Re: No power to motherboard

If there is no power to the motherboard then there would be no power to anything else. I can only assume that everything (HDD and DVD Rom) comes on but your monitor remains blank when power is turned on. How do you know that the processor is on? Im guessing that you assume because the cooolant fan starts turning then there is power to the processor. Unfortunately that is not the case. Your Processor could be the problem try changing it. should the speakers be emitting beeping when the computer is turned on then try changing your memory (RAM). If none of these are working then try installing a VGA card into one of your PCI slots and plug your monitor on the VGA card. If none of these work then you Mboard needs to be replaced as it could be damaged. let me know how it turns out then I will let you know what to look for in terms of damages. thanks

Unable to find the power switch to connect to

If you no longer have the manual for you're Intel D815EEA motherboard, open the link provided and download it;
You will also need Adobe reader installed to view the manual;
Read over pages 65 to 68.
Once completed turn to page 68 Figure 23. Front Panel connectors. Figure 23 shows two views.
View - (left figure), shows J9C1 as you look down at the front panel pins. The right figure will not be needed. Connect each jumper or each pair as shown.
Wire colors are important and do vary from case to case. The common color of each pair will most likely be used for negative. Wire colors such as blue, light blue, green, light green, red and light red are commonly used as positive.
Pin 1 will be positive and pin 3 will be negative. This is letter - C. Hard drive activity LED.
Pin 2 is positive and pin 4 is negative. Case power LED, and so forth.
As mentioned on page 65, the case front panel pins use 5 volts DC. If you make a mistake and place a jumper backwards (No LED light), just power off the switch on the back of the power supply and correct the jumper by turning it 180 deg. If you’re case’s LEDs do not light up than you will need to connect letter G and letter H. The electronic circuits under the motherboard should supply all 16 motherboard pins with the 5 volt DC and ground needed.

I can not find the matching pinsforthepwsw hdd led

Open the Intel link provided;
Create a folder on your desktop and name it, Intel D815EEA
Download the file named, "" in to your Intel folder. The *.zip file must be uncompressed. You can download and install a 45 day free trial program called WinZip. Download WinZip from here; the program named Winrar will also uncompress the file;
Once the either program has been installed open the Intel folder. Right click once on the file *.zip and from the pop-up window and click, Extract Here. You will need Adobe reader to view the PDF file. Adobe is free;
Open the PDF folder. Open the "A1696401.pdf" file. This is the manual for your D815EEA board.
Open to page 69 motherboard layout. Item "C". Find pin 1. You can zoom in with Adobe by clicking the + sign in the tool bar. Than go to, Table 48. Section page 71 in Adobe.
Front Panel Connector. Example:
Pin 1 is power for the HD_PWR = Hard disk drive, Power LED. Pin 2 is ground for the HD_PWR. ECT...
Case wire colors vary. Normally the solid colors red, green, blue and green are positive. Except black which is usually ground for the internal speaker.
The wire color solid white is usually - negative. So each pair will have a common wire color used for negative.

Hope you find this helpful.
