Don't know what cause it at all just want it fix please. Stuck on this problem for weeks. Starts normal then goes to bluescreen then it restarts and goes to repair screen. Attempts repair but fail then it restart and loops back again to bluescreen. Safe mode works but can't plug in flash drive to save documents and data. Only wired keyboard works. And safe mode with network stopped providing network and couldn't figure out solution to bluescreen. Please help. Thank you in advance.
