sudden shutdown....CPU usage 100%

December 26, 2005 at 00:25:14
Specs: win XP, intel pentium 4 proc 3.0g
I was surfing the net when suddenly my laptop shut down.When i tried restarting it ,it seemed to take ages..... and when it finally loaded all the drivers and exe files (antivirus and stuff) ,i found the CPU usage was 100%.At this time i disconnected the internet connection but the problem persisted.Theres one thing I noticed,no users were shown when I clicked 'users' in the windows task manager!! could it be that my PC was being hacked? Norton antivirus did not show any viruses after a full system scan and neither did the microsoft antispy detect any spywares..... Please someone help! Im frustrated!

Check your task manager and see what is consuming most of the CPU resources and post back.

I am having the same issue. My laptop gives me no warning just shuts down, but cpu usage is frequently at 100%. The following are files taking it up to 100:
cisv.exe
svchost.exe
crss.exe
system
Just to name a few. There is not one file that is causing the problem that I can see.

I have same problem, but no programs are showing in Task Manager that are taking that type of memory.
