I updated Nvidia Drivers/Office XP SP3 just the other day. After a reboot, computer was running SLOW AS. Checked task manager to find CPU usage was at 100%, due to Explorer.exe . Have run Adaware/Spybot S&D/Norton 2006 scans and they have turned up nothing. Iv checked the location of Explorer.exe using hijack this and its in system32, where it should be.
There appears to be no virus/trojans/spyware or anything on the computer. Next i disable startup programs to see if one of them is conflicting with Explorer.exe. After disabling "RaLink Wireless Utility" the problem stops, but so does my internet, as this program runs my wireless lan card etc etc.
So i plug some lan cable into the back of the comp and attach it to the modem directly, the problem is gone.... BUT around an hour later it returns. I find Explorer.exe is using 80-99 cpu....I have no option but to close the lan connection for the modem, kill explorer.exe and then reenable them both - it lasts for another hour yet again.
I have no idea what to do next, its obvious that SOMETHING within the internet connection (config) is triggering this high CPU load for explorer.exe, but what... and why is it instantanious when the wireless network software runs and yet it lasts for an hour when the modem is connected directly?
Iv checked basically everywhere i can on the internet, including many similar problems to mine (such as the .avi glitch) but this is not the same as what i am experiencing.
Please, i need ideas and (alot of help with this) Hopefully you guys can be my saviour?
