BOSD about week after new video card

Well it does not appear the Nividia Driver is a fault, the error is pointing toward DirectX again:

Stop message 0x00000050 Descriptive text: PAGE_FAULT_IN_NONPAGED_AREA
Usual cause: Requested data is not found in memory. This might be caused by a printer driver or remote access driver.

PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced. This cannot be protected by try-except,it must be protected by a Probe. Typically the address is just plain bad or it is pointing at freed memory.

DirectX Graphics MMS

Attempt to update DirectX if it will allow you to do so, either by Windows updates or from the following link:

http://www.microsoft.com/en-gb/download/details.aspx?id=17431

If that fails try the Windows hotfix found here:

http://support.microsoft.com/kb/974431

There might be a possibility of bad memory.
Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an interrupt request level (IRQL) that is too high. This is usually caused by drivers using improper addresses.

The analysis was somewhat inconclusive for your latest crashes.

Run Driver Verifier to scan for any corrupted drivers which may be causing problems, this program works by running various stress tests on drivers, in order to produce a BSOD which will locate the driver; run for least 24 hours:

Driver Verifier - Enable and Disable

   Tip

Do this after you have carried out my other suggestions below as the test may cause lagging/slow computer

Please ensure you Reset GPU Tweak to run at factory default settings.
Any overclocking will cause the system to become less stable.

Uninstall SuperAntispyware from your system.

Please update your BIOS as it is outdated:

[BIOS Information (Type 0) - Length 24 - Handle 0000h]
Vendor American Megatrends Inc.
BIOS Version 0503
BIOS Starting Address Segment f000
BIOS Release Date 01/05/2010
BIOS ROM Size 100000

A newer stable version can be found here:

ASUSTeK Computer Inc. -Support- Drivers and Download M4A78LT-M LE

   Warning

Please follow the manufacturer's instructions carefully when updating the BIOS, as incorrectly updated, may render your computer unusable!!

What is your PSU Power rating?

Look forward to your reply

Hi,

From your GPU specs it seems your 500W PSU just meets above the minimum:
Attachment 261837
