Installed new CPU and now my PC doesn't boot up

[Somethingformal]

Hi, I recently installed a new CPU (I5 3570k) and after I installed it my PC won't boot properly. It turns on, my mobo (ASUS P86P7 Pro) LED's turn on and my fans turn on but nothing displays on my screen, and after a few seconds on being turned on, it turns off and turns itself back on again. I tried inserting my old CPU (I5 2500k) to see if my new CPU was the problem but the same thing is happening. I have tried removing each stick of RAM and trying it again with 1 at a time to see if the RAM was the problem but it solves nothing. I was also thinking it was maybe the GPU displaying nothing ( AMD Radeon 6950 twin frozr II) but my Mobo has no on board graphics so i can't really check that. I saw a thread from a few months ago with a similar problem and the solution was to update the Mobo, I wanted to try to that but I can't access my BIOS because it doesn't display anything with either CPU. I'm all out of ideas and could really use some advice if anyone has any to offer.

Thanks guys

bent pins?? its looks easy to do with intel form what I see.

Sounds like the motherboard has an issue. Why did you even waste the money on a 3570k when you had a 2500k to begin with? You could try a CMOS reset.

Have you tried booting up and using your processor's HD graphics? Also, you might try clearing your CMOS via a button either on the board itself, or on the back panel.

yep probably the cmos

You were supposed to update the BIOS first with the 2500k ( if possible). I am not 100 percent that the p67 chip set has support for Ivy I think it is only z68 and above.

I was wrong it does support the Ivy Bridge sorry.

I would try to get a magnifying glass and make sure you did not bend the pins. If the CMOS reset does work with the 2500k but not with 3570k you will need to update the BIOS

I am not 100 percent but I am 99 percent that the p67 chip set does not have support for Ivy I think it is only z68 and above. I looked on the asus website and did not see any Bios updates for that motherboard. Is your board the p8p67?

Your right it is the p8p67, it was already updated I just wasn't sure if I should of updated it again

I got given it so I thought I might as well install it since I have no interest in overclocking with the 2500k, and il try the CMOS reset now

ya I was just also looking at that bios update at asus and the chip is listed but now he says that the old chip is not working now so I thought he needed to look at the scocket to see if it got damaged? if he put his old chip back in it should of started up as normal if there were no other changes and it was working fine with it to start[??]

I have had some weird things happen that took a CMOS reset to resolve. It is an easy check to try before tearing the system down again. To be honest, OP, you would have been better off selling the 3570k and getting a decent aftermarket cooler, changing the multiplier to 40 for 4.0ghz and getting yourself a nice SSD.

Yeah I agree

Yeah i probably should have after the trouble its given me, and im not incredibly sure how to go about doing a CMOS

It is usually just a jumper on the motherboard. It will be in your motherboard manual. If you don't have it on hand, Asus should have a link to it online. Another easy way, is to remove the battery for a few minutes. Make sure your system is unplugged when you do either way, to reset.

I have followed the manual, and also done the battery way but still nothing displays
