recently connected to your system. Storage device like Flash Drive, CD, Hard Disk etc may bring viruses from other computers if they are used outside.

Check the power cable connection coming from SMPS to Motherboard as well.

3. Dust on Mainboard – If your CPU box is not packed properly, then you may

see to much dust on motherboard. Use a air blower to clean dust inside of CPU box.

4.  CMOS Battery – On motherboard, you can find a round shape battery inserted. Which is nothing but CMOS battery to power your system clock and other stuff as 

well. If you system is too old or you have not changed the CMOS battery since last 1 or 1.5 years, then that may cause frequent restart.
