almost every time I start up my offline Windows XP desktop, I get an error message before I even log on


The error message says





The instruction 0x7c936686 referenced memory at 0x00000000. The memory could not be "read"


If I log on after this error message, after about 10 seconds, I will get a


The system is shutting down. Shutdown initiated by NT Systems/Authority


Followed by a 20 second timer. I googled the first error message but only unrelated results showed up in Google. I searched again with quotes and got "No results for" "searching without quotes" and the same unrelated results.


There seems to be no information regarding this error message.




It can take up to 20 times to get a working startup!


How do I fix this?

When you start the computer press and hold the F8 button. Select safe mode with command prompt. Press enter.


If the shutting down message appears, click on start, click on run, type into Run, shutdown /a


Click ok or press enter. You will need to do that before the 20 seconds finishes.


Type into Run, cmd, click ok or press enter.


Type into the command prompt, chkdsk


Press enter.


When the disk check has finished, if it tells you to use /f  type in chkdsk /f


if it tells you to use /r type in chkdsk /r


press enter, type in y, press enter, restart the computer. The disk check will run, after that the computer will restart.

Funny thing, this problem never occurs in safe mode.


I have already done check disks and the problem persists.
