Hi everyone
I'm writing this post to share the result of my 4 day fighting with my new PC and Windows 7.
I've just bought my new PC with the following configuration:
Motherboard: P5Q Deluxe
CPU: Intel Core 2 Quad Q9400
Graphic: GeForce 260GTX
HDD: Patriot Warp 2.5" SATA2 128GB SSD
PSU: Cooler Master 900W
OS: Windows 7 ver. 6.1.7600 Build 7600
Then I decided to install Windows 7 64-bit and then all my problems started.
Here are the problems I had:
Randomly my PC hanged and I saw just white screen without any letters or BSOD with nvlddmkm.sys error (for 1 seconds, then automatic reboot).
So I did not know wether WSOD and BSOD are caused by the same problem.
nvlddmkm.sys fix
I had to use my camera to make a snapshot of BSOD to actually see the error and all details during BSOD. The problem was that I could not reproduced BSOD in any way.
Fortunately, I was able to record it on video and see that problem is related to nvlddmkm.sys file.
I've searched for forums and here is the solution that worked for me:
- I uninstalled video drivers installed by Windows Update by doing the following:
- Start in safe mode (press F8 on boot)
- Start->cmd
- sc delete nvsvc
- sc delete nvlddmkm
By doing this you deleting the service with drivers.
- I installed the latest version of nVidia drivers from official website Drivers - Download NVIDIA Drivers
After that I didn't have a single BSOD.
But I have another major problem.
Randomly my computer started to hag for 3-5 seconds and then I saw just white or grey screen. If I had music playing on the background, it continues to play normally without looping. The keyboard stopped responding. I had to reset PC.
After restart system EventViever (eventvwr.msc) didn't show anything strange, except unexpected boot.
I was totally lost as I didn't know the cause of the problem.
Needless to say, that Battlefield 2 and Far Cry 2 running without a single problem on highest settings which made me even more confused.
WSOD fix
After reading and trying a lot of things, here is what was the solution:
The BIOS had an "Auto" setting for RAM voltage, and as I have 4 sticks of RAM, the manufacturer states that it is good to specify the voltage directly.
I specified 2.2 Volts - the maximum voltage for these RAM. Also, the manufacturer recommended to put the timings, but I didn't do that trying to get as much stable system as possible.
After fixing the above I had to try a stress test. The best one that I could get is OCCT located at OCCT Website english
I hope I will be able to help someone with problems like mine.
