Lenovo Desktop has been crashing, I suspect a bad ram slot

Hi all -- I've been browsing and this seems to be a place to get some expert help. I have 4-5 dump files (sorry, they are not mini, and about 285k in size)

BSOD errors range from 1e to "a"

Fair warning -- Lenovo has replaced the RAM (and is now passing memtest), and the harddrive, and I suspect the mobo is now tossing out errors.

May I post the actual dump files? Could it be one of the drivers for the integrated devices (sound, network) is killing me?

Or possibly the Nvidia 9800gt card that I installed after buying the PC? I feel like my only hope is to dive into these dump files.

Any and all help is completely appreciated!

I'd suggest posting all the dump files and let us massage them a bit to see what we can find.

No problem. Attached is another .RAR file containing all recent dumps. From what I recall, the crashes happened at very different times: gaming, streaming music in Firefox, and encoding video.

I'll go into the machine specs part of my profile and add a lot more detail if it helps. Thank you so much!

We need the actual DMP file created when the computer crashed. Use these to find and upload them. https://www.sevenforums.com/crash-loc...d-problem.html

If the files are too large you can upload them to a service like rapidshare and put a link in the post.


thanks

Hi Ken -- please see post #5 above. I uploaded a .rar of several dump files. There are (6) in total.

Ugh, my bad. Not enough coffee this morning.

These were casued by several things. Memory corruption, the USB hub, and others

Lets start with the memory.. Download memtestx86, burn it to cd, and run it for at least 5 passes.

Let us know if you need help

Ken -- I really appreciate this.

I have gone down the memtest road (tested for 4+ hours). I originally got tens of thousands of errors. I called Lenovo and they sent me new RAM. Only 2 of the sticks now work and pass memtest.

When I try to plug in the 3rd memory stick, the computer hangs at a blank screen.

Is this possibly a bad motherboard?
