Motherboard problems

you should tell us more about you're system component
CPU
Ram
Graphic Card
PSU
Hard Driver


either way this should not relate to 32 bit or 64
most freezes for the OS comes from the heat issue (CPU)
check you CPU Fan , it maybe not mounted correctly
, and watch you're temperatures in the Bios
, other reasons could be a faulty Ram,you can check it by running memtest86+
download

her
, other reason could be a weak power supply which cant deliver enough power to the component,
and the last 2 thing it could
you're driver or you're Hard Driver
like the seagate 1 tb driver

I've got an Asus P5Q SE motherboard
Quad core Q8200 PROCESSOR
4GB RAM
250GB HDD
NVIDIA Geforce 8400 512Mb

Its a new pc, do you think the RAM is faulty of the fan? Say i start the pc now, it can freeze at any moment, 5minutes after the boot or 5hr later...I'm really confused about this. Can you please explain me how to run the mem test, please?? I went to the page but got frightened with all these "alien kind"language!


Thx 4helping dear!

ok i will do the job for you

to check the Ram with memtest
this is a direct download for a floppy disk version
[url=http://www.memtest86.com/memtest35.zip][/url]
extract the zip file double click the install.bat file while you floppy disk is in
the program will make ur floppy bootable
it will be good if you read what is written her http://www.memtest86.com/
, ok
for the Temp u should enter you bios by pressing F1 or delet or maybe F2 not sure
you system temperature should be somewhere in hardware information place
or health ,
read you're manual man !.
if the CPU temps are over 80 90C then this should be the problem
,,
or
maybe you have a Bad sector in you're Hard Drive which causing the Freeze
try to make a schedule a scan disk after reboot and look what the report will say when it finish ,if it does report that there is XXX kB or MB of Bad Sector
then it will be you're Hard Drive

if you didn't any successful step
send me a private msg if u want

don't be desperate
think positively ,
you are in progress to find the problem
(find the problem is considered the half way for the solution )

so temps are ok
so skip it
another thing i a want you to check is you Power Supply
if you look at it you will find a list of voltage
and amps
like
v3.3 = 40A , v5 = 30A , v12+= 36A,
something like that and a total wattage like 400w 500w
. tell me what is you're Hard Drive Type
and size
,, another thing you can do
is
reinstall you're driver
,,and tell me what happen with you
i will be waiting for you

Correcttion: It does freeze even if I don't play any video or music file.

It's important for you to tell us how you got this machine.

SInce you can't open the computer, is this a store bought or online purchase, or did someone build it for you? If it's a commercial purchase you need to stick to a software solution for the moment. Was it shipped with the os? Did this problem occur right out of the box?

Try downloading the latest Nvidia drivers for your card. After you've downloaded, be sure to uninstall the old drivers first before installing the new ones.

Did your computer come with the Asus software and utilities disk?

If the video drivers are not the issue then disable or uninstall the Asus EPU-6 and AI software ( if installed) and reboot. There are some known issues.

You may also have a memory capability issue. But again that depends where you got the machine
