Help , problems with my setup

[hellgrabbit]

Hi guys.
I would really apreciatte some help please.

my components are:

- graphics -> GEFORCE GTX 750 TI
- motherboard -> msi z97M-G43
- cpu -> intel i5-4590
- psu -> corsair cx 430-430W
- Ram -> 8gb ram


I've been having a lot of problems with my computer, built last year.
I've no idea of where the problem could came from.
when i put my games (CS:GO or Battlefield4) specs a little higher (principally shaders), after some time the computer turns off and restarts.

With lower specs this doesn't happen.
games are the only problem here.

Can you tell me where the problem could be at?
I've no clue.

Thank you

What sort of cooling are you running? Seems maybe when you up the settings the gpu is working harder and perhaps overheating, same with the cpu. I'd download temp monitoring software for the cpu and gpu, and check to make sure that one or the other isn't overheating. Also stress test the cpu and gpu, if there's a problem with either one when load is increased the fault will most likely replicate and you'll know what the problem is.

Could you tell me a good stress software to both gpu and cpu?

Thanks
