There are no new dump files.
Check in these directories:

C:/Windows/minidump

C:/Windows/memory.dmp

If you have Small Memory Dumps then copy them to the desktop, zip them up and upload them in your next reply.

If you have a Kernel Memory Dump then copy it to the desktop, then upload it to a file sharing site like OneDrive then post the link here.

Nope still nothing, we could give Driver Verifier a try.

Enable driver verifier but only enable the options: Standard settings and IRP logging step 3.
Don't enable Force Pending I/O Requests

Enable Driver Verifier to monitor the drivers.
Driver Verifier -Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

information   Information

We use Driver Verifier as it puts a stress on the drivers, and so it makes the unstable drivers crash. This should flag the driver responsible in the dump file.
It

Driver Verifier will make the system laggy, this is normal so don't worry.

Before enabling DV, make sure that you have earlier System restore points made in your computer.

If there are no points, make a System Restore Point Manually

I've had the Driver Verifier running since 8 am this morning, but it hasn't crashed yet. Can I turn my computer off overnight, or should I let it run? Overnight I won't be working (which is when the crashes always happen). Thanks.

It's up to you.
You can leaving it running or turn it off and use the PC whenever you want.

OK the driver verifier ran for about 27 hours (but I turned it off when I was sleeping), and a crash didn't happen. It did slow my system down quite immensely however! Does this mean the driver verifier didn't help? Is there a next step I should take? Thanks!

If Driver Verifier find nothing then hardware testing should be the next step.

Stress test your CPU with Prime95

I recommend running Prime95 for around 2 hours

warning   Warning

As with most stress tests your component's temperature will rapidly increase.
It is advised that you download a temperature monitoring program like HWmonitor
Keep an eye on your temperatures and stop the tests if it starts to overheat


Stress test your graphics card with Furmark

I recommend running it for around 30 minutes

warning   Warning

Furmark will increase the temperature of your GPU rapidly so keep and eye on your temperatures


Memtest86 will test your RAM

information   Information

Run Memtest86 for at least 8 passes so we get enough information to confirm that your RAM isn't failing


Run a Disk Check to scan for errors

Note   Note

Afterwards go into an Elevated Command Prompt (Run as administrator) and type in sfc /scannow
If it finds errors reboot and run the scan two more times


Run SeaTools to see if your HDD or SSD is failing

^^tried the above. with SeaTools, both drives passed short DST, short generic, and long generic. Disk Check revealed no problems. Furmark would not run properly - like 2 or 1 FPS even with low resolution. Prime95 passed 2 hours. Memtest had 5 passes without errors.

I've been having problems with my c1000a wireless router crashing, which is somehow being caused by my T400 laptop (all devices would connect and function on router until I turned on T400 wifi, which would cause the router to crash). I reverted the Intel 5300 AGN driver from the Intel 14.3.2.1 back to the Microsoft 12.4.1.4. The T400 is no longer crashing the router, however I just had another BSOD. I assume this is again caused by the 5300 driver. On rebooting, Windows popped up with a little message saying I could find detail of the error in two files (both attached here).

Can anyone suggest what the heck might be going wrong? I'm wondering if I should replace this stupid Intel 5300 card.

Any suggestions? Just had another crash running Intel 5300 AGN driver version 14.3.0.6.

Driver versions 12.4.1.4 and 14.3.0.6 both cause my machine to crash, whereas driver version 14.3.2.1 causes the wifi router and modem to crash. I'm not sure what to do at this point beyond replacing the 5300 card.

Just had a third crash in as many days. Can anyone recommend a way forward? Or, is there no solution and I should stop posting here? Thanks!
