No video output on boot?

[Xeypax]

I'm building a budget PC to have in addition to my main PC, but it doesn't output any display even after testing every output available (including the MB).
The parts: 

•  Old Dell case

• MB: MSI A88XM-E35V2 (new)

• CPU: AMD A4 7300 Dual-core @3.8GHz (new)

• PSU: HKC USP-3430 430W (used)

• HDD: Some Seagate 1TB (used, but working)

• RAM: Some kingston 2*4GB kit (used, but working)

• GPU: Gigabyte GeForce GTX 960 2GB ITX (used, but working)

 

What I've tried:

• Swapping the GTX960 with one of my MSI GTX 980
• Swapping the RAM with a 16GB kit from my main PC
• Swapping the PSU with a Corsair HX1050 
• Booting without the graphics card
• Booting without a storage device

I feel like I've tried everything, so any help is much appreciated.

Had a similar problem two years ago on my old budget pc. (i think it was a fx-4350 and a radeon r7 200 series.) 

 

Try to remove the RAM, clean the RAM and socket from dust, and put in again. 

 

Worked for me multiple times.

I tried your advice, but without luck. All the fans start spinning and the HDD is making noise, but there's still no display signal.

There is no BIOS sound, is there?

I didn't get a speaker with it and there aren't any lamps on the board. Also, speaker from my main rig doesn't fit with this motherboard.
