My System Specs:

2GB DDR2 from crucial
2.8ghz Pentium D
ATI X850XT Card

I have ran a memtest for 8 hours and no errors. I have checked the HD and ran a checkdsk. I just reinstalled ATI drivers and it said Microsoft has them as unverified/signed.

Any ideas? Any additional info I should post. I am completely new to this.

0x0000007F: UNEXPECTED_KERNEL_MODE_TRAP
One of three types of problems occurred in kernel-mode: (1) Hardware failures. (2) Software problems. (3) A bound trap (i.e., a condition that the kernel is not allowed to have or intercept). Hardware failures are the most common cause and, of these, memory hardware failures are the most common.


We need your minidumps.

How to find and post your Minidump Files:

My Computer > C Drive > Windows Folder > Minidump Folder > Minidump Files.

It is these files that we need (not the folder). Attach to your next post the five most recent dumps. Notice the Manage Attachments button at the bottom when you go to post the next time. You can Zip up to five files per Zip; if you only have one or two you don’t need to zip them, just attach as is. Please do us a favor and don’t Zip each one individually.

Thank you. Sorry I didn't post the dumps, I am new to this process. Anyway. here they are.

Hey, no need to be sorry!

For some reason two of your minidumps were corrupted and thus unreadable.

The other three were all the same 0x7F error and all cited the driver RtHDAud.sys driver as the cause of your issues.

This is a Realteck High Definition Audio driver. if your system is pre-built then go to the manufacturer's website, find your PC model and update the audio drivers from them.

If you built this or someone else did go to your motherboard manufacture's website, find your exact motherboard and update the audio drivers from them.

Thanks. I will try that now and let you know!

So far so good! It was constantly restarting when I used youtube and or wow. Really hope I don't see this error again!

Good! Let us know if you get 24 hour stability.

Works great. No restarts, and runs smooth. Thank you!

Excellent! Glad to be of help and thanks for giving us an update. This adds to the pool of knowledge and is helpful for others.
