dell cpu auto restart repair

The DELL computer CPU came in for repair with the problem of auto restart issue. This means that it can starts to reset even without you pressing the reset button and sometimes it can auto reset many times within a very short period. Turning the CPU off and On does not help at all as the problem will resurface again.

The first thing to do is to open up the cover and check for bulged e-cap because for computer motherboard, bulged e-caps are commonly found. When I looked at the motherboard, I was a bit surprised to see so many e-caps either swollen or had its liquid chemical spilled out. See the pictures 1 & 2 below:

Total bad e-caps found were 11 capacitors- 1800uf 6.5v (8 pcs), 1500uf 6.5v (1 piece) & 820uf 6.3v (2 pieces). Once all the bad e-caps were replaced and powered On, the CPU came back to life without any auto restarting issue anymore.

    Good fix Palanisamy! Those e-caps keep on bulging or creating problems. it is about time they replace these old ones with new formulas.

    I have a Dell that started crashing, but all the capacitors looked good. Ended up putting a little silicone oil on the CPU pins, and the problem never returned.

    The title was a bit misleading as the cpu is a chip, ie the microprocessor, whereas, you were talking about the base unit as a whole unit not starting up.
    I was expecting an article about the microprocessor (cpu)
