First, sorry as I'm not technical savvy. Need some help. My desktop is 1 year old and already having problems. The computer is taking a long time to start up (example; when I on the computer, the windows XP Professional takes a long time to set up). Also, even normal applications and surfing the web takes longer. I know that the slowness is not due solely to the internet connection. FYI, computer is custom built. Processor is Core 2 Dual 1.86GHz with 2 GB RAM. HDD should be 320 GB. Using Avast antivirus. What is wrong with it? How can I check and correct it? Thanks.
