So I tried to install a game demo, which finished then asked me if i wanted to restart the computer, so I did. When it starts up it says:

Windos failed to start. A recent hardware or software change may be the cause. To fix the problem:

1. Insert your Windows Installation disc and restart the computer
2. choose your language settings, then click Next
3. Click "repair your computer"

File: \Windows\System32\drivers\sfsync.02.sys

Status: 0xc0000428

Info: Windows cannot verify the difital signature for this file.

If I put in my Vista disc then it comes up with another screen asking If I want to run in Safe mode, run normally etc.

My keyboard won’t work on this screen so I can’t select anything!! What do I do? I really don’t want to have all my stuff wiped so please help…
I would try to do that but my keyboard won’t respond when the screen comes up, so I can’t select anything.

Brand new Asus model X83V. Had it for about 2 weeks. I turned it off (properly) and left it alone for about 2 hours. When I turned it back on "Windows boot Manager" came up with the following message;

"Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click Next.
3. Click "Repair your computer."

File: \Windows\system32\kdcom.dll
Status: 0xc0000098
Info: Windows failed to load because the kernal debugger DLL is missing, or corrupt"

I have not installed anything since 2 weeks ago. I do not have a Windows disc. I have a recovery disc, but if I run that I will lose my pictures. My pictures are super important to me. I would lose all the pictures from my daughters birthday, among other important pictures I just can’t lose! Please help!

Hi,
My computer was fine just the other day, but i started it up today and now it wont boot up! I get an error message ‘Windows failed to start. A recent hardware or software change might be the cause.
File : CLASSPNP.SYS
Status : 0xc0000221
Info : windows failed to start because a required file is missing, or corrupt.

I put my vista setup disc in, i ran ALL the things it told me to (system restore, windows memory diagnostic, system repair, command prompt) but still they all fail.
I dont want to lose ANY files, because i have been doing lots of work lately on the pc and saved lots of important documents, is there a way i can reinstall vista without losing any of my important work?

As far as the driver digital signatures, it crashes right after I see my screensaver and reads me this long error message.

a recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.
If you have a windows installation disc, insert the disc and restart your computer. Click "repair your computer," and then choose a recovery tool.
Otherwise, to start Windows so you can investigate further, press the ENTER key to display the boot menu, press F8 for Advanced Boot Options, and select Last Known Good. If you understand why the digital signature cannot be verified and want to start Windows without this file, temporarily disable driver signature enforcement.
Status: 0Xc0000428
Info: windows cannot verify the digital signature for this file.

Enter=Continue|Esc=Exit

What I’ve tried so far:
Safe Mode (won’t work)
System Repair (won’t work)
System Check Point (none created)
Okay, it let me in Windows, where do I go from here?

How can I figure out the problem now that I’m actually in Windows now?

I’m paranoid, I feel like any minute it’s about to boot me off and give me that dreaded all blue prompt screen again-lol

Hello there I have a Toshiba Satellite laptop running on a upgrade from windows XP to Windows Vista Premminum. I have been running this version for some time now and nothing has happend in which I can not fix myself.. I have recently come accross a problume that brings me up to Windows Boot Manager. I will read exactly what it says and how it says it.

Windows Boot Manager
Windows faild to start. A recent hardware of software change might be the cause. To fix the problume:

1. Insert your windows installation disk and restart your computer.
2. Choose your language settings, and then click "next"
3. Click "Repair your computer."

If you do not have this disk, Contact your system administrator or computer manufacturer for assistance.
File: \windows\SYSTEM32\Drivers\SSHRMD.SYS

Status: 0xc0000098

Info: Windows failed to load because a critical system driver is missing or corrupt.

Thats when it ends. Now I know it tells me how to fix it but I have a problume.. When it tells me a critical system driver is missing or corrupt… dosn’t that mean its hardware failure or something like that and even if I put the disk in if im having hardware failure it wont work…

Also im concerned with what might have caused this problume. I know before the crash. I had gone onto Trend Micro 2008 anti viruse and it said a few things about windows changes and said that they were high so I changed them back. So im thinking when I changed them thats what happend… I know I might not be making a whole lot of sence but yeah im kinda confussed I have never seen this before….

So guys if you can help me out I will offer alot of points for it and if it is possable to instant message me at Musiclvrkd
That is an aim account so if you want to email me at that too it would be much appreciated. I dont go on yahoo answeres so I am more likly to get my responce if you give it that way thanks very much
