Recently i have been having lots of crc errors whilst unzipping files. My initial thought was that one of my hard drives was on its way out. I had checked them all using the manufacturers diagnotic ultility (Seatools) with all testing features and each one, on all drives, returned without error.
I thought my suspicions were confirmed when i turned my drive on for the BIOS not to recognise one of my SATA's (a Barracuda 7200.11). After a bit of research i found out that this was prob not the cause of my crc errors as the SD15 version of the firmware supplied with my drive had a bug and causes the drive to go into a hibernated state, a separate issue i'm dealing with.
After removing this particular hard drive along with Vista out of my system i installed win XP onto another drive temporarily. I am having the same problems with the CRC errors on my other drives which seem to be operating normally. The kind of files i'm talking about are fairly large usually demos or trailers etc in .rar format.
As i understand it CRC errors can also come from faulty RAM. I have recently RMA'd some faulty RAM back to OCZ and the stuff in my system currently is the brand new RAM i got sent back from my RMA. I know this can be causing the CRC errors and occasional random restarts regardless of how new it is so i have checked both sticks individually using memtest86. I only had time to let them do 1 pass each but both came through error free.
If any of you out there have any suggestions for what else i can do to figure out what is wrong i would very much appreciate it. Could it be a lack of wattage on the psu causing the restarts and if this was a separate problem where are these crc errors coming from? Could it be the Processor? I'm stuck, please help
Sorry for the long winded explanation but i thought i'd try to get as much detail out there as possible
