Help and Tips: Games lagging on a high-end computer


About a few days ago, my girlfriend and I started playing a game called Dungeon Defenders. It is a 3D cartoon-ish Tower Defense game. It requires a very low-end computer to run, whereas my girlfriend's computer has the following specs (below is what I know off the top of my head, will update once she's awake):


Windows 7 64bit
Toshiba 1.5TB 7,200 RPM HDD
GTX 770
i7 4790k
DDR3 8Gbs
GigaByte Z97-HD3


The game ran fine the first few days (and she has other games that are high-end, Guild Wars 2, Aion, and so on). A couple days later, the game started lagging midgame, and eventually crashing or causing blue screen of death (BSOD). I asked her to try Guild Wars 2, and make sure it runs fine, but Guild Wars 2 runs fine for a moment, and then starts lagging shortly after. Soon after, she started getting the infamous "Display driver stopped responding and has recovered" error.

She is not a very techy person, so I have been helping or guiding her since then using TeamViewer, and other programs. I first tried to reinstall the game, but that did not help. Then I tried to update or reinstall the graphics card driver multiple times (using different methods). I also had Kaspersky do a full system virus scan, and it found many viruses. I checked the GPU's temperature, and it was 42C which is nothing harmful. The issue continued to persist.

Today, I restored her computer to an image I created, using Norton Ghost, on Day 1 of Windows installation, where only the drivers and the main programs were installed (Chrome, Office, Photoshop, and not much else). Note that this image only overwrites the C drive, and not the D drive (the HDD is partitioned). The D drive is used for her personal files (music, photos, movies, etc).

She installed Dungeon Defenders after the image, and she still has the same issue. She tried Devil May Cry on PC, and she had problems with that game as well. She got the same error she previously had, and so I tried to update her video card driver. I asked her if her case is dirty, and she said there is some dust, but not really much. She will clean it soon (in a day or two). Nothing has worked so far. She has only had this computer for 10 months.

Does anyone have any other suggestions? I have not had such an issue before, and I have been trying to help her fix it over the past couple days, but unfortunately no luck so far.

I would really appreciate any help or suggestions.

Thanks a lot in advance.

If the virus is located on D it will create the same problem as before after a bit. Run kaspersky again on whole system and malwarebytes antimalware to see if it finds infection again.

Okay, before I go too far, I want some environmental variables.
1. What Power Supply (Brand, model)?
2. Ambient temps of the area, and your room conditions?
3. Did you run memtest? (Testing memory obviously).
4. Run GPU stresstest like Furmark. (Testing graphics).
5. Run Prime95. (Overall CPU and motherboard related isolation tests).

I suspect a faulty video card, maybe swap with something else and test.
Or maybe no dust maintainance is done?
