BSOD - Driver IRQL not less or equal & PCI serial port driver

L

LamWarp

This started happening after I updated windows to 2004.

Occasionally I would get a BSOD, and it would happen at different times, so I don't know what I exactly did to cause it.


The "stop code" was: "DRIVER IRQL NOT LESS OR EQUAL". I've gotten this problem a week ago, but I thought it was a one-off thing, but it kept happening.

And the thing that failed was: "BTHport.sys" (Which I read was a windows Bluetooth driver I think)


I assumed that it was the update that started it, so I reverted back to 1909, and it was fine for a while, but then it happened again, I don't know what causes it to happen, and it always happens at an unexpected time. Any fix for it?


I also noticed that in "device manager', under "Other Devices", there's a yellow triangle under 'PCI Serial Port' that says 'couldn't install driver'. Maybe that's what causes it since my Wifi/Bluetooth card is in a PCI slot. Clicking update driver didn't work, it said it failed. Is there any way to fix that as well?
