I have a 5 year old Sony Vaio desktop - Model PCV-7762 - that when trying to boot up won't boot, nothing comes up on display, and the lights on front of CPU and on the keyboard blink rapidly. Only thing can do is pull the power plug and shut off.

This has happened 3 or 4 different times over the last couple of weeks. Leave it powered off for 5-6 hours, maybe longer, and it starts working again for several days before the cycle repeats.

I can't help but assme this is the beginning of the end for the power supply or something - but never really experienced this before. Any ideas or advice on what is going on and how to resolve would be greatly appreciated.


You should look up in the manual for the meaning of those blinking leds.
