Vista - BSODs after latest updates

Hi:
I updated my desktop and a laptop on Saturday - the desktop runs x64 on an AMD quad platform, the laptop runs x32 on an Intel Duo platform.
Sunday morning both machines, for the first time in years, went into BSOD frenzies, reporting all sorts of weird and wonderful problems, blaming hardware, then blaming software, then blaming hardware again and so on.
Rolled both back to pre-update states, removed AV software and ran a number of diagnostics and so on, returning some semblence of stability to the machines, but am still getting nasty blue shocks, often on startup.
I have avoided trying to boot after a hiberation -- turned it off on both machines -- and that seems to have helped somewhat.
Sorry for the long-windedness, but I wondered if anyone else has had a recent spate of BSODs.
I would ordinarily just it put it down to a random probem, but two previously solid machines on two different platforms seems more than coincidence.
I ran compete antivirus scans on both and have so far discovered nothing out of the ordinary.
Thanks for any help,
dg

Uninstall the newly installed updates.
Or go to c:\windows\ and delete the SoftwareDistribution folder and restart the computrer.
Then, try updating windows.

Thanks
I'll give it a try

Hi:
The updates were the latest from Tuesday, 10 Feb. The laptop seems to have recovered since the rollback and adding a new (beta) video driver. The desktop is better, but still not what it once was. Perhaps a new video driver is needed there too, or an older one.
