I had a virus that deleted one of my drivers causing BSoD to come up on boot up... all in the passed anyways while i had it i was using google searching for solutions.. and i see a "did you mean": black screen of death................................................. it matches your description perfectly and supposedly is a lot worse then blue screen, since its not something Microsoft put in as blue screen was... so what i'm saying is this error isn't supposed to be there (as in error i mean the black screen with monitor thing) (and yes its happened to me before) so heres what i want you to do...
http://combofix.net/download - direct download.
now even though it says "Malware removal blah blah" just try it to fix drivers etc, it does a lot more then remove viruses...
Some antivirus software may detect ComboFix as malicious; for example it uses NirCmd which is considered as a backdoor by many antivirus softwares so don't think i'm giving u a virus here -.-
anyways post the log update after it finishes back to me via pm/this topic..
*if it doesn't work i have a few more ideas in my mind so let me know!*
ALSO u said it happens after like 5 minutes ON BOOT-UP? if so it may be a program causing this, you can configure combofix to boot your pc without loading any of your desktop items.. etc, or just open task manager and end "explorer.exe"
im sorry to say if it turns out to be one of your programs doing this, you will have to re-download that program..
also if after ALL this it still wont work, check your BIOS settings, that was what was wrong with my computer when it happened to me.
if you need additional help, Google search: "black screen of death error"
also try chkdsk/f/r
if all else fails .. (=(FORMAT C:)=)
edit - also when you get that first 5 minutes, quickly open up command line and type in sfc/bootscan, then type sfc/scannow.
