I own a DP55KG motherboard and am having strange issues as of late and am wondering what could be wrong (I've got the idea my motherboard or processor is slowly failing ).
Every few days my pc experiences a blank screen for a few seconds. After the screen turns back on I'm receiving the error message that the nvlddmkm service stopped responding and was recovered successfully. Right before that happens an error occurs the Event Viewer. It's the following error:
Event ID: 17
A corrected hardware error has occurred.
Component: PCI Express Root Port
Error Source: Advanced Error Reporting (PCI Express)
Vendor ID:Device ID: 0x8086:0xd138
Class Code: 0x30400
The details view of this entry contains further information.
However since 2 weeks I've been having sudden hangs with no errors at all. Can't even press the Numlock key on my keyboard and reset button doesn't reset the pc as it normally would. Instead it shuts down for a few seconds and then the pc comes back on again. Yesterday during the late afternoon my computer suddenly switched to a BSOD with a bug check code of: 0x0000101 which means a Watchdog Event Timeout occured.
PSU: Enermax Modu82+ 625W
Motherboard: Intel DP55KG
CPU: Intel Core i7 860 (not OCed)
Memory: Kingston HyperX 4x 2GB (CL-7-7-7 LLCM, but I've set the timings according to the SPD)
Graphics Card: MSI Geforce GTX460 (1GB RAM,)
HDD: (Intel AHCI SATA Port 1): Corsair 60GB SDD (with the latest 2.0 FW)
ODD: (Intel AHCI SATA Port 2): Sony DVD-/+RW
RAID Controller: 3Ware 9650SE-4LPML SATAII RAID Controller
HDD: 2x Western Digital VelociRaptor 300GB
OS: Microsoft Windows 7 Professional 64-Bit (installed in BIOS mode; (u)EFI gave too many problems) and Gentoo Linux 64-Bit with a custom compiled 2.6.39 kernel.
Things I've tried:
- Updating all drivers and firmware
- If my pc boots and doesn't have a crash, then it's extremely stable. I am able to game for hours, watch movies and do stuff without having a crash;
- I've tried running a CPU / Mem stress test for 4 hours using Prime95 and it did not crash and remained stable (including voltages and temps);
- Memtest for a whole night shows no errors;
Is there anybody who might have another clue? Could this be another BIOS bug causing these problems, since the BIOS had similar problems before?
