When taxed, my pc crashes whatever program running or gives me a BSOD.

I recently acquired a video card so i had it installed in our family desktop and proceeded to attempt to play a few games. I've found that taxing the system at all causes the program in particular to crash. I looked around on the net and decided to run some tests on my hardware (the pc has been around a while) to get a better idea of what was causing the issues before i blamed my GPU. While running a prime95 torture test (about 5 minutes in) i got a BSOD. After rebooting, i tried again with similar results. Can anyone help me decipher what is causing this? I find it hard to believe that it is the graphics card, since its pretty new.

The results of the diagnostics run by the SF Diagnostic tool are attached.

Most of the recent bsods blame nvlddmkm.sys - nVidia Video drivers

Driver Reference Table - nvlddmkm.sys

Have a look for an updated driver for that and I also notice your nforce chipset drivers are pretty old (2009) so it would be worth trying to update those as well.

I have (since time of original post) uninstalled all graphics drivers ( i had used another nvidia card previously) and associated nvidia software and reinstalled fresh drivers. I believe i took off every nvidia driver other than those needed for onboard (nvidia) video. I no longer get "nvlddmkm.sys" bsods, but the stop error BSODs, caused by a 'hal.dll' still occur.

This PC is practically a frankenstein with differing RAM and mixed and matched parts so to some extent i expect the errors but i still would like to pinpoint their source.

With respect to the chipset drivers, I will look into it. The latest drivers on the asrock website for my board are 2 and a half years old though...

UncleSly,
Help us to help you:

Update your SevenForums System Specs
User CP (located on the top menu bar) |
Your Profile | Edit System Spec (left-hand column)

To gather info, use Speccy (my favorite) or SIW or System Info

In the System Manufacturer Block, enter:
Ø Manufacturer and Model OR Custom build.
Ø ADD the word laptop, desktop, netbook or tablet.
For example:
Toshiba Satellite L305D notebook.

Provide full windows version info, for example:
MS Windows 7 Ultimate SP1 64-bit

Use the “Other Info” block for Optical Reader,
Mouse, touchpad, wifi adapter, speakers, monitor, etc

Scroll down and click on SAVE CHANGES.

With Speccy, you can select with your mouse/touchpad info from the display
and paste that info into your specs.

SIW is a marvelous program, but the free version does not offer
this capability.

I need this info due to peculiarities in your dump files.

System Specs updated. As i said before, this machine is quite the Frankenstein.
Thanks for the replies btw :)
