[NeedsHelpFast7897]

About once a week, my screen turns all blue with a black outline around the blue, and a screeching noise pattern comes out of my speakers / headset. This has happened two or three times, and I have no idea what the cause is. I tried to download Windows Updates to see if that was the problem but it says the website encountered a problem while trying to view it. I was wondering if anyone could help me out. Thanks a bunch in advance!
