Ok - I've had a look at your WCG settings/Device Profiles and also Results Status for the work units:
You are showing all of them still 'in progress' with none yet completed/errored/invalid.......and as you have been cruching them on these 2 PC's since 5th March that is not normal - assuming you are running them for at least a few hours each day then at least one should have completed by now.
The time for completion could be going up if you are shutting down Boinc and the work units are going back to the start each time, or to the last checkpoint and never given the time to move on to the next. How are you running BOINC on each PC, is it all day 24/7? or are you stopping BOINC from running every now and then or shutting the PC's down?
For each PC, ie. 'BuildPC' and 'ChrisPC' can you please list what Operating System is on each and how much time per day you have BOINC running, and also can you post a screeny of the BOINC 'Tasks' screen for each PC whilst units are running.
Thanks
