No Picture & Continuous reboots

[Alpacr]

Hey guys,

 

a friend of mine and I started to build his Worksation today. Everything went fine, until the final assembly. Specs:

• Threadripper 1920X

• Asus Prime X399-A

• 64GB Corsair Vengeance LPX DDR4-2666 Quad Kit 

• 2x Gigabyte Vega 64

• Corsair H150i Pro

• 1200 Watt Corsair HX1200

I installed the necessery parts (MB, RAM, CPU, Cooling) and plugged everything in and checked if everyting would start up (no monitor yet), everything went fine, fans moving, LEDs on etc.

After the final assembly and proper cable management everything still went fine, but I couldn`t get a picture (no BIOS) and the DRAM-Debug-LED was on. I did some troublehooting with the RAMs and ended up in a bootloop, where everything lid up and started running for like five seconds (fans) and went off again, still no picture. I tried different RAMs and different slots, checked the PSU connection but no success. A CMOS clear wouldn't help also. When I dis- and reattached the CPU, the PSU appearently died, because after that, nothing would happen, except for the MB RBG-LED lighting up. I'll change the PSU as fast as I can, but IMO that doesn't explain the first problem. Since the PC is at my friends house, I currently can't get any pictures...

 

Can anyone help me?

MAKe sure its in a grounded plug, almost sounds like some part has an issue but not for sure. FROM NOW ON ONLY TEST with one ram stick in first slot. DO NOT plug in any hard drives or SSD, if something is fried they could also be hurt. Validate the power supply or use one you know works, only use one graphics card and if you have a test card you can use use it instead. Make sure motherboard screws and standoffs are all in, make sure cpu fam socket is populated, check for gunk in cpu socket, make sure all pads/pins make contact and the socket is tight enough, everyone says threadripper takes some OOMF to tighten on.

Yeah, tried that already.

That's the next step I'll take. I hope nothing is damaged already...

Absolutely. I tell you it's a pain in the a** to tighten these three screws. That's also the reason i tried to reattach the CPU once, but after that everything went even worse.

THough I havent heard about any problems overtightening on threadripper it could still be a thing, I have had a computer refuse to boot  at all untill i loosened the cpu mounting screws a quarter turn
