Burnt/broken processor? (Photo)

Good evening, Hello, I'll get straight to the point: I have a problem with my PC (I'll explain the issue right after) and after checking my processor, I would like to know if these marks could indicate that it's dead or not:
When I start my computer, everything runs normally but my screen displays "no cable connected." I changed the DVI cable, the motherboard, the power supply, the CMOS battery, checked the RAM sticks, obviously tested it on another screen, removed my GPU and connected the screen to my motherboard but still the same problem. However, this morning I noticed these marks.

This accident happened due to a small fall on its side (given the size of the tower, it's a small fall and on the right side) and then my screen froze, so I had to restart the PC by holding the power button (since I had no control over the screen) for a few seconds, and then this happened.

There are 3 black marks in total on the processor (initially, the 2 other horizontal marks are not very visible due to the flash, and previously these marks were hidden by thermal paste, but while cleaning everything I noticed them) so the one in the middle and 2 others towards the bottom. The heatsink also shows these 3 marks.

Thank you in advance for your help!

    Hello,

    The part where these black spots are located is called the IHS, which can also be referred to as the cap, and it is specifically meant to protect the die (the core of the processor) underneath. However, these dies are very fragile (like glass); they are generally made of silicon, so if dropped, it's possible that there was damage (but I think the PC wouldn’t start if that were the case, as it would automatically shut down for safety).

    Have you checked if the pins on the back of the processor are not damaged? (if they are, unfortunately, no repair will be possible)

    As for the black spots, in my opinion, it’s just a result of the thermal paste overheating (which may have "shifted" after the drop).

      Thank you for the quick response!
      If it's not the processor, nor the power supply, the graphics card, the motherboard, the screen, the RAM, the cables, or the hard drives, then what else could be causing this problem?

      I think the problem lies with the CPU. Here’s what I recommend you do.

      Remove the CPU from the motherboard and check if the pins on the back are damaged. If you had a heavy heatsink, it’s possible that with the weight, during the fall, it bent one of those pins.

      If you have another processor with the same socket on hand, try testing it on your motherboard.

      And if there truly aren’t any issues in these two cases, I suggest you check if you’re on the correct input on your screen (even though I think you’ve checked this first, but we can all make small mistakes).

        Thank you again for the response, I will check that and try to contact a colleague to test it with another processor of the same socket, obviously. (And for the screen input, everything is well set, no worries about that)

        I’ll keep you updated on the improvements.

      Re! Testing with another processor fixed the problem, so I'm going to order a new one. Thanks to you =)

      No worries and sorry for your CPU, but if the motherboard is fine, I think that’s still a win. At the same time, you can take advantage of it because it seems to me that there are promotions on rueducommerce right now.

      Good reassembly.
