System shuts down without warning!

So my pc just shutdown without warning, Which is quite worrying. I googled it, town me to go into my Control Panel\System and Security\Administrative Tools\Event Viewer so i did

I got a WMI error saying
Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.

Then almost exactly 5 minutes later the pc shut down.
Now i have no idea what any of this means and would greatly appreicated it if someone could help me out. Im also sorry if this hasn't been posted in the right thread!
Thanks mick!

  1. no this is in the right thread... has this happened more than once?

    also look at this and follow the instructions

    hmm how long have you had the computer and do you still have the windows installation cd... if you do then try and reinstall windows... read through the thread i posted to see if there was an answer

    so i read through it and i think you should run this test(memtest) i think your ram is screwed up
  2. have you cleaned the dust out of it ever?
  3. no i think its his ram on the 7th page of the thread it says he fixed it by rearanging his ram
  4. I've ALWAYS had RAM problems just havent really got round to replacing it, Im actually convinced that its my memory now. Only had the PC for like 4 months, really dont think the dusts got to it yet :p
  5. yeah... so get the ram fixed, have you run MEMTEST?
  6. Thanks alot for all the help too!!
  7. not yet no, I'll have to read about how you do it first haha
  8. you have to put it on a flash drive and boot off the flash drive
