Maybe you should upgrade your power supply.

YOu do need a new psu.   They're isnt enough power to run everything and refresh the dram on the card giving you the memory errors

Looks like I found a new home for this brand new 400 watt PSU I have sitting here taking up space.

Thanks for the input guys. After the RAM upgrade,CPU upgrade and GFX card I suspected the power supply just wasn't up to the task.  I hope this takes care of it.

If the card requires 300 and you've only got 250, you should probably get 400, at least.

I'm sorry, this question kinda feels like asking why the air condition doesn't work in my car - I mean, sure, I've got a huge hole in my roof, but surely it can't be the issue?

New PSU. Get one.

Edit: 196.21 are the latest ones, since they apparently discovered a problem with the previously latest ones. I even had to downgrade, so yeah, I remember that.

No.  But thanks Narbytrout.

Where is Yrag?

Have you ever tried to overclock you pc?  If so, try using all of the default setting on your voltages.  If you have not ever overclocked your pc try raising your MCP, FSB, and RAM voltages "one notch".

Another thing to try is disabling the "IPHelper" service by going into System and Security - Administrative tools - Services.  While you are inside the services page there are other unnecessary programs you can disable or set to manual - here is a LINK to a very simple guide to follow.

Yet another thing to check is... Is your power management (sleep, hibernation, etc.). If you need to manually re-enable hibernation do this:

1) Run the command prompt as administrator (it's under Accessories, right click and "Run as Administator".

2) Type the following: power -h on.

I hope this helps, I know how much of a pain it is to agonize over these issues for nights on end.

Also, I must say, Wiz's gift of a 400W PSU did increase my WEI score, I still crashed after that, so I am still looking for other causes/solutions.

Same here. The video card on my laptop overheated and fried the motherboard in the process, thanks to some poor designs on HP's and Nvidia's parts. I had about 2 weeks of this error, then it died completely.

So good luck. I hope you don't have the same problem I had, and you can get it figured out.

Me too! Thanks Tom!!!!

I'll get work on Aztec.

Drives.

I had the same thing with my nVidia. It took about 2 months for an update to them to be published and it stopped.

nVidia sound drivers???  I did not even know they made a sound card.
