Please help

Your error is 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA and is defined by auhma.org as:

Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card).

* Your rebooting sounds like the same issue I had when I had corrupted memory.

I am not saying this is your issue but I would certainly run memtest on your RAM.

1. Go to www.memtest.org and download the latest ISO version. It is free and perfectly safe.

2. Burn to a CD.

3. Place CD in your drive and reboot with CD in drive. The test will take over.

4. Let it run for a LONG time. The rule is a minimum of 7 Passes. There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.

5. If you have errors you have corrupted memory and it needs to be replaced.

6. Also, with errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test.

* Get back to us with your results. if this is the cause then it is easy to fix. If not let us know that as well.
