PC doesn't start after upgrade

JayTheSheep · Nov 24, 2016

Hi, I bought a used i7 4770 to replace my current i5 4460. My mainboard is a AsRock B85M Pro3. So I replaced the CPU, applied thermalpaste and all, and when I start my PC with the i7 installed, the pc turns on, turns off after like 1 second and then turns back on again and I get no signal and it seems that USB ports arent working aswell. Installing my old CPU works and the PC starts as usual. I tried clearing CMOS and updating my BIOS, but still nothing. I also tried switching RAM slots. I'm really out of ideas now. Is it broken?

Try to look bottom side of CPU to see if it is damaged.
If you can take a picture of CPU bottom side and post here so we can tell for sure if it is damaged or not.

Not sure if this is enough, will take another picture later if needed. I actually broke the CPU pins on my motherboard so I got to buy a new one or might try to bend them. God damnit.

Try to fix them 1st, if they didnt fall of you can still fix them.CPU looks fine to me.

Alright, thanks! Hopefully I can fix them. Another question: Will the pc even boot when the CPU is broken? Because as I said, it does boot, only no signal/no usb

I dont think so, i cant give you proper answer here, never had a PC with a dead or broken CPU to work with. You will need to wait for someone more knowledgeable than me.

Okay so my new mainboard arrived today. I installed the i7 and guess what, same shit. No signal, no usb and this time the mainboard has lights aswell (h81 gamer) and the lights dont light up when the i7 is installed, only the Standby light. Pretty weird, huh? My i5 still works and the lights light up. Any ideas?

Try to update BIOS on new mobo and after that do BIOS settings reset to Default/Optimized settings.

It came with the newest version

Can you post another picture with more focus on CPU, i think it has some damage in upper left corner.

I made a video with my flashlight on, turns out it looks like it has a weird spot on it.

It could be some water damage or from thermal paste.If you cant return it try to use dry tissue that is soft and clean that.
