New computer .......

Bad news.... The memory sticks arrived, I installed them, but the system doesn't send out a signal to the video monitors. I tried two different monitors and two different video cards.... nothing...... can't even get into the Bios. It may be a problem with the motherboards, processor, memory, who knows.........rats.... The hard drive led light blinks okay, and the dvd burner seems to be working,  all fans are working, lights on the motherboard are working, but no video signal out or and no signs of life from the floppy drive.

Don't try this at home kiddies.

Bad news indeed. First make sure you processor is installed correctly. Double check any jumpers you might have to change or wires you have to connect on the motherboard. Then try to reset the BIOS (look in the manual for instructions how to do it). If that doesn't help, try to boot your PC with only one memory stick in different slots. If that doesn't help, use another memory stick from another  PC.

If that doesn't help, disconnect everything from your motherboard except power supply, CPU, CPU fan and video card. Look what happens.

Here's more info on boot troubles with your motherboard: http://www.intel.com/support/motherboards/desktop/sb/CS-010254.htm.

I noticed you're attempting to use an E6750. Which Intel motherboard are you using in your system?

Stan, thanks for the input, my computer guru is telling me to do the same things you suggested. So far the memory seems to check out okay, the motherboard beeps 3 times when the memory is removed, but stays quiet once it's re-installed.

I tried resetting the bios jumper, tried disconnecting the hard drive, and still no luck.... re-setting the processor is my next step. Then if that doesn't work, I'll try loosening up the motherboad from it's mounts.......



TQ- I'm using the Intel D975XBX2 motherboard.


My old computer is also acting up today. The Windows XP program wouldn't start up right, so I had to switch hard drives and am now coming to you from the back up drive that has Vista on it. My old computer is acting like a scorned woman.



errrrrrrrrrrrrrrr..................

That's likely your problem. The E6750 isn't supported by the D975XBX2.

Here is a list of the processors you can run with the D975XBX2:

By the way, my own home-built workstation is powered by the same motherboard. I'm running an E6600 with it.

Thanks for the information....I thought the motherboard would work with all Core 2 Duo processors....apparently not..... boy do I feel stupid.

The difference in the E6750 is that it's designed to run on 'boards supporting the 1333MHz FSB, such as Intel's new P35 or "Bearlake" class boards. All the CPU's that end in "50" are for this class of board. Also, no DDR2 memory officially supports the 1333MHz FSB speeds. You'd need DDR3 memory to work with Bearlake and the 1333FSB.   

Our D975XBX2 boards support 800MHZ and 1066MHz FSB speeds. 

BIf that doesn't help, try to boot your PC with only one memory stick in different slots. If that doesn't help, use another memory stick from another  PC.

The D975XBX2 uses a dual-channel memory configuration so attempting to boot with one memory stick won't work.

What you say seems to be correct, I just got back from Micro Center where I bought the processor, they wouldn't exchange it for the one I need,  but strongly suggested I swap out motherboards for a solution, because the e6750 is a great chip with the right motherboard, so I ended up buying a new ASUS motherboard, P5N32-SLI. Even though they stock the Intel board I have, they wouldn't recommend it, because of memory compatibility problems. So it looks like I'm stuck with a motherboard I don't need. Maybe my computer guru friend can use it in a new build with the right processor.

What a nightmare, but it's looking like I have a solution.

arrrrggggggggg computers !!!!!!!!!

Well...actually some overclockers have gotten the "50" series CPU's to work in the XBX2. They have to set their memory at 667Mhz (1:1 ratio) to achieve  this. But that assumes the board will boot with video and allow them to enter the BIOS, both of which you apparently can't do.

It may be that the problem is a conflict between what your memory's SPD setting is and how the BIOS reads it. SPD is the default memory speed that's read by the BIOS. Sometimes conflicts can occur with the SPD reading and the board will seem to power up but you can't get it to post. It's one of the reasons why I always use Mushkin RAM. Mushkin never gives me a problem.
If you can, try a different brand of RAM in your system and see if you can get to post and allow you to enter the BIOS.

The best solution is to always use a CPU that's rated as officially compatible with your board. I also would throw in use only Mushkin RAM, but that's only because out of all the various RAM manufacturers I've used over the years Mushkin is the only one that's never hiccuped. That's just a personal decision on my part, though.       

What you say seems to be correct, I just got back from Micro Center where I bought the processor, they wouldn't exchange it for the one I need,  but strongly suggested I swap out motherboards for a solution, because the e6750 is a great chip with the right motherboard, so I ended up buying a new ASUS motherboard, P5N32-SLI.

That's also not a good choice for that CPU, as it, too, only supports the 800 and 1066 FSB speeds. Not to mention it's an nForce-based chipset, not exactly my first choice for a workstation.
Yes, you can get the memory target speed to 667Mhz but the board's design is two years old. That's ancient. 

This, I think, would be a better choice if you have to go with ASUS. It's an Intel P35 chipset-based motherboard and has all the prerequisites.

Oh, and you can use your DDR2 memory in it. Shiny.

More bad news, the new ASUS motherboard is now installed but the computer won't stay running for more that about 5-10 seconds, still no signal to the monitor. This is getting expensive......and aggravating. I hate to take it Micro Center as they may charge me a king's ransom to get it working and returned.

When it rains it pours. I am going to be sick.

I settled on a Chaintech GeForce 8400 GS, 256 ddr2,  64 bit video card,

Just a thought: does the graphic card need additional power directly from the power supply? If that's the case, you'll find a power connector on the card, which should be connected to the power supply. Without that, you won't have video.

And how about your monitor? Is the cable connected correct to card and monitor? Does the monitor receive a signal when it is connected to another PC? Is the power on the monitor on (just asking, you never know...); where does the monitor gets its power from, by the way? From the PC or from the socket?

And to add one more possibility: are you sure the power supply is ok? I have had at least one new power supply which appeared to be DOA.
