I've put in a new video card. Made sure it was low enough wattage for the power supply, but it still won't boot right. It is a PCIe card, an Nvidia GT 1030. I think I just don't know how to install it correctly.
If I just put the card in, and try to start the computer normally after that, there's a little drive noise, but the fans don't turn very fast, there's no beep, and nothing on screen.
If I use the CMOS reset jumper, it will start after that, but with issues. The CPU fan runs on high constantly, and doesn't idle. The BIOS settings can't be changed, or it returns to the no boot condition. Computer cannot restart, or it similarly won't boot. Either the jumper to reset the BIOS, or running it with no CMOS battery and unplugging it each time, is required to get it to boot.
When it does start up after reset, it acts odd, even then. It comes on for a second, the power led goes off for about two, then things light up again, and it brings up the screen where it says the CPU was changed, and suggests hitting F1 to continue, or F2 to enter setup. Can't pick anything other than F1 to continue. If BIOS setup is entered with F2, even if exited without saving any changes, the system winds up back in the no boot situation.
It can load up Linux Mint after skipping setup, and most things basically work. The main exception is audio. The audio feature of the video card may be blocking onboard audio. The monitor is connected to the video card with a DVI-D to VGA adapter with no audio output, so that's not great.
Are there specific BIOS settings required, before installing the card or after resetting CMOS, to avoid the no boot condition? If not that, then what?
