I get the double fault halt (blue screen, error 7F, code1 8, code2 80042000, code3 0, code4 0) when I am extracting something from 7-zip archives. The halt never occurs except for extracting from 7zip archives. The halt occurs on every 7-zip archive, both on regular archives and on self-extracting archives. The halt always occurs in the same position of extraction process, as per archive; the position is different for different archives, but always same for a particular archive. I heard the double fault halt can occur because of damaged RAM, wrong hardware connections or kernel drivers errors. I checked the RAM thoroughly, and the RAM seems to be ok. I tried changing RAM, - the halt still occurs. I reassembled the PC, - the halt still occurs. So I guess it is a kernel driver error, isn't it? I am attaching the minidump file. Please help me. Thanks.
