So I was assembling my new pc, it has an intel pentium g3258 socket 1150, the motherboard is an asrock H81M-VG4 R2.0, and I have kingston´s hyperx fury 2x4gb at 1600Mhz, and a MSI radeon r7 250x, and everything was running as normal as possible i´ve entered bios to check if everything was ok and it was and turned the pc off, because I was waiting for my disc to arrive, as soon as I got my disc (transcend 32gb ssd) i´assembled it on the bracket an connected the supply cable (I forgot to connect sata cable) and since then I can´t have no video output from my machine... i've reseted bios i have started it with 1 dimm with the 2 dimms with another cable and monitor etc i've done everything including online guides and etc... but it still has no video, it turns on, stays about 1 or 2 minutes on (no video) and the reboots doing the same thing all over again, and the power led becomes red as it reboots, normal color ir blue,,, can somebody please help me out?

The most common cause is a power to ground or data to ground fault.
Unplug everything from the motherboard including the video card and the memory. Try to power it on. You should hear a series of beeps indicating a missing video card and memory error. If not, you may have a bad motherboard. Install the video card and one stick of ram and try to boot. Shut down and add a stick of memory and try to boot again. Add each device one at a time and boot up to see what the cause was.

Without the dimm's and vga i get a boot but when i install one dimm or the vga it starts then shuts and then starts again... and then reboots... and does it all over again.. the problem is not the dimms or the vga cause i've tried them in another pc and they work... so the problem must be the motherboard...
