Thanks for your responses.
Please see my answers inline (with snippage):
Malke, if there is a problem with hardware then the computer should
not work at all.
This is not correct. Random lockups are usually caused by hardware.
"Random" means they don't happen regularly so it is quite possible to
be using the computer. You could also have a driver problem, but
software issues usually occur at the same time when doing the same
thing.
I am not sure if this means that its working fine. Are there any
Software
Tools to check the Heating problem of hardware like CPU, HardDisk
etc.?
Google for motherboard monitor.
About "computer heating up", I think this might be the cause because
during week days I hardly use the Home PC. This problem happened
during last weekend. I need to observe this weekend and see if I get
the same problem again.
Overheating is a prime cause of lockups, yes.
1 Question - are you guys aware of any hardware diagnostic tools for
Intel Motherboard? I don't remember if Intel has any such tools which
can test Motherboard and CPU.
Google "Intel motherboard monitor". Also go to Intel's website and see
if they have one.
From the time I have got this PC, I get lot of humming noise from the
PC cabinet. Is this common with a P4-3GHz HT processor?
There is no way to answer that question. All computers make some noise
and all are different. It isn't possible to say what is normal for your
specific computer. Processors by themselves don't make any noise - it
is the fans and hard drives that make noise. Hard drives don't usually
hum; fans do.
