HI SQUAD, I struggle with this kind of problem: When computer idle, Copernic Desktop Search indexes the contents of the hard drives and after let's say 10 minutes of indexing, XP crashes and results in BSOD that reads as follows, except of usual knick-knack: PAGE_FAULT_IN_NONPAGED_AREA *** STOP: 0x00000050 (0x80D58318, 0x00000000, 0x804E8C7B, 0x00000000) - when I disable Desktop Search Service from TaskManager, PC never crashes - I used version 2.3 of Copernic, then uninstalled and PC never crashed - later I installed version 3.0 of Copernic, it ran perfectly for about 5 days, then again started to crash when indexing Many thanks for your help in advance, please don't persuade me to get rid of Copernic, I want to keep it and solve the problem.. dolfort

Download and run memtest86 from a boot floppy or CD. No errors are acceptable. Graphic card can also cause that error.

Run Disk Cleanup / Disk Defragmenter / chkdsk Start>All Programs>Accessories>Systems Tools (For the first 2 in that order) Start>run>cmd chkdsk /f restart your PC Test your indexing again. If it doesn't work, run the Manf. Diagnostic software on the hard drive to ensure it is not going bad- Also Memtest86 (mentioned above) is good for testing RAM Thanks for any input.

Disk defragmented chkdsk passed Memtest86 passed twice with no errors Still no help.- dolfort
