My computer does not start up and hangs at splash screen of win XP. It started in safe mode, but can not find any reason as to why the normal mode is a problem. I've tried running Mcafee on startup, but does not work and also run Malwarebytes which came with one minor Trojan. This has been removed, but no changes in the problem. Tried restarting it countless times, but it would just be the same each time. Help me ???
