UL30VT-X1 playing TF2 and L4D2 with weird issues

Hey guys, I've been having this problem for a long time, I've submitted the bug report to TF2, I've reinstalled L4D2 and TF2, and I've updated the G210m drivers. At this point I'm very frustrated and just want to play TF2

Issue #1: Whenever I crouch jump in TF2 and L4D2 it does something weird. After holding ctrl+space, whenever I attempt to move (w,a,s,d) the game will completely freeze. However when I release the key (w,a,s,d) the game returns to normal like nothing happened. In essence after hitting ctrl+space, I can't move anywhere since the game will freeze. I've had this issue so long that I just adapted to not crouch jumping at all, didn't hurt me too much

However.....now there's the second issue

Issue #2: TF2 just got a big update with a whole bunch of new stuff. After 5,10,15 minutes of playing the game will completely crash. I get alt-tabbed out, the game sound will keep repeating the last sound heard (I think you guys know what I'm talking about). Again I've updated drivers, reinstalled etc. I don't think this is a big issue with 99% of TF2 players since the servers are packed and no one is really bringing this issue up. I think it's something to do with my laptop.

Has anyone experienced this w/ their UL30VT? Does anyone have some advice? Please help!

I'm not sure if this is the appropriate forum to post this technical issue but I JUST WANT TO PLAY TF2!
