Multiple BSODs, help analyzing DMP files

Hello, I was hoping someone here could help me out. I recently upgraded from XP 32 to Win7 64 and am now experiencing frequent blue screen crashes. There is no new hardware except for 4 GB of memory that was already slotted into place that is now accessible in 64 bit Win 7. Also since it was a clean OS installation I've installed a large amount of programs and drivers.

The error I keep getting is PAGE FAULT IN NONPAGED AREA. I've managed to figure out enough to install the Microsoft debugging tools and read through some of the minidumps but I know nothing about analyzing them properly. The best I can see is that different processes are crashing but all causing the same error.

Dump files are attached. I'd greatly appreciate any help I can get as this is driving me crazy.

Hi Norron

Welcome to SevenForums :)

Some of the other experts on site here will provide the specifics in relation to your minidump.
I did notice however that you had upgraded to 7 from XP.
Were you having any issues with XP prior to the upgrade?
The best recommendation when upgrading is to perform a clean installation as that ensures that any systemic faults/issues that were present in XP would not carry over to the new OS.
Recommend in the meantime that you do the following:

1. Search for and upgrade to the latest hardware drivers - graphics card, mobo, sound-card (if add-on card) etc. Be sure to search specifically for the Win7-compatible drivers if they are available.
2. Download memtest (Google is your friend) and run it to check whether it isn't your RAM that's causing the issue
3. Download the latest DirectX (Feb2010) from Microsoft website and install that (Total file size around 106MB)
4. Update your OS via windows update (optional but could come in handy in case there are new Microsoft drivers for your hardware)

Hope this helps and keep us posted on your progress

Regards

I am assuming you mean you did a clean install with format for you cant upgrade in place from 32 bit to 64.

these all had the same bugcheck (50) and all were related to memory and had a game running at the time.


That being said I would download a program called memtestx86, burn it to a cd, and run it for at least 5 passes to test the ram.

Usual causes: Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus, Device driver, NTFS corruption, BIOS

Thanks for the quick replies. And I did mean that it was a clean install from XP to Win 7. I forgot that Microsoft uses the word "upgrade" in that way.

I'll run a test on the RAM and report back.

Anytime thats what we are here for. Good Luck

Thanks Norron.
Re-read your post and what zigzag stated xp>7 64

Better take a break

Well I'm back and after 5 passes memtest found no errors with my ram. I'm not sure if there is a way to generate a report from the program so I didn't bother. The only thing I can think of now that is a common link is that steam is always running when it blue screens. The most frequent crashes happen when I'm attempting to play games through the steam desktop client but it's also crashed a couple of times from the desktop while steam was running in the background. But I don't really know and am just guessing. You guys are the experts here.

Not a gamer, so expert on steeam, not. It may be that steam is the common link. Can it be re-installed?

It can indeed. I'll give that a try.

Alright, I tried uninstalling and then reinstalling Steam and no dice. I got 3 more BSODs today within minutes of each other. The dump files are attached. At this point I'm beginning to think it might be better to just format and reinstall again, even if it means spending a whole day to do it. Any opinions? Would just formatting from the win 7 install disk be the best option or is there another route you'd recommend?
