Windows 7: Machine_Check_Exception - Stop 0x9c

Machine_Check_Exception - Stop 0x9c

I'm driving down the highway and I get a frantic call from my daughter.

She sat down to use this computer (my specs), opened Winamp. The usual play list was gone - there was only one entry. The day before I was listening to a streaming radio broadcast in Winamp. That stream was the entry that Winamp makes when you link from the radio station's website.

When she clicked on the "song" the computer crashed. She wrote down the bluescreen info:

Machine_Check_Exception
Stop 0x0000009c
Minidump zip attached.

Told her to hit reset. She said when the computer restarted it took a long time on a black screen. After that all is right and no further probs.

Never seen this error before. Does anyone have any ideas what may have happened?

Thanks.

She's not supposed to have this error if she's running Vista or Win7. This error was last seen in XP - but you will see it in some Vista/Win7 systems if there's a dual boot w/XP or some virus infections.

Info on it here: BSOD Index

I'd suggest trying a couple of these free, online scans to make sure nothing has corrupted her current protection: Malware (read the details at the link)

Other than that, it could be broken hardware or an incompatible piece of hardware or software.

Thanks for the dump report Usama.
She was using my computer (My System Specs below) running W7 64 bit.

I had her run AV and malware right away: clean.

It could very well be that Winamp Lite v5.572 is incompatible. The program loads funny on occasion, I believe due to issues with UAC. I should create an elevated shortcut for it, but it was just too low on the priority list.

My WAG (Wild Ass Guess): by clicking on the stream play in Winamp it initiated a process that required a browser to be running (it wasn't) and linked to the website feeding the stream and this caused a logic error?

My current thinking is that one time is an aberration, two times starts a pattern. So I plan to just keep an eye on it. Do you think that is wise?

Thanks for looking at this and for your help.

That's my thoughts. Everyone gets a BSOD every now and then, but it's not a big deal unless it starts becoming a real problem.

Besides, a single dmp can only tell so much.

If you suspect WinAmp, check it out here: http://www.microsoft.com/windows/com...namp&os=32-bit
It appears that the 32 bit is compatible - but something's up with the 64 bit version!

One of the most overlooked portions of the BSOD screen is where it says (most times):
"If this is the first time that you've seen this error - restart your computer.
If this screen appears again, follow these steps: . . . "

Now that is interesting! And it explains what I am seeing. I will be looking for the next upgrade.

Now that kind of talk is going to put a lot of repair shops out of business!
I've always preached about the amazing rejuvenating powers of the occasional restart. It amazes me to hear about people who never shut down for weeks!
