My computer has been going too slow since I remember, I tried several tips I found on Internet but nothing worked. After spending some time searching about the problem I found that it might be my hard drive so I tried to optimize it with hdparm but it doesn't seem to work because I get some errors whil eithere trying to activate DMA. After running hdparm -tT on my hard drive this is what I get:

Timing cached reads:     2 MB in  2.34 seconds = 874.15 kB/sec
Timing buffered disk reads:   2 MB in  4.15 seconds = 493.51 kB/sec

That's really poor performance compated to my external HD:

Timing cached reads:   1996 MB in  2.00 seconds = 998.20 MB/sec
Timing buffered disk reads: 102 MB in  3.02 seconds =  33.83 MB/sec

Is not it?

If someone can please help me to get this computer to run a bit more decent I'd appreciate it. Here's some info about the hard drive:

System specifications? Does your BIOS have an entry of IDE/ACHI for the hard drive? If it does, what is it set to? –  Mitch Jun 11 '13 at 6:38
