Windows 7: BSOD on initializing chkdsk, no cursor, few rows of colored garbled pi

BSOD on initializing chkdsk, no cursor, few rows of colored garbled pi

Hello all,

I tried to do a routine (once a year) chkdsk via the command prompt
> chkdsk /r
> shutdown /r /f /t 1
. And upon the reboot, all I get is a black screen, no cursor, with ~4 rows of rainbow, garbled pixels at the very top of the monitor (certain pixels occasionally change colours). This occurs before the windows splash screen. I have left the computer as is, hoping it will eventually boot on its own with no luck.

Can you help me please? I haven't had any problems, and this was just a routine check. Some more information, I dual-boot with Ubuntu. I can mount and access the windows partition from Ubuntu, and I even ran ntfsfix in Ubuntu (which has some analogous functionality to chkdsk), but it didn't notice any problems, nor did it solve the issue.

Thank you for your help,

Hello again, eventually this issue 'resolved' itself: I waited 3 hours and the computer rebooted, and windows 7 has loaded successfully. Is this solved? I suspect that chkdsk was running after all, but it was the GUI display that was garbled, giving all external appearances of being a BSOD, aside from the mysterious rainbow pixels at the top of the screen.

I will flag this as solved, however, I would still like to know why this happens? Is there something wrong with chkdsk? a graphic driver?

After CHKDSK, black screen with cursor
After I came back to logon after turning my computer on it was going through a CHKDSK. Knowing it hadn't been done in a while I let go thinking it would be done in about 30 minutes. I was wrong and when I came back it was defaulting security permissions. This took upwards of a day and when it...
