Sony VAIO PCV RX755 will not boot up, nothing on monitor screen, no beeps heard, fan for power supply is runnins as is fan for processor, floppy does not do anything after power is switch on, Hard drive lights comes on once, cd rom lights flashes a few times, can not boot with a CD rom or floppy. Have tried 3 different monitors-nothing. Anyone have any ideas?? TIA computer is 1 year 1 month old, purchased at Best Buy...any hope for warranty 🙂
 
You may want to try clear the NVRAM.

Shut down the computer.
Unplug the computer from power.
Face the back of the system and pull the metal tab on the top right corner, until the side panel opens.
Lift the side panel from the system.
Locate the Configuration Jumpers near the bottom right corner of the motherboard.
Move the Complementary Metal Oxide Semiconductor (CMOS) Jumper from 1-2 to 2-3.
Connect the power to the computer.
Attempt to power the system.

NOTE: The system should not start.

Unplug the computer from power.
Move the CMOS Jumper to the Default position (from 2-3 to 1-2).
Connect the power cable and power on the computer.
The computer should display a BIOS screen.
In the AwardBIOS Setup Utility window, press the RIGHT ARROW key until the Exit menu is selected.
On the Exit menu, press the DOWN ARROW key until Load Setup Defaults is selected.
Press the ENTER key.
In the Setup Confirmation dialog box, press the ENTER key.
In the AwardBIOS Setup Utility window, on the Exit menu, press the UP ARROW key until Exit Saving Changes is selected.
Press the ENTER key.
In the Setup Confirmation dialog box, press the ENTER key.
 
ok I tried that, it did nothing when the jumper was moved, but did power the cooling fans for the power supply and processors when moved back. Still have a compleely blank sceen. I think the motherboard may have failed completely. Could a virus cause damage to this degree?? Computer belongs to a friend so not sure what they may have done to it.
 
Might be a power-supply failure. I seem to recall that there was a batch of bad Sonys with that trait. Maybe call Sony tech support and pose that question to them.
 
Yes. A PSU can be bad and still provide power to the other components.
It would just indicate that the 12v leg is okay, while the +5v leg may not
be outputing enough.

Did you try reseating the RAM module(s)?

SONY's warranty is 90 days, so that is not even a consideration
(unless you bought Best Buys extended warranty service).
