BSOD that changed resolution and restarted computer

[Emelin]

Saturday (3/16/13) and today (3/19/13) my laptop crashed with a blue screen that was much smaller than the screen. The first time, I was on Facebook on Chrome and the second time, I was playing Minecraft. I didn't notice any changes the first time before it happened, but when I was playing Minecraft, it started hanging for a couple of minutes before it blue screened. The error message stays on screen for about 10 seconds and then the laptop restarts itself.

I'm not extremely tech savvy so I can't really provide many details. I do know enough to find needed information if I'm given steps and I do have Speccy to find additional information. Attached is the SF Diagnostic Tool information for today's crash. The dump file for Saturday's crash was accidentally deleted by CCleaner.

Please and thank you!

Welcome to Seven Forums.

Seeing the usual causes of this error code, it is usually hard to diagnose.

STOP 0x0000007F: UNEXPECTED_KERNEL_MODE_TRAP  http://carrona.org/bsodindx.html#0x0000007F

Usual causes:  Memory corruption, Hardware (memory in particular), Overclocking failure, Installing a faulty or mismatched hardware (especially memory) or a failure after installing it, 3rd party firewall, Device drivers, SCSI/network/BIOS updates needed, Improperly seated cards, Incompatible storage devices, Overclocking, Virus scanner, Backup tool, Bad motherboard, Missing Service Pack

We start with the basics:

Perform a clean install of your ATI driver:

Driver	c:\windows\system32\drivers\atikmpag.sys (8.14.1.6099, 184.50 KB (188,928 bytes), 4/16/2010 9:11 AM)

Sometimes drivers remain, not completely uninstalled. Follow this tutorial for complete removal of drivers of the particular program:

​

AVG can be a contributor to BSOD's. Please remove it using its removal tool from here: Uninstallers (removal tools) for common antivirus software - ESET Knowledgebase

Start Menu\Programs\AVG	Public:Start Menu\Programs\AVG	Public

We recommended Microsoft Security Essentials from a strict BSOD perspective. Is most compatible & provides most stability compared to other antivirus app/Internet Security Software.

• Microsoft Security Essentials, Free antivirus for windows
• Malwarebytes Anti-Malware Free
• Good and Free system security combination

   Warning

Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

Run a full scan with both (separately) once downloaded, installed and updated.

Please uninstall DAEMON Tools and any Alcohol % software. It uses a driver called sptd.sys which is known to cause BSODs in Windows 7. Uninstall the software using Add/Remove Programs. Reboot the system. Once the program is uninstalled, run sptd.sys uninstaller to remove the driver from your system.

As an alternative, many people recommend the use of Total Mounter or Magic ISO

We do not recommend 3rd party defragging programs. Please uninstall:
