Out of nowhere I started getting this error.
A blue window appears with the message
KERNEL_DATA_INPAGE_ERROR

and loads of code.

Anyone what could be it?
I've searched on google but can't figure out what is wrong.
I have scanned the hard disks for virus.
No additional hardware installed.

This error appears intermittently once or twice in a day and most of time it happens when I try to load any page in Web Browser.

The only thing I did was to connect 2 routers to my system. Now I've taken one out.

Any help will be appreciated.

I think I got it working. I had 2 NIC cards which might have been causing problem. I have removed the one and server didn't crash since then.
I'm still observing though.
