At least that is how I usually get red on my Task Manager. It's just informational and not a warning or anything I think.
I have an eMachines T6524 AMD Athlon 64 3500+ 2.2GHz / 1GB DDR / 200GB HDD/ Integrated ATI Radeon Xpress 200 /Windows XP Media Center 2005. I have added the following An Xtra 1 Gig of DDR ram and the PNY Geforce 7600 GS graphics card. When I check the task manager and click on the perfomance tab, in the graph bar CPU Usage History there there is red and green. Never used to see red before only green I'm assumming It's not good. Any comments/suggestions would be greatly appreciated.
