I have an acer computer. Recently the screen would fuzz and it would freeze. It could easily be fixed by turning it off by the switch which I now you are not meant to do but it is the only way to fix it. The blue screen of death appeared and said something about BIOS. I did a full system restore. I installed a few applications but the screen just said ''No Signal'' I rewired everything yet I had to restart it again. It will be broken again first thing tomorrow so I need help quick. Any ideas what the problem is and how do I fix it.
