BSOD NO Dump File

I've had trouble with BSODS and screen freezes on and of for a couple of weeks. Sometimes there is no dumpfile and sometimes there is nothing in event viewer. I uninstalled Avast free and the problem was gone for 4 days. I've tried almost everything. Cleaning out dust updating drivers sfc scannow/ diskcheck. I also reinstalled an image from before the problems started I had another this morning but no log I attacked what I've found relating to it. This is a Windows 7 64 bit with 8 gig ram and a NVIDIA GT 9800 video card. It's a HP dt500.

Hey Joe:
Good to hear from you again, it's been awhile. Wish it could be under better circumstances. Would you please;
First make sure your machine is configured properly to facilitate the collection of .dmp files.

Go to Start and type in sysdm.cpl and press Enter
Click on the Advanced tab
Click on the Startup and Recovery Settings button
Ensure that Automatically restart is unchecked
Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box
Ensure that the Small Dump Directory is listed as %systemroot%\Minidump << where your .dmp files can be
found later.
Click OK twice to exit the dialogs, then reboot for the changes to take effect.

Then:
Please read the first post in this sticky thread here How to ask for help with a BSOD problem
Do your best to accumulate the data required.
Run the SF Diagnostic tool (download and right click the executable and choose run as administrator)
Download and run CPUz. Use the Windows snipping tool to gather images from all tabs including all slots populated with memory under the SPD tab.
Likewise RAMMon. Export the html report, put everything into a desktop folder that you've created for this purpose, zip it up and attach it to your next post (right click it and choose send to, compressed (zipped) folder.
If you can do this we'll have a look and see if we can help find the culprit.

Thanks It is enabled and sometimes it creates a mini dump and other times not. I did just find the memory dump file from then. I'll check and see what I can find. Most of these have seemed to come 15-20 min after an anitvirus update while I am using firefox. I thought getting rid of Avast took care of the problem until this morning.
Joe

What did you replace Avast with?
Generally in the interest of BSOD peace of mind, we recommend MSE from here Spyware Protection | Free Spyware Protection | Microsoft Security Essentials seems to be BSOD friendly, a decent product, small footprint overall and free for personal use for up to 10 computers.

I went with AVG I used it before. It's frustrating the way they keep updating security software and try and make a complete package and ruin good products in the process. If the problem continues I may try the MS program. I wasn't that impressed with it in Windows 8. I like it to auto update and give a notification. I'm getting ready to go through the steps in your earlier post. The only hardware I've added was an internal drive late last year. I did replace the video card 2 years ago. I bad driver messed up the old one. Over the winter I pulled the heat sink and redid the thermal paste. I just put it away as a spare. I just noticed the memory dump setting got changed to kernal dump so I changed it back to small minidump.

Sorry for the late reply. Jury duty today and just got back.
Agreed, some AV products can be a bit over zealous and actually cause some aggravation as well as in some rare instances BSODs. We've seen that a bit with Norton, McAfee as well as AVG. I suspect that is generally an issue with remnants left over from old products and or corrupted installations of newer products but it does happen.
I suspect that is at least one of the reasons why the top tier AV manufacturers all have their own vendor specific proprietary removal tools.
AVG | Download tools and utilities
https://www-secure.symantec.com/nort...=english&ct=us
How to uninstall or reinstall supported McAfee products using the Consumer Products Removal tool (MCPR)
and there are lists like this one Security Software | SingularLabs that provide some help with locating uninstallers.
When you get around to collecting the data referenced in my earlier post. Zip it up and attach it here and we'll have a look.

I got more BSODs today and rebooted and got another before I could find anything. I got one this afternoon and rebooted and ran checkdisk with repair checked and it appeared OK. That first one today I was in Firefox. Now I'm beginning to get them when I boot into safe mode I can't even get much of a peek at dump file with Who Crashed. One BSOD mentioned NTOSKRNL.EXE The last one had IRQL not less or equal. Do you think it's a hardware error? Would a repair install work? I hate to go thru reinstall or reimage if it's a hardware issue. What's frustrating is after I took off Avast and added the AVG it worked for 4 days. I've got an image from just after the July MS updates when everything was OK. I have a few earlier on more than one drive. I was wondering about ram or the video card
Thanks for your help.

Actually it sounds suspiciously like a possible infection. So..... try running an offline scanner, this one will help you make a bootable CD What is Windows Defender Offline&#63; (get the right version for your architecture) boot from the CD and run a full scan. Program defaults to quick scan so change it to full and run the scan.
You can also check your memory offline and independent of your OS

Download Memtest86+ from this location here. Burn the ISO to a CD and boot the computer from the CD from a cold boot after leaving it off for an hour or more.
Ideally let it run for at least 7 passes / 6-8 hours. If errors appear before that you can stop that particular test. Any time Memtest86+ reports errors, it can be either bad RAM or a bad Mobo slot. Perform the test RAM sticks individually as well as all possible combinations. When you find a good one then test it in all slots. Post back with the results.
See this Guide to using Memtest 86+

I'd really like to see the contents of C:\Windows\minidump
you could possibly boot to a Live CD a Linux Distro and copy it off that way, if you can't even boot into safemode, then a inplace repair might be an option How to Perform an In-Place Upgrade on Windows Vista, Windows 7, Windows Server 2008 & Windows Server 2008 R2 and if you have Sp1 installed you will likely need to get the install media you need from here Download Windows 7 Integrated With SP1 ISO – Official Direct Download Links
But you'll likely have problems as it requires you to be booted into Windows in order to start such a repair.
Just throwing ideas out there. Without the dump files it's difficult to say with any degree of accuracy and even with the dump files, if it's crashing early on in the boot process there may not be a lot to see.

I had A UBCD 4 Windows and retrieved 3 dumps I'll attach them. It only showed 4 gigs or ram in specs then I realized it was probably a 32 bit setup. I ran the MS Stand Alone sweeper and it didn't turn up anything. I ran startup repair 3 times it didn't find anything. The MS memory test is going now. I'll do the Mem Test as soon as I can.
Thanks alot

Im not a pro at dmp debugging, but you're bsod's are all over the place. By what i know this can mean a virus or a faulty MOBO.

csrss.exe was mentioned in one, this is a vital runtime process. A virus could be disturbing windows processes. Try using McAfee &ndash; Computer Anti-Virus Software and Internet Security For Your PC (this is a link to Stinger) as it is very good for picking up nasty infections.
