Cannot get new computer to work...
I'd really appreciate some help here, I am at the end of my rope after trying for almost 2 weeks to get a new computer working with Linux. The problem is that the machine runs Windows flawlessly, so I can't return it to the store, as apparently the hardware itself is fine.
What happens is that eventually 'random' errors start to crop up. The install might go ok, but when I download updates, I get errors complaining that several of the packages are corrupt and can't be installed. Also when I download large files from the internet, sometimes they arrive corrupt (incorrect MD5sum). I thought that there might be a networking problem, but it isn't just that: I also get faulty results in compiling (locally). For example, I might compile a project and and have it crash when I run it (in exactly the same way each time - as if the generated binaries are faulty), but then I do clean, compile it again, and it runs fine.
This basically makes it impossible to use the machine for anything serious (which I need - this is intended to be a development machine).
The machine is the following:
Core 2 Duo E8400
Gigabyte GA-EP35-DS3L motherboard
4GB RAM (OCZ)
Gigabyte NVidia 9600 GT video card
Western Digital 250GB hard drive
I have tried both Ubuntu (Hardy) and Fedora (9), same issues on both, so I don't think it's distro-specific. I tried 32-bit installations for simplicity, but also once I tried 64-bit. I've installed from scratch at least 6 times now, and the same sort of issues occur. The CDs I am installing from have been verified and they are fine.
All hardware tests I have tried turn out ok: I did cpuburn for a long time, memtest, prime95, I tried scanning for bad sectors repeatedly (e2fsck -c -c) and found none. It's the strangest thing.
Note that this is without the binary NVidia drivers, so that isn't the issue (however, when I install them, the card runs 3D fine).
Any ideas on how to figure this out are much appreciated!
