Strange problems, textures screwed up and blood is TF2, game shuts down without error or notificatio

[LVL FACTORY]

So, i have a few problems with the game, some appeared after i upgraded the computer, some before that. I have pictures for some which can be pictured. The first and the most major is that the game mysteriously shuts down without error notification or anything. This happens during times of high resource usage like lots of icons being rendered etc. I think it started to occur after the big (Gmod 13?) update but at first i thought that it will fix itself when i upgrade the computer, but it didn't and i still don't know why it happens.

The second problem is that textures look really strange. Now i don't really know if it's just Gmod or all source games, but some things look weird, mostly the HL Source things. The foliage sprites are also distorted badly. I have pictures.

The third problem is i think a little more known one. The blood and explosion effects are from TF2 instead of default.

The texture part is completely expected, you are combining different games on same engine that use same texture paths, conflicts are expected.
