My fan goes crazy & then PC restarts??? HELP!

Edited: My new computer all of a sudden makes a real loud noise and then shuts off and restarts. I'm pretty sure the fan speeds up like 10 times as fast for 3 seconds and then the PC shuts completely off and then turns back on. It's been doing this all day about once per hour. The first time it happened the PC had only been on 30-60 minutes. Its not that hot in the room either. Does anyone have any idea what is going on?

Does anyone know a forum where I could get an answer to this, like a technical site forum?

I need help!

Is this happening in a continuous loop or it just restarts every hour or so? Like reboot, cuts off / reboot, cuts off etc.

Also, does your screen turn blue when this happens? After it reboots, does windows give you options to boot in safe mode or does it act like nothing happened?

Are all of your heatsinks/fans etc, seated correctly and securely?

Even if it isn't too hot, parts can still get hot enough to reach the shutdown temp.

check the temperature of your processor. a ghetto way to do this is while your pc is running, and your grounded, touch your heatsink, if it's not hot, it's not seated correctly.

I wouldn't rule out a power supply problem, like it's broken. try swapping out a new one if the overheating isn't an issue.

Do you think if I get another one of the same thing it may have the same problems? How likely would that be.joeamis

just have them fix it, if they gave you a warranty when you bought itthey are obligated to fix it.

Its not a place that even could fix it, so I'll be trying to return it completely. The one thing that puzzles me now is that while the turning on the PC problem was there from day 1, the restarting problem just started a month after getting it.
