Dear Mike Barnes
thank you so much for your reply so quickly,i appreciated so much.
i spoke to computer shop owner about if i can upgrade to ssd drive,i told him that i don't have AHCI funtion.
he had a look for the BIOS and told me that i have ACPI,and APIC,and i can upgrade to ssd drive(with no problem).
i will go to BIOS and update the SATA to the highest settings(I,II,or III)
no my pc doesn't come with windows7(64 bit),i bought windows7(64bit) and reinstall windows (from scratch) by myself.
my pc is about 5 years old,sorry i don't know my motherboard chipset or model,i know only it is (packard bell,ipower,model 8088)
-If i have SATAIII in the BIOS,can i activate SATA III,and be able to install SSD drive without any problem?
yes i am going to buy samsung ssd 256pro,and re-install windows7 from scratch
i hope to hear from you very soon.
my kindest regards
