New processor doesn't work

[Dragon Tamer]

I'm running very old hardware. I just received an Intel Core 2 Duo E6700 which is supposed to be supported by the mobo.

When I put the processor in, the system fan and the CPU fan are not running, system makes a beep and refuses to boot.

Anyone know what's going on, did I just get a bad processor?

Mobo is here.

Have you put back the old CPU to check the MB?

[Dragon Tamer]

Yes, as soon as I put the old CPU back in she starts right away with no issues.

You may want to see if there's an update for Mobo BIOS.

I'm sure you have been over this already, but here goes anyway.

Did you make sure you aligned the CPU properly with the socket? Did you use too much thermal paste? Is the CPU heatsink tightened down properly? Make sure all power connections are aligned properly, and inserted fully. Did you forget one? Either the 6p, or 8p CPU power plug (one or the other) can be inserted inverted, so you have to check that the locking side lines up with the locking tab. Also, the 24p plug has a 4p insert that might back off slightly (I've seen this on some boards). Check your MB manual to be sure you are using the actual CPU fan pins. I have at least two boards (meaning different manufacturers) that have a second four pin header that is not the CPU header. Did you insert RAM into the proper sockets? Are the RAM modules fully inserted?

If you have checked everything, then reset the BIOS to default and reboot again.

If none of this helps find the solution then try your old CPU again.

Everything checked out on the motherboard. I did find a single pin in the socket that was bent out of place so I put it back. It still refused to boot with the new CPU. I wasn't able to update the BIOS either, not sure why. I kept getting an error, after Googling I did what was suggested and it still wouldn't work. I'm assuming that it's because the only BIOS update was centered around windows XP which no longer exists on this rig.

I've got parts picked out for better upgrade (new ram, CPU and MOBO) that should be a vast improvement over what I've got now. I'll probably try to build some sort of browsing/HTPC around this processor that I got. It would be nice if I could somehow check and see if it's even working first...

Now looking at this I found there are two E6700's . A Intel Core 2 Duo E6700 Conroe (2.66ghz)  and an Intel Pentium E6700 Wolfdale (3.2 ghz) .  Any chance you got the later by mistake?  The wolfdale is not compatible with a Q965 chip set from what I've read . 

It might be a shot in the dark but i would take a look just in case .

They're both Socket 775.

Are you getting a beep code, and what is it?

[Dragon Tamer]

The processor is indeed a Core 2 Duo E6700.

I dropped it in and left the power on for two hours yesterday and nothing happened. The fans never came on, the fans on the graphics card were running and I could hear the hard drive reading something right after powering up, but nothing ever happened. The processor never even got warm. I was getting beep codes earlier but it was a single beep when the processor was first installed and it hasn't done it since.

They're both Socket 775.

There's exceptions, tried to do beef up another HP with a known good processor, didn't work. "Intel Core 2 Duo E6x00 with Dual Core technology (Conroe core)"  is what I understand the best possible processor for that mobo, the rest being Presler, Smithfield, Cedar Mill and Prescott, as the link says.

Not an expert but if the CPU fan doesn't come on that's a problem that might not indicate a problem with the CPU so much as the mobo or you. If the mobo doesn't see RPMs from the CPU cooling fan that should generate a boot error. It'll try to save you from frying your CPU because you forgot to plug in the fan. My Asus board has an led that shows the error code but most just beep in different sequences for different errors. See the mobo manual for the codes. Some boards might have to have the little speaker that came with it plugged in to hear the beeps. Some have the speaker built in.

Make sure you have the CPU cooling fan plugged into the right socket. Of course, if that socket isn't giving voltage to the fan that's a mobo  problem. It's a good fan right? Hadda ask.

Sounds like you found the answer; bad CPU.

[Denniss]

Either the CPU is bad or the Bios is too old, many Intel-based boards do not boot with unsupported CPUs.

[Dragon Tamer]

I've concluded that it's the BIOS doesn't support the CPU. I can't install an updated version of the BIOS for reasons that I don't fully understand. I emailed HP and they never got back to me (assuming it's because they thought it was a joke).
