NetSvcHelp.exe - Application Error

[NnelK]

About 2 days from now i started getting an error message from NetSvcHelp.exe: The instruction at 0x6ff9910e referenced memory at 0x00000000. The memory could not be read.

I think the problem started when i removed my 4GB stick. The stick was actually meant to go to another computer but i didnt had MOBO for it yet. So, why not should i use it.

I normally had 8GB Crucial ballistix sport 1600MHz (2x4GB) in the right sockets. I installed the other 4GB Crucial ballistix sport 1333MHz, so i had a total of 12GB RAM. BIOS overclocking is set to AUTO, so it was downgrading automaticly.

But now when i removed it, im getting this error message and when i start my computer, desktop files are loading so slowly, i cant even go to Windows search (Windows 8.1 64bit), even not Task Manager. It just crashes for 20-30 seconds. The only thing what i can do is i have programs pinned on taskbar, like google chrome and etc. Those are working normally when opening. So i can browse internet normally.

Windows and google chrome and etc. have stored on a 256GB Samsung 840 EVO SSD. SSD should be healthy.

What is the problem, how to fix it?

Computer specs:
Asus Z87-A
Intel i5-4670K
Samsung 840 EVO
Wester Digital BLUE 1TB
GTX 660 TI SLI
Corsair 600W

Clear CMOS.

Maybe load default settings in BIOS also.

Thank you, i did it but now the error code has been changed a little: The instruction at 0x6fa2910e referenced memory at 0x00000000. The memory could not be read.

It still loads desktop files and etc. really slowly.

It's really weird. I did cleaning with Malwarebytes too but that didnt work out too. Can it be software problem?

Try running under elevated command prompt - sfc /scannow. This will scan for and replace any corrupt system files.

Test ONE DIMM at a time and in different memory slots. This will help determine whether a certain DIMM and/or slot is faulty.

It changes the error message everytime i reboot. I've seen that sometimes it doesn't give me any error messages at all when i reboot. There is over 75% change that it gives me the error message.

I did that sfc /scannow, fixed some corrupted files but didn't fix my problem. Memory DIMM's should be okay.

Testing the DIMM's one at a time and in each slot is strongly recommended, as it is suspected there may be a faulty DIMM or a faulty DIMM slot.

EDIT: Could try this in elevated command prompt - chkdsk C: /f. Where C: is the boot/operating system drive. If boot drive is another letter ( for example D: ), then substitute that letter instead of C:.

Could also try full Windows repair by booting up using original Windows installation disk and selecting repair option.

The next suggested procedure (after the above test) would be a complete and thorough wipe and re-format of the HDD, followed by re-installing operating system, then the latest chipset and other motherboard drivers, then the latest video and sound card drivers etc.

This computer is too new for DIMM problems. I needed to install a new windows anyway beacuse it was failing to install Win Updates (with older updates they don't give you a free Windows 10) and after that the problem seems to be fixed. Thank you for your help!
