Hi, When I put my computer on a black screen comes up saying windows has no successfully done something .... ect I get things to do like. Start windows normal, safe mode, with network, with command prompt, start windows last working point ect ... Whenever I select one of them it restarts flashes a very quick blue screen of death and restarts to return to the screen so i'm stuck in a circle. I tried hitting R to repair to OS when I put the disc in and it was examining the HDD for about 4 minuites is that to long? I restarted it ... because I wasnt to sure if that is how long it takes and I was worried about loosing data. Sorry for the really bad explaination, any ideas?
