I personally think that it will be a hardware problem but it might also be a faulty driver or something.
Did you all those errors in the same blue screen?
perhaps the ultimate boot CD wii do for you.
also check your memory and stuff like that memtest I think you really need a run.

Hi! So many different error messages indicates in principle to a memory error!

Test your memory once and may with the Vista built-in memory tester.

No, all the error messages that I have obtained last three days. I use Active Boot Disk memtest and I also do not run.

Have been replaced motherboard, new processor, and memory can be replaced now no longer install Vista, says my new PC is not Vista compatible. Will they install XP on again but that was at least still have with Vista had nothing but problems when Windows 7 also is promised for the future.
