I was having wifi problems so I restarted my pc and when it came back on, the login screen showed up and after a few seconds it froze and the screen went black. This keeps happening and I can't get into my desktop without it crashing. I'm currently in safe mode with networking and the event viewer shows 4 critical events called Kernel-Power Event ID 41 Task Category 63. I have already tried replugging my ram, graphics card, power supply cables and clearing the CMOS. If anyone knows what's happening please let me know because this is very frustrating.
