Vista - Vista Ultimate Install Failure

This is a machine that had XP Pro installed with no issues. Specs are a 1.8
Ghz processor with 2Gb memory. The install made it to the Vista desktop [but
no icons] but the install restart began a chain of failures. There have been
a chain of bluescreens and error messages. One bluescreen message was
"IRQL_NOT_LESS_OR_EQUAL". There were other references to hardware and video.
I switched to the video connection that came with the board but the same
error messages persist. Safe mode leads to the same outcome. Seeking
guidance in troubleshooting.

You really didn't give much to go on--
Irq not less or equal is an error message that can be caused by hardware
failure, Obsolete/incorrect Drivers, overclocking, etc.
In your case, I'd start at the MBD level, and see if an updated BIOS and
possibly chipset and USB drivers are needed/available.
Then, I'd likely move on and see if the video driver needs updating.
Finally, the other device drivers for printers, LAN cards, etc.
The Lan card drivers are also a commonly found source of your problems.

You might be able to get a successful install by removing non essential
devices & I/O cards/adapters, leaving the keyboard mouse, video card,
hard drive, and CD/DVD drive. Then things are added in one at a time until
everything works, or the last installed device causes the problem.
