TSGL: Something seriously wrong with my PC

[Bo Maurin]

Hi Davis and all others who aswered my question,
Is it not unlikely that the power switch is to blame? I'm thinking of
the fact that the PSU light is blinking and there is a small tick-tick
sound from the PSU. How about the cmos battery? Should I try to change
that?

Regards / Bo

Bo,  

A cheaper first repair attempt might be to replace the power switch. 
It's possible it's defective and prevents the PS from turning on. By
detaching the control cables the switch is effectively removed from
controlling the PS and it comes on. You might even find some info on the
net about jumping or otherwise manipulating the control signals that are
provided to the PS through the control cable to simulate the switch
actions to further diagnose things.

Some links from quickly googling around:

Power switch for sale here for $2.99. Cheap enough to try before
replacing the PS:
