Well, I hope it is not the MoBo. That's not as an easy fix. I do however have about the whole computer taken apart. Gave it a very good dusting and cleaning.
So, I was shopping online for a PSU. The tower I have is a Aspire X Cruiser. So with that, I am going to go for a PSU made by Aspire. Going to get a 600w PSU this time. My old one is a NZXT 500w.

This PSU looks as if it was made for Aspire X Cruiser case.
