Random BSOD! Is it caused by RAM, graphics card, or other hardware?

Hi all,

I have been having random BSOD, sometimes it happens several times a day or once every few days. All drivers are installed and updated, and my computer is free of virus. I am not sure if it is caused by RAM or graphics card.

There are 3 main bug codes: they are 0x000000d1, 0x00000050, and 0x0000007f. I don't know if all 3 errors are caused by the same issue or not.

Below are the dump files:

Bug Check String : DRIVER_IRQL_NOT_LESS_OR_EQUAL
Bug Check Code : 0x000000d1
Parameter 1 : 0x90a0f194
Parameter 2 : 0x00000002
Parameter 3 : 0x00000000
Parameter 4 : 0x90e0b113
Caused By Driver : dxgmms1.sys

Bug Check String : PAGE_FAULT_IN_NONPAGED_AREA
Bug Check Code : 0x00000050
Parameter 1 : 0xd9768824
Parameter 2 : 0x00000000
Parameter 3 : 0x90bb200d
Parameter 4 : 0x00000002
Caused By Driver : ntkrnlpa.exe

Bug Check String : UNEXPECTED_KERNEL_MODE_TRAP
Bug Check Code : 0x0000007f
Parameter 1 : 0x0000000d
Parameter 2 : 0x00000000
Parameter 3 : 0x00000000
Parameter 4 : 0x00000000
Caused By Driver : NETw5s32.sys

Specs of my computer:
HP Pavilion dv7t-1000; Windows 7; Intel Core 2 Duo CPU 2.80GHz; 2.0 GB RAM; Nvidia 9600M GT.

It would be nice if someone can figure out the cause of the random blue screen. Thank you so much!

  1. with laptop run cpu-z if there two dimms in the laptop. take the battery and power off the unit flip it over and check that both ram sticks are locked in. if they are pull one and run memtest86 on the laptop and run the laptop. if it fine swap the dimms. if one fails testing then you had bad ram. for power check the ac brick with a volt meter if you can also if the wires look bad look to ebay for a new cheap brick. also check that the power pin on the laptop not broken or lose.

    I have done memtest86 and checked that the ram sticks are locked in. Is there a way to tell the source of the error from the dump files (shown originally)?
  3. Is your computer a pre owned unit, if it was a PC desktop I would say it was you PSU! But if it's a laptop I don't know how that would work, there are some Administrator Tools to check integrity of your system, Memory and Hardware. If all fails I would consider reinstalling the operating system from OS installation software, or restore to factory settings, If you can take you computer as much as you can and give it a good cleaning check for dust and hover it all out.

    Also make sure everything is plugged in properly, basically unplug al your cables and plug them back in firmly!! not jking!
  4. Also check your paging file size, make sure you hard drive ain't full!
