Ok, I can't prove you wrong and I can't prove my own case.
I am just pointing out that if (when may be more suitable) problem starts, there are more options he can try out.

Always? Even through they have not been updated for three years and there have been 4 releases of Windows 10 in that time? My experience is that if a newer driver is available from, say, Intels or...

Well, nobody makes BIOS updates if they did not think they were needed, sort of self explanatory. It is a nobrainer for me personally but there are those who are feeling differently based on their...

For some reason I can't open your attachment... Will check when I am back by the pc.

So, yeah, this is odd. I have no idea why this is happening but what does the log tell you? Check the log and specifically the stuff it writes around the times this happens. Could be ITunes, could...

But you have the benefit of downloading and installing updated versions, including drivers, and that is usually a great thing. No software is without it's drawbacks but old is seldom gold in any...

Download Windows Media Creation Tool on a working pc and have an USB-dongle ready, 8GB will suffice, choose to create usb, when finished you boot it up in the troublesome pc and choose either repair...

Depends on the hardware you bought, I have the Asus Z97-A mobo and Asus Strix GTX 980 GPU and both have new BIOS/firmware on the product/support page from Asus. The second part is tricky, do you know...

And, if it is in fact due to a driver with the new GPU, bsods should vanish while testing the rig with the old GPU, if that is the case reinstalling Windows could help a great deal when the new GPU...

Besides needed BIOS and firmware updates for the mobo and GPU, there could be a problem with either that new PSU or the new GPU, try the old GPU for a while and if you don't get any more bsods it may...
