Have quad core only one processor shows in sys info but four in device mngr.???

yes it is normal.

Related question: When I monitor CPU usage (using task mngr) while doing very intense photo manipulation, the most I get is 25% usage. This leads me to believe Windows is only recognizing one core. ????

Do you have 4 cpu graphs? You should have one for each core. What program are you using? Most software, especially if its older can only use one core, there for 25% of your processor.

No only one. I did get over 60% when using photoshop, as opposed to Corel Paint Shop Pro which only went to 25%. Do I need to reinstal Windows? I tried to delete the cpu from devise manager then restart but still only one processor shows up in system information. Help!!

Thanks so much. I tried it and 4 at 100% showed. I am guessing that means all is well even though system info only shows one cpu?

yes.... yes and yes for the last time. it is fine.

Whew.....
