Windows 7: Black screen , twice in one week !

Black screen , twice in one week !


I've read about this black screen problem and I wonder if my experiance my offer some light on the problem I have had and aslo a friend has had.

Last week I had reason to copy a file from a back up drive thats in a usb enclosure, anyway my AV kaspersky flagged up a alert about there being a trojan in one of the folders, so I ran a full scan on the drive and kaspersky threw the file into quarenteen or what ever its called, to be sure, I also scanned the drive with the lastest maleware bytes, the scan also found something listed as a trojan tried to clean it and thne asked me ot reboot the pc, I did reboot and all I was left with was a black screen with a blinking prompt after it had ran through the bios.

Next encounter, a webpage online, kaspersy flagged up a warning about a java exploit so once again I ran a quick scan on the pc and again ran malware bytes, malware bytes found another problem and asked me to reboot, I did and once again I was left with a black screen with the flashing promt

In Both cases Windows repair could not fix it, the first time an attempt at repair took over 40 minutes but it still failed to boot up, not such a big deal for me as I have a install image I created off the pc and also a full working image on a partition for just this sort of problem.

Its just a pain that I dont have a record of the bug or trojan that was supposed to be on the pc according to the scans I did. I wonder does this point to a new piece of malware causing this or just a problem with malware and virus scanners ?

A similar thing happened to a friends pc, again after visiting a website his Av popped up a warning about an infection and again, malware bytes rebooted and he got a black screen too. This ones a bit more flakey as I wasnt there to see it and he cant remember what the infection was flagged up as, I am sure if this becomes a common issue then some one will know what it is.

Another issue and a fix, I use a samsung lcd monitor, windoes 7 runs it just fine with its own driver but once the driver is updated via windows update, booting up takes a long time, there is a thing at start up called Samsung panel manager, disabling this from start up seems to have solved the long boot up, not sure if its a conflict with windows, a conflict with either of the applications in the start up group that are, kaspersky, mpf server ( print server )

Win 7 Ultimate x64

My symtom is a bit different, randomly, at any point (surfing, watching movie, email, etc) I get a black screen and system reboots. My guess was to back off my memory timings (from 7-7-7-24 to 8-8-8-31) and, thus far, no more black screens. Win 7 Ulti 64-bit, max updated. If I get another I'll report here.

If there is one piece of software that had earned its keep its the imaging software I use
