📎 AI Summary:
The thread discusses a Windows 7 system experiencing multiple Blue Screen of Death (BSOD) errors with bug check code 0x0000003b, following hardware upgrades including the motherboard, PSU, and CPU. The original poster provides detailed system information and troubleshooting steps already taken, such as driver updates, reseating components, and running Memtest with no errors. A responder suggests the BSOD may be caused by corrupt drivers or hardware faults—possibly RAM or graphics issues—and recommends steps like removing third-party applications, verifying system temps, running system file checks, and testing the GPU RAM. Overall, the advice aims to identify whether software corruption or hardware failure underlies the crashes.

I have multiple bsod's with "0x0000003b " bug check code.
This is the most recent one.
0x0000003b
00000000`c0000005
fffff800`03088e5e
fffff880`0a7a5ea0
00000000`00000000
Cause by driver/address: ntoskrnl.exe+75169

Recently installed new Mobo, PSU and CPU. I have tried reinstalling Vid driver, updating bios, installing all missing drivers, reseating gpu and rams, chkdsk, and Memtest(no error) .
Mobo/Cpu Z87-G45 Gaming/ i5 4670k
Psu Cx600 Cx 600 Watt Atx/Eps

Hi,
the causes for the Bugcheck range from corrupt drivers or third party apps to possible hardware faults (usually RAM). I also noticed you had dump files with probable causes for graphics, Network and memory corruption.
Looking through your driver stack I see your drivers are of the latest versions and all looks good.

Try removing any third party apps just as a simple test to see if the bsod stops. For example I found this driver cropping up a lot:
ALSysIO64.sy : Core Temp - CPU temperature monitor or at least I think it is. Notice the 's' missing on the .sys. I wonder if this is down to corruption. Try removing and re-installing:
http://www.alcpu.com/CoreTemp/

What are your system temps like?

Check for system corruption by running a system file check. Open an admin command prompt (right click on command prompt and click run as admin) and type:
sfc /scannow
Press enter and await results.

Please check the RAM on your GPU by running the test found here:
Link Removed

Can you post how long you tested the RAM for?
