Hi, I am having trouble with my gaming PC crashing. At first it started to switch off after the game getting laggy and then randomly switching off I have checked the temps and the usage. When its about to crash its 100% and around 105 degrees celcius CPU was around staying around 45 degrees and running around 50%.. Would it be a fault with the graphics card? I think i might of had overclocked it before it happens so i redownloaded msi afterburner but it wasnt overclocked. I know a bit about PCs but not THAT much. Also just to say the whole thing started when my thermal paste dried out, although i replaced it regularly, it still happens. I replaced it last night and its happening now. Should I be Looking at a new graphics card? I dont have much budget to buy one though.
ALSO
It doesnt crash on like normal stuff, just games. although while on yt and stuff its like 80 degrees.

I have a gt 630

On the CPU or the GPU? If the GPU, did you make sure the pads weren't removed?

although i replaced it regularly
How often have you done so? Thermal Interface Material(TIM) shouldn't dry up on your GPU on a regular basis. If so, it means you have an improper mount or you're vaporizing your TIM taxing your GPU to breaking point.
