Kernel Panic Bootloop, Help Appreciated

[23EBradley]

Hello, I have a iMac 20, from early 2008 and i have recently had a disc stuck in the internal Superdrive and i had gone to open the mac to remove the disc stuck in the drive, I had put it back together and powered it back on to be greeted by a Kernel Panic, the computer wont boot to the boot menu where I have tried booting to a USB with Windows 10 as its capable to do so, No keyboard combos work, I had tried removing the hard disk which i had managed to boot to the boot menu finding my USB and selecting, it then freezes.



Help would be Very Much Appreciated and No i do not have the Money to get myself a new mac and it runs perfectly fine (before the kp)



got the kernel logs from a photo i had used Google Lens to extract the text below followed by the original picture.

Hello and welcome.

Sounds like maybe an internal connection isn't seated properly, or there may have been some static or other physical damage done when it was opened/reassembled.

The log shows a lot with regards to the CPU, so it could be several things - CPU/logic board/RAM/etc.

Without being able to see it in person, it will be difficult to narrow down further. May be time for a replacement unfortunately.
