Computer wont boot up

I can get as the first screen that shows my motherboard brand. Then it freezes up and I cant get anywhere, not even the BIOS. I had this problem yesterday but all I had to do was put the RAM in different slots and it booted up again. But earlier today I reset my computer to update software and I have the same problem. I switched the RAM around again but I think all my ports are dead. Is that actually the problem or is it something else? And can I fix the problem?

You need to reinstall windows to get rid of all the viruses
