Recommended configuration of Photoshop
P4 2. More than 66 processors
Memory above 1G (preferably 2G)
More than 80 hard disks, the bigger the better, and the system disk should be divided into 10G or more.
The requirements for graphics cards are also very high, but yours is integrated and naturally slow ~
The light on the hard disk indicates that you are working because your hardware can't keep up with the software. The light will always be on when the machine is running.
You'd better have a better computer if you want to do graphic design.
Recommend a configuration for you:
P4 3.66 degrees Celsius
2G memory
128-bit 128 MB graphics card
The motherboard supports dual channels.
This configuration can only be felt by PS!
