During the boot proccess keep tapping f8 until the boot menu comes up and then choose "Safe mode" see if it boots into that.

Also what drivers or progs were installed lately?

Generally, this error is very bad as it means that one (or more) of the registry hiv files on the laptop disk are corrupt, and Windows cannot boot if one or more are corrupt. You may be able to get lucky and be able to boot with the "Last Known Good" F8 boot option, but if not, you'll be reinstalling Windows if you don't have a repair disc handy:

Likely that the RAM is bad, incompatible RAM was installed or a bad RAM slot.

I gotten STOP: 0x00000050 PAGE_FAULT_IN_NON_PAGED_AREA followed by REGISTRY_HIVE_FAILURE or REGISTRY_ERROR BSOD on an IBM PC300 GL before, because of a RAM issue.
