I did a search, didn't find anything remotely like this, so I hope I'm not repeating a solved issue. If this is in the wrong forum, please mods, move it where it belongs.
Okay, system info:
Home built box, all components less than a year old
M4A79XTD EVO AMD 790X socket
AMD Phenom II X4 965 processor 3400 MHz
8 gig RAM
Seagate SATA 750 gig HDD (partitioned, C: is bootable drive)
Windows XP Professional, sp3, fully updated
Here's the history:
Yesterday I tried to boot the box and could never get onto the internet. Nothing had changed from when I shut down the evening before (that I was aware of). I checked everyone else on the network was fine, just me. The port on the router I was connected to was orange, so I checked the cable and the port on the router -- the cable was fine on a different port, and the port was fine with a different cable. So it wasn't the router.
Traced it back to my box, everything was good outside the box, so it had to be a software issue. Unloaded F-Secure 2011, and magically had access to the internet again.
Here is where my issues start. Like an idiot, rather than figure out what was wrong with F-Secure to send it off the tracks, I uninstalled it and loaded AVG 2013 antivirus. Went to install it, got a blue screen which directed me to reboot my system.
So I did, got the POST and BIOS screen, and then just a black screen. Went in search of a solution on the net using my laptop, and found this is a known issue with AVG 2013. Fortunately (I thought) AVG supplied a fix -- to boot my box off their recovery CD, then change the extensions on all AVG files in WINDOWS/system32/drivers from .sys to .bak
When I attempted to do this, their utility would not open the above folder on the C: drive so that I could do that; or rather, it would open it, but there was nothing in there even though supposedly there is over 45 meg of data in the file.
Did a little more research, tried booting into Safe Mode. No joy, boot stops at the same black screen. Did Enable Boot Logging, and that's how I found out it's hanging at the file KSecDD.sys
So. Anyone have an idea what to do to get my system back and to consign AVG 2013 to the fiery bowels of hell?
