random BSOD: DRIVER_IRQL_NOT_LESS_OR_EQUAL usbport.sys / nvlddmkm.sys

I never post in forums, but i saw how helpful ppl here were so i thot i'd give it a shot. I was honestly ready to throw this pc into the dumpster so any help I can get will be greatly appreciated.

This is my gf's custom pc she built herself about 6 years ago. I has been used and abused by her siblings. It was having all kinds of problems so she had a friend look at it and clean everything inside. It was still crashing so I reformatted and reloaded the OS, trying to just get a clean start. Although, the issue of crashing has been improved through this, it is not cured.

I get BSOD while playing games, surfing the web, while sitting idle, after coming back from sleep, pretty much anytime. Sometimes I get no BSOD for hours, other times its more constant.

I am pretty much a tech noob and ive tried everything i know of. Anymore info that is needed plz tell me and I will post it. Thanks for taking the time to help me out, id really love to save this PC

Thank you
