This sounds more and more like hardware troubles.=20 A few things to check (in order of decreasing likelyness IMHO): - Cables to the harddisks: Make sure they are properly connected. A machine= of mine suddenly started getting disk read errors after I put in another graphics card. It turned out that the SATA connector to that drive had co= me partially loose. - Powersupply: check the voltages (preferably under load) with a monitoring app like mbmon. If that's not possible, check in the BIOS. A failing powersupply can give weird unreproducable errors. If you have ever heard a popping noise from the machine it could be a short in the powersupply cau= sed by dust. I've seen that fry motherboards. - PCI cards: check that they are seated properly. Although in this case I'd say this seems the least likely.
