condition. – Control Panel is your friend:
• Hardware – Keep screen clean, blow dust from heatsinks and fans – Overheating can cause many problems – Use Speccy to check temperatures

– Remove unwanted programs, especially those that run at startup
– Cleanup unused files – Disk Cleanup Tool
– Cleanup Windows Registry and unwanted files - Use a free tool like CCleaner
– Minimize Graphic processor load – PC runs faster
– Make sure only 1 printer connected- easy to have multiple unused printers
– Check Power/Battery options - when using battery in a laptop often reduced performance as
default to extend battery life. Should have high performance set for when you plug in laptop to power

Software Updates for Your PC
Computer Backups 1-2
Backup of your computer system and User files provides you a way to recover if your
system fails or is compromised. Backup Basics:
• Hardware choices to store backup • External Hard Disk simplest and easiest to set up – approx. $100
• DVD’s - good long term storage but will need many of them(4.7GB/disc)
• USB Memory stick –specific files and folders (e.g. photos, documents etc.)
• Use 3rd party via web ,Cloud backup. - Someone else stores your information
• What to store in a backup • System - Windows 7 or XP backup disc to allow recovery after major system failure.
• User Files/Folders – typically
• My Documents, My Pictures/Music/Video
• Application specific files not stored under above
• Email in/sent box and contacts if NOT stored on server like GMail
• Browser(IE/firefox) bookmarks, Skype contacts etc.
• Social media postings, calendars
• Frequency • Automated best, typically weekly or incremental

• Run Windows 7 Performance assessment • Lowest numbers will show you where to upgrade
• Top Hardware upgrades to improve performance • More RAM
• 32Bit WinXP/Windows 7 - try to get 4GByte installed for best performance
• 64Bit Windows 7 - try to get at least 8GByte installed
• For Windows 7 can also use USB mem stick to RamBoost system
• New Graphics/Video card to support HDVideo & windows 7 aero • Look for 1-4Gbyte Graphics/Video on-board RAM
• On a PC consider upgrading CPU to faster version • However may not be cost effective and may need faster RAM
• Larger and faster Hard Disk • Old discs 5200rpm and ATA interface (0.8GBit/sec max)
• Newer discs are 7200rpm and SATA (1.5-6GBit/sec)
• External Hard Disk for Backups – connect via USB
• USB 2.0 or USB 3.0 interface cards
• Gigabit interface cards for high speed networking
• BlueRay and/or multi-standard DVD/CD Read/Writers
