Hihi..... im new here and my notebook has encountered a very serious problem and i need everyone's advice here.... i've searched through the forums and i cant find similar problems....hope u guys can help me out....

this is my notebook's spec:
Twinhead
Pentium 4 Mobile 1.7GHz
192mb DDR Ram
30gb Fujitsu Harddisk

This notebook is around 5 years old, and since last few months, it has been restarting once my notebook gets very hot, so i ll put some solid objects below my notebook to let it cooler and the problem has reduced....

Until yesterday, when i boot my notebook, after the bios screen, the whole screen is black and no windows logo appear, i tried to press f8 and get into safe mode but its stil the same.... and i noticed some how when reading my hard disk time....its very slow....therefore i went to bios, set everything into optimum settings and tried to auto detect my harddisk again...... and yet it doesn't solve the problem.....

Without hope, i let my notebook load up normally and see what happens, and after a few minutes, it says that my hal.dll is missing or corrupted, then i was so excited as i thought that i can solved the problem by just replacing the corrupted hal.dll with a backup one.....but i was wrong....

I tried to use Windows 98 disc to load the dos prompt with cd rom support, and strangely, it load up very slow, and its even slower when i browse into the c:\windows folder, and when i browse into the system32 folder, it says unable to read, gived me options:abort,retry or fail??....sigh.....

I didnt give up, i even down and burnt the Knoppix and Bart's PE disc, and loaded them into my notebook, trying to browse into system32 folder , and the same problem appear, very slow and even hangs.....

I think this is my hard disk problem, therefore i downloaded the "hard disk diagnostic tool" from fujitsu web site, but this time, i cant even load the windows 98 prompt, so the dianostic tool is useless now.....

Can anyone help me here....?? im totaly desperate now....
