About a week ago I had my homebuilt computer suddenly die while it was up and running. I have pretty much determined that the motherboard failed and I have purchased a replacement. I installed it today and everything went fine but when I turned on the power everything appeared to start up and run normally but I'm not getting anything up on the display. So.....what gives?? I do not use a separate graphics card and the graphics display is handled by the CPU which is an Intel Core i5-6500 Skylake Quad-Core 3.2 GHz LGA 1151 65W Intel HD Graphics 530. I'm wondering if something in the CPU that handles the graphics has failed. Or maybe the whole CPU has failed. I can't tell what's going on because I can't see anything up on the display. Does anybody have any suggestions?? I'd like to try to troubleshoot this problem before I go and spend a bunch of $$$ purchasing a new CPU.
