For about half a year now my computer has been randomly freezing up. Everything will stop and when I try to bring up the task manager, I will recieve a "security" error.
To fix this, I shut down my computer by holding down the button on the front of the tower until the computer completely shuts down. I then let it sit with the side open for a few hours to cool it down. I restart a few times but the problem continues in shorter intervals until the computer won't even start up anymore. I then run start-up repair.
Start-up repair doesn't find any problems so it does a system restore. Once this is complete, the computer runs fine for a few more days. However, the past few days, I have been having this problem every 9 hours or so. Just today, I have had to do four system restores.
When I try to run games which I was able to play fine last week, I will play them for about 30 minutes and recieve an "out of memory" error.
I checked how much of the RAM my computer is using when just sitting on the desktop with a majority of the background tasks closed and it's using about 56% of the 3GB.
I have scanned for virus' and found none.
