New Homebuilt PC - No display

Hey everyone.

Today I got my brand new PC parts delivered from Aria and after spending quite a long time checking everything over and putting it together (not prebuilt) the monitor wouldn't display anything.

The monitor is FINE. I tested it with another PC and it worked. I also tested a different monitor with my new PC and it didnt work either.

The motherboard beeps with no RAM in the machine, but it doesn't beep when there is RAM.

Yes, the power supply is connected to the motherboard correctly.

System specs are as follows:

Motherboard: MSI Z87-G43

Graphics Card: XFX Radeon HD R7850

Power Supply: CX750

Processor: Intel Core i5-4570 3.20GHz

RAM: Corsair Vengeance 2 x 4GB

HDD: 2TB Seagate Barracuda HDD

When the system is turned on everything runs perfectly (fans etc.) apart from the monitor which stays without a signal. The PC will turn on for about 30 secs, turn itself off, then run again. This does not repeat.

Any help would be greatly appreciated.

make sure the ram is properly seated in the sockets. I had the exact same issue with a Z77 board just the other day, and reseating the memory did the trick.

also make sure you have the monitor plugged into the discrete card's output, not the mobo output. if it already is, try the mobo output, as it may be the graphics card not working or being configured correctly.

if the PSU has a fuse, make sure it isn't popped. also turn off the PSU (the switch on the psu) and allow it to discharge (there will be no lights on mobo at all) and then give it another go.

most of the time when you're confident that the new parts aren't the problem, always gotta recheck those minor little things. happens to the best of us.

1. Tried three different sets or RAM multiple times, still didn't work.

2. Tried all the different outputs with and without things plugged in, also didn't do anything.

3. PSU is fine, tested it etc. etc.

Bread boarding it now, then gonna rebuild it if it works. Thanks for the advice though.

Worked it out. Due to XFX's idiocy I had to use the integrated graphics card to manually install drivers, seeing as the graphics card wouldn't auto install them. -.-

Also took ages because the XFX website provided no insight into how to get the actual drivers.

I knew there was a reason I always buy NVidia cards lol. glad you got it worked out, nothing more frustrating that having a whole new rig set up and something not working.
