Recurrent BSOD crashes

Hi tenforums!

I've suddently been getting some crashes, although no hardware modifications were made or new softwares/drivers installed. They happen during games, or video playback.

Apparently the most recent crashes are caused by ntoskrnl.sys and wdf01000.sys for an DRIVER_IRQL_NOT_LESS_OR_EQUAL error.

Here is the zip file generated by the log collector.

Thank you very much for your help!

The Prolific Serial port driver (c:\windows\system32\drivers\ser2pl64.sys) is causing the BSODs.

Code:

BugCheck D1, {38, 2, 1, fffff8014c7453ec}

*** WARNING: Unable to verify timestamp for ser2pl64.sys
*** ERROR: Module load completed but symbols could not be loaded for ser2pl64.sys
Probably caused by : ser2pl64.sys ( ser2pl64+78f1 )

And it is extremely old.

Code:

What is the Prolific chip type that you are using? Asking, because ....

NOTE:
- Windows 8/8.1/Server2012/Server2012R2 and Windows 10 are NOT supported in PL2303HXA/XA EOL chip versions (discontinued).
- Download latest PL2303 CheckChipVersion tool program to check chip version in Windows 7. (Or ask your cable vendor)
- Prolific recommends cables with PL2303HXD or PL2303TA chip.
- Windows 98/ME/2000/XP driver technical support are discontinued.

If yours is any of these two, you should have to disconnect the Prolific cable.

For any other chipset type: Products
.... update the driver.

Welcome. :)

I hope you will not see this particular BSOD anymore.
