PC won't boot after new cpu cooler

[GiantSlay007]

Hi everyone

 

After replacing my old corsair h55 AIO watercooler with a be quiet pure rock slim cpu cooler, my computer won't boot.

 

When turning it on, it turns itself off after ten seconds and turns back on and then stays on. No signal to the monitor and no power to usb peripherals. There is a red DRAM led lit.

 

Things I already tried:

- switched all my ram sticks, also tried putting in only one stick.

- removing the new cooler and booting without it.

- Put old cooler back

- Check for leaked rubbing alcohol (from removing the old thermal compound)

- Removed everything, only the cpu power, motherboard power and on/off switch is plugged in right now. (also tried connecting the cpu fan to the header so the mobo would think the cpu fan is connected..)

- Checked the cpu socket pins (I think they look just fine? I attached a picture. It's socket 1155 btw.)

...but nothing worked

 

I did have to put a lot of force on the cooler to put in the fourth pressure pin. It felt like there was a lot of pressure on the cpu from the cooler but assumed this was normal. (the cooler plugs in like an intel stock cooler)

Did I really just break my CPU or CPU socket by replacing the cpu cooler? If so, how can I not make the same mistake again in a new build? pretty f-ing weird.

 

If you have any ideas, please let me know!

 

Thanks in advance

 

Specs:

i7 3770 (socket 1155)

4x4gb corsair vengeance 1600mhz ddr3

Asus P8Z77-M

GTX 970 (disconnected right now)

Corsair CS650M psu

You mention that the 970 is disconnected. The UEFI might be defaulting to PCIE for video out. Try doing a CMOS reset or plug the GPU back in and see what happens.

maybe check to ensure you didn't knock out a RAM stick.

Thanks for your input. I only disconnected the gtx 970 after the problem occurred, just to rule out that the gpu wasn't the problem.

Thanks for your input, I did, reseated every single one of them, they're fine.

check 24pin cable mb, when i reassembled my old pc it wouldnt boot, i thought it was gpu that was failing out of socket, but 24pin power was the problem

Thanks for your answer! I reinstalled the 24-pin mobo connector, also checked the 8-pin cpu cable. Still the same problem

There is a picture of the socket attached to the post

Wait.. those are the pins in the socket right?  anyway this is the back of my cpu

Did you use an anti-static wristband or at least touch metal before your PC, I'm just asking since I bricked my first built PC with static discharge.

it doesnt seem to be broken from i can see, as well as mobo socket. it seems you dont have any other cpu/mobo to check it? check your mobo on case of some electrical discharges as upper guy mentioned, any burnouts on radiators, power chains etc

No I didn't. O ooo 

[Kelums]

also if you were putting cooler in your case with mobo tightened with screws, you couldve just tide it up

[G0dSpeed]

Yeah I was 15 when I bricked it.....a good first lesson..doesn't mean you did the same thing but I had the same problem where it would power on but I shorted the circuts around the CPU.

Sadly I don't have any other socket 1155 motherboard or cpu laying around. I did just check it pretty thoroughly for burnt places or something like that but could not find anything.

well my translator said tide = break so i used this word. this is what i mean, break it apart into two, a small crack can make your pc wont boot

ooooh like that haha. I just took out the motherboard and put it on a plastic plate, only the psu connected. Still same problem... I can't believe I just broke the first pc I built 7 years ago

did you try resetting the BIOS?
