I can't get my new build to power up.

I did't know where to put this, so I put it here. I'm building a new pc and the motherboard is a Aorus ax370 gaming k5 motherboard. I bought a new power supply for it and used the old hard drives from the old desktop, the old Blu-ray drive, and Geforce 1050ti graphics card. I hooked everything up the way the manual said and I didn't get any power. I used the old 1000 Cooler Master power supply that was currently working with my old desktop and couldn't get that to work. The new case was a cooler master master case and it was a little cramped, so I completely rebuilt everything on to the old case. The new power supply still wasn't working and the fan on the power supply wasn't moving. I switched back to the old power supply that was working on the old computer and now it's not working. The fan isn't moving on the old power supply. I'm completly frustrated with my second build. The first build five years ago was really easy and now it's complicated. I need some help with this one.

  2. First of all I bought the hyper t4 cooler master cooler which was compatible with an am4 motherboard and I couldn't figure out how to put it on. I put to much thermal paste and I kept banging it around the motherboard trying to get it on. I just tried to clean up the thermal paste on the cpu and cooler and reapply it. I got tiny little drops here and there on the motherboard I hope I didn't fry the motherboard or the cpu. I cleaned up what I could on the motherboard and put it all back together and still no power coming from the psu.

  3. Whats the CPU?

  4. If I fried the motherboard or the cpu or the psu is dead I don't know what part to replace I spent all my money for this month. Also I'm reusing two old hard drives from the old computer that has my English class information on it to write my final essay, so I need to find a solution ASAP. I accidently tore up the older motherboard so I can't rebuild the older computer, but when I built the first computer it worked. I don't know what's different with this one.

  5. The CPU is an AMD Ryzen 7.

  6. The new stuff I bought from Newegg.com. I don't know if Newegg dropped the ball or if its me. I can't return the new parts because I was buying a part a month.

  7. I would buy a motherboard speaker and see how many beeps you get

    So you connected the ATX12v, 24 pin, cpu fan. Did you install the standoffs?

    If you do manage to get it to turn on , you'll have to format the hdd if there's an OS on it. And do a clean install

  8. I got the standoffs from the older case. I've connected the ATX12v and the 24 pin, and the CPU fan. The PSU is not coming on at all either its a dead part or something is shorting it out. I was going to format the hdds.

  9. Take it out of the case / breadboard it. See if you can get it to turn on / post

  10. I'll have to wait till I can get a motherboard speaker which could be well into next week, but I'll try it.

  11. I've got the first link about preforming these first steps bookmarked, so once I get a motherboard speaker I'll be able to try those steps. I looked at newegg.com and they don't cost much.

  12. Hello, your motherboard has a EPS 12v instead of a ATX 12v, 8pins instead of 4 pins.
    Please let me know if you connected that properly first. The PSU wont run if you have connected something wrong. Also if you think there is some problem with your psu you can always do the paper clip test.
    Open all connections, take the psu out, remove the plug attached to your outlet. Take a paper clip or a wire, Find the green wire in the 24 pin connector and connect to any black wire. Now turn on the power without touching the psu. If the fan starts your psu is alright.

  13. Also i assume you have connected your front panel to your motherboard correctly. Please refer to the mobo manual for the appropriate pins if you think you might need a second check.
    Often the solutions aren't far fetched. I also staggered a bit while assembling my pc, and often times people like me make very easy to rectify errors, panic is alright. I also panicked when things did not seem to go according to plan.

  14. I did the paperclip test on the new psu and it is working. The fan is coming on. So I don't know what else it could be unless I fried the motherboard when I put to much thermal paste on it. I was trying to fit the air cooler on which is a Cooler Master Hyper T4. It was a bitch trying to figure out how to put it on and I banged it around several times trying to figure it out.

  15. I've been going over the steps I took to build the computer. I got a question. I looked in the motherboard manual and it said the memory had to be DDR4 DIMM modules and I bought DDR4 SDRAM modules would that prevent the motherboard from starting up?

  17. I got it solved for now. I looked up how to breadboard a motherboard and ordered a motherboard speaker. The website suggested using a screwdriver between the power leads on the front panel connections. It works. So I've been getting all my software and games on to the hard drives. I need a good suggestion on what to cover over the power leads, so to complete the circuit without using a screwdriver all the time. I can do a restart most of the time, but what about the times I need to do a hard reboot. I need to close the case so I don't have wires going everywhere.

  18. If shorting the pins works then something is wrong with the wires coming from the front of the case. Or the on/off button
