I've got a problem with my computer since a couple of days. I ran a fsck which gave a couple of problems with my filesystem (ext4). A day later my OS was no longer booting. Therefore I tried to reinstall Kubuntu 22.10 from USB Stick but it fails always at around 55% of the installation. It says that the checksum of e.g. libxul.so is failing. I looked with help of the life system into the device and saw that the filesystem was corrupt once I reached a fill level of the disk of about 6-8GB. Before everything was fine. This problem comes up even if I switch to a different device (I've used NVME1.4 WD Black 2TB, NVME1.2 Corsair MP600 1TB and an old HDD Samsung 1TB on SATA). Always the same problem. I changed also the USB sticks, always the same result. I tried even a BIOS update. My HW is a 3950x with an ASUS E-Gaming x570 and a GTX1660 with 64GB RAM.

Any suggestions if this is more a SW or a HW related problem?

It was a strange error pattern for me to encounter. When installing Kubuntu, a checksum error was displayed with several different nvme's or hdd's, so I assumed that the motherboard had a problem. I balked a bit at the rebuild, talked to a few more colleagues, and one said that this could also be a RAM problem. Since this was the easiest thing to do, I bought a new set of RAM bars, put them in and lo and behold, the error was gone. My explanation is that the data sent to the mass storage was altered by the defective RAM, so then the checksum error occurred.
