Unless your pc case is plastic inside do not just place the motherboard in there! The bottom of your motherboard has a lot of electrical contacts on it and placing it on a metal surface would short all of them together. When you are having trouble with a new build we suggest "breadboarding" . This eliminates the possibility of a metal standoff causing some sort of short, it is pretty easy to put a standoff (which are usually metal) in the wrong position where the motherboard is supposed to be mounted.
Have you tried just connecting only the basic required items? Power supply 24 pin to mobo (short for motherboard), 8 pin power connector to mobo, cpu installed with heat sink installed and no ram at all. The fan for your cpu heatsink should also be connected. When powered on it should beep 3 times due to not having any ram plugged in. If it does beep then add 1 stick of ram and try again.
If it doesn't beep without ram installed then your mobo or cpu is bad.
Hi there. As per the other forum post that l linked to, l breadboarded with mobo, cpu, cooler, cooler fan, GPU, RAM, but i removed GPU and had 0 RAM, 1 RAM stick, 2 RAM sticks then all 4 RAM sticks. I got the 3 long beeps until l stuck all 4 RAM sticks in. Feel free to comment on that thread.
My case = Corsair CC-9011075-WW Carbide Series 100R Windowed Mid-Tower ATX Computer Case - Black. It has little bumbs on the dark side of the case, each bump crested with a hole. I believe these are the "standoffs", into which the motherboard is screwed.
Honestly l don't know why they don't just make all cases plastic, if shorting is such an issue?
I see your mobo doesn't have integrated video so you will need to plug in your video card. Also make sure to connect the 6 pin power cable from the powersupply to the video card. If no video card is plugged in the pc should gives 8 beeps at power on if I remember right.
Yep l did all that
On your heatsink look here at the reviews http://www.newegg.com/Product/Product.aspx?Item=9SIA6J332N5915
One person stated that it is easier to install if you pop off the fans first, then pop them back in after. Another review says to be careful with installing it as it could brick your mobo, he says it is difficult to install and he messed up his mobo by doing so.
Damn. What l don't get is how on earth he sussed out the problem?
My cooler came with a CPU backplate, but l don't use it, because according to the instructions, there is no requirement for it with my LGA 2011-3 socket?
If l shorted the mobo, surely l wouldn't get consisted beep behaviour, and then zero beeps when all 4 RAM sticks have been put in?
You posted this: The DVDRW is connected to the USB 3.0 header on the mobo.
But you also posted it is a SATA DVDRW, I am guessing you made a mistake here, I don't know how anyone could even get the cable to connect but I have seen some
really crazy things before!
Oh no that was a mistake. The front panel features come out in 2 sets, Set 1 = lots of small leads for Power Switch, HDD LED, etc. Set 2 = the big 20-pin USB 3.0 cable. I believe both need to go into the mobo.
I mistakenly wrote that it was the DVDRW that the 20-pin cable was coming out of, but it was actually the section just above it, the front panel features.
Anyway, l've now put the breadboard away by inserting it into the case.
It was very risky, and to avoid dropping the mobo into the case, i had to, at times, hold the mobo at least partly by the CPU cooler.
When l connected everything up, the computer would not even power up. I changed power lead, still same problem. I then realised l had the computer on its side and l was pressing the Restart button instead of Power.
So anyway, back to the same issue as stated in the other thread, linked to in the OP: PC powers up, but no video output. I've ordered a cheap video card, hopefully it will arrive soon.
(so that l can test to see if the replacement GPU works)
