Every time I open any program the pc freezes and gives the message that the program is not responding. Even task manager freezes up. The only way I can get out of it is by rebooting but now I keep getting the blue screen with the following messages...

STOP : 0x0000007E (0xC0000047, 0x8051D1B8, 0xF9CC19FC, 0xFG9CC1A4C)

and MULTIPLE IRP COMPLETE REQUESTS

I have done chkdsk. I can only get into windows by using a boot disk but that only works about 1 time out of 10. I don't know why this has suddenly started happening as I have made no changes.

Can you boot into Safe Mode? Did you see chkdsk fix anything?
Do you get the same behavior & errors every time you try to boot?
Try unplugging the computer from the main for a bit & try try again.

Have you tried a system restore? Or perhaps run sfc /scannow.

How do you feel about a Repair Install?

Otherwise I can only suggest looking at the event viewer & or:

Also view your Error Log via:
[1] Start Menu
[2] Help and Support
[3] Pick a Task
[4] Tools
[5] Advanced System Information
[6] View the Error Log

& or see if you have a new dump log.

Some error details fwtw:

A few kernel mode routines do, however, perform explicit argument validity checks, consistency tests within data structures, and so on. Most driver writers have encountered an example in IoCompleteRequest: If the same instance of the same IRP is passed to IoCompleteRequest more than once (without an IoCompletion routine having returned STATUS_MORE_PROCESSING_REQUIRED in between), the system will crash, and the blue screen will display the moderately informative message MULTIPLE_IRP_COMPLETE_REQUESTS. This happens because, under these circumstances, IoCompleteRequest calls KeBugCheckEx.

Bug Check 0x7E: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
The SYSTEM_THREAD_EXCEPTION_NOT_HANDLED bug check has a value of 0x0000007E. This indicates that a system thread generated an exception which the error handler did not catch.

0 0xC0000047 0x0000012a 0x012a0001 NT_STATUS_SEMAPHORE_LIMIT_EXCEEDED "Too many posts were made to a semaphore."

I did see one post attributing the above errors to a virus.

Could plugging my digicam card reader into the USB port instead of the ps2 one have caused this problem? That is the only change I have made and the problems started when I uploaded photos. It just happened again and bought up the doctor watson debugging thing. I haven't tried rebooting without the floppy disk yet but will try it tomorrow. I have backed up my data just incase it all goes wrong.

Sounds like you found some problem

Do you see anything coincidental in the various error viewers?

There was nothing specific in event viewer. I have just booted without the floppy and everything is ok now. I can't believe that a simple thing like that could cause all that trouble. Thanks Jephree.

Glad to know you are well Jaynee
