I bought a new case and and put all my old parts into it and it worked just fine before but now it won’t work. The gpu fans turn on for about 1” seconds then slowly stop. I’ve gotten it to post and even load my desktop but it’s very slow and didn’t show any icons. I’ve looked at other threads and made sure my psu is plugged into everything right and reseated my ram but nothing is working. Any help would be appreciated.
