I have had my Acer TravelMate for about a year now, and had not had any
problems up until now. Since last week I have had a problem with
60/70+% of the CPU being used all the time. Using SysInternal's Process
Explorer, I was able to see that the cause of this was due to a
"process" called 'Interrupts'.
I have spent a lot of time looking on the internet for solutions to
this problem, but am yet to find one that works... I have tried
disabling all the USB devices in Device Manager as recommended in
another post on this site (a very old post I might add), and this
appeared to work, temporarily! The post also said to try the same thing
with the IEEE 1394 device, I did this with it tried separately and in
conjunction with the USB devices being disabled.
Doing the above stops the process using all the CPU all the time, so if
my computer is idle, then it is fine. However whenever I try to run a
program or anything similar the Interrupts process jumps back up to
80/90% until the program has become stable and isn't doing anything
else.
Other problems that this appears to cause is that when I'm booting, the
system tries to run chkdsk, but every time gets to where it says 0%
checked... and then freezes, but if I skip the scan then it will get to
Windows fine (although very slowly). I have left it on 0% scanned for
well over an hour just to make sure its not just working very slowly,
and it doesn't get any further. I have also tried to run in Safe Mode
and it gets to the same point each time, just after it has loaded
'Mup.sys' and again it freezes.
The problem appears to be linked with accessing the hard drive, as when
I run chkdsk from within windows it runs fine but the interrupt process
is at 80/90% for the duration of the check, but drops down to normal at
the exact point the scan completes. And if I'm playing music on my
computer when a song loads the process jumps up again, but then plays
fine once the song has started playing.
Another post on the site said to try a Microsoft logging program called
RATTV3. Having analysed the results from this (well the best I can) it
looks like there are issues with the following three drivers:
atapi.sys
acpi.sys
ndis.sys
However, I have no idea where to go from here.
If anyone has any further information that might help, please let me
know, as this is very frustrating! I'd rather not have to reformat my
hard drive, and I've been lead to believe that just
re-installing/repairing Windows will not fix this problem.
Thanks in advance for any help you can provide.
