Constant BSOD - help appreciated!

maloflora · 26 Jun 2015 at 18:45

Hi all,

I recently built a new PC with the following specs:

Gigabyte Z97X-Gaming 7 - Devils Canyon Core i7 4790K CPU & Motherboard Bundle
MSI GeForce GTX 970 Gaming Edition
TeamGroup Vulcan RED 8GB (2x4GB) DDR3 PC3-19200C11 2400MHz
Corsair Hydro H100i
Phantex Enthoo Primo

After a few weeks of working fine, suddenly from nowhere I get BSODs every time I log into Windows. I'm not overclocking at all, and temps seem fine for the CPU - hovering around 30 at idle and 50 max.

I can get into windows in safe mode, but not normally. The .dmp file shows two files in red (think that means in the crash stack):
hal.dll
ntoskrnl.exe

Bug check code: 0x00000124

I've run overnight MemTest - 12 runs no errors

In windows safe mode I've run 15 mins of Prime95.

All help desperately appreciated for what to try next!

No it does it every time, though there is no problem at all with safe mode. I've got VCORE at 1.308 - the BIOS optimised defaults. What other voltages should I be looking at?

Thanks for all the replies. Window 7 64 bit.
Monitor, Logitech G7 speakers, G11 keyboard, G500 mouse
1 SSD (boot), 1 HD
Antec TruePower New Modular 650W Power Supply - about 4 years old

Will try memory at lower speeds

Sorry - I was already running it at 1.2 with no overclock - in desperation I reset BIOS and it put VCORE back to 1.3

It does it on both voltages.

Thanks all. I'd already updated BIOS to F7 - that still set VCORE at 1.308. I've tried it at 1.2 and 1.25 - same happens. Have tried XMP and 1600 memory.

Tried Windows file checker and got 'Windows Resource Protection did not find any integrity violations.'

Should I try a clean reinstall and see if it can make it through the process? Or is it a faulty MB maybe? or CPU?

Edit: The SSD is a Toshiba Thnsnh128gbst. Something like http://toshiba.semicon-storage.com/e...-ssd/hg5d.html

BIOS flashed to F8a - optimised settings produce same error I'm afraid!

Should I remove GPU and use integrated graphics? Try and reinstall windows?

Success! I used System restore to take me back to before I installed Gigabyte App Centre - I think that was causing the problems. I also put memory into slots 2 and 4 - not sure if that made any difference.

Thanks for all the help - fingers crossed it stays ok!
