It's probably NTFS.
Lets try Sony's restore which your computer should have:
Sony puts on a 5 gig restore partition on the beginning of the hard drive which you can use to wipe your system and do a fresh, factory install of your computer's op system.
Disconnect all peripherals, everything from the computer except the monitor, the mouse and the keyboard.
If you added a DVD drive, a slave drive, anything that wasn't part of the computer originally, disconnect it/them. You don't have to physically remove them, just disconnect them from the power and IDE cables. If you added
a PCI or AGP video card - remove it. Anything that didn't come in the computer when it was new.
Then turn the computer on -
From the bios screen, before Windows begins to start, press F10. This is supposed to boot the vaio recovery partition and let you freshly install your op system to the configuration it was when the computer was new.
Hope that works for you. From seeing what's written on the web about it, it has mixed results, but if it does work, it's better than paying for a set of restore disks which is your other option.
If this works, you will have to reinstall the devices you previously disconnected (one by one with reboots after each), and enable the Windows firewall (it wasn't enabled by default until SP2). Install your AV program (if you have one that came on CD)
Then ...connect to the net and go immediately to Windows Update and get all updates since your machine was new. Depending how old it is that could mean both SP1 and SP2. Set updates to download and install automatically.
Then download updates for your AV program or download one like AVG if you haven't installed one you had from a disk.
Then get your anti-malware aps and reinstall them. Update them and run scans.
Let us know.
