Try a program named memtest86 It runs at system startup and detects defective memory modules.
As you have minor corruption problems it appears to be a memory problem. Maybe a F8 in windows initialization have a memory test program too.

About the influence about dev team I agree too , but they keep saying that the corruption problem do not come from update or new script , another problem is that our new deployement system work with patch , before we did backup/restore for each major update , that was a little constraint but there was less errors , at least corruption problem were discover before going too big . I hope to find someday the cause of corruption with no doubt about it source , for now i am not experienced enough to do this , I keep working on my repair tool and after that maybe I will find out why .

Normally, it would not be OK for you to have 100 corruptions (assuming an average of 2 per week) when Alan hasn't experienced any corruption at all.
