Troubleshooting Suggestions for Computer

[Jack H]

Hey guys, my parents have a somewhat old dell computer that I recently put a crucial mx100 into and reinstalled the operating system on it. I used the original Hitachi 500GB drive for storage. It has 8GB of RAM, a Intel i7 860 1st-gen processor, and a dell motherboard (not sure which one). The model is a Dell Studio XPS 8000. I think it's about 5 years old?? Anyways, I'm having problems where the computer will completely freeze up, I'll get a white, line-filled, screen, sudden shutdowns, etc. It seems like it could be a blown motherboard capacitor, but I don't see one. The computer was freezing up before I reinstalled, so I do not think it is a corrupted install. Any suggestions/advice?

Not much. Looking for some ideas here, not sure what I should target.

Very similar. Kind of inverted colors, with a lot more white than black. Also, it seems to appear in kind of blocks of white and black staticy stripes. I'll try and get a pic next time it happens.
