Win2000Pro BIOS virus?

Gosh! I hope someone can help me!
I am running Win200pro and must have downloaded some kind of virus from God knows where! After 4 days of trying to repair the destruction myself I am on my son's pc now looking for answers to the damage I have unknowingly done to my machine. I reinstalled Win200 over the old for fear of losing drive contents with complete format. I went to copy contents from master to secondary and the Drag and Drop feature as well as Cut and Paste were not functional! Screwed there! I went to FTP drive to upload drive contents when that didn't work (feeling the desperation of working against time) and no network components were installed after installing Win2000 again!
I am afraid that it's in the BIOS now! I have master and slave hard drives. Master is of course Win2000. I was getting error msgs with "svchosts.exe" and "tcphost.exe" ( or something like that) and also at boot I kept getting this Windows Installer pop-up trying to execute and install something. I checked under RUN in the registry and it was Microsft Synchronizer Manager. I had no control whatsoever over that even after continuous attempts at deleting it from the registry and deleting the files associated with the program! The files just kept popping back up in the system directory along with the registry being re-written with the Synchronization Manager keys! Everytime I tried to open Windows Explorer the Windows Installer would just pop up! It also popped up when I tried to open a few other progs (ie: Partition Magic) I took out the master Win2000 drive and put another one in from a Winxp machine and set it to master. The screen would get to the WinXP starting message and then would just reboot over and over again! It did it 3 times! After that I just said SCREWIT! and was close to just tossing the 120G drive out the front door! I can't afford to lose this expensive data because it contains FULL progs of Adobe Photoshop, Corel Draw, PSP, Macromedia and lots of DVD and music burning software. I have a home/business network set up and don't want to start a chain reaction!
I don't know what other info anyone needs in order to be able to help me but I am hoping some kind soul with expert knowledge of Win2000Pro, BIOS, and viruses can help me with a salvage operation.
I am at wit's end and need my machine (and the data on that drive for my much needed job)

My email is posted but just in case you don't see it:
beachnmama@hotmail.com
I am sitting back with head in hands waiting anxiously (lost all patience DAYS ago!) some expert advice because someone told me that I could get it here!

Everlasting gratitude!

If you have virus, probably not in bios.
You said took another HDD drive(xp on it) from another pc and tryed to boot
That wont work due to differances of mobo, hardware, etc, The Only Way That Would Work is if the two pc's were identical, mobo, hardware, etc.


Here's thought remove HDD with valuable data from pc.
If you have extra HDD install it and format & load windows
Then if pc working good, you can install the hdd with valuable data on it as spare, then you can access it and salvage your data.
But possible what ever virus or bug you have could corrupt your new install of windows.
you probably can try to clean or scan your valuable data HDD before access it for data

If you can still boot to your Valuable data HDD maybe can try to clean it first??
There is lots of Treads and posts here at MG relating to virus and removal of, search the Fourm

P.S. Im not expert just trying to help, there may be other options, someone else may post up some help

 

Not an option.
