Win 7-64.
I've had shutdown problems for a while - permanent hang. Today I could not boot back in, not even Safe Mode. "Last known good" worked two times so I tried a clean boot, no go. Now I can't even boot "last known". My pretested repair disc and the reinstall dvd from the mfr. make it through "Windows is loading files", then a 90 second blank screen, then reboot. Even Ophrack live cd dies before loading.
Any ideas would be appreciated.

Thanks for reply. Dig this, while slaving on my crappy netbook to issue the plea for help I noticed a suggestion to unplug USB peripherals.
Duh.
Of course your questions suggest that you didn't understand my quandary. The computer (i7-2600 3.4 GHz "Sandy Bridge") would not boot up. TO ANYTHING. Not even system repair, installation, Ophrack Live CD or Ghost bootable disks. It started to run, then went blank and eventually restarted the loop. Insanity. All I got to see was the windoze four colors. Then nothing.
The culprit was a powered USB hub that had an intermittant power brick to AC connection. Who knew that could cause such havoc? Once I repositioned it my problems were over.
I probably could use a new or bigger power supply but this is the crap Dell spec'd out.
Anyway, thanks. I hope you suggest disconnecting nonessential USB's first for boot problems next time while asking irrelevant hardware questions.

EXCELLENT!

Good for you that you were able to discover the cause.

1 of the steps of my troubleshooting guide for boot problems is to disconnect all peripherals except the mouse, monitor and keyboard.

Thanks for marking the thread solved & providing the steps you used.

It just started acting up again. It locked up while working. After a hard shutdown I got a 0X000225 "The boot selection failed because a required device is inaccessible" No safe mode, no nothing. Attempts at booting off a system repair or windows installation disc make it through "Windows is loading files..." then "Starting Windows" , then a long pause and a restart. The only things connected are keyboard and monitor. Help.
