!!!Fun!!!:
My computer decided to crap out during the middle of a bit of post-work Battlefield 4, giving the dreaded black screen of death, something I haven't experienced since prior to reformatting around 6 months ago. It was working fine, until the FPS dipped to about 1, then I lost everything and couldn't even Ctrl+Alt+Del my way out.
Restarting brings me to the default Windows "Welcome" screen, which displays a bit of text for a split second then freezes, with the cursor still controllable. It does not progress past this blue screen, simply displaying the Windows 7 Professional logo at the bottom.
I am able to boot into safe mode, and even with Networking, so that's a small measure of comfort.
Heat does not appear to be an issue. The computer is dusted and cleaned on a semi-monthly basis, mainly due to the presence of a cat that frequents the room.The CPU is a water cooled i7, and ASUS' BIOS utility didn't reveal any heat issues upon restart. The only major change to the system was upgrading from a pair of nVidia GTX 560s to a single 970. The PSU is a sturdy 850 watt unit, and I am well under that number for power usage for my computer. Power surge should similarly be out of the question, as I have it hooked up to a decent UPS, and no other devices in my house were affected.
I've unplugged all non-essential peripherals to no effect.
I believe the error to be with nVidia's graphics drivers, so I'm attempting a clean install of a previous version. System Restore got stuck at the Initializing stage for 10 minutes, and as such appears to be useless.
Any additional advice or ideas towards fixing this issue would be appreciated.
Edit: I'm able to boot normally now, though it takes about a minute, which is about a minute longer than it used to take as my system drive is an SSD. I'm running some diagnostics to see what might have caused it in the meantime.
