I'm no P.C expert by any stretch of the imagination but I hope my experience might help some one. Earlier this morning I could only boot into safe mode with networking,my normal mode had gone. I was fearing my new graphics card had bit the dust. I did the usual checking the forums to see if any one had any thing like my problem,there were similar problems but only a few reported back with the results of it being due to graphic cards. For me the msconfig didn't do anything for me. The system restore suggestion did work for me. The problem was being caused by the Asus GPU Tweak tool once it was gone every thing returned to normal.
I would like to say a big thank you to the people on the forum for indirectly helping me solve a problem.
