Re: Vista Ultimate Install Failure
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.
