BSoD:

Stop 0x50, PAGE_FAULT_IN_NONPAGED_AREA

I'm not going to bore you with my history, since those threads apparently don't get answered.

Also, before my computer stopped booting, the printer spooler service wasn't working, and I used Microsoft's FixIt or something, and it supposedly ran successfully. (Spooler still didn't start). I couldn't boot after this.

Tried to do repair installation on Windows XP Pro that kept giving me 0x50 instantly on boot. The XP Boot Disc did its stuff for the repair install. Said 'part of installation complete, let comp reboot for part 2', or something like that.

It rebooted. Loaded XP for about 10 seconds (logo and loading bar). Same BSoD (0x50). Any ideas?

(I have a working parallel installation, all hardware is fine)

A. If you have more than one RAM module installed, try starting computer with one RAM stick at a time.

NOTE Keep in mind, the manual check listed above is always superior to the software check, listed below. DO NOT proceed with memtest, if you can go with option A

B. If you have only one RAM stick installed...
...run memtest...

1. Download - Pre-Compiled Bootable ISO (.zip)
2. Unzip downloaded memtest86+-2.11.iso.zip file.
3. Inside, you'll find memtest86+-2.11.iso file.
4. Download, and install ImgBurn: http://www.imgburn.com/
5. Insert blank CD into your CD drive.
6. Open ImgBurn, and click on Write image file to disc
7. Click on Browse for a file... icon:



8. Locate memtest86+-2.11.iso file, and click Open button.
9. Click on ImgBurn green arrow to start burning bootable memtest86 CD:



10. Once the CD is created, boot from it, and memtest will automatically start to run.

The running program will look something like this depending on the size and number of ram modules installed:




It's recommended to run 5-6 passes. Each pass contains very same 8 tests.

This will show the progress of the test. It can take a while. Be patient, or leave it running overnight.



The following image is the test results area:



The most important item here is the “errors” line. If you see ANY errors, even one, most likely, you have bad RAM.

I ran memtest for I think 4 passes, with 0 errors. I can try running it again, but my parallel installation seems to run fine...I guess I'll just leave it on overnight.

Do you have only one RAM stick?

[Timbydude2]

I have 2, I think...a 2GB and a 1GB.

Memtest ran for more than 20 hours with both sticks in (went to school), 26 passes and no errors...(I think I have good RAM)

I really don't have the time to open my computer...I chose option B, and doesn't it still work?

[Broni]

Well, I can't force you do things my way.
After all, it's your machine.
If you don't have time, I can't do it for you.
