[SOLVED] Are my motherboards fried?

[francis.catolos]

Hey, so I have an i5 3570k's and an i7 3770k. I have 3 LGA1155 boards. While installing a liquid cooler on the 3770k I accidentally slipped and bent the corner of the cpu. I thought i could simply bend it back in place and it still place in into the motherboard. Unfortunately, when turning the power on, it powered on for a split second and then shut itself off. I took this to mean that the CPU was dead.

I decided to troubleshoot however by swapping the 3770k out for the 3570k to see if it was in fact the motherboard instead of the CPU and it resulted in a continuous boot loop or 2 second intervals.

I assumed then it was the motherboard because i litterally had just taken the first i5 3570k from a working system. I then decided to test the 3770k in the 'working' system because i thought the other motherboard was faulty but it had the same result of powering on for a split second before shutting itself off. Unfortunately I placed the i5 3570k back into that same 'working' rig afterwards and got stuck with the same 2 second boot loop.

I frantically took out the i5 3570k and placed it into the 3rd 1155 board and it worked perfectly fine.

I take this to mean that the broken 3770k unfortunately fried the first 2 boards. I tried resetting the cmos, and tried other power supplies but nothing seems to fix the boards with the 'working' i5 3570k.

Are my boards just dead? or Is there anyway that i can fix these =/

Thanks for the help!

They could be fried or they could turn themselves off to prevent damage and could remain on such state until there isn't any power on the capacitors.
With the power cable disconnected, disconnect any power connector cable (24pin ATX, 4-pin 12V, etc) from the motherboard press and hold the power button for 20 seconds then remove the CMOS battery and leave the motherboard for a day.
Try installing the good CPU and see if it works...if it doesn't then it could be dead.

I agreed with you, the broken i7 did kill two of your MB. When you bent the corner of the cpu, that may break something else inside the pcb, when you put it into the 2nd MB, the PC does not boot, that means the cpu has problem, then it damaged your two MB. So forget about these two MB and the i7. Sorry.

I tried your suggestion, but unfortunately no luck =[ I've come to terms that they're both dead now. I'm just really curious as to how exactly it busted up my motherboards. But thank you for the help! It was appreciated!

Yeah, that seems to be the case. Its unfortunate but mistakes happen =[

Do a google search on bent cpu socket pins and see if you can find any. The bent cpu might bend pins as you close the retention clip. Because of that, the 3570k doesnt work in the socket you put the 3770k in.

So, see if the two nonfunctional boards have bent pins and try to straighten them.

This was actually the first thing that i checked for, but none of the pins seems bent or out of line. I don't know if it's a thing, but im convinced that the 3770k somehow shorted some of the pins or something in the socket which makes reading the 3570k's impossibe.

Thank you for your response though!
