I used to have windows xp. While using it my computer would occasionally freeze up for a second and then go back to normal. It usually did this about every 10-20 seconds. If I jiggled my hard drive SATA cable the problem would go away and then come back about 1 to 2 weeks later and I would just jiggle my hard drive cable again. I repeated this several times until I installed Windows 7. After installing Windows 7, the freezing happened much much more often and while it was freezing and for a few minutes after, my internet would die. I couldn't make it go away by jiggling my hard drive cable. I cleaned out my computer and the freezing lessened a lot, but, after a while, it came back just as bad.i reinstalled windows 7 and it didn't help at all. Eventually, I discovered taking out one of my RAM sticks lessened the problem a lot, but I ran memtest and it found no errors. I tried plugging my hard drive cable into a different SATA port and the freezing went away for an entire day. When the freezing came back I used a new SATA cable and the freezing didn't go away at all.
I've thought back to the time my computer first started doing this and I can think of any trauma that could have occurred, except for perhaps when I took my computer to a friends house it got a little bumped around, but not much and I think that happened after the freezing first happened.
Any help would be greatly appreciated, my computer has barely been usable for almost a week now.
