Knowledgebase My computer starts but has an error message on the screen. What can I do? Should I get an Uninterruptible Power Supply (UPS)? Why? My computer is about 6 years old. Can I plan on using it for 3 more years? I need a new desktop for my office. Should I get one from Best Buy on sale? All computers made the same. Should buy an inexpensive one that is on sale? Our server has one big hard drive and seems to work fine. Is there anything to worry about? Our server is out of warranty and is about 7 years old. What would you recommend doing? Is it cheaper to replace an old server while it is still working, or should we wait until it dies and replace it then? Should I purchase a Windows 8 Pro computer, or stay with Win 7 Pro? How often do I need to replace my server? How about my workstations?
