Question about Intel D915PCY Motherboard

Computer won't power on at all when network card is plugged into motherboard

This is the first (and only) computer I ever built. I have the Intel Desktop Utilities installed on it, and when it sets off the alarm for processor getting hot I clean it out. It has worked for 2-3 years now. However, after cleaning out one time it started displaying this symptom: when shut off, it won't start the next morning until the power button is pushed over-and-over...sometimes two pushes starts it, and sometimes 50 pushes. On someone's advice, I unplugged everything from the motherboard and tried starting unit - started on first push. Plugged in devices one by one until it wouldn't start. Found that when network card is removed from motherboard, unit powers up on first push of power button every time...but when card is installed problem occurs. Any ideas?

Based on what you said, network card is not the main problem it is on the expansion slot where you had put the network card. My advice is that you should try putting your network card on other expansion slot or try another card (which is working) and put in on the slot to where you previously put your network card and if it doesn't work, that slot may have been damaged or it may have dirt inside.

Have installed windows 7 but having probs with VGA ... There is none ....

This motherboard has Intel graphics built in. I assume you were using a PCIE or PCI plug-in graphics card which is not working since you installed Windows 7. Swap your screen to the built-in VGA adapter on the motherboard and re-boot. Then download Windows 7 drivers for your video card. If this is not the problem, go to your BIOS settings (if you can) and reload default settings. If that doesn't work, plug a known good VGA card into an expansion slot and re-boot. Then proceed as above. Never add or remove cards while the computer is plugged in to power. Good luck!
Cheers, Don

Computer won't power on right away

Wll it could be your pci controller is damaged.. (In thic case the only solution is to buy a new board)

Or you bios might need flashing..

Unplug your system
Open up the system,
put back in your network card
remove the battery on the main board
hit the power button 7 times
replace the battery
plug it back in and try to boot now

When it boots, you need to enter the setup and load your default settings then save and exit..

I replaced a video card... now the computer won't start at all

did you move any power or data leads around
is the video card a new one that is compatible with your motherboard

check all power and data leads that attach from motherboard to hard drive for secure dust free connections even a loose fan lead connection can cause you problems
if its a 40 pin flat ribbon ide it will be suspect

also check the video card socket for dust and for compatabilty

hope this helps

How many MB or GB graphic built in intel DH55TC mother board? i mean to say how many graphic are built in intel DH55TC mother board?

The motherboard has a built-in graphics card and it uses shared RAM. It uses part of the main RAM memory and the main computer memory is reduced by the amount of RAM the graphics card grabs.
You can limit the amount of RAM the graphics card used by configuring the graphics RAM in the BIOS configuration.

Just built up a new system with an Intel DP43BF I can't see any Video to set up the Bios by hitting F2 the Video card is a PCI Express X16 Gforce 9500GGT Tried using a PS2 Keyboard and no luck


Please try removing everything that is plugged into the board except for power and the processor and processor fan, then try to power on the computer. Also, please check and make sure that all applicable power ports on the motherboard have power supplied. If you don't get any beep/error codes at this point, you can assume that the board is dead. If you do get a beep/error code, please let us know so that we can better help you diagnose the problem.

Thank you.

Mm, my PC didn't turn on and I open de case and I coul see that it had a lot of dust and I cleaned and then It turn on normally. But when I turn on the Pc doesn't detect the netword card, so I can't...

If you have an OEM network card that you installed yourself, then we'll need it's make and model.

If you're referring to the onboard LAN functionality built into that motherboard, it's a Realtek 8201BL PHY

If you have another computer that you can download the drivers on, and then bring them over to this one by usb, you can download the drivers for your motherboard's built in network port from the website below:

Built in network drive is not working can i use a network card?

As long as there is an open PCI expansion slot, you can plug in a network card. You can also use a USB Ethernet adapter (here's an example) if you don't have a slot available or you don't want to bother opening the computer case. Just remember to go into the BIOS settings and disable the built-in network interface so there won't be any conflicts.
