The Dell OptiPlex 755 may not wake up due to several reasons, including power supply issues, faulty hardware components, or outdated drivers. Additionally, incorrect power settings in the BIOS or operating system can prevent the system from waking up properly. It’s also possible that peripherals or connected devices are causing conflicts. To troubleshoot, try resetting the power supply, updating drivers, and checking BIOS settings.

How many slots for memory are on a Optiplex Gx260?

There are two slots that can hold up to 1GB each in the Dell Optiplex GX260. It takes DDR PC2700 or DDR PC3200. I found out at crucial.com. It is the direct outlet for Micron Technology. My PC used to have 128mb. I added 1GB. The time it takes from my PC to bootup dropped from 3-4 minutes to 30 seconds. The web surfing speed increased, too. Crucial can scan your PC and make recommendations. The price and quality can't be beat. It's a good place to buy memory. http://www.crucial.com/store/listparts.aspx?model=OptiPlex%20GX260%20Series
