This is irrating. I haven't changed anything on my main PC for ages. Now suddenly since yesterday I am getting BSOD multiple times per day - usually saying DPC failed occasionally on boot splash screen saying Kernal switch mode exception.
As far as I am aware all my drivers are totally up to date. Windows integrity scan elevated sfc /scannow returns no errors. But if I go away and leave my PC for 20 - 30 minutes a crash DPC is almost certain to happen. I haven't chnaged my power settings in ages. My main UPS just had new batteries installed and seems rock solid. Windows last did a major update about 1-2 weeks ago.
Any suggestion greatly appreciated!
