First of all, you do not have enough RAM. Make sure you can insert two RAM cards of the exact, same FSB speed. It is to make a Dual Channel synchronizing effect. 2 cards at 2Gb each(total of 4Gb).
Second, make sure your graphics/video card is in the PCI-Express x16 expansion slot. And, it has a minimum of 512Mb of graphics/video reserve RAM processing ability. Power connectors to it also.
Third, a good PSU of 350watt is recommended and, required is some cases. Mainboard has to me grounded via the interior of the case.
And, that the case has a very good air intake + an additional ventilation side panel air intake fan. CPU plaque has its on top of it's cooling fan. The graphics/video card came with its own embedded fan for its own cooling of its own processor. Make sure they are, also, plugged in in their respective connections onto the mainboard.
Reason: These new computers generate an enormous amount of heat. Therefore, the overheat safeguards might autoshut it down right away as soon it detects too much heat generation coming from it all.
Fourth, plug the main power connector cable to the main outlet of the mainboard's power distributor(should be a 16pin one). Connect the optical drive to the SATA connector and the Hard-Drive to the other SATA connector of the Mainboard. Note: make sure the PSU switch is at off position before plugging in the main power cord to it. Using a surge protector multi outlet pad, plug the whole thing in(exeption of the monitor one. Connect all other sound system, keyboard, mouse, gamepad and, printer hardware units, in.
Fifth, power on the monitor to see if it is in stand by. So, it can tell you if there is no signal coming from the PC machine's video port. Power On the main switch of the PSU. Wait a few seconds and, use the front of the case's main power switch to power it all up.
Sixth, you should see a very brief response from your DVD drive's LED light and, next, the Hard-Drive's LED light. You might have to force the DVD drive to do a let go of its disk tray via the emergency eject button right next to the standard self powered button of disk eject/insert. Or, just try the drive's eject button. Once open, insert your O.S. disk and wait for its autorun program onto it for loading up in memory of your machine's setup files to, now, run, and start the O.S. installation procedures.
Hope this post guides you through all this hard procedure of setting up your own, latest, rig.
