1. Cannot boot to safe mode.
2. No repair option given on your XP CD.
You didn't tell us much about your PC such as make and model but most HP, Sony and such machines NEVER have a repair feature. This is a choice the makers made since OS repair is time consuming and given you can't condense the instructions to a volume smaller than War and Peace it's best to just forget about it and have the owner reinstall the OS.
So at this point I would remove the hard disk, put in a new drive, install the OS then add the old drive as a slave so you can get to your files.
OK... I have Windows XP Home w/SP3. It is loaded on a 6 year old P4 desktop with 1GB RAM.
Everything was great Sunday evening when I was doing some simple browsing on the Internet and editing some MS Word documents. When I was finished, I turned off my monitor and let the computer go into sleep/standby mode as I let it run constantly. I have been doing this for years.
Monday morning I come back to the computer and there is a black screen; it refuses to wake up from sleep/standby. So I reboot. After the POST, I see the Windows splash screen briefly with the blue bar at the bottom. Shortly after I get a mouse pointer and an error message box "lsass.exe - Bad Image The application or dll C:\WINDOWS\system32\DNSAPI.dll is not a valid windows image. Please check this against your installation diskette."
Black screen. Movable mouse pointer. Nothing else.
Cannot boot to safe mode. Cannot restore to last bootable restore point.
I am running AVG free for my Antivirus with the latest updates.
I have seen other people with similar issues who have been able to get access to the Recovery Console to do a Windows repair or to at least get to a command prompt. Here's my catch, there is NO option on my recovery CD to do a Windows repair. I downloaded Bart PE a while back and made a bootable CD so that I could at least get to a command prompt and Windows Explorer for moving files around. I followed some advice and copied over the System, Sam, Software, Security, and Default files from the c:\windows\recovery directory but, of course, this didn't fix it.
What is incredible to me is how everything was working JUST FINE Sunday night and someway, somehow, my computer seems to have screwed itself in the middle of the night by itself without any intervention from me.
I see why some people give up Windows and go to Mac. Some of us don't have time for this.
So here I sit with a black screen and no access to my OS. Does anyone have any suggestions? I am convinced there is a way to fix this without reinstalling my OS.
I tried searching the Cnet forums already and I haven't stumbled on anyone with the same issue.
By the way, I have a laptop that I am typing this on so I do have alternate Internet access (thank God).
