So when I first put it together I was having some trouble getting the windows installation CD to boot, after i changed the priorities in bios it was okay, then when I started it was getting stuck at 'Expanding Files', I read online that if things like Floppy Disks,and USB controller were enabled it could be slowing me down. So I disabled the usb 2.0 controller (couldnt find floppy) which was stupid because I had a usb keyboard (I thought in the worst case I could plug it into the usb 3.0), this time when I tried to boot it wouldn't detect my keyboard and there was no way of me going back into BIOS to change back to default, so back online I went and found that I could reset the cmos, so i turned it off, removed the cmos battery for a few minutes and put it back. It started, then restarted, and it was working.
Eventually I ran into another problem and needed to reset the cmos again, but this time when I tried to start my computer the screen would remain black, the computer would turn on, leds and fans all on and spinning, including the psu,cpu,and gpu fans. It would stay on for a minute and then turn off for about 2-3 seconds and turn on again - now it just repeats this process over and over.
I have no idea what I could've done wrong, I tried to be as careful as possible, always touching a piece of metal before handling anything, placing components on that anti-static plastic stuff at all times (the stuff thats comes with a motherboard). I took out my psu and tested it in my older AMD machine and it worked fine, so I don't think it's that. However since none of the other parts are compatible I don't know how I can test them.
Is it possible the motherboard is bad/got fried? How would I test that? All the fans/leds that are plugged into the motherboard turn on and spin during the short time the computer remains on, does that mean it's still okay? BTW I don't have a case/motherboard speaker so I can't hear beeps.
