. Your two DIMMS 333 dims - although this board has 3 slots, only two at a time can accept DDR 333 DIMMs. I think you've most likely sorted that one, but just wanted to rule it out. You can check CPU/memory integrity with a program like Prime95.
. You only encounter problems when attempting to manipulate RAR files, right?
. RAR files can also be manipulated with other programs, such as Winzip or WinACE; see if you can install one of these and do the same - uncompress those files with them and see if you get the same errors. This will rule out whether or not there is a bug somewhere along the line with your WinRAR installation. Always use the latest versions of any compression software.
. Run a System file check to check your OS integrity as well as scandisk to check the status of your hard drive.
. Also, have you virus-checked your entire system?
There shouldn't be an issue with these boards and 2600+ Barton cores since the board can run FSB and memory at 400MHz.
