I have just recently built my new system which is a e6300 2gb pc5300 ram 250gb sata and x1950 pro with a 775dual-vsta. Having got it all up and running i seem to be having some problems with stability. I get crc errors quite often and every time in do scandisk i get errors found. I have used memtest to check my memory and there are no errors with that. Could i have a faulty harddrive. Also when i download files they seem to be corrupt quite often.
