I have a hardware question. I just now installed a new motherboard. When I powered it up, the fans came on and so did the mouse, but I did not hear beep and my screen was blank. What did I do wrong?
this motherboard, it is from intel - a DG43GT iG43
Into this motherboard I put an Intel Pentium D 945 3.4GHz 800MHz 2x2MB CPU. I then added 8 GB (four 2GB sticks) of OCZ brand ram, and put in a OCZ brand silent power supply (500 watt) and a GeForce 9800GT graphics card. All of that stuff was new. I can only guess if I seated all that stuff correctly.
On more little detail. When I first turn it on, the fans turn on - but then after 2 or 3 seconds, the whole thing turns off, then it comes on again after about 5 seconds. Is that a short circuit?
Also, I have never had a graphics card installed in my system before - so I now have three different ports to plug-in my moniter. So I just guessed which one to use and picked one the back of the GeForce card.
I did not put a modem in it, as I do not plan on using it on the web. Would that mess anything up? Do I need a modem?
Any advice is useful. I hope I do not have to take into the computer shop. They charge $70 just to look at it.
I am going to by a PCI test card to tell me what is happening in the BIOS. I'll become an expert on this - I spent too much money on this already!
The first time I turned it on, I did not have the GPU connected to the power supply. After I connected it, the same thing happened. It powers up, fans on, no beep, 2 seconds later it turns off then tuns back on 5 seconds later, with fans but without beep.
Could I have damaged my motherboard powering it up without the GPU connected to the power supply? Drats.
I burn incense and spread chicken entrails on the BIOS.
Intel build yer own bookmark for later reference.
Screams 'memory problem' to me. Check the memory type, make sure they match and then remove and reseat them. Worth a shot.
I tried a few things once I got home. First, I disconnected most everything from the motherboard as Viking2002 recommended, and then pulled out all but one of the ram sticks. Rebooted it. Fans came on, no beep, but it did not turn off again.
I then went to bed. I will mess with this later.

Now, having spouted all that gibberish, there's a damn good possibility that you just got a bad board right out of the box. It's happened to me more than once. I'd check and see what sort of consumer geek rating that model has - there are quite a few that spec out nicely and look good on a web page, but aren't worth the cost of the shipping to send them. Give it one more shot - if it still won't boot, return it and get a different brand.
Okay, one bank. I’ll try it.
Tried one bank, in O and 2 spots. Same thing, fans on, no beep, it turns off, turns back on, still no beep.
Tried anouther brand RAM (I bought it for my Dad’s PC) same thing.
So I should return the Motherboard and get my money back?
This board seems to work! There is no beep, but that is because my case has the speakers and its connector does not fit the one on the new board.
However, something strange happened when it booted. As it goes through its boot phase, the keyboard is dead. I cannot hit F2 or delete or any other prompt to let me reset its Bios.
It then loads up windows xp, with everything intact from the old hard drive! I would like to keep that! That is good. I thought I would need to reload windows.
But the mouse and keyboard are not operating. I tried all the USB connectors on the front and back of the case. The mouse lights up, but it cannot move.
How do I get the mouse and keyboard to wake up? If this is a Bios problem, how can I talk to the bios without a mouse and keyboard?
Thanks for all your advice. :-)
Do I need to do anything like “flash” the bios or “reset the bios clock” - I don’t want to jack around with this.
First, I tried using an older keyboard and mouse (ones with the round hole and the pins in them) and they did not work either.
So I did that thing with the battery, and the keyboard works during the boot!
I went into the BIOS and told it to enable USB keyboard and mouse. After that, the mouse still did not work.
I took the battery out several times, and still the mouse is dead. Also, the keyboard seems dead after the boot - when windows wakes up.
What now?
