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.
I’ll try ya’all suggestions! I am just getting off work from a 14 hour day. I don’t have a working PC at home. I’ll check back with you soon (like Sunday or maybe next week.)
Thanks to all.
strip it down to bare bones. Use the onboard video.
If it doesn’t work then, it’s probably the motherboard or CPU.
Also, check to make sure you don’t have a trace or something on the motherboard touching ground.
Cheers
Yeah, that board has an onboard graphics card. You should yank out the one you put in and plug your monitor into the onboard video to get your machine up and running. You can put it back in later if you want. Also check that 4-ping plug into the motherboard in the pic above.
If you turn your machine on but don’t see anything on the screen, watch your keyboard as the computer boots up. If you see the lights on your keyboard blink after you turn it on, there is a good chance it is booting but you just aren’t seeing it on the screen.
Look just to the SW of the KB/PS2/USB(8/13) on the board.
Remove the video card. Load the drivers for it before installing it while using the on-board video. Check that the memory sticks are well seated. It sounds like the Power Supply loopback is ok. Make sure all screws are tight as the serve a return paths. The default settings of the bios should’t be an issue right now.
I need you to lay hands on my computer.
How much do you charge for over the net help?
Also, if you get a successful boot-up insert any CD’s that came with the board first. Load the files in the order they are listed and re-boot after each one.
Should I load the motherboard CD before I load on windows?
No, windows will do the management of the CD. I didn’t realize you have a clean hard drive.
What version of Windows are you loading?
You can do that? No wonder my systems never booted. LOL
I agree with the beep diagnostics. That's the lowest level of troubleshooting. But that won't work unless he's hooked up the speaker to the motherboard.
The speaker is built onto that board.
It’s an old Dimension 2600....I don’t even know why I bothered setting the thing back up...I think I felt sorry for it or something.
The DIMM contact being screwed up might have been the problem. That’s a good call. No matter...I’m using the old DDR in another system anyway.
I am loading Windows XP 64 bit Professional.
Do you have your video yet?
I am not at home yet. I am posting this from the gym right now. Just collecting the needed data. I’ll be messing with it soon. I do not have a working PC at home right now.
Doing some kettlebell swings. :-)
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.
aa
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?
