Windows will not load after "new hardware change" messege.

I searched on google for this without any luck, heres what happens:

After the computer boots up it does its usual scanning of hardware on your PC. However, after it scans my RAID drives, it detects them, then i get a screen that says:
Windows could not load due to recent hardware changes, then it gives me options like start windows in safe mode, last good know config, start normally, etc.
No matter which option i take it reboots the computer and it does the same thing all over again.

I didn't have this problem before, however, i did change my power supply, i went from 310W to 450W. and i made sure all connection are right. please advise.

 

also, i connected a DVD-rom.
from another PC that it was in and i out it into this one, and i never had any issues with it.
Also, i just booted windows disc to try and reinstall windows, it doesn't even allow me that after it displays "press F2 (or something) for Automated System Recovery the screen" just freezes and no more text appears. All i see if the winxp setup Blue screen, blank.

 

ok i was able to figure out what the problem was.. and it was with the power supply. I installed my old power supply and evryhting is fine and dandy, however, i'd still like to use the new power block since this is my system config:

P4 2.533
Asus P4B533 Mobo
1GB RAM
Canopus DVStorm (Video Editing System)
Matrox Millennium G550 Video Card
DVD-ROM (Generic)
DVD-RW DVR-AO9
Floppy Drive
4 HDD
- Rocket RAID (2 Drives) = 160 GB
- Promise Ultra133 (1 Drive) = 200GB
- System Drive 80GB
SounBlaster Live 5.1
LAN Card
FireWire 3 Port Card
4 Case Fans

As you can see i got a lot of hardware that requires power, although i never had problems with 310W Block, i just wanted to upgrade after 2.5 years.

1. What do i need to with the new 450W block?
2. is it busted or what?
3. shoudl i return it?
4.or are there mobo jumpers that i need to change?
5. or is there somthing in the BIOS i can tweak?

 

If you switch out power supplies and everything works then yes it is your power supply. There are no jumpers that control your power supply to change. I would take the new power supply back and have them switch it out and try again. You said you checked to make sure evrything was plugged in right so more than likely the power supply was faulty and not pushing enough power to one of your devices.

 

ya, i checked all cables and connections.
I'll return the damn thing tomorrow.
