Regular BSOD for past week, multiple probable causes

BDH · 20 Apr 2015

Hello, I've been on a bit of a journey the past week so I'll try to be brief and organized.

Last Tuesday, I added 2x4 GB of new RAM (same make, manufacturer, GBs, speed, etc. as the old RAM) and hooked up a second monitor (same as old monitor, though due to my GPU's available outputs the old one is on hdmi and the new one is DVI). Since then I have been having regular BSOD crashes, typically after 3-4 hours of consecutive use though on Sunday it managed to go 7 hours without crashing. I have had seven BSOD in the past week. There appears to be no common program causing them, I'll just be watching a movie, playing a game, or doing some typing when the crash will just happen.

For quick reference, the probable causes for each BSOD are listed in the minidumps as follows (from oldest to newest, I only thought to record the Stop data for the two most recent):

dxgmms1.sys
win32k.sys
HDAudBus.sys
ntkrnlmp.exe
atikmdag.sys
tcpip.sys Stop oxoooooo7F
hardware/dxgmms1.sys Stop oxoooooo3D (the minidump listed hardware, the actual BSOD showed dxgmms1.sys as the cause)

Trying to figure things out for myself, I first tried removing the second monitor after the second crash. When that had no effect, I tried updating my GPU's drivers through AMD Catalyst Control Center. Then I ran memtest86 for 10 passes with no errors (I've included a screenshot).

At this point I'm guessing it's a driver problem or something wrong with my GPU, since several of the minidumps seem to point graphics being the issue, but I've never had this much trouble with a computer and I wanted to get some more experienced guidance before I go any further.

Thank you, I appreciate any and all advice on this issue.

There is a saying about using RAM ....

If you're going to upgrade RAM in future you'll want to replace the whole lot anyway so it doesn't matter. Always use RAM in kits, never mix and match even if it's the same brand and the same model.

So I would suggest you to remove the additional RAM and see if the BSODs continue or not.

Let us know.
