My laptop seems to heat up very quickly while I use it and it eventually shuts off. After waiting for a bit and turning my laptop on it repeats the same thing.
Is dit een goede vraag?

Your fan may be failing. I would listen to see if you can hear the fan running when the computer is performing a task. If the fan is silent, it may need replacement. Try following this guide: Acer Aspire 5742 Cooling Fan Replacement

The Acer Aspire 57xx series (especially the 5742s) are well known for running very hot, mine shut down a few times as well. You could replace the fan and heatsink (requires system board removal) or set a lower maximum CPU speed in the power plan/BIOS (negating any advantage of choosing an i5 model over a basic Pentium).
