My ASUS K53E laptop is shutting down every three hours and it shows a blue screen (Windows critical error screen).

It has a Core i3-2310M CPU with 2.10 GHz, 4 GB RAM and Intel's integrated graphics.

This is a newly installed Windows 7. Maybe I have new hardware of software installed, but I didn't change any of my hardware recently. I still have guarantee on it, so I went to the store and they said it was okay and that there was no hardware malfunction.

Does anyone know what the problem could be?

Ok. You are going to need to edit your question. You need to add how long you've had this laptop for, the exact BSOD error, and what you have done to determine that the issue is NOT overheating (because the only reference you make to temps at all is in the title). Just saying that you "know" it is not overheating means nothing. I've heard people say that they are using their laptop on their bed, without anything firm below their laptop, and they "know" it wasn't overheating... even though they were clueless that they were blocking the cooling channel intake. – Bon Gart Jun 9 '12 at 13:59
The word laptop is a bad idea also, even putting it on ones lap can block the vents on some models. – Moab Jun 9 '12 at 15:40
