I'm not sure exactly what is going on with my computer. It will boot up kinda weird at first, it goes to a black screen with a solid white line like it wants to open windows boot manager but then starts loading my OS. The major issue that I am having is that my computer will work for a short amount of time, but then it will just freeze. I am still about to move my mouse around and keyboard still responds but no program will open/move and it sits there for a minute or two, then resumes as if nothing ever went wrong. I have tested everything I could think of. I re-did the OS on the hard disk, changed the wires, checked each ram stick, updated the BIOS. Any ideas/advice would be very helpful
