I keep having these issues. here is the output. I've done a memcheck on all ram and chkdsk /r for my drive. no errors or bad sectors. no driver updates are available. PC is an aspire 8943g any ideas?

hi, can you post some pc specs here?Regards George www.supportweblog.com

sure windows version: Windows 7 Service Pack 1, 6.1, build: 7601 windows dir: C:\Windows CPU: GenuineIntel Intel(R) Core(TM) i7 CPU Q 740 @ 1.73GHz Intel586, level: 6 8 logical processors, active mask: 255 RAM: 4224184320 total VM: 2147352576, free: 1941102592

Found this entry on MSDN: Resolving a faulty hardware problem: If hardware has been added to the system recently, remove it to see if the error recurs. If existing hardware has failed, remove or replace the faulty component. You should run hardware diagnostics supplied by the system manufacturer. For details on these procedures, see the owner's manual for your computer. Resolving a faulty system service problem: Disable the service and confirm that this resolves the error. If so, contact the manufacturer of the system service about a possible update. If the error occurs during system startup, restart your computer, and press F8 at the character-mode menu that displays the operating system choices. At the resulting Windows Advanced Options menu, choose the Last Known Good Configuration option. This option is most effective when only one driver or service is added at a time. Resolving an antivirus software problem: Disable the program and confirm that this resolves the error. If it does, contact the manufacturer of the program about a possible update. Resolving a corrupted NTFS volume problem: Run Chkdsk /f /r to detect and repair disk errors. You must restart the system before the disk scan begins on a system partition. If the hard disk is SCSI, check for problems between the SCSI controller and the disk. Finally, check the System Log in Event Viewer for additional error messages that might help pinpoint the device or driver that is causing the error. Disabling memory caching of the BIOS might also resolve it." http://msdn.microsoft.com/en-us/library/ff559023%28v=vs.85%29.aspx John Wiley

I'm doing the ram checks and running chips one by one. I'll try the bios shadowing, but I don't see any hardware errors.

I am guessing you can have the system up for a time before the blue screen, Boot up into safe mode, and make sure your video card drivers are up to date, use the ones from Aspire's website support downloads, and your chipset drivers are up to date.-- :P Advice offered, If you need more help it is advised to seek the council and advice of paid professionals. The answer is always 42, or reboot.

Did you recently update video drivers, or put a new card in? Also here is a link directly from Microsoft and Blue Screen error protocol. I had this issue so understand the frustration. http://windows.microsoft.com/en-US/windows7/Resolving-stop-blue-screen-errors-in-Windows-7John Wiley

Is this a VM? or a real physical machine?-- :P Advice offered, If you need more help it is advised to seek the council and advice of paid professionals. The answer is always 42, or reboot.

Jason's input made me notice two of these dumps are Memory Management related. The settings could simply be wrong and need adjustment, usually 1.5x that of the total current installed amount of RAM, or let windows manage it. John Wiley
