I don't know much about systems.
I can feel it very slow.
It might be the hard disk. I have bought 1TB hard disk and it is sata.
I have windows 7's default virus scanner and it is upto date.
I don't know how to troubleshoot this.
Please ask me questions, so i can post more details.
When the system loads, The desktop icons become like an "unknown" icons and it takes more seconds to become the normal icons.
If i open firefox, it is also taking longer time to load. I have to wait for every small events.
If i shutdown the computer, it takes longer time.
System has only one OS.
Windows 7 64 bit.
