My computer is more than 4 years old. It has Dual Core 2.8 GHz, 1 GB RAM, 250 GB HDD. After boot up, whenever I try to open any folder in my documents or to open start menu, it hangs for few minutes and doesn’t respond. The Task Manager shows a CPU usage of 80% and 240MB RAM usage. But I have seen that none of the processes takes more than 5 MB during boot up.
How to troubleshoot this since there are very few startup programs?
