How can i fix my laptop?

[Kordakh]

Hello everyone, i just installed a new PSU and GPU. I think i hooked everything up fine, then my PC got shut down twice, i thought it was the CPU overheating. I connected the fan in more tightly, that may have been the problem. However, my CPU is having a hard time running basic programs. As Im typing this, my CPU percentage is fluctuating between as low as 10% and as high as 30% or even 60% at times!! Im pretty sure i have no viruses, infact, this issue didnt start happening until i installed the new parts. Is it overheating? BIOS upon bootup says my temps are like 37degrees celsius.
