Sorry to be lazy and post here, but I'm so far out of the loop on low to mid-level new hardware it's not even funny. I've got a HTPC that's running a chip I don't recall sitting in an EVGA 750i SLi FTW mobo, vid card is a GTX 670, and I have an old PCI Xonar D2 sound card sitting in there, all housed in a nice Silverstone HTPC case. OS is windows 10 run off a SSD. Something has been crashing regularly and causing video and audio to cut out. Recently (last night) display artifacts have begun to appear. Reinstalling and updating drivers hasn't worked, and the most recent drivers for the mobo are from 2015 and for Windows 7. I don't know if it's the video card, motherboard, or one of the other components. If I needed to replace the chip, mobo, ram, and video card, is there a current setup that is recommended? The case will take an ATX motherboard. I'd like it to be somewhat future-proof in that it should be able to handle 4k video. It's mostly used for watching netflix and playing hd content off my home network. Do I even need a sound card these days? They don't even make motherboards with a slot for the Xonar D2 any more and the thing had crappy drivers anyway. Less cost is mo' better. Are there motherboards that also pump audio out through the HDMI port? I run everything to my home theater receiver and visuals out to my TV. Any input or advice you guys have would be much appreciated!
