If you encounter the DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATION Blue Screen error with an error code of 0x000000CE then it means that a driver failed to cancel the pending operations before unloading. Some of the driver files that might be the culprit include the intelppm.sys, intcdaud.sys, tmxpflt.sys, mrxsmb.sys and asusptpfilter.sys.
This kind of Blue Screen error occurs when the driver failed to cancel lookaside lists, worker threads, DPCs, and other items before unloading. You can usually identify which driver file is triggering the BSOD error in the BSOD error itself since its name would be printed on the blue screen and stored in memory at the location (PUNICODE_STRING) KiBugCheckDriver.

Option 1 – Perform a System Restore
Performing System Restore might help you in fixing the SYNTP.SYS Blue Screen error. You can do this option either by booting into Safe Mode or in System Restore.

All you have to do is enter the BIOS first and then use the Arrow and Enter keys to select your choices. And if you can’t seem to find it, look for specific instructions from your OEM or you could also look out for instructions from the manufacturer of your motherboard.
Option 3 – Update or rollback your device drivers
If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.
- Open the Devices Manager from the Win X Menu.
- Then locate the device drivers and right-click on them to open the Properties.

You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.
Option 4 – Try to run the CHKDSK utility
Running the CHKDSK utility might also help you resolve the DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS Blue Screen error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in.
