Hello MAP

I've just finished running antivirus (AVG and ClamWin) and spyware (adware
and spybot) verification. I've manualy

verified that I don't have the dlder virus in my system. In fact, I'm not
even suprised, since I've been trying to

install and configure XP and I haven't had time to surf the net or do
anything else.

Actually, the synthoms I observe in my system are different than those
listed there. While many people report that

Explorer.exe gets more than 90% of CPU, after some time, in my system it is
always the same behavior. Every few

seconds, Explorer.exe gets some CPU (Taskmanager show only 2-3%) for almost
one second and then releases it. This

cycle happens since boot time. Everything that is running in the foreground
when this happens freezes for almost

half a second (ie a sound playing, a menu opening, a window moving, the
mouse pointer travelling).
The process monitor shows that at these times, the CPU has 20% peek
processing time and also there is an interrupt

process time of 20% at peek. The form of the graph is a thin triangle.

Does anybody know how in the world I can locate what process, DLL or driver
that is doing that? Is it possible to

monitor what IRQs are firing at those moments?

Yesterday I was desperate. I launched system monitor and task manager. Then
I started to kill every process in an

order that I thought was of "decreasing importance". Suddenlly, when I
killed of the svchost processes the system

monitor stopped showing those nasty triangles every few seconds. However, a
few moments later, the system showed a

dialog box, sating that the system had to be rebooted because some process
had suddenly stoped. Those 40 seconds or

so were the only time that my system behaved without the hipcups!

I wonder if the SVCHOST that I killed was indeed causing trouble or if it
was so vital that the monitor didn't work

anymore at that time.

Please, is there anything I could do to determine what process, driver or
piece of hardware is causing all this?

Again, Windows98SE worked without a glitch and so does Linux in another
partition. Do I have to downgrade back to

Win98SE and lose NTFS?

Thanks in advance for any help,

RS

HEEEEEEEEELLLLLLLLLLPPPPPPP

Does anybody know, at leastm how to find out what process is executing at
those intervals or at least, wht process is servicing which interrupts?

Thanks,

RS
