Hmmm..Bad CPU?

I just bought a new cpu, mobo, ram, and vid card.

It's a gigbyte mobo....intel core 2 duo e6750 cpu, 2 ocz sticks of ram, and an nvidia geforce 7200 gs..

I got everything connected...but no video out. When I plug in my usb keyboard...and hit caps lock....no nice green led light..

Please help as I have spent over $500 for this new setup and its not even working.

Thanks c9

With the information given, it could be the motherboard, graphics card, RAM, or CPU.  Do you get any POST beeps or anything?

I find the best way is to start with one thing at a time.

1. Take out the cpu, ram and anything else plugged into the motherboard (except the power)

2. Turn on the computer.  It should beep at you.  This means your motherboard is POSTing and is working properly.

3. Turn the computer off (you will have to probably hold the power button for 8 seconds)

4. Plug in the video card and connect a monitor.  You should be able to see the post happen (or it will just beep at you because there is no memory or ram)

5. Turn the computer off.

6. Plug in the CPU.  Turn on the computer.  You will either see it POST or beep at you beacuse there is no memory

7.  Plug in the memory. Turn on the computer.  This time you should see it successfully post.

A couple of things to check.

1. Verify the memory and CPU are supported by your motherboard.

2. Verify that the motherboard or video card does not have any extra power requirements.  You should be able to find all this information in the product guides provided from the manufacturer.

 

1. connect monitor to on-board (built-in) video
2. go to BIOS
3. disable on-board video
4. connect monitor to normal video card


PS: bloody hell... How about to name MB model?

PPS:
- Doctor, I fill bad, I fill pain somewhere...
- Ok, I will give you some medicine...

Ok, thank you very much!

BTW, there is no onboard video

And the mobo is a Gigabyte DS3


I will try what you all have said I should do and I will post back.

Are you sure? MB from your link displays MB with on-board video...

Actually no if you look at the specifications for the DS3 the system list stated ONBOARD VIDEO CHIPSET NONE.....

So he is corect there is no onboard video on the DS3

Did you plug in the P4 connector?

#4 is a bit wierd. Yes, you might hear a beep sounds (assuming you can turn on the computer without a CPU) but there wont be any video output or input functionality. Not that I'm aware of anyway.

If that's the 4 pin power connecter then yes.

I think this board may be bad since when I plugged the cpu fan into the board...it spins about 1/16 of the way then stops. It basically "jumps" when I turn the pc on. I plugged the fan into a cord coming from my fan controller and it spins.

I would reseat the motherboard, it could well be shorting out.

I think its extremely rare to get dodgy processors as they are tested at creation but generically to check their transistors are working, then most cpus given their clock speed by what they can actually achieve..

The high end processors are really just the best of the crop..

Not neccessarily.  Are you hearing any post beeps at all?

If not, then take the whole thing out of the case, put it on a piece of cardboard and see if it will boot from there (what steveo_ said, but more detailed).  I've seen the 'fan jump' issue before with a bad CPU as well as with a dodgy spacer on the back of the mobo.  Also, make sure you've got a fan for the CPU and you've actually hooked it up and have decent thermal on it.  It sounds obvious, but I've seen people get overeager   Usually, the chip just shuts down, but sometimes, it's just gone.

Just for future reference, you can usually set your whole machine up outside of the case to test for this stuff before you scrape your knuckles and such

I just built a system that did a similar thing (the fan kept "twitching"). I think the CPU fan speed control feature in the BIOS just wasn't sending enough signal to the fan at low temperature (it's one of those big Zalman things and had two 120mm case fans running right next to it). After disabling that feature in BIOS, the CPU fan spun at full speed. After re-enabling it with the CPU warmed up it spun at a nice quiet rate.

Not that it helps if you can't see the BIOS screens :/

Is the power supply good enough to handle all the new equiptment?
