphic card is the newest component of my system, I am really irritated about the problem I have now. Here is a brief overview of my system:
CPU: Intel Core i5 750 2.66GHz 4800MT/s S1156 95W 8MB BOX
CPU fan: Scythe SCMG-2100 Mugen 2 REV B.
Graphics: 2048MB MSI Radeon R9 270X Gaming 2G Aktiv PCIe 3.0 x16
RAM: 2x2048MB Kit G.Skill Ripjaws PC3-10600 1333MHz CL7
Power supply: ATX be quiet! Pure Power BQT L7 530W ATX 2.3
Case: Midi Antec Nine Hundred Gamer (ohne Netzteil)
Mainboard: GIGABYTE GA-P55A-UD3 P55 S1156 ATX
Primary SSD: Samsung MZ-7PC128B/WW 128GB SSD
Operating system: Windows 7 Professional 64-Bit
I have two 24" Monitors connected to the graphic card, one being connected via DVI and the other one via DisplayPort.
When I start my computer I get a black screen after Windows is fully loaded. The boot sequence and everything works just fine. I also see the Windows logo and the "loading animation" right before I usually log into my Windows account. But then I get this black screen. I can start Windows in safe mode however.
The problem didn't occur out of the blue. It "announced" itself through some earlier troubles two days before. The first occurrence was during a game when the screen turned white, with some gray vertical lines in it. After a short time the computer shut down and restarted itself.
When I restarted the computer, everything worked just fine. After some time this happened again. Now the problem got worse. After logging into my Windows account I only got a short view on my desktop, before the screen turned white again. I figured that this might be a problem with the DisplayPort, so I disconnected the Monitor that was connected via DP and restarted the computer. Now it worked again, but when I started World of Warships, the screen turned white again. Since I updated my display driver some days before the problem occurred, I decided to try and install an older driver version, namely the version supplied with the CD that came with the graphic card. When I uninstalled the graphic driver and first restarted the computer, both screens worked just fine, but they both showed the same content of course, since there was no display driver installed. When I installed the older display driver version, the problem occurred again, the screen turned white right after I logged into Windows. Now I uninstalled the old driver again and installed the new one and I got the problem as it is now, the screen turns black after Windows loads and the computer shuts down after some time.
During all this, I also checked the windows error log for issues concerning driver conflicts, but everything seems to be fine.
All this leads me to the conclusion that there is something wrong with my graphic card. I first thought it was only some driver issue or there was something wrong with the DisplayPort, but it seems that the problem is much worse and there is some hardware problem. Does anyone have a similar problem? Do you have some ideas to conclusively clarify if it is a hardware problem? I think I should turn it in so it can be fixed, but I just want to make sure, that this can't be fixed any other way. There is still a small hope, that this is only a software problem.
