hi My secondary PC with a TVI card is in a continuous reboot cycle and does not complete the login and display of the GUI. So far removed SSD boot drive and tested with fsck and smartctl - reboot cycle continues with disk removed and a Fedora Live disk in CD player removed TVI card - reboot cycle continues used a PSU tester all values report nominal - reboot cycle continues used Fedora Live disk to run memtest - 15 cycles over 12 hours completed without error and text display replaced graphics card - reboot cycle continues HDDs are new less than 2000 hours so HDD newish SSD tests OK DVD boots Fedora Live disk mb & ram & video runs in non gui mode PSU tests as OK graphics card replaced TVI card in or out makes no difference suggestions (new PSU would be next step) Steve
