I would reckon it being the Motherboard or the Hard disk.
Look at the hdd activity indicator. after switching it on, does
it like up? what is the colour of the indicator.
The Hdd's clicking sound makes it sound like the reader is stuck
or it has problems reading the data on the hard drive. However,
what puzzles me is that, if it has problems reading, Bios can still
be seen. - that means either the monitor/motherboard has
problems.
It could be a combination of problems, which we will find out in
due time.
The Dvd drive seems to be busy as, the computer is following the
boot up procedure.
every computer has it in it's bios, it would be in accordance to
which will boot up first.
If the hdd (in the first slot) fails, it will go to the nxt on
the list, Dvd drive (2nd slot) to detect for an OS. ect ect. Thus
it could still be a hdd problem and unscrewing and rescrewing will
not resolve it.
Thanks for your reply :)
The hard disk doesnt light up, but I could feel a little
vibration coming from it. Upon close examination, there doesnt
seem to be a place where the hard disk could be lighted anyway.
I tried very hard to hear where that clicking sound came from
and I'd like to think the clicking sound came from the DVD drive,
which has been behaving weirdly as well. It seems to be "busy",
with its flashlight blinking every 2-3secs.
Apart from that clicking sound, there is this whirling sound,
which is completely random. Sometimes its so soft, but sometimes
its audible. No frequency whatsoever.
How do I test which is part is faulty? The graphics card (which
gave me a fair bit of problems last time), motherboard or hard
disk? haizzz.
