PC Randomly freezes every few seconds & slow

June 5, 2010 at 09:55:12
Specs: Windows Vista

I am using:

4GB Ram (3GB for Vista)
Radeon 4670 Graphics card (x 2 in crossfire)
AMD athlon quad core 2.6 GHz
ASRock m3A7 motherboard

I have two hard drives (one internal, one


A while ago i went on holiday, when I returned
home my monitor was not working. It made a
clicking noise when turned on but screen
produced nothing. I googled it, found out its
power supply was broken so ordered a new

All was well untill a week later, when while
watching a movie on my new screen
(upgraded from 19inch to 21.5 inch, and from
standard screen size to 1920 x 1080
resolution (resolution improved greatly))

Anyway, during this movie the pc randomly
froze every few minutes and played catchup (it
quickly showed all the images in a rush to
catch up - because the sound was still

Anyway, it also happens when writing text on
word and can happen during anything (but i
can move the mouse around so I dont think it
is a problem with the screen).

Gradually it has been getting worse.

I recently format my harddrive and reinstalled
windows - but the problem persisted.

I have also noticed that my PC runs slower
when copying files to my internal harddrive as
opposed to my external harddrive.


I dont think it is a software problem.
I don't think it is a problem with my monitor.
I don't think it is a problem with RAM.


I think it is something to do with either the
harddrive or the power supply (according to the
google responses).

However, I don't know and I haven't been able
to replace the power supply or try my harddrive
in another pc.

Any ideas? And do you think it is the harddrive
or power supply? Someone said that maybe
the larger screen meant the GPU was running
faster and required more power, however I have
attempted to disable crossfire and this does
not seem to have helped.

Sorry for th e wall of text.. its quite a complex
problem =(.

I don't know if it says HDD busy.

When I'm watching a movie from the other hard drive it also
slows down randomly.

I could try installing windows on my other hard drive and using
that to run the pc (and unplug other one). I guess that could
narrow it down!

I would first check the system and CPU temperatures.

Boot into the BIOS (setup) and look for a screen there with temperatures and voltages.

CPU temperature was running at 51 degress C in BIos
(possibly went higher).

I have now cleaned the dust out of my case and from the fan.

New CPU tmperature in bios was 39 degrees C. This is about
right I think?

Anyway, still problems with randomly freezing, although the
'slow' problems seem to have disappeared.

Going to run windows performance test and see what the
processor score is! Fingers crossed, although CPU is still
under warranty.

Also going to download a CPU temperature program i can use
to monitor while on desktop.

CPU temp at desktop is running average 35 C, max 44 C.

Windows Index score

CPU, GPU, RAM - 5.9

Primary Hard disc - 5.4


Btw, I didn't mention earlier but although copying files onto my
other hard drive is faster (the external one), it is also powered
by its own power supply.


I'm going to guess the problem is with the power supply, will
be a week before I can find out this is the problem or not.

Thanks for the help guys!

I'll post the result when I find out so other people in a similar
situation can know what do to.

I've been having the same problem with my laptop. I recently wiped it clean and installed windows 7 (from vista) and it was running fine. My impression is that it started when the computer was automatically installing windows updates and the installation got interrupted (ran out of battery power).

I could be wrong about the cause but I have a lot of the same problems as Mark. I can run programs such as games which run fine and don't seem to be affected but when I try to watch movies on media player, kmplayer, real player, any of those and it seems to freeze and lock up for about 30 seconds roughly every 7-10 minutes.
Can anybody help me? any help would be greatly appreciated!

You need to start your own thread here. I suggest you post in the Windows 7 forum.
