There is something messed up with my computer.

First of all, I get this message every single time I turn the computer on.



Also, when I go on Google and search something like say this link http://www.google.ca/search?hl=en&q=...e+Search&meta= and then click on the first link, it shows me this link http://go.google.com/?id=6827343&aid=61&said=v2test7 (DONT CLICK ON THIS) And then it tells my system error and tells me that its gonna shut down in a minute.

Also, on random times my computer decides to hang up out of nowhere and then I have turn it off from the CPU.

I have scanned the computer twice and have found no virus in it.

One thing that I did do was do the Disk Cleanup yesterday for the first time. I think it might be because of that.
