Hey! So I built a litecoin mining rig, aka a very scaled back computer.
Got an ASRock 970 Extreme3 r2.0.
Put on AMD Sempron 145, connected heatsink.
Put in RAM (Crucial 2GB 240pin).
Put on GPU (MSI Radeon 7950 OC Boost Edition).
Connected cpu fan cable, cpu power cable, and both pci cables to the gpu.
Oh, and the ATX main cable.
Started it up. everything turned on after i shorted the power on header.
All fans running, so I had to connect a monitor to set up the BIOS.

Then, nothing.
Monitor turned on, went into sleepmode.
Monitor is confirmed to be working.
VGA/DVI adapter fresh out of the bag, should be working.
Radeon 7950 has its fan running, should also be working.


Any help?

So you have a GFX card along with the HD 7950 ? GFX is a Nvidia type of card. If you have two video cards then is the monitor cable connected to the correct video card ?

If you turned on the PC and after a few min. the monitor went into sleep mode then there is the possibility that the Monitor did not receive a video signal.
This can be the result of a bad cable , a bad adaptor , a bad video card or a motherboard problem. Do you have another video card to try in that first pci-e x16 slot ?

Wow, I worded that badly.
Only one gpu, radeon 7950.
The monitor isn't receiving a video signal, correct.
However, the adapter is new and the 7950 is receiving power.

There is no guarantee that even a brand new component is not defective.

Does the monitor auto recognize the input ? Do you have to set the input in the monitor menu ? Are you getting a bios POST beep confirming all components functioning and continue to start loading Windows ? Did you get into the bios ?

A no to the POST beep means something is not functioning , the Power On Self Test checks the CPU , the Ram , the video card and the hard drive. If all pass then you get the POST beep , if one doesn't then you get a different beep code to point to the part that failed , if no beeps then you either need a motherboard speaker or a motherboard.
