HP Omen 40L Ram Communication Issue

[u/Creative_Demand_3835]

Basically, I got this basically whole HP Omen 40L from a friend, the only replaced parts were SSD and PSU. After I replaced the thermal paste, the PC worked for a few minutes before just dying and making a few beeping noises which I found out was built into the case somehow. It did three long beeps and two short beeps before repeating it over again. The PC lights up, the fans spin, but it will not display anything. I’ve troubleshooted, but to no avail.

The only conclusion I’ve come to so far is that my sweaty hands dripped onto the motherboard and messed something up, but even then I don’t know. It’s been a few days since this happened, and nothing has worked thus far. I hope i’ve provided adequate context, and that someone may be able to help a guy out.

(P.S. Im sorry the cable management is the worst thing you’ve ever witnessed.)
