Custom Desktop with OS booting issue - TDR - National Repair Center
Customer was suffering from no boot on the PC. The windows circle would just keep spinning. Safe mode and resets do not work, and recovery is corrupt. seems like a major virus infection and the best way was to refresh the entire OS. Viruses are best removed by completely rebuilding a computer. We re installed windows 10 and advised customer to update his windows and get anti-virus for future use.
Preventative maintenance is the way to go so you are not forced to repair anything, just make sure you are protected.
