P105-S9337 Problems - BIOS?

Question

Aloha, I have a friend who has a P105-S9337 that came preinstalled with Vista Home. He came to me after he installed some softwares noticing that it didn't work as fast as it should. I've taken a quick look and discovered that it had automatic updates turned off for the entire 3 years he had it (he bought it new) so it had only 1 update done, 3 years ago. Also turned off was the firewall AND he had no antimalware running either. Needless to say, I found malwares by the many hundreds (nearly a thousand).
After spending nearly 2 weeks cleaning it up (the first 5 days just learning Vista, I'm an XP guy), I finally got it up to the point where it's working half decently and fairly well protected (caught up on the updates, turned on firewall, installed Kapersky antivirus, scanned and scrubbed with kapersky, SuperAntiSpyware, ccleaner and several microsoft anti-malware tools). Unfortunately, he panicked after hearing me grumble about Vista that he went out and had Windows 7 installed by his brother without telling me. In the process of installing 7, the brother erased the recovery partition in which the vista and P105 installation files was kept. Turned out AFTER the fact, that 7 had even more compatibility issues with the softwares my friend wanted on the laptop. To say nothing of fact that half of the hardware didn't have any drivers installed. He turned to me to fix this problem.  After lecturing him about jumping into the fire without checking first, I tried to find the drivers needed to make the laptop work.
After spending over 2 weeks of banging head against the proverbial brick wall, I gave up and decided to install XP onto the thing, figuring it could'nt be worse off trying this. After all, I've had fair success in past with backdating other pcs to XP, the only difference is that the P105 was the newest machine I've attempted to backdate. I've downloaded all the drivers and files i could find on Toshiba Europe's website, including an instruction listing the install order. The mistake I made was not checking on the version number of the BIOS 'update' before flashing the BIOS. Turned out I put in the wrong one, v3.3 instead of v4.7. After I did the BIOS and then installed a version of the Software Update Package, the whole laptop froze. Literally. The ONLY thing that was semi-functional was the mouse, i could move it but couldnt click or drag anything. Even the on-off switch didn't do anything. Was forced to pull plug on the ac adapter and pull the battery.
My problem now is that the laptop will only turn on the lights behind the speakers and the indicator lights for the ac adapter, power on, and harddrive. The screen remains blank and nothing else happens. Oh yeah, I can hear and feel the harddrive and or optical drive spin up (don't know whether they stay running tho). Holding the power switch turns off the speaker lights and eventually the hard drive and power indicators turns off too. Of course the AC and battery light stays on (ac adapter still plugged in). I think I messed up the BIOS and in so doing this locked myself out of the laptop.
My question is this: What can I do to fix this mess? I suspect my only option is to take the P105 to an authorized toshiba tech and have him/her reflash the BIOS directly. But before I do that I figure it would'nt hurt to embarass myself and ask you guys whether you have any suggestions before giving the money to the tech. At worse, I'd have to deal with you guys telling me how dumb I am. At best, maybe someone could suggest an option that would fix this laptop with minimal fuss. Thanks in Advance (and I beg your patience in reading my lengthy post).

PS:  I've since found out that my friend only has an UPGRADE cd for Vista which would be useless in this case, so I've bitten the bullet and have went out and bought an unused copy of Vista Ultimate.  I intend to return the P105 back to Vista as that's the only thing that has proven to work on this thing.  I just wanna restore the thing back to Vista and rid myself of this headache.

Best to order the discs from Toshiba. All the drivers and so forth are preinstalled and Windows is preactivated. Save yourself still more headaches.
