Portcls.sys keeps blowing up on a Thinkpad R61

Clean install of Windows... ran all of the updates.
Sound in Dev Mgr still not working, so I grabbed the Realtek AC97 drivers from a bunch of different sites.
Every time it tries to install it, portcls.sys blue screens!
Laptop worked fine before - prev hard drive's integrity was in doubt, machine was also infected badly with viruses.
I've gone to Realtek's and Lenovo's site for different drivers - no luck.
Also used Driver Detective - no luck with that, either.

 Sure...

  0X0000007E, 0XC0000005, 0XEDB6A46D, 0XF7B6AA74, 0XF7BCA770

  Also note that I put SP3 on this sytem before attempting the audio driver installation.
 
 I'm pretty sure this is not a "high definition" driver issue...
Ooops... my bad..I actually have SP2 on there at the moment.  The other Lenovo I'm working on has SP3.

Try everything in the article, and let me know if it helps.
Sorry this came in three parts, i wasnt sure how many answers i could get. The laptop is a Levono Thinkpad R61? not an R61e or R61i? Also what is the type and model of the laptop? It is running WIN XP correct?
Thanks for your reply postings so far... actually this is an R51 - the stenciling is rubbed away a bit.  Now it is XP Pro Sp3 - I installed SP3 in case there was something in there that could be helpful.
Is it possible for you to tell me if it is just an R51 and not an R51e or i? It would help to know what the type and model is as well. Thanks.
Sorry - Just an R51... Type is 2883, 2VU
Try this one first, as it seems to be your best possibility.
