X51 R?, startup issues

Question

Iv had my computer in storage for a good while now and Iv decided to start using it again. I got it out of storage and plugged everything in and started it up. I got five beeps and a blank screen. I remembered that i always plug the hdmi cable into the wrong port. Easy fix. I start my pc up again and I got to my login screen. My computer has been offline for a while so I was going to connect it to the internet via WiFi to regain connectivity before logging in. About the time I’m connecting to my router my computer shuts off, restarts three times. Turns on and says your pc has ran into an issue collecting data. After the data was collected the pc restarted again then shutoff again. So I manually turned on my computer and the power light comes on at the powe button but the Alienware logo doesn’t light up nor does the  ambient lights on the sides. Iv did a power drain and nothing works. I can’t even get a screen to put it into recovery mode.
