The Symptoms: After booting I may work for a few hours without a problem. Then an application (e.g., maxthon) will suddently and for no reason I can see - go to about 90% CPU utilization which effectively brings all work to a stop. The strange thing is these symptoms do not appear to be related to any application - the same events can occur using almost any app - including Process Explorer, Process Monitor, Windows Media Player, etc. And...these apps may have been working before without a problem.
After this happens, I usually kill the process and can contirue working. But about a third of the time, this is the begining of 'the end' . Meaning that ANY process I load afterwards will immieadely go to 90% cpu. And sometimes I can no longer even kill the process because I cannot launch Task Manager (I actually use Precess Explorer.) So I then power off/on and wait till the next occurence.
My PC info: P4, 1gbRAM, CPU is not overheating and memtest passes; XP Pro, SP2, Comodo Firewall, AnitVer, Spybot Search+Destroy. Maxthon browser. I use AutoRuns and Starter to make sure I know what is loaded at Startup. No Virus/Malware detected.
My Thoughts: I may have caused this by running Regseeker in 'Autofix' mode. But I don't recall exactly when or what caused this poblem to begin. I have a few old registry backups, but have added software since then and don't know what doing a registry restore will do. I also was no using XP System Restore. So at this point I don't think 'rolling back' is a real option. After many years without a real backup/restore plan I now realize I need one (which will be another project after I get this CPU problem fixed).
Thanks for any suggestions.
