Question Desperatly looking for help: random BSOD/freezes

[michaellepke]

hi. the issues have been bugging me for quite a while now. so im very grateful for your help.

Specs:

Board: Asus Z68 V Pro
CPU: i5-2500k
RAM: Samsung 8GB DDR3 1333
GPU: GTX 1070 TI
PSU: Seasonic 80 Plus
SSHD: Seagate Firecuda
Chassis: none
Cooler: Be Quiet Dark Rock 3

windows 10 Pro 64bit ;
latest bios v3603.

Issues:

• BSOD (from more frequent to less): clock watchdog timeout; whea uncorrectable error; machine check exception
• hard freezes (no BSOD, no error codes etc; -> forced to shutdown with power button)
• mouse didnt get detected (had to replug it), i think that happened twice

Story:

• system running fine
• tried different overlock for i5-2500k
• found a working setup ( 4.8 Ghz @ 1.5 V), temps etc were fine
• did some other registry tweaks (network throttling, system responsiveness etc)
• everything worked fine
• after some time BSOD and/or freezes occured

Allready tried:

• reverting all changes: tweaks, overlock
• fiddled with graphic drivers and settings
• windows was stuck on an older version
• made a repair install -> windows succesfully updated
• DISM -> sfc /scannow
• chkdsk /f /r
• fresh windows 10 installation from USB
• after completing the installation -> BSOD
• updated windows
• installed drivers from asus -> only USB 3 driver is offered for windows 10
• changed CMOS battery
• installed latest graphics driver
• installed latest version of logitech gaming software
• noticed strange "distortion" of graphical elements (gfx install UI and logitech software)
• usually the system freezes and stay like that or a BSOD appears: the last time, i noticed some slow down in responsiveness before BSOD : machine check exception

Thank you guys !

Always list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS: Which version of the OS are you on?

^ being as specific as possible.

Are you on the latest BIOS for that Z68 chipset board? How old is your PSU? Are you on the stock cooler?

ive also just noticed that the windows integrity report as part of windows security says "some apps stopped working".
Problem solving says , the save location for temporary internet files would have been changed. -> could reset it to default

hi





- ive used

Intel® Processor Diagnostic Tool
short default test: all passed


burn in (3hours): passed


temperature : passed





- Hot CPU Tester Pro (3 hours): no issues (see attachment)


- Windows RAM test: passed





- ive always used asus highest performance preset in BIOS which would automatically overclock to 4.3 Ghz


just for testing purposes, ive set it to energy saving mode -> had no crashes/freezes for a while -> pretty sure its stable there (turbo would overclock to 3.7 Ghz)





- set it back to high performance :-> long time no issues then freeze during low resource game hearthstone


- PSU makes rattling noises (going by the sound, probably fan's ball bearing)


- when i changed the CMOS battery, the BIOS didnt get fully reset ( Overlock profiles were/are still there)





Questions:





- could it be that the PSU (at least 4.5 years old) cant handle the high performance settings anymore? -> need a replacement ?


- is the CMOS corrupt? (cant set preset settings properly anymore ?) do i have to use that mainboard switch?
