I'm experiencing multiple bluescreens for a couple of months now. Their error code is as diverse as their time of occurence... Sometimes it happens during gaming, sometimes when watching videos, sometimes when the computer is idle.

These are the bluescreens I see most often:

• PAGE_FAULT_IN_NONPAGED_AREA
• KMODE_EXCEPTION_NOT_HANDLED
• IRQL_NOT_LESS_OR_EQUAL
• SYSTEM_SERVICE_EXCEPTION
• SYSTEM_THREAD_EXCEPTION
• INTERRUPT_EXCEPTION_NOT_HANDLED
• DRIVER_IRQL_NOT_LESS_OR_EQUAL
• DRIVER_OVERRAN_STACK_BUFFER

Responsible drivers (according to the memory dumps):

• hal.dll
• tcpip.sys
• dxgmms1.sys
• ndis.sys
• mouhid.sys
• atikmdag.sys
• dump_atapi.sys
• and of course: ntoskrnl.exe

My first thought was a driver incompatibility because I am using Windows 8 and some of the bluescreens seem to come from driver issues. All drivers are up to date.
I'm afraid that my memory is broken or the mainboard or both. I used the windows integrated memtest which didn't find any errors. Memtest86 found some errors. Does it make sense to buy new memory? Couldn't it be a problem of the board as well?

I also read that my memory could run at a too low voltage. But it's set to 1.5V as recommended. Another guess would be to set the memory's latencies manually, but how do I know which ones to try?

Here is a screenshot of bluescreenview showing the latest bluescreens. Maybe someone has faced the same behavior before and found a solution. Any ideas or suggestions?

Current setup on which the bluescreens occur.

• Windows 8 RTM (6.2.9200)
• Asrock 970 Extreme4
• AMD FX-8150
• ATI Radeon HD5850
• 16 GB RAM (DDR3-1800)
• Latest drivers for all devices
