I have not been tried to install the hard drive to other pc that has sata slot. I had tried to reinstall os but it won't continue when I reached in selecting the c drive for formatting (shoes unknown drive).
Yes. There is a light and beep when I turned it on.
It is a desktop with a 1 stick 256MB of RAM, no video card, for the psu will send info later. Tried to unplug the RAM and turned on the pc but i had not heard any beep.
Before it was happened, there are instances that my pc restart itself. And there is that when i turned on, it showed combination of color or gray that forced me to turned it off and turned it on again.
Sorry for my late reply. Im at office right now and i was came from my day-off.
I had appreciated your help guys.
