New PC, GTX 770, GPU fail? Bitminer? Games don't work

Recommended Posts

Hello everyone, I just registered, nice community you have here :) I have a big problem and I'm not sure if it's a malware (bitminer-like) or not. I'm not sure if this is the right part of the forum, but here we go:


I built a PC for the first time 2-3 weeks ago, a gaming win7&hackintosh dual boot system as I needed OS X for studio programs. Here are its specs:


Intel Core i7 Haswell 4770k 3.5 ghz 

Asus GTX 770 DirectCU II OC 2Gb graphics card

Gigabyte Z87N-Wifi motherboard

Corsair Vengeance 8x2 Gb 1866 mhz RAM

Seagate Barracuda 7200 RPM 3TB 64mb cache (as Windows 7 Professional boot disk)

Samsung 840 Pro 128 SSD (as OSX Mountain Lion 10.8.5 boot disk)


I put effort into this as this was my first time building a PC, let alone succesfully dual boot it, but I managed to do it with disabling internal graphics (HD 4600) in order to run both systems without removing-plugging GPU over and over (OS X wouldn't boot otherwise). My computer case has not arrived unfortunately (beware of low-rated amazon sellers), and I was hyped about the PC and been running it by placing the motherboard on the box it came with and all components on the motherboard on the air, maybe this was my mistake to start with. However I ran it with no problems and great performance on everything including games up until yesterday for like 1-2 weeks straight. What happened was; after a long night of gaming (Borderlands 2), I quit the game for something and when I launched it again some minutes later, after all the yada yada logos (2k, nvidia, etc.) when the game's main menu was supposed to launch, the game minimized and system got into some kind of a freeze (not entirely, because I kind of heard game sounds and I was able to ctrl+alt+del and kill Borderlands 2 which un-freezed it). But after that moment forth, whenever I tried to launch into a game that is graphically even a bit demanding, it kept doing the same thing: when a graphically demanding part came up in a game (for example when the borderlands 2's menu came up, because it contains in-game graphics as a background of the menu), it minimized and froze, and wouldn't alt+tab into the game again. GTA IV went in the menu ok, loading part was fine, but when I got to the point where the game was supposed to start, it got minimized, etc. I looked at the Asus GPU Tweak software that came with my GPU, and it's weird that when this minimizing-not working the games thing happens, it seems to spike up both the clock speed and VRAM memory to the absolute max, while the temperatures of the GPU are fairly normal (such as 30c). When I kill the game from task manager, every off the chart reading goes back to normal again. What could be my problem? Oh and the most important thing that scared me was when I was on facebook and looking at some pictures, you know when you click a picture and it opens like a pop-up, blackening the background? At that black part, I saw some white pixels. They were very few and scattered along the black background, but they seemed to change places as I moved my mouse against that black background. Oh and I tried reinstalling the graphics driver, and I'm not sure if I remember it right on my first try after the problem occurred it went fine, but other times at some point during the installation the screen went black and I had to reset to get any display again.


I will try installing windows on another hdd along with a game and the graphics drivers, and try if this happens again, in case maybe it is some sort of a new unknown bitminer (I suspect it might be). But should I be putting this heavy GPU on my mini itx motherboard's pci-express slot while it has no other physical support that holds it but the slot itself? Could it be that my mobo's slot or the GPU may be damaged? I am very concerned and fear that it might be the case. However at the same time, I'm relieving myself by thinking that if the GPU failed, it would fail completely and I wouldn't get any display from it (I mean, I'm using the PC in 144 hz mode and without the GPU that's impossible). What should I do? Thanks so much for reading, I know this is not exactly the type of forum for technical PC support but I think this might be concerned with a malware (a possibility). I hope somebody is able to help me :) Thanks again in advance.

Hi and thanks for your fast reply :) I attached the two files you requested. However, note that I do not have the GPU currently installed on the mobo, because I was scared of any damage to GPU or mobo, or both after I saw the white pixellation. All of this may be physically caused by me because I didn't use a case, and the heavy GPU rested only on the PCI-E slot I'm afraid... :/

Okay, well there are so many errors Event Logs that it's hard to know where to start.  Let's go ahead though and have you run the following and we'll start with this.
