Hey all, I went in to overclockers today for a new monitor and got a little bit carried away. Came out with a cpu, mobo and memory. Thought I'd try and salvage some parts from my old PC for a new build.

New parts -

Mobo: MSI B350 Tomahawk
CPU - AMD Ryzen 5 quad core 1500X
Memory - Corsair Vengeance LPX 8GB (2x4) 2666MHz

Old Parts -
GPU - HIS Radeon 7950
PSU - Antec TP 750

Got everything installed fine, turned it on and I'm getting no video output at all. No beeps, the only LED on the motherboard after the initial flashes is the one indicating that the CPU doesn't have integrated graphics, which I know it doesn't.

Working with an old Samsung HDD for the minute that still has a Windows 7 install on it that hasn't been touched for years. I know that will probably prevent me from booting properly but I assume that I should at least still be seeing POST visuals?

Anything immediately jump out at you as being wrong?
 
Well I didn't 'forget' to only install one stick of memory on first boot, I didn't know that was a thing at all haha. Still seems strange that that would lead to no video at all though? Any suggestions on how to fix?
 
Taken out everything except what you suggested, no change aside from the "boot" debug LED being on but I guess that's because there's no hard drive. Also checked power cables and reset CMOS, no bueno. Connecting with HDMI, the monitor connects to my macbook and displays no problem.
 
Was going to get a new GPU eventually anyway so I'll just bring that forward to Monday, will report back when I get it in. Cheers for the help.
 
Just had a bit of a breakthrough actually, I've plugged it into my TV instead of the new monitor and I'm now seeing BIOS. Good news I suppose? Now to figure out why it doesn't display on the monitor that works fine with my PS4 & Macbook...

Edit: It's already seeing both RAM sticks as a bonus too
 
If I turn the PC on while it's plugged in to the TV, then switch the cable over to the monitor the BIOS displays on the monitor as normal. If I switch the PC on whilst plugged in to the monitor, I get nothing. It's like the monitor isn't receiving the "hey, I'm turning on now" message from the PC.
 
No luck with the power thing. Going to install Windows and flash bios this afternoon. Reckon it's worth flashing the GPU BIOS too if it's still dead or is this more likely to be a monitor thing?
 
Yeah the monitor was bought at the same time as the other parts. Weirdest thing to me is how it DOES work with the monitor, but only if it's plugged in to the TV when I first turn it on. Can't wrap my head around that at all.

Erm... I think I've fixed it...

There's a setting on the monitor called "Game Mode". I turned game mode on, it still didn't work. I turned game mode off again, and now it's working...
 
I'm completely bewildered as to how that fixed the problem but at this point I'm ready to just accept it and not ask questions.

Yeah going to hold off on card for a while. Thanks a lot for the help.
 
Could well be. I can move the HDMI between Macbook and PC freely now and it works perfectly. Can also turn game mode on and off on both machines and it still works. Super weird.
