It could be very bad, but most likely it is a virus that is hiding you Operating System. This is where the Ultimate Boot CD for Windows would come in handy. If it is a virus, you could boot with that and clean it easily. Let me know how it goes. :tazz:

Actually it dosnt sound like a virus it sounds more like a OS Troubleshooting.

Did anything unusual happen before the first encounter of this ?

Which OS Do You Have Running ? XP Pro or Home ed.

How Long have you been using your computer ?

Please Answer Carefully Im Sure We Can Get This Sorted.

Please Let Us Know :tazz:

ComputerWiz viruses dont usually make this come up they usually infect in other ways.

Usually is the key word. I don't know if a virus will make it display that particular message, but I've had a customer with a similar problem. Their computer said "Invalid system disk, please replace disk and then restart" or something like that. They didn't have a floppy in the drive, and they didn't have a CD in. The only media present was their hard drive. I used the Ultimate Boot CD for Windows to delete 24 viruses. The computer worked fine after that.

I'll let you handle this your way, but if it doesn't work, consider what I said. :tazz:

Have the same error on my comp at home, but I know what I did... :)

Kinda fubared my MBR... :tazz:
Good thing I've got a UBCD so I can just Grub my way in...
I even installed LILO, but it still gives me the "missing operating system" garbage... which was an improvement from the original "invalid partition table"... heh...

MBR - Master Boot Record. Necessary to boot computer. Software I think.

UBCD - Ultimate Boot CD for Windows. Get it from www.ubcd4win.com

LILO - I don't know

As odd as it sounds...I restarted once more and what happened was Windows scanned everyting one more time and message was that my Kodak EasyShare software was corrupted. And in msconfig it is on startup. So I am assuming now when system dealt with Kodak and I've removed it from startup...can I hope for the better? THANKS

Letting you know that yesterday I had purchased and installed new antivirus software, it scanned a whole system and haven't found anything wrong with it.
So I spent whole day yesterday and half-a-day today working. Then shut down and when I came back it was giving me a blnk monitor screen with a cursor shivering at the top. What is up? HELP!

Hi all
Try restarting and as soon as the computer boots start tapping F8
doew this give you the option for either safe mode or last known good configuration?
if yes try last good config, if that does not work then try safe mode.
