Problem description: I am using some older hardware to make a small desktop workstation. Sandy Bridge i5 2500, H67 mobo (link below), no video card, onboard graphics only. This is a clean install, done just an hour ago. I reformatted a small SSD I had and installed win 10 home 64 off a USB drive. The computer was connected to the monitor via hdmi, Everything installed fine. Worked fine. After the install windows booted normally, then the screen went blank, and showed no signal. I believe it was right after windows installed the intel graphics driver. After some messing around, I find the following:

Graphics output works fine for bios, windows load, safe mode. When windows actually loads, I lose signal in both HDMI and DVI. However D-sub still works. When using D sub, everything is completely normal. It is full resolution, I can watch video etc. The display adapter shows it is functioning fine.

Attempted fixes: I have updated windows. I have tested multiple[le screens and cables and confirmed 100% that they are not at fault. I have updated to the most recent intel display driver. I removed that, and installed the one appropriate to the generation of hardware. No changes in behavior. I have looked through the bios and looked at graphics settings, they all seem correct. I looked for a Biostar specific driver for this mobo, but they do not seem to have one available, only audio lan etc, which are not issues.

I also know, that literally a day ago, this motherboard was working fine, with onboard only graphics, with a sandy bridge i3. I swapped the i3 for an i5, and added some RAM and did the clean install.

Recent changes: See above

Make sure you're on the latest motherboard BIOS if you haven't already.
