Pc turns on, however no display on the monitor

[ReefGoudswaard]

My dad had an old server pc laying around, and I asked him if i could have the pc and then upgrade it (since the motherboard had two sockets, i wanted to put another CPU in it). In the pc was a single Xeon e5504, however we then replaced it with two used Xeon e5640's which we bought from ebay. These cpu's were the only thing left to finish the pc, since the rest was already inside the pc. So I installed everything and was excited to turn it on, maybe update the bios, and then see how it would perform. When I turned it on the fans started spinning and the lights on the motherboard turned on, however when i plugged the VGA cable into the motherboard and then into my pc, there was no signal. I already did some research on this and someone said to try and clear the CMOS by pulling out the little battery thingy on my motherboard and then reinstall it 15 minutes later. I tried this and there was more bad luck, as now when I turn on the pc the fans won't spin anymore at all, but some lights did turn on on the motherboard. Does anyone know what is wrong? Or am I missing something very stupid? I already tried different monitors so i don't think it is that, however I havent tried replacing the cable yet because i don't have another one laying around. Also a side note, I am using 2 different CPU coolers, since one was already in the pc when i got it, and the other one (Hyper TX3 EVO) we purchased. Not sure if that would make any difference.

 

PC specs:

2x Xeon E5640

Asus Z8NA-D6C motherboard

24gb of ram

650 Watt Corsair PSU

The Xeons you put in don't have built in graphics. You'll need a GPU of some kind.

Probably not. You should be fine once you get a GPU in there. Be sure to check the BIOS and set everything correctly.

No problem. You'll find that a lot of Xeons (maybe all, IDK) don't have integrated graphics adapters.

I still have one more question: I cleared the CMOS by removing the silver coin battery thing and then reainstalled it 15 min later, however when i now turn on the pc the fans will not spin anymore at all. Do you know why? Because if found that a bit strange.

I'm not sure. Try reseating the RAM and the CPUs.
