My computer keeps freezing and i have no idea why. usually within the first 10 minutes of logging on to windows my screen freezes, sound stops and i cant move my mouse. there is no blue screen or anything i just have to shut down. I thought it may have been an issue with my SSD but I have done a clean install of windows on that and it did not help. I've tried changing sata cables/plugging into a different sata port. After installing windows 7 on a brand new 500 GB hard drive and it has not solved my problem so at least i know theres no problem with my old SSD. It has also frozen before I even start windows and while I am in the bios.
