Hey there. I am experiencing random application in a newly re-installed Windows 7 setup. This install happened after I installed a new SSD (on which Windows is installed) a new 3TB HDD. The crashes and BSOD's happened before the re-install, but more frequently than they now. The BSOD messages I get seem to change from time to time. I have gotten: MEMORY_MANAGEMENT IRQL_NOT_LESS_OR_EQUAL I have attached the logs from the W7F Diagnostic tools, in this zip are also screenshots of all tabs from CPU-Z : View attachment W7F_14-04-2013 (1).zip In my device manager I can see 3 "unknown" devices which are all Universal Serial Bus (USB) Controller's. I have not been able to find out how to install the drivers for these. Hope you can help me gentlemen and ladies! Thanks in advance!
