My pc has this config.
Intel Core Quad CPU
2.39 GHz, 3.25GB of Ram
1 TB of hard disk (500 X2)
When I bought the PC I had only one 500 Gb hard disk and every thing was working fine.
but later I added one more 500 Gb hard-disk into the system.
Since then my system really does not work well.
In terms of speeds and performance.
earlier I had installed 2 windows 7 on two partitions(same hard disk).
But it really work so slow that I need to revert back to XP.
but even XP is running slow.
One thing I have noticed that my hard disk (on which my OS are installed) has only 8 MB of unallocated space.
but during installing windows 7 I deleted all the partitions and try to created it from windows 7 and it created a 100 MB( I guess) automatically and showing (for system use).
I am not sure how much unallocated space I need for File system.
Any one could suggests me how can I inprove the performance of my system
