I am running Windows Xp with SP2. Suddenly, system hangs when booting. It also hangs when running last known good configuration. In safe mode, booting stops on jgogo.sys, with message “Press Esc to cancel loading sptd.sys”.
Hibernation is a feature of Windows operating system. When you hibernate computer, content of RAM is saved to hard disk before power off. When you turn on your computer next time, system will be restored to the state before powering off. This means that all programs will continue executing as nothing happened. Restoring from hibernation i usually faster than normal boot. Hibernation feature takes the same amount of space on hard drive as you have RAM installed.
To simplify printing you might need to change your default printer. You can change default printer to any printer you have connected to your computer, or to network printer, or to virtual printer (such as pdf or bitmap printer).
Firewall protects your computer from intrusion by filtering incoming and outgoing traffic. It can be implemented as software or hardware. A hardware firewall is usually a box sitting next to your physical network connection (like DSL or cable modem) and local network computers are connected to it directly or though router or switch.
Internet Connection Firewall (ICF) that is built into Windows is software firewall. This means that it is a software application that runs on your computer and filters network traffic. First you need to enable it and set it up.
Windows operating system is using part of your hard drive as a virtual memory. When Windows runs out of physical memory it starts to swap out data to virtual memory, which is a file on hard disk (pagefile.sys). Hard disk is much slower than physical memory, so when Windows start using virtual memory everything slows down. Remember those moments when Windows stops responding and hard disk light is always on…
One solution is to add more physical memory; other is to optimize virtual memory.
