Computer crashed & will not let me in (not even in safe mode)

[AdrianW]

I think I have a big problem here but I'm hoping someone might have a solution..

I've had similar problems in the past. Not that frequent and a reboot is all I need to keep going.

I was using firefox, My Avast warned me of a threat, I 'moved to vault'. This kept repeating 4 or 5 times.

Error messages were popping up and I was closing them.

I closed as many tabs as possible.

All seemed to be OK and then a balloon pops up warning me that Windows firewall is inactive. I activated it - but I don't think I should as it's not usually on.

Then a minute or so later the computer crashed.

I try to start in safe mode but 'a problem has been detected and windows has been shut down to protect my computer'

I get this -

0x0000007E (0xF789E508, 0xF789E204, 0xF789E508, 0xF789E1BC)

or the same but with these as the last 2 groups - 0xF789E4C0, 0xF789E1BC

Can anyone please help me here?

I just had this same error code (7e) with a friends machine. The only way that I could fix it was doing a windows repair install.

Things I tried that didn't work.

1) Using BartPE to restore registry - restored fine but still no boot.

2) replacing recently changed files in system32 with originals

3) Using BartPE to scan and clean drive - scanned and cleaned but no boot

I'm sure this is not the only way to fix this - but it worked for me. You will need to re-activate windows after the repair.

Hi mastershake,

A repair install may well make the computer bootable again, but there are other things to be considered beforehand. Firstly, in certain computer configurations, a repair install will completely overwrite the My Documents folder, thereby destroying any data that was contained within it. I know this for a fact because some years ago I made this mistake twice before I learned better. And secondly, you never know what's actually going to happen if you do a repair install with malware, especially rootkits, still present on the computer. It's even possible that you could render a Windows installation unrepairable by doing this. Although, admittedly, it is unlikely. The correct procedure here, for non-technical users, would be to use a boot cd to back up the My Documents folder and any other important data; and then run a full virus/malware scan to remove as much of the infection as possible before running a repair install. A PC Technician may try other things first before running a repair install, but I won't go into that here.

The reason I referred the user to the Malware Removal - HijackThis Logs, instead of advising him myself, was because malware removal advice is only allowed to be given in that particular forum.
