bsod install

I'm trying to install Vista on my laptop. It's a Presario R3120US, Athlon 3000+, 512mb RAM, 60gb HD. I get a BSOD when booting from the DVD during the 'Copywrite 2006' screen. This is my error:
Stop: c000021a {Fatal System Error} The verification of a KnownDLL failed. system process terminated unexpectedly with a status of 0x0000221 (0x846e99e8 0x00000000). The system has been shut down.
I also tried booting into WinXP and starting the install there. After setup copies all the files, and decompresses them, the system reboots and the extact same error occurs.
Any suggestions?
I'm currently trying the install on another PC in the meantime.

try reburning the ISO at a low speed, 2x recommended, also do a CRC check on the ISO to find out its integrity. Nero MD5 Verifier is a recommended choice. If setup still fails, its likely a bad download.
I use the one from Ahead Nero http://ww2.nero.com/nero6/eng/Nero_MD5_Verifier.html
Here are the MD5/CRC values for x86 or x64 depending on which every ISO you downloaded:
x86 - File Size = 3.12 GB (3,355,598,848 bytes) - CRC Value = 0x67E089E0 - MD5 Value = 0E733AB1A8E8FF9A8684FD3639332773 x64 - File Size = 4.01 GB (4,309,368,832 bytes) - CRC Value = 0x48697711 - MD5 Value = E43502D0A15EADD551119D5639859E04
Paste the MD5 Checksum for either x64 or x86 depending on which one you want check in Step 1, Step 2 - Browse to where you stored the ISO on your drive and open it and it will automatically start the varification process and generate the has in the third field, if it matches Step 1, then you are safe.
Have you tried alternative methods to installing such as using Virtual Drive software like Daemon Tools or NERO Image drive to install it the ISO? Also, you could try extracting the contents of the ISO to a folder in your existing operating system and launch setup from there. -- -- Andre Windows Connected | http://www.windowsconnected.com Extended64 | http://www.extended64.com Blog | http://www.extended64.com/blogs/andre http://spaces.msn.com/members/adacosta
