    SFX is probably the form factor. If it is an OEM computer, could you get us the Manufacturer and model of it please?

    Is the computer actually booting, but you just have no graphics?

    We can try to help you, but it would be best if you had access to the computer while we did.
    *I'm about to mark this thread as solved*

    I know the computer is not booting. There's no indication it is- we couldn't get a POST screen, fans revving, no difference even after waiting for several minutes. You know how when you start a computer at the POST screen you can turn numlock and capslock on/ off? Can't even do that (If you ask me- no indications of it even POSTing). And no difference without RAM. I've tried everything I can think of except for trying a different PSU, I'm getting to the bottom of my list of things that might be wrong and at the very bottom is the board (and CPU). If its a RAM problem then both sticks are bad

    I know we could continue on with searching for the problem and I appreciate everyone's feedback but I don't think its necessary anymore. I'll try the other PSU and some last other things, but if that doesn't work, really what else could be wrong? I've isolated out everything else. It's his computer- I'll tell him what everyone here said and the last things I think are wrong and see what he wants to do.

    You could try to create an installation USB drive using the Media Creation tool (Option 1 USB Flash Drive - Create to Install Windows 10 - Windows 10 Forums) and see if it will boot from that. You can do some troubleshooting from it, or reinstall windows with it. Assuming you can get that far.

    Unplug the computer, hold the power button down for 30 seconds, until all LED lights go out, then remove the CMOS battery for about 30 seconds. Put the battery back in, plug the computer back in and try to start it. It should send you straight to the BIOS. Once in bios, see what mode the sata controller is, see if it detects the ram, hard drive and graphics card. Set Optimized defaults (F5 on most computers) Make sure the sata mode is the same as it was, set the boot order the same as it was before setting defaults, save and exit. Don't change anything else. See if that helps.

    Honestly, the CPU is the last thing to suspect. They hardly ever go out this quick unless they have been seriously abused. When the fans turn on, do the GPU fans come on too? Does the board have any warning LEDs? I understand your position, but we will be glad to help if we can.

    First thing should have been to test the PSU, borrow another PSU and swap it out. 450watts on an older and brandless PSU, my opinion is that the PSU is the problem.

    Unbranded PSU's tend to be over rated, unstable but mostly pure junk.

    Another thing I suspect is that the PSU my have fried the MB and the Card, you might be able to RMA your card and motherboard with the manufacturers but I doubt since the PSU is what may have cooked them.

    I'll bet it's a corrupt Bios.
