Task manager shows the system is running at 100% at all times. The fan runs constantly.
Safe Mode startup work fine...all utilities function properly, however I cannot access the internet in safe mode (or perhaps I don't know how to access it in safe mode).
Norton AV scans run clean. Windows defender is resident program. Ad-aware is non-resident. Both run clean (it takes HOURS for any scan to run, whereas previoiusly I was able to run full scans in 1 1/2 hours)
I did manage to run hijack this, and saved a log file, which I will send if requested.
Your help would be most appreciated.
