I have been an Avast user for 5 or 6 years now and prefer Avast! over any other anti-virus program out there. I recently built a new AMD quad-core system with 4GB ram and fresh install of Windows 7 Home Premium and have been experiencing BSOD crashes. I did some reading and uninstalled everything possible that could be causing the problem and then I uninstalled Avast! and no more BSOD crashes. Every time I did crash, it would be from browsing the internet with Firefox or doing something that Avast! needed to scan on-the-fly. Each crash, I looked in BlueScreenView to see what the cause was and it would be random from ntoskrnl.exe to win32k.sys or Ntfs.sys and so on.
I have pretty much ruled out hardware failure due to running Memtest86+ v4.10 for 10 hours in each dimm slot, ran hard drive tests for possible bad sectors… you name it… I have done it.
I don’t have Avast! installed right now but if you need a minidump to further investigate my problem, I would be willing to reinstall Avast!.
Also, on a side note, Avast! 4.8 BSOD crashes me as well.
Hello, I’m curious to see some your minidumps, could you please send me a couple of the latest minidumps (from \Windows\minidump folder) to kurtin@avast.com? Thanks.
May I ask some help from Avast v.5 on Windows 7: I tried to open a Picture folder on my HDD drive E…the moment I click on Avatars folder where I keep my foto ID’s a False alert message appeared and put my Avatars folder on the Virus Chest…I want to recover many times but still keep on hiding and hiding the Avatars folder in the Virus Chest…then I read an instruction to make a different name folder on a different dirve C so I’ve transferred all my foto album collections on a new fold after clicking one of my foto on a new folder all the foto subfolders are empty…I lost all my 1 year collection of videos & fotos…please help me to recover them all…I uncheck all the FALSE SYSTEM SHIELD settings in my Avast 5
I have been running basically the same system that I built back in December with Avast and no problems at all. I am using Windows 7 Home Premium 64 bit.
Wolfman86, looking at your dumps it seems quite strange, so:
062710-24554-01.dmp, system (win7 x86) crashed (memory fault), but avast wasn’t even installed; have you tested both computers with memtest86+? since it seems like a hw problem here (are all your memories modules running on the same frequency, etc?)
062710-20186-01.dmp, system (win7 x64) crashed in our driver (memory fault), but that chunk of memory, it was tried to read, was valid - although the system crashed…
btw, win32k.sys crashes are quite rare and they’re not usually caused by applications/other drivers…
I have been stable running Windows 7 64-bit without avast installed for 36 hours now. I will install the newly updated 5.0.594 version of avast and see if I still crash. I will send you the dump file if I crash.
Hi Wolfman86. Please do update us on the 5.0.594. Would love to know if the BSOD is solved. I was a fan of avast but ditched it for AVG instead few months back due to BSOD in version 5 series.
I am 26 hours stable on 5.0.594 so far. I have done everything I used to do that caused a BSOD crash before, only no crash this time. I will report in again after 48 hours has passed.
Thankfully I have had no problems on my Windows 7 system but when I did have on my XP Pro system they were fixed quite quickly after I provided the dumps to support. 8)
I looked again on your dump and I saw that our driver tried to read definitely valid memory block from 0xfffff88006a41330 address, instead CPU read it from fffff88006a49330 address.
If you convert these addresses into binary form, you’ll get:
Right now my memory, 2x2GB DDR3 1600 OCZ Black Edition, is running at 1.65 volts with 8-8-8-24 timings. I can lower the voltage as you suggest, but 1.65 volts is what OCZ recommends to use them at.
Could it possibly be my memory is not getting enough power due to bad power supply? I do question my power supply with my new build since it’s about 3.5 years old and only 500 watts.
Quite possible you don’t get enough “juice” from the psu. That psu is really weak for a newer system, what are your other system specs ? Especially interested in the gpu and cpu.
