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.
tech help ping.
I hope you didn’t put a stand off in the wrong place.
What is a “stand off?” Where is the right place to put them?
The mother board was not damaged by lack of a GPU. I’d check seating of all components and then I’d find someone local with a bit more experience to help you along. Or vice-versa. Don’t take it the wrong way... build your own is great, but there are a few tricks.
Sounds like it could be ram. Try removing two sticks of your ram and see if that works.
a stand off is the little metal pedestals that clip onto the case and hold your mother board out away from the case. If you have one in the wrong place, you can burn a hole in the board circuitry.
Time to contact a pro.
Does the motherboard come with its own graphics card? If so, I'd plug into that before attempting to get the GeForce working.
I am pretty sure I have that wire connected.
Does the mobo/cpu have integrated graphics? If so try plugging the monitor into the integrated graphics output. I just went thru something very similar. IOW, you may be getting graphics output and just not knowing it cause you’re looking at the wrong port. Systematically plug your monitor into every place that supports it and see if there is output.
Are you hitting F2 while the system boots?
Looks like that mobo has onboard graphics, so you need to disable it to use your video card.
You may need to check and see if your memory is compatible with that motherboard.
Are you sure you hooked up power to all the right points? Mother board (possibly more than one place), HD, CD/DVD drive?
I have an old Dell Dimension which I put back into service after sitting for a couple of years. I decided to put 2 X 512mb’s of ram in instead of the pultry 256 I had been running. Guess what? Same symptoms that the OP had. No beeps at all...fans would power up for a couple of seconds, then go off, then come back on. In my situation, I swapped the Partiot PC3200 out with some PC4800 I had....and the system booted up. It surprised me too.
2)Remove and reseat the BIOS battery. If you have a voltmeter, check to see if it's bad (boards occasionally ship that way). You can otherwise put it on your tongue to see if it has a charge - unpleasant, but effective.
3)Get out the installation guide. Check your jumper settings.
4) Install one - and one only - bank of RAM, and the processor. Do NOT strap in any drives, USB headers, expansion cards, or anything else.
5) Make sure your power supply is connected - P1 and P4 cables. Plug in your keyboard, monitor, and mouse, and boot up.
Umm, the standoffs are usually plastic. They are plastic cylinders used to mount the mother board.
