For the past month or so, several minutes after coming out of standby, I
start to experience excessive CPU utilization. I can't pin this down to any
process, or to any specific software. Typical normal CPU utilization is only
about 1% or 2% on my Dell Inspiron B130 with Intel Celeron M processor and 1
GB of RAM. When I get this excessive CPU utilization, idle CPU utilization
(no activity) is more like 8% to 12%, and when I try to do virtually
anything, it spikes to anywhere from 50% to 100%. For instance, if I try to
do anything in Quicken 2009 Deluxe under these circumstances, qw.exe spikes
for anywhere from 2 to 30 seconds. Similar things happen with ANY other
program, such as Mozilla Sunbird 0.9, Mozilla Firefox 2.0. The only thing
that helps is to reboot, but......
Sometimes, even after reboot, the problem still is there. Also, whereas a
typical reboot takes about 90-120 seconds, a "problem" reboot takes 5 to 7
minutes to complete. Sometimes it takes multiple reboots to resolve the
problem, but it (so far) has always resolved.
Today, I tried running a memory tester (memtest86+), and it came up clean.
I ran 3 malware programs in safe mode (AVG Free 8.5, MalwareBytes'
Antimalware Free, SUPERAntiSpyware Free), and they all came up clean. All
prior scans in normal mode have been clean. I have never had any malware
detected on this system in 4 years.
I would appreciate any suggestions as to where to look, or what software
might be useful in trying to pin down the culprits here, or what other
information you might need. I am running Windows XP with SP3.
