Pc Crashes When I Play Gw

Hello.does Anyone Know Why On Earth When I Play Guild Wars
For A While My Pc Crashes.i Dont Understand This Happens Only When I Play This Game.when I Am Logged In To The Net Everything Is Fine.
I Scan For Viruses.spyware,adware Etc And Everything Is Perfrctly Fine.please Help Me If U Know Something.i Cant Stand This Torture Anymoreeeeeee.....

Wouldn't this be better in the Tech forum? Also, a bit more advice is needed. People can't really help you if all you say is "it crashes after a while". What are your specs, what happens when it crashes, does it re-boot your PC?

Finally, why the hell are you using a capital letter for each separate word?

Please stop capitalizing every word - it's really annoying. This post is in the wrong forum and is lacking some important details. It would help if you would include things like:
What happens when your comp crashes.
What, if any, error messages you get.
What your system specs are.
How long it takes for the computer to crash.
How long this has been happening.
If your computer has been acting unusually - for example, running slowly or making strange noises.
If you experience a lot of lag when running Guild Wars.
If the crashes occur when you perform specific actions.

Some possible problems, without having more information, could be that:
A: Your computer is overheating and you need to replace one or more of your fans.
B: Your power sink isn't working correctly and your hardware isn't getting power properly when GW draws a lot of power from the system.
C: Your computer needs a RAM upgrade and can't handle the strain GW puts on the system as is.
D: Your Guild Wars installation is corrupted and causes a crash when you try to do certain things.
E: A background program is working incorrectly and when GW boots up, the system can't handle both programs.
F: You have a virus/spyware that your anti-virus and anti-SW programs aren't picking up.

These are some of the most common problems, but without more details it could be any number of other problems as well.
