I updated my DH67CL motherboard for the first time (it's around 3 years old) because I read it may fix random bluescreens I'd been getting. However, when doing the F7 USB flash method, I used the file you're supposed to use when doing BIOS recovery, BL0160.BIO. However it seemed to work anyway and said flashing was successful. When I restarted, however, the computer turns on, but it doesn't POST and no USB items like mouse, keyboard, and flash drive show any indication that they're connecting.
I've tried removing the yellow tab to reset CMOS, and removing the mobo battery, and putting the recovery file on a flash drive and booting with it plugged in. Am I going to need a new motherboard?
So what exactly happens? Does the pc start up at all? starts then shuts down? can you get into the bios? does it display?
It "turns on" in that the case and CPU fans spin, and the DVD tray can open and close, but that's it. No beeps, no BIOS, no display period. It doesn't turn itself off, it'll just stay on like that indefinitely.
Do you have a Gpu installed? Try connecting to the onboard if you can and see if you get it to display.
I used to but at one point my computer crashed and no longer displayed through the GPU HDMI port. I had to remove the GPU completely and connect to the motherboard's HDMI port. These issues might be related.
