It takes 5 minutes from switching on my destop computer untill the log in screen appears, I get all the load up writing at the beginning and the windows logo but then a black sereen for up to 6 minutes, I have checked all my start up programs I have only 41 , I have run a virus and malware scan and also defragged, I am running Windows 7 64 bit. everything runs fine once it has finally loaded. The computer is around 18 months old and under warranty BUT!! If I take it in I know they will just flatten it and start again and I really could do that myself if needed to but I do not want to osse everything. PLEASE can you help me? I have checked and done most things I have read about with no luck. I update evrything when I should etc . Thank you Mrs Yvonne Woolley
