I should start with a brief overview first, as you suggested. A colleague who worked with me recently assembled a PC a few years ago. Below are the parts I listed. He met up with a girl, but she wasn’t pleased about how much time he spent on the computer. The machine was moved from the living room into a kind of storage shed. After two years, I purchased it for $50 and brought it back home. I cleaned it thoroughly, removed any debris, and reassembled it. Unfortunately, I didn’t get anything useful—no updates or improvements. The power supply’s fan didn’t start at all. I thought I’d have to replace several components. I tried the PSU with a paper clip; it didn’t work. Eventually, a new PSU arrived, and I installed it. Still nothing happened.

The replacement PSU came with a tester, so I plugged it in and it powered on, leading me to believe the motherboard was faulty. I then bought a compatible CPU and motherboard from a friend. I got everything home and tried it out. Nothing worked. I left everything except the CPU and cooler in the case, leaving just one stick of RAM in slot A2. I adjusted the CMOS battery, but still nothing. I swapped the RAM sticks around, but it didn’t make a difference. This prompted me to search online, which led me to this forum—thank you for the helpful site. Here’s the list of components I used:

Gigabyte GA-970A-D3P mobo
AMD FX-8350 4000MHz 8-core CPU
G-Skill Sniper 8gb DDR3 1866 x4 for 32gb ram
Sapphire Radeon Nitro r9 390x GPU
Aresgame 550 watt PSU (~ I now realize it won’t suffice)
WD Black 1TB HDD
Cooler Master liquid CPU cooler (model uncertain)
NZXT case (model uncertain)

Use a screwdriver to jump the power switch pins on the motherboard. If you've been relying on the case's power switch, it might be faulty.

Aresgame are really bad power supplies. You need to get a genuine one.

That thought crossed my mind, but I'd prefer to hear it from someone more knowledgeable on this topic. Appreciate the help.

Did you rely solely on the modular cables included with the updated PSU? (And ARESGAME functions as a problematic PSU)

Well, thanks for your opinion but I've already established that the PSU works and even though its most likely uinderpowered for what I'll be using it for, It should still let the system post.

Yeah. Most people think about the PSU this way, but for now it's just what I got and my system won't post. To clarify, the PSU I bought isn't modular, so I had no option but to use the cables that came with it. The only ones I reused were those included in the case.
