When I am running two programs at once (ex. internet browser, winamp) almost 3/4 of the times my screen will freeze in about 30 minutes or less. What appears are vertical blue dotted lines across the screen, sometimes the lines are yellow but they're usually blue. The problem isn't overheating, viruses and I know its not a problem about not having enough RAM. I used a program to check the registry, scan for viruses, deleted programs i don't use and made sure a whole bunch of programs don't run at start up. I'm hoping its not a faulty hardware problem because I don't have the cash to take it to a shop or get a new one, i just bought it and started using it a month ago :(
