Computer Freezes Up Randomly

I know this has nothing to do with Combat Arms, but I was hoping you guys
could help me solve this problem. About every 5~30min, my computer will
freeze up. When that happens, Im not able to move my mouse or anything. It also freezes when I play Combat Arms. I also tried running Norton/ Advance System Care to find out if I have anything virus or trojans, but they always come up clean with no issues. So I went online and did some research. The people said that it may be a hardware/video card problem but Im probably sure it's not that. So I just hope that the MPGH community would help me solve this
problem.

Try disableing your antivirus when playing,
Also. Does this only happen when playing combat arms?

It could be your anti virus sucks and it doest get all the viruses, So try to find another one and do a scan. See if that will fix it.

Format ur Pc@

It could be so many things that cause the same effect...

It could be that you don't have enough RAM to support all the programs you have running
Or Your Graphic card is taking a dumb
or you have a Virus

Like markoj said, see what is your CPU%, if it is a High number see what process are causing this high CPU%, If they are all process needed to run your computer and the internet, you will most likely need more RAM

If its your Graphic card taking a dump I can't help you there.....

I would Recommend a different Anti Virus Program like goggleeyes30 Said
I recommend
AVG or Avast
