I am having this problems since around 5-6 days. My computer gets hang, mouse pointer gets lost (invisible), and key strokes work after a lag of 1 sec to 3-4 secs. After a few seconds (say from 3 secs to 10-12 secs), it will automatically get to normal state, like nothing weird has ever happened.
This mostly happens when I am playing AOE II, (Age of Empires TC, a game released in 2000 does not need much resources of computer, runs on 128 RAM). Then this also happens (with lesser frequency) while I use Google Chrome or Firefox. (I seldom use IE).
Also sometimes keyboard will work and I can see mouse pointer but cant move mouse pointer. This has happened only 3 times, and everytime i needed restart to fix it. (the problem above this has occured like atleast 30-40 times)
I downloaded and tried to fix it with CCleaner, though it freed up some space, but did not help me in getting rid of the problem.
Following are the config and settings of my computer.
windows xp pro, version 2002, SP2
computer: Intel P4, 2.40 GHz, 512 MB RAM, Gigabyte mother board, intel chipset 845.
pretty old but this is what I have.
I have uninstalled my antivirus -claimwin or something- 2 days ago, which anyways did not seem to do any work, in attempt to free up the load. So I have no antivirus installed as of now, but I never download trojans or virus from internet or pendrives.( I only use the computer so there is no risk that someone else could download; I use cmd prompt to delete virus from pendrives if any). I have my windows firewalled on, with few exceptions added like AOE, and few port forwarded like 2300-2400 and 47624. I dont know if this could get me in any kind of problems but mentioning just in case.
PS: Computer hanged four times while writing this post (in 10-15 mins). (Opened appication: MS word , Chrome -only this tab- , and google talk).
