Main processor [CPU] do not detect all the other peripherals. Any voltage loss can cause this. Your PCs motherboard need to be checked. It will be best to contact the authorized service centre for Sony; in this case. This is not a user detectable fault.

SOURCE: Sony Vaio PCG-FRV25 Cooling Fan Issue?

I was going to suggest overheating before I read your own diagnosis; Yes, sound like the fan, but you can check by opening up and watching it. Or install temperature monitoring software such as Speefan;
If it is the fan it may well be that there is only one possible replacement - officially. But it is usually possible to cannibalize something cheaper to suit your purpose!

Put the cd in and restart. If it doesn't give you a message to press "x" to boot from cd, then you need to chage the boot order in the BIOS.

To get into the BIOS, restart and press del or F2 (it might say something on the screen like press del to enter setup) that is the BIOS.

Change the boot order to CD first.

One of the function keys should get you into the boot menu, F9-F12, to manually select the CD/DVD drive. Pressing Esc or Tab on VAIO logo may display the right information to show which key to press.

Sony pcg-7a2l, vgn-fs620/w no power on Mother board or power inverter?


If you aren't getting any response from your laptop then it may mean a component within the laptop has become faulty. It could be the CPU or mainboard. I suggest taking it in to your neares PC store and have a technition first handedly diagnose and single out the malfunctioning parts.

you shouldn't need to have to press f9 to boot from cd rom if you have it set in the bios as the first boot device , are you sure the copy of windows on cd that you have is bootable. Try booting from the disc on another laptop or pc and see if you can start it



Another option to try is to boot from a usb drive


instructions on how to do that are here

http://www.xtremesystems.org/forums/showthread.php?t=118576

once you have booted to usb you should be able to access the cd rom

depending on what version of windows you are trying to install you will need to run different programs.

you could also install vista or windows 7 to usb drive and install it from that, it is much quicker than installing from cd/dvd you would need to be able to boot from usb to start with though

how to install vista or windows 7 from usb instructions can be found here

Sony vaio pcg-k33p Won't power up


I had one with the same symptoms, the way i fixed it is by taking it all apart and resolder the system chasis grounds on the mother board, then reseting the motherboard's memory battery. A bit complicated for those with little knowledge on computer repair. You may have to take it to a computer shop, or try fixing it yourself. It took a while to figure it out.
