I just got all the parts for my 1st PC build a few weeks back and It won't POST. Reseeted every connection, used 1 stick of RAM, used 2 Sticks of RAM, used internal graphics, and even got a new motherboard but nothing shows up on the screen and my keyboard won't light up.

CPU: AMD A8 9600

GPU: Nvidia GT 1030

Motherboard: 1st one: Biostar A320 MH ver.6.x

Motherboard currently: Gigabyte A320M-S2H ver.1.2

RAM: G.Skill Ripjaw 5 2X4 GB 3200

PowerSupply: EVGA 600 BR

SSD: Samsung EVO 870 250GB

Power supply working? 8 pin Molex connected?

@imicrosoldering Yes everythings connected and the fans and RGB turn on but the fan Ramps up and down

@pikapika3092 If that’s the second motherboard I would use some magnification and check for a bent CPU pin, not much else it can be.

Try connecting a pc speaker (example only) to the header pins on the motherboard (see image below for location on Gigabyte motherboard) and check if there are any beep error codes

I realize that the problem has occurred with two different motherboards but it is one way to find out what may be happening

Also do a paperclip test on the PSU to make sure that all the voltage supplies are OK.

@pikapika3092

No beeps means that it may not be even starting POST

Did you test the PSU or check the CPU for bent pins etc as suggested by @imicrosoldering, you didn't say?

完成的
