From past one week my system (intel dual core processor on DG965 RY board with 500 GB SATA HDD, 512 MB RAM Winxp Pro service pack 3 OS) is getting switched off, the very next moment it switches on. This happens sometimes during POST, during initalisation of OS, during Login time, sometimes after 2/10/15min/Max 2 Hr of switching on of the system.
I have done following things:
I removed dust from the fans (both on processor & SMPS), both the fans are woking properly.
During safe mode system restars.
What could be the problem, whether problem with SMPS or something with motherboard.
