Re: Computer Freezes - Power supply?

The number of partitions makes no difference.

Thanks for the replies.

Here are some specs which might help.

- Dell Dimension 5000, Pentium 4 processor with HT technology (3.00GHz,
800fsb, 1MB cache)
- Serial ATA 160GB hard drive (7200rpm)
- 1024MB DDR400 Dual channel memory (2x512)
- 128MB ATI Radeon X300SE video card.

I don't know much about what all this means but would the hard drive,
memory and CPU cope with 5 partitions?

Thanks again

Tim

I press the ON button and the little light turns orange but stays

sinks after several attempts at booting and they are very hot - maybe
overheating.


Do not run it, or even plug it in until it's fixed. This will minimise
damage. I would even entertain sending this one straight to Dell
factory. Is it still under warrenty? If it is, disregard this
following and send it in.

It could either be thermal shutdown, which is easily fixable, or some
short somewhere, or bad psu. So for i'd say your diagnosis is spot on.

The P4 heatsink assembly can be a royal PITA, if you're not comfortable
have a professional do it. This is for the overheat issue.

Unplug all cables (power, video, keypboard, all that), remove the
assembly, remove the old thermal stuff, foil and all that, with
alchohol (the purer the better). Get some Arctic Silver from a repair
shop. Most sell sell it inexpensively. Apply an even layer to the metal
surface of the chip. If you must use your fingers, clean them with
alchohol first, the oils is your fingers attract the silver particles
from the compound, which interferes with its purpose.

Put the assembly back, make sure it's properly reassembled. Plug
everything pack in. Power it on. If the symptoms reappear, it's to the
factory.






Sometimes if I am lucky I can get the computer to load up properly
and
I get a choice of operating system but it often crashes before
reaching
the desktop and doesn't last long if it gets that far.

When I say my computer is crashing I mean that it just completely
stops
in its tracks, you cannot move the mouse and the screen is still -
nothing happens and you have to reboot. Then it has problems with
that
as I wrote above.

I think its either going to be down to the power supply, overheating
or
a virus - I have an out of date version of McAfee which I've been
meaning to upgrade but haven't got round to it.

This is definately a hardware problem. This doen't mean you don't have
a virus, just it's not causing the symptoms with the fans running too
fast and No screen.: )



If anyone can give any help what so ever it would be much
appreciated.
Also I'm not that familiar with techie language so any responses need
to be simple to read and understand. - As many responses as possible
please!

Thanks very much
