I had an old amd Athlon 64 x 250 and bought and amd Athlon II x 4 640. But when I install the CPU and switch the computer on.
All the fans move very fast. There is no signal to the TV

I have 3fans, including the CPU fan.

3Sticks of ddr3 1600mhz ram and a Asus HD 6670.

Any help?

^ This person is most likely correct. Odds are, you're using an AM2 motherboard, and the new CPU you bought is AM3. An AM3 motherboard can use either of those CPU's, but not true the other direction. The good news is that even a very cheap AM3(+) board is likely to be a big upgrade from what your were seeing before.

EDIT: Saw your other post, so scratch what i said, that's a pretty new board. Try flashing to the latest bios with your old CPU before swapping in the new one.

Make sure you've got the CPU well seated, and remove the cmos battery for a couple minutes before trying to boot (this will reset the bios). If you have another AM3 board computer, try swapping your new cpu in to see if it's just your cpu...also re-seat the ram, that often turns out to be the issue, which throws people.

Your motherboard does support the CPU. Can you check which version is the bios? If under (0208) you will need to update it.

If it's the correct bios version, maybe check if the processor hasn't got any damaged pins and if every connector on the motherboard is properly attached.

Use just a single memory module and see if that works it out.

Reset the bios/Remove the motherboard's battery to reset it. Some configurations may not be applied and auto reconfigured to the new CPU.

Try the processor on another motherboard, see if it boots.

Last one is really call your motherboard's tech support or the place where you bought the processor.

Hope this helps.

Check for cable connections and check if the CPU isn't damaged on the pins

Test the system with just a single RAM Module. If still nothing, call your tech support/CPU vendor/Motherboard manufacturer.

A bent pin can be bent back into line and the CPU should work just fine, it could save you an RMA and some time, i bought an Phenom ii 1100T once for super cheap because it had a bunch of badly bent pins, i bent them back and it worked perfectly. Just saying.

And if he for some reason trying to fix the pin breaks it? There goes the RMA and the processor and his money. I never recommend anyone that isn't experienced, doing so. I'm not saying he couldn't try it, but better safe than sorry.

Yeah, i understand where your both coming from. But i wouldn't want to take that risk. But you guys have been excellent and helpful. Hopefully ill get another processor sent soon. Hopefully it will just work straight away.

I spoke to the person i bought it from, he refunded me the money back for it. Then i gave it ago and bent the pin back in to place and it worked fine after. Took me a while though.
