BSOD's and a constant "stutter"

I rearranged my cables, reinstalled the external fan that I took out due to noise issues and booted it back up, but the stutter is still there, if I play a song, I can still here the skip and distortion effect it does.

This GFX is fairly new though, and I've not got that much money to just spend on a new one, would reinstalling my old one do, just to see if the stutter goes?

That, however is a fairly difficult thing for me to do, not great with computers, are there any other alternatives it could possibly be?

It's not RAM or my GFX card. I replaced it with my old one which never had the stutter, and it remains, so do the BSODs.
I bought fresh RAM and replaced that too, no change.
