Just recently Windows is taking about five minutes to open. It begins to start then the screen goes black for some minutes before Windows finally opens.
I haven't changed anything or added loads of photos etc.
My PC has Windows XP with Comodo Firewall and AVG anti-virus (Free version)
It's an 'specialist built' pc with a 495gb hard drive (c) and 435gb back-up. Does that help ?
I was told that Microsoft Essentials anti-virus was inadequate. I've been using AVG without any problems for six months and the problem started a week ago.
