Ok, what operating system are you using? Have you installed any new programs? How old is the computer? Have you run any anti-virus/anti-spyware programs to clean up any crap that may be on your computer?

I got the computer about 4 moths ago.

Is it overheating?

@Gamrz360 And all the other stuff?

@papayalily I added it to the description.

It sounds like a hardware fault more than a software problem. The usual suspects are CPU over heating, dodgy motherboard or memory fault.

If its a Dell and it’s only 4 months old its still covered by the warranty. Phone Dell up again and get them to fix it.

I second @Lightlyseared and also want to add that the best time to call support is at night. Usually you get right through.

”and I have installed a Virus program called Microsoft Security Essentials.”

Did you install this from a pop-up window?

No, I bought this apart from the computer at Staples.

MSE is about equal to McAfee, so a virus is unlikely (though still possible), so I doubt that’s it. Besides, it doesn’t really fit the symptoms. It sounds almost like what my systems did when the heatsink got clogged with cat hair. Of course, I also had similar issues when I had a bad DIMM (memory module) and you really can’t diagnose that yourself without a little knowledge.

In either event, I am with @Lightlyseared on this one.

Sure its looks like the hardware problem. so contact any service center… its better….
