A while ago i noticed my desktop cooling fans started to get a little bit louder, I payed little attention. Whether it is a coincidence or not I'm not sure, around the same time i started having my computer freeze intermittently and it became progressively worse. When i turn on the computer there are weird colors and shapes everywhere and it will eventually turn into where there are so many lines and such on the screen I cannot see anything and then it will freeze. From boot up to the time it freezes is about 1-3 minutes. I cannot boot from safe mode to see if it is software or hardware because of encryption. Any help would be great. I figure it is either a video card or motherboard issue, but then again I really have no idea. I also have sensitive material on the computer so taking it somewhere to get fixed is out of the question.
