Machine types 00000000 continuously when I start to type.

Regardless of what software my computer types a series of zeros when I start to type as if the zero key is depressed conttinuously. I have returned computer to facory settings and changed keyboard all to no avail. I am running Windows Vista Home 32 bit. It is maddening - can you help?

Sounds suspiciously like a stuck key.

I am presuming this is a desktop PC. Turn the PC off and unplug the keyboard. Turn the keyboard upside down and give it a shake; you may well see dust/muck fall out.

Plug the keyboard back in and then boot the PC. Do not touch any keys on the keyboard. Select the on-screen keyboard (Start/All Programs/Accessories/Ease of Access/On-Screen Keyboard) and try typing with this - it should type without the problem. Try the keyboard again and see if it works correctly; if it doesn't you will need to replace it.

No this is not the answer - the same problem is still happening with a brand new keyboard bought specially for the purpose

Is it only zeroes and does it occur with all programs?

  Eileanbeag 14:58 11 Mar 12

Yes - it happens in web addresses, and also word and any typing

We attempted to do a CHKDSK and also sfc/scannow but neither would work; a black screen flashed on very briefly and that was it

Very odd as you've done the obvious things like changing keyboard and restoring pc. Is it a USB keyboard? Try a different port. This shouldn't make a difference but sometimes a USB port can play up.

Do the zeroes stop?

Beginning to suspect hardware failure.

When you search for CMD in the search box, then right click CMD in the list and run as administrator. Type sfc /scannow noting the space between 'c' and '/'.

If you have a ps/2 connected keyboard then try a usb one or vice versa. Sure you could borrow one just to try. Depends if you have a ps/2 connection though.

Have changed usb and keyboard now works fine thanks for your help. Ran sfc /scannow and had the following result - how do I fix this and what does it mean?

Windows Resource Protection found corrupt files but was unable to fix some of th em. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log

C:\Windows\system32> Got as far as finding C:\Windows:\Logs\CBS and could not find the next part of the file. Did try to paste into Search and got Access denied. I can live with this but just wondered what files were corrupt and how they affect Windows

Eileanbeag - sounds like the '8 Duck Eggs' virus....only joking!

It's good you have control back, on your machine.
