I am buying i5 cpu is that my 160gb hard disk which is used with Pentium, is that these hard disk will be use( connected) with i5 cpu or not and how ?
these hard is not a sata drive.
You'll have to find a motherboard that still supports PATA (Parallel ATA) hard drives which may not be possible since almost everyone has moved to SATA (Serial ATA) since the i5 came out.
