Hello everyone, i have just finished building my first build and as the title says i don't know why my system won't output any video upon bootup. I have an intel dp55wg motherboard, intel 660 processor, 750 watt corsair psu, and 8gb of patriot ram. I currently have the video being outputed through the hdmi port on my geforce gtx 460. the motherboard itself didn't come with an output port which is why i have it hooked up through my graphics card. can someone please help???

actually i've come to the conclusion that my comp isn't booting up in the first place due to the fact that i have a postcode error. Postcode 27 is described as "initializing memory", how to fix this i have no idea

Okay so I am assuming that you are going by the numbers being displayed on the two digit LED display on the motherboard and on that display you are seeing the numbers 2 & 7.

That error shows up in the owners manual as being: Configuring memory

Here is what I suggest, first I suggest you open your computer case, touch any part of the metal computer case first before touching any internal parts inside the case.
This allows any static electricity that may have built up in your body to equalize with any energy stored inside the computer case.

Next locate the RAM sticks and double check which slots they are installed in, specially if you have more than one RAM stick.

You have 4 DIMM slots on this motherboard.
Below I am copy and pasting what your motherboard manual states for this motherboard.

Main Memory
NOTE
To be fully compliant with all applicable Intel
SDRAM memory specifications, the
board should be populated with DIMMs that support the Serial Presence Detect (SPD)
data structure. If your memory modules do not support SPD, you will see a
notification to this effect on the screen at power up. The BIOS will attempt to
configure the memory controller for normal operation.
The Desktop Board supports the following memory and interface:
Four 240-pin Double Data Rate 3 (DDR3) SDRAM Dual Inline Memory Module
(DIMM) connectors with gold-plated contacts arranged in two channels
1600+/1333/1066 MHz DDR3 SDRAM Memory Modules
NOTE
DDR3 1600 or higher memory support on this desktop board requires
compatible XMP-enabled memory or advanced knowledge of BIOS and
manual memory tuning. Individual results may vary.
Support for single- and dual-channel memory interleaving
Unbuffered, non-registered single- or double-sided DIMMs with a voltage rating of
1.65 V or less
NOTE
Using a DIMM with a voltage rating higher than 1.65 V may damage the
processor.
Non-ECC DDR3 memory
Serial Presence Detect (SPD) memory only
Up to 16 GB maximum total system memory
NOTE
32-bit operating systems are limited to a maximum of 4 GB of memory.
These operating systems will report less than 4 GB because of the memory
used by add-in graphics cards and other system resources.


You may want to try removing the RAM sticks and replacing them back into the motherboard and making sure they are fully seated and locked into place.

Perhaps you made changes for the SPD in your BIOS setup utility, you can re-set that configuration simply by examining your BIOS setup screen for a short-cut key combination to re-set the BIOS to its DEFAULT setting or FAIL SAFE CONFIGURATION.
This will cause the BIOS to use settings that will allow a successful boot-up.

Are you sure the RAM sticks you are using are compatible with this system?

Did you change any of the timings or voltages in the BIOS for your RAM?

Bruce.

I went to Patriot's web site to see what was compatible with your motherboard and what I found is below, I wanted to link you directly but the site is not configured that way, so you'll have to check on that yourself.

http://www.patriotmemory.com/configurator/

But for what it is worth, I copied and pasted the text below, hopefully the columns fall into place below.

I tried to find out if your kit was NON-ECC--NON Buffered which is what your motherboard calls for, but I failed to see that at the link you supplied above in the specs.

Desktop Board DP55WG Media Series

Recommended Memory

Non-ECC Unbuffered

Part #-------------------------------Speed Capacity

PGV34G1600ELK------------------PC3-12800--(1600MHz)--4GB
*******************************************************
PSD38G1600K
PSD38G1600KH-------------------PC3-12800--(1600MHz)-8GB
*******************************************************

ECC Registered

Part #-------------------------------Speed Capacity

PGV34G1600ELK------------------PC3-12800 (1600MHz) 4GB
*******************************************************
PSD38G1600K
PSD38G1600KH-------------------PC3-12800 (1600MHz) 8GB



If the timings are to be correct, you would have to set them to 9-9-9-24 in your system's BIOS screen.


NOTE
DDR3 1600 or higher memory support on this desktop board requires
compatible XMP-enabled memory or advanced knowledge of BIOS and
manual memory tuning. Individual results may vary.

I contacted intel and they claim that the motherboard only supports ram with a voltage of 1.5 or less, when it clearly states otherwise on the website. and i can't tell if the ram is ecc or not. also, when i contacted intel we went through a number of troubleshooting tests, one of which involved trying to update the bios on the motherboard. anyway, nothing we did worked and now im packing the mobo back up to send to intel so they can test if it's defective or not. i really don't know what the problem is since the ram is made specifically for the chipset installed on the board
