RANDON STOPCODE - ntoskrnl.exe+16bfd0.

I done a GPU Stress test no problems however prime95 shows up this error

"Prime 95 ERROR:rounding was 0.5 less than 0.4 and hardware failure "

Any ideas

Many Thanks

Hi,
theres only one bsod dump which shows memory_corruption at one point:

Code:

0x0000001E:    KMODE_EXCEPTION_NOT_HANDLED (1.08.2017 13:04:02) [Windows 10]

After reading your memtest results, the tests also failed:

To verify I recommend running Memtest V5.01 too:

Diagnostic Test

 RAM TEST

Run MemTest86+ V5.01 to analyse your RAM. MemTest86+ - Test RAM - Windows 10 Forums

   Note

MemTest86+ V5.01 needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Make a photo of the result and post it.

Test has been running 5 mins found 3 errors .. Does this mean ram is at fault will post details after complete.

Yes the RAM is gone...

There were operating system corruption problems reported in the event log.
When you have properly functioning ram see if you can fix the operating system problem by:
1) opening administrative command prompt and type or copy and paste:
2) sfc /scannow
3) dism /online /cleanup-image /checkhealth
4) dism /online /cleanup-image /scanhealth
5) dism /online /cleanup-image /restorehealth
6) in case the above steps are unable to complete plan an in place upgrade repair using a windows 10 iso:
Download Windows 10
7) Repair Install Windows 10 with an In-place Upgrade Windows 10 Installation Upgrade Tutorials

file system and os corruption could caused by defective memory so the first step should be replacing the RAM

Ended up running the memetest over night had 381 errors so RAM is dud.. I got a replacement delivered this morning did a test found no errors then did a clean install of windows 10 pro, touch wood all seems ok. Now to RMA this RAM. Great help from BSODHUNTER and zbook for the advice given. I will post back in couple of days with an update.
