Games crashing to desktop without errors

[Jahobi]

I built this computer a couple months ago and everything went fine and I've had no problems. Then one night I went to go turn on my lamp and bumped some milk straight into the rig like an idiot. The computer was on standby and I cut power immediately and opened the case and dried it out. Next morning it boots fine, and I've had absolutely no issues, except that when I try running more intensive games, (Metro: Last Light, Archeage) the game will randomly freeze and then crash to desktop with no error messages very frequently.

Other games, such as League of Legends and Killing Floor, run fine and don't ever crash. I really don't have much computer knowledge when it comes to this sort of thing so I'm completely lost.I ran memtest with no errors, though when I ran 3D Mark it crashed as it got into the more intense tests with my frames dropping to around 20fps, and I tried running Prime 95 which also stopped running quickly. Any help is appreciated, thanks!

Fire is the devil's best friend and liquids do that to computers or electrical items so... this is what I would do. No, I am not saying it will fix the issue but it won't hurt either.

Unplug everything from the rig, open both sides and make sure you use an air blower through it, making sure you don't point directly to it but more so like you are spray painting a wall. Unseat the video card and do the same to it and to the slot where it was seated. Ditto with the sticks of RAM and any other PCI/PCIe hardware you have connected to the motherboard. If you want to go the extra mile, unhook the CPU, blow it, add new paste and re seat back on but I think this would not be necessary unless you dropped a gallon of milk.

Say your prayers and restart the PC.

Just for good measure, I would uninstall and do a fresh install of the Video and Audio drivers... Again, it wouldn't hurt.

If it had been water it wouldn't have been so bad as it would evaporate eventually, but milk is going to leave some gunk behind. When you take your rig apart as suggested by AstaLaVista take a good look at the areas closest to where the milk went in and see if there's any residue or sticky areas. If there is you could really do with using a light solvent cleaner on a small hard brush to clean it away as it can eat away at any soldered joints.

How hot is your GPU getting? You mentioned 3D Mark crashes on the more intensive tests. It sounds like it could be heat related. Are the fans spinning on the graphics card(s)? There are several tools, like GPU-Z that will show hot it's getting. You may have to pull the card and clean it out. Also, is your computer reporting the correct amount of RAM? (Desktop --> Computer --> Properties). If it isn't, you may have to pull out, clean and re-seat the RAM sticks.

Replied to the Wrong post... sorry!

So I ran 3D Mark again on the Skydiver test. Previously, the CloudGate test had crashed on the physics portion when my frames dropped to around 20fps. However, on this test my frames remained in the triple digits and crashed anyway. Here is the error message I get:

I also ran GPU-Z in the background and here is the max readouts I get from that:

I already previously reseated the graphics card and RAM and it displays the correct amount. I will try re-installing drivers and cleaning it out with air.

Edit: I clearly should also note that the day after the incident my screen did turn into a mess of horizontal pinkish lines and did not resolve until I restarted the PC. While playing games recently I have also noticed parts of the screen will seem to glitch out for a split second as well. About 2 days ago my PC bluescreened on top of that. Sounds like video card?
