Error code 1000008e, parameter1 c0000005, parameter2 f4c42c86, parameter3 f8787cb0, parameter4 00000000.


each thime the parameter2 and 3 have different value.

Any Ideas.
Have re-installed all drivers.

Run a memory diagnostics tool like Mem Test 86 ( http://www.memtest86.com/ ) and make sure you ram is functioning properly.

Also do any strange errors show up in your even log?

Any unusual noises coming from your computer?

The error is register in the event log.

I will try the mem test and report back
