Thank u very much guys for your helpful tips! I appreciate all your inputs and how i wish i have posted my query much earlier.........
Unfortunately....
My system went down just yesterday....when i tried to restart...it went thru a network boot....then look for a boot disk (A)...and nothing more. :'(
When I tried to restart again and press DEL to enter the SETUP menu...my HDD did not appear ( i.e. Primary Master, Slave--not installed)....only the 2 cd drives are there...
Last resort, i brought my pc to the dealer to check the drive.....IDE cables....whatever...(sorry im not very technical abt hardware stuff).........still nothing!
The guy suspects that the hard disk is dead...what da!!!
i dont know what just happened! so i asked the guy to try to put a new HD just to check if it will work...
same thing happened...the system cant detect the NEW drive...
now he's thinking it might be the motherboard....honestly, i really dont care if it is indeed the MB...what i care about is my data on the drive!!!! im afraid i will lost everything i have on that drive...OMG not again!!!!
i dont know how you guys will react on this but just want u to know that im very thankful for your replies...
