No idea what to do
 

Hello, I want to know how do I find out information about my computer's system like processor, the hard drive, ram that sorta thing...

Try the following:

First command will give you info about your CPU (CPU should be upper case)

dmesg | grep CPU


Second command gives info about RAM:

demsg | grep mem


Regards,
Greenie

cat /proc/cpuinfo
cat /proc/meminfo
df -H

lspci for cards, etc.

hdparm -i /dev/hda (for primary hard drive, /dev/hdb for secondary/slave, etc.)
