1. If you haven't opened up a laptop before, you might not want to go that route; getting some of those beasties open without breaking anything can be pretty difficult. Get a can of compressed air and spray it into the laptop's vents from the outside; that should force some of the crud out.

2. A RAM issue? Good thought; it definitely could be. You can "stress test" your RAM with two free utilities: memtest86, and Microsoft's Windows Memeory Diagnostic.

Ok, I'm new to the hardware issues.

Outta curiosity, why would ya think it to be a RAM problem?

Thanks.

I would think it to be a RAM problem simply because it's especially when the computer is being heavily taxed for resources (mostly playing a game) that it shuts down.

Yeah, RAM is a common failure point in cases of random shutdowns/BSODs, so although it doesn't sound like the most likely suspect in this particular case, it is worth testing to rule out the possibility.

Also- RAM faults can be subtle, exhibiting themselves only (as sykopath8 mentioned) during times of heavier resource usage.

Hi,

to do a test on the memory download Memtest from http://www.memtest86.com/

Its an excellant tool for testing memory.
