At various times, without warning, the processor appears to go into overdrive and I can’t do a thing until it stops. The Resource Monitor shows processor usage up and down during this time but only somewhere around 5 to 30% on average. It freezes for around 30 seconds and then it’s fine for a while.
The problem usually happens when I`m online and I get a ``resolving cache`` message at the bottom of Google Chrome. (Probably because that's what I spend most of my time doing.) But it has occurred when playing low demand games like Microsoft Chess or Mah Jong or running music on ITunes. It just did it again and at the moment I`m using Word. It happens once every couple of hours on average. But it’s always when I’m in the middle of something. For example it did it today when I exited Mah Jong.
I’ve upgraded all the drivers and the BIOS to the most recent versions.
Here are the specs of my notebook:
Acer Aspire 5553G
AMD Phenom II N830 processor 2.1Mhz
AMD M880D Chipset
Running Windows 7 Home Premium 64 bit Version 6.1.7600 Build 7600 (Fully Updated)
500Gb Western Digital Hard Drive WD5000BEVT-22AORTO ATA Device
ATI Mobility Radeon HD 4250
(I`m guessing this is integrated into the chipset)
ATI Mobility Radeon HD 5470
Matshita DVD RAM UJ890AS Drive
Broadcom Network Adapter
Do you think it’s a hardware of software problem? Any advice on tracking it down?
