BSOD - has startet after years with no problems

For Crystal Disk Info follow these steps:

Click the Caution > Move the Sliders to the left (until the values on the right equal zero) > Apply

What were the results of the hard-drive tests?

hi
sliders moved to 0
and added the minidump´s of today

bsodwhat

the tests where all good or there where no problems recorded. therefore i didn´t ad any comment on them

Code:

BugCheck 3B, {c0000005, fffff80003812a9b, fffff88008573d50, 0}

Probably caused by : Pool_Corruption ( nt!ExDeferredFreePool+1df )

Code:

Usual causes:  System service, Device driver, graphics driver, memory

-->Memory:

• RAM - Test with Memtest86+

Run Memtest86+ for least 7-8 passes, and preferably overnight as it can take a while to fully complete.

Test each RAM stick individually, if an error is found then move the same RAM stick into the next DIMM slot and test again, if errors are found for the same RAM stick in every available slot then you have a faulty RAM module. On the other hand, if no errors are found in the next slot or the other slots for the same RAM module, then you have a faulty DIMM slot.

Test each RAM stick and every motherboard DIMM slot available.

-->Could you also upload the SFC /SCANNOW and CHKDSK logs if you haven't done so:

• Check Disk (chkdsk) - Read Event Viewer Log
• SFC /SCANNOW Command - System File Checker
