Computer randomly hangs

[ajhen314]

well i have had my setup for a little under a year now and everything has been fine until just recently. My system randomly hangs two consecutive times in a row and then works perfectly for a while. This is while i am in the os and am doing things like surfing the web and listening to music, nothing that should tax my setup at all. Any input you guys can provide is greatly appreciated.

Did you install or uninstall any software or drivers recently?

Do you have an antivirus program?

Just checking if it's a software thing before you spend money on replacing any hardware...
