Windows 7: BSOD 768_1 at random times

Windows 7 Home Premium SP1 Build 7601
BSOD 768_1 at random times

I get a blue screen every 5 or 10 minutes. It's always 768_1. After 2 attempts, I was able to paste the BSOD message into my post before it crashed. After a few more attempts I got the SF diagnostic tool downloaded so I could build a zip file and attach it. I wasn't sure I would ever get that far so I also attached a zip file of just the mini dump.

I went to "add or remove programs" to see if anything new has been installed lately and I found something. On 8/7/2013 these two programs were installed:

HP FW Update ED02
HP Update

The problem started today (8/10) so I think these are the programs which are causing my problem.

I tried to uninstall these programs, but it always crashes while attempting to create a restore point.
I tried to do a system restore, but it crashes while looking for the restore point.

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.
Locale ID: 1033
Additional information about the problem:
BCCode: 50
BCP1: FFFFF98121F826A0
BCP2: 0000000000000000
BCP3: FFFFF88001622E60
BCP4: 0000000000000005
OS Version: 6_1_7601
Service Pack: 1_0
Product: 768_1
Files that help describe the problem:

file WER-49296-0.sysdata.xml does not exist. I found other WER files, but not this one. I did find the dmp file, but I don't know how to analyze it.

I had a lot of trouble with this step. Windows crashed repeatedly while the download and install was in progress. I skipped ahead to other tasks and then came back to this one. Finally, I got it installed.

Use the System File Checker tool and Run Disk Check
Response: Done

Run Disk Check in Windows 7 for Bad Sectors & Errors
Response: Done. See attached log file.

I have not finished all the tasks yet, but windows has been up for over an hour now, so I'm not going to install any more stuff for a few days. Thanks so much for your help.

I installed the CPUID HWMONITOR software and ran it. All the temperatures and voltages are in the normal range. I have been working with the Microsoft Help Desk. I gave them permission to take over control of my laptop. I watched as they repeated several of the same steps you advised me to take. They also tried other things that were not on your list such as reloading drivers. Nothing seems to help. My problem has been escalated to level 2. The next step will be to re-install windows 7. The install disk should arrive on Wednesday.

I will keep you posted as the saga continues.

Clean install of Windows 7 SP1 did the trick. I'm very happy with Microsoft Support. It's the best $99 I ever spent. I was trying to avoid a reload of the OS, but in the final analysis there was now way around it. Thanks for all your help koolkat77.
