I have a Sony VAIO VGC-RB43 desktop with a Bestec ATX-300-12EB3-Rev.S3 power supply. The computer will not power up. The fans will not come on. Measuring DC volts on pin 9 (purple) of the mother board ATX...


Open the power supply case (be careful due to high voltages within the power supply) and look for swollen (tops are domed) or burst capacitors (tops have cracked open due to excessive swelling and the electrolitic fluid has leaked out). We have found this to be a regular problem for systems that have been running constantly for a long period of time. Also, look at the power caps on your mainboard (big ones nearest the CPU) and check for swelling or bursting. I just had tis issue with a Sony Vaio in that the caps in the power supply had started to swell. The system continually rebooted. Have seen the caps on MB's burst as well.

Not powering on after power outage


Hello,

Sometimes after a power outage, some power supplies can take a hit but will not provide the needed voltage to operate your pc. In this case you should replace the power supply. For future protection, connect your pc to a power strip or power source with surge protection. This will range in price from $7 to hundreds depending on how much you need to protect and your budget.

Good Luck

You may possibly have a bad video card and a bad circuit on your motherboard. I would have the motherboard replaced. Some motherboards come with video cards, so once it is replaced, you may alerady have a new one with the motherboad part. If you not versed in doing this, you may want to get a professional to do so.
