[Bolvua]

Hello Guys.
I have this problem a few days. I tried a lot of thinks what I found on internet but nothing works,
I m really tired. Please help me. I need my computer back, because I have a lot programs in there.

I think that this problem started when I connect second monitor in HDMI. Is it possible?
I have AMD/ATI HD5670.

Full sub.

Does it not boot to windows at all? If so, try http://www.sevenforums.com/tutorials/666-advanced-boot-options.html > Last Know Good Configuration (advanced). Does it boot now?

Yes, any change in the configuration may cause it.

Sometimes this issue may occur during running the computer and the user can boot to windows back. If so, post it following the Blue Screen of Death (BSOD) Posting Instructions.

Not working

We are still in dark at the very basic.

Does the BSOD happen during boot and makes the system unbootable at all? Or does the BSOD happen during running the computer?

Not working is not a reply to get any information from; and system restore was not suggested.

So the BSOD happen during boot and makes the system unbootable. I tried safe mode and also BSOD.

Sorry for my low english.
