Problem with the first PC build not turning on
Problem with the first PC build not turning on
Hello everyone,
I assembled a PC and ordered both new and used components:
R5 3600 (stock cooler) – used
16GB Corsair Vengeance 3600
Gigabyte B450M DS3H – used
Samsung 970 Evo Plus 1TB
Corsair RM750 – used
Elsa RX 5700XT – used
DeepCool CH370 Case
After putting it together and turning it on, it didn’t work. I checked the power supply connection and everything seemed to fit properly. All cables were verified as well. I swapped the RAM slots and still couldn’t get it to boot, so I completely disassembled it. I placed the mainboard on a cardboard and connected only the 24-pin power, 8-pin CPU, and GPU connectors. Then I bridged the PowerSW pins in an attempt to start the PC, but nothing happened again.
I tested if the power supply was dead using a paperclip test—it worked, so there’s no issue with the PSU. The GPU had been checked at the seller’s place; it didn’t start with or without the graphics card, so it should function as well. The RAM appears to be in good condition since it came from Amazon and is new. I’m certain the processor is fine, though I wasn’t able to test it on-site. The SSD also seems to work.
I tried using the CMOS method, but it didn’t help. Is my conclusion correct that the motherboard might be dead? If so, what steps can I take to confirm or fix it? Since the board was purchased with buyer protection, I should be able to get a refund if needed.
Thanks for your attention, and I hope you can assist me in some way.
To confirm your RAM is in good condition, don't assume it's perfect just because you purchased it new from Amazon. Begin by testing a single stick to ensure proper functionality upon arrival.
I just take it to a shop for them to fix it. Often, figuring out the issue means swapping in a known good part, and they'll have replacements available. Don't lose hope—persistence wins, and we only grow when things go wrong. I've been in electronics since 1963 and still face challenges sometimes. It's part of the learning process.
