Hi Everybody ,

I trying to fix a friends computer where their bios screen freeze
interminatly and very infrequently .

I have so far tested the output of the power supply which all checks out
with a multimeter .

I have run a software test on the ram memory no errors shown but will
try and swap them around to see if it makes any difference.

I have also checked to make sure their is no overheating on the system .

Could anybody else suggest any other likely causes ? I am thinking is
could be the motherboard itself hope I am wrong.

Thanks in advance

johan,

Out of interest, where exactly in the boot-up process does the BIOS freeze?

I have just had such a problem where the screen froze at the Verifying DMI
Pool Data point - for which there could be a number of reasons from BIOS
corruption, MBR corruption, hard disk failing, motherboard failing or loose
connections.

Using XP Home.

It apparently freezes after the it has checked the hard disk from what

my friends tells me so far I have been unable to replicate this fault
although I have discovered that the cpu is running a little hot at 56
degrees when put under load but that is probably separate issue . I
think you right Brian those reasons you give are very plausible ! I have
checked for loose connections . I am begining to think it is the
motherboard as it only does 5% of the time . I will get my friend to
monitor it and see if it does it more frequently !

Using XP home for sure !

Thanks Brian

Gerard,

What are "elcos"?

Motherboard: check for elco's near the CPU. If you see bulged
aluminium caps, that's your problem!
If you see fluid or white powder near the bottom of the elco's,
that's the same problem.
(Elco's are tubular devices with a round aluminium cap on the end
and a plastic coating.)

I have just had such a problem where the screen froze at the
Verifying DMI Pool Data point

That's a very common situation.
Your bios probably has an option 'reset DMI pool' or something
like that. Select it. You have a good chance this will 'fix' the
problem. (This option will reset itself. Enabling it will only
affect the next boot.)

Yes, I've sorted the BIOS out and 'fixed' the MBR and I'm just waiting now
to see if the problem recurs - and if it does, I would suspect the hard
drive as this is a number of years old (motherboard is reasonably new so it
shouldn't be that).

I had a smiller problem, my cpu chip went bad and to frooze up during
the same area. The problem could be related to the RAM being used can
is causing it to lock or freeze in the bios. Try flashing the bois. If
you are sure it is the hard drive. install the drive into your
computer to see if you get the same thing. if you do, the mater boot
record is bad and you will need to fix it. If that is not the case
take a closer look at the RAM, CPU and motherboard. How old is the
computer? what type of motherboard and CPU are is he using?
Good luck.

If it was the power supply the freezing wouldn't
be limited to the bios. In fact most of the freezing
would be during the time when the operating system is
in control.

Try removing and replacing the bios/cmos chip.
That action will clean the connections.
Heating and cooling cycles can loosen socketed chips.
Also, while the chip is out, blow out any dust and
visually inspect the chip legs and socket connections.
