I am building a new computer. When I go to turn on the system it boots up fine and all the fans spin but I do not get any video displayed on my monitor. I don't even get the bios screen. I am running a 400w athena power supply, a asrock v88 motherboard, one stick of 512mb pc2700 memory, a 400GB seagate hard drive, a P4 3.4 ghz proccesor with hpyer threading that is a 775 chipset, and a nvidia geforce 4000 video card with 128mb of memory. I was wondering if the motherboard is possibly fried or my power supply is to small.
There are a few things that you need to consider:
1) An Athena power supply is considered very weak, underpowered, and of a very low quality, so I doubt if it is strong enough for what you want, and it could cause this problem. If it works perfectly, it may be too small and not have enough power to run this unit. (a quick way to find out is go to best buy or staples and buy a good one either an Antec or Enermax (expect to pay 100 bucks) in the 500 plus range and if it works, keep it, if not, take it back for a refund) Do yourself a favor and don't buy a cheap power supply....only an Antec or Enermax is needed.
2) When nothing shows from the video card to the monitor, the video card is always suspect or maybe not compatible with how things are on your computer. If you have access to another one via a friend or someone else, you might try another one to see if that helps.
3) There are some motherboards that require one to upgrade the BIOS before they will work with some of the newer processors. I am not familar with your board, so don't know if that is true in this case.
4) I seriously doubt at this point in trouble shooting that you need to think about the motherboard being dead, but that does not rule that out. Just that the probability is not too high until you have other things checked out.
Now the questions:
Do you have the ATX and the 12 volt square molex both connected?
Do you have the Heatsink fan connected to the motherboard.
Do you get a post beep when you start up the computer.
If you don't turn off the computer, does it reboot or just sit there without a display?
Is the memory you purchased on the QVL list for approved memory in your motherboard manual?
Anythng else in the way of information that might helps us to know what is happening.
