Morning and welcome to CF mathez31
Google is your friend, my friend, first link when googling with
KERNEL_DATA_INPAGE_ERROR
http://www.microsoft.com/technet/pro....mspx?mfr=true
Seems like a duff drive or memory may be your problem. Along with a possible virus or controller error.
My money would be on the drive. But first run your antivirus\spyware progs just to be clear its not a software fault.
To discount the drive you could move your swapfile to a different drive if it goes then its time to back-up and get a new one.
If its still doing it after moving the swapfile, you could try to borrow some memory from a mate to discount that possibility, and lastly if after the first 3 options have been tried its still happening try moving the IDE cable from primary to secondary and changing your boot options to boot from the C: drive off of the secondary IDE channel.
