I reset the MoBo as outlined in my MoBo's user guide . I also removed the battery as well. the BIOS has the latest update according to the ASUS website , I double checked the sticks for compatibility and the are list as compatible with my MoBo. still no luck.
After I posted my original post i googled my problem again to see if there might be a chance there was something new I could try. There was just the same stuff as I had tried before .Mind you I have tried this before with no luck , but I tried it again, I went to the system configuration /BOOT tab/advanced options and unchecked the box maximum memory hit ok then apply then restarted the computer. I opened the task manger and much to my amazement it showing all 8 GB being used. The next day when I started up the computer I checked the task manager and it was back to my original problem. It was working for a short time. Your help on this matter is appreciated
I will try Neemobeers suggestion and get back to you. Thanks
