CRC error System Halt
After changing the CPU fan (back to an old fan as the new fan started to sound to much) the computer does not boot. It says:
Where should I start looking for errors? Harddrive, RAM? Or could the fan switch itself cause this?
Also after trying to boot several times, it is now not displaying anything (not the text above either), so I guess I now have an even more serious problem? The screen is totally black, no sign of booting.
