Problem with Sony Vaio pcv-rx860 (screen goes black at startup)

Problem with Sony Vaio pcv-rx860 (aka pcv-7762) desktop--screen goes to black at startup and computer won't power up. It belongs to my mom so I'm not very familiar with it.

When I press power button, the computer comes on and ''Sony'' appears on the screen. Then screen goes black. I hear a fan whirring sound when I first press power button. Within 15-20 seconds the fan goes from louder whirring to much softer. I took the cover off and don't really hear any sounds coming from the hard drive. One thing to note: I installed extra memory the day after Christmas and the computer worked fine until end of March. If memory was the culprit, wouldn't problems have occurred immediately? Thanks in advance for any help.

I would suggest first to try to take one stick of memory out and try to boot up the pc. Sometimes, one or both of the memory sticks can go bad or the memory slot on the motherboard itself can go bad. If that is not the case I would then remove all of the usb connected to the computer and last i would test the power supply.

Sony PCV-7762 Service manual


First of all, the Sony Vaio desktop case is like trying to open Fort Knox. It is quite well built, but hardly gives any clues about how to open it to work on it inside. Here's a link that specifically addresses this situation:
