Hello, i have a little problem i was hoping someone here could help me with. Compaq 705US laptop computer 20gb hard drive 256 mb ram 1000Mhz AMD athlon 4 win xp home This is my father`s computer. He restarted it, and when it came back on, there was an error message. "operating system not found" after trying to start from a boot disk, and even trying to reinstall the operating system, i came to notice that the hard drive is not being recognised. I tried to open the case to see if maybe the hard drive cable had come loose (I`ve never worked on laptops before, only desktop computers) but after removing all of the visible screws on the bottom, the case would not open. I did not want to try to force it, so i decided to come here to ask people with more experience what i should do, and what you think the problem may be. I sure would appreciate any help.
