Microsoft Windows 7 Professional 64-bit 7601 Multiprocessor Free Service Pack 1

Yeah, just got a BSOD. It ran fine last night/this morning. I'm gonna return the RAM I think for just 2 sticks of 8GB instead of 4x 4gb that I'm using since it's been suggested that 4 sticks and the AMD don't get along.

It gave me another 0xA (IRQL_Not_less_or_equal). If you want, I can toss up the Log (via the jcgriff tool) if you wanna give it a look.

Sure, the more the better. Actually, all you have to do is zip up the C:\Windows\Minidump folder and upload that.

Well here they are. All of the logs I have basically lol. The 0408 of course being the one I got smacked by today.

Just on a side note...I'm an idiot. I did what the g.skill forums said to do with the whole AMD issues thing, but the suggestion I used was for NON-Black Edt. processors. Mine happens to be a black edt. So I went ahead and fixed that and will be trying it out tonight. I'll report back.

Another STOP 0xA error.
Run Driver Verifier again - just to rule out 3rd party drivers (using these instructions: Driver Verifier Settings )

Update or remove program related to hamachi.sys (it dates from 2009)
More info on the driver here: Driver Reference Table - hamachi.sys

Update or remove program related to PxHlpa64.sys (it dates from 2009 also). It's related to a CD/DVD program on your system.

Further info on BSOD error messages available at:

Microsoft Windows 7 Professional 64-bit 7601 Multiprocessor Free Service Pack 1

Just wanted to update this thread.

As of right now, no BSOD/Random restarts since the last time I reported it. Doing the proper procedures off of G.skill's forum for this issue (AMD/RAM not getting along)- Found here: AMD CPU + G.Skill DDR3-1600 - GSKILL TECH FORUM is what seems to be "working"

I'm knocking on wood, cause the last 2 times I thought it was "fixed" and said something about it, within a few hours it would Reboot/Freeze/BSOD.

As far as trying to update those drivers USASMA, I couldn't do anything for Hamachi. It's part of their software so I just removed it.

As far as the PxHlpa64. I'm not sure which CD/DVD program it is. I didn't install a program on here for it when I built the machine. I goggled it and it seems to be for almost any cd/dvd program so I'm kind of at a loss.

Thanks for all the help though usasma. I appreciate the time/effort you put in the help me (and many others) out when we are pulling our hair out.

Don't worry about the PxHlpa64.sys driver. I've only seen it be at fault once in all the years that I've been doing this.
I'm avidly following this topic because of the AMD vs RAM problems that you've noticed (and have researched).

Good Luck!

Welp. I thought the problem was resolved and I guess I was wrong. A few BSOD here and there with the same errors basically. Got a new one today though blaming dxgmms1.sys for the crash (DirectX)

Want me to toss up the mini-dump usasma and take a look at it?

Microsoft Windows 7 Professional 64-bit 7601 Multiprocessor Free Service Pack 1

I know this thread is old but I am once again having issues and in similar fashion. BSOD's while gaming.

The only thing that has changed since the last post was that I found out the Phenom's II processors had issues handing high amounts of RAM due to the Memory Controller (G.Skill has a fourm/post all about it). I did what they suggested and the BSOD's went away.

Since then is I did upgrade my processor so it could better handle the 16GB of RAM. I went to a AMD FX-6100 6-core processor (3.30ghz)

I'm thinking that this might not be a RAM issue this time but possibly a graphics card issue (getting BSOD's due to a nvidia kernel error it seems). I don't want to jump to conclusions though, go get a new card and then keep having the same issue.

If someone doesn't mind taking a look, it'd be appreciated.
I've attached the zip from the SF-Diag tool.

EDIT: Forgot to add--If I play a game like League of Legends all that happens is I get 3-4 seconds black screen/freeze then the game comes back up (sometimes mass FPS drop for a bit). But if I play a game like Path Of Exile or World of Warplanes it BSOD's with either the Nvidia error or the IRQL_Less error. Not sure if that helps. Also go the BSOD due to an aftermarket screen save I downloaded.

Hi, recently I've been having rather frequent (at least twice a week) blue screens. I wouldn't be able to tell you when they started, however, since previously they weren't such a big deal.
