I have an HP m8000n media center PC running Windows Vista x86 and decided to upgrade the PSU today. The PSU that I am using is the ThermalTake TR2 600w.
After upgrading the PSU, I received a disk boot failure upon first reboot. The system fan has also stopped working, though I have since replaced it with a new one (using the 4 pin power connector rather than the 3 pin, which no longer works). I downloaded a Windows Vista x86 system disc and booted to it, only to find no listed installations of Windows Vista -- and thus was unable to do a repair installation of Windows. I opened the command prompt, used bootrec /fixmbr, as I heard that the problem could be related to my master boot record, but that has not fixed the issue. Suspecting that it was the new PSU, I re-installed the old PSU and experienced the same errors. I am running out of ideas and would greatly appreciate any help that can be given. Thanks for your time and any help that can be given.
