video crashing TP video memory failed on T43P

[newmanm]

my video has been crashing.

I tried rolling back drivers to no avail and then decided to see what pc-doctor said.

pc-doctor says failed video test.
engine (1) test failed. pcdr2d3video module
PCDr2D3DVideo (805) Error at pixel (2,0): Input color if not equal to output color 7f. Display Mode: 640x480x8

is this fixable?

Try running this and report back:

Is this the driver that you're running?

at the moment I am running the original driver. I took out my harddrive and reinstalled the system on the original drive, so I am running the driver from 2005.

I can't get the newest driver to install.

I was running the 2009 driver before the system started crashing. both drivers cause the system to crash.

the error message from above was from running in safe mode.

I am now running in regular mode and the test has a mesh ball turning.

Just let it run...for hours...

I updated pc-doctor. it was touch and go to get the older version un-installed and the newest version installed because of system crashes.

the newest version shows the video memory to be ok. I don't know if video memory is shared, so I took out the extra 1GB of memory I had in the machine prior to the latest series of crashes.

as I typed the above, I just now got a new error message: *** Hardware Malfunction call your hardware vendor for support NMI: Parity Check / Memory Parity Error *** The system has halted ***

That's a regular RAM error.
The T43p has dedicated VideoRam in the ATI-GPU, not shared.

thanks. I will check it out.

based on the above hardware tip as regards to the hardware failure, I have swapped out the main memory module and will see if that solves the problem.

the newest ati driver now installs. no crashes so far. I am also not getting a weird bluish hatching on the video i was getting previously.

a bad memory module seems to have been the problem.
