HP Pavilion 364 Quick Start Manual page 103

Problem Solution
The computer (or part
of it) doesn't seem to
be working.
Try restarting the computer as follows:
1 Click Start on the taskbar.
2 Click Turn Off Computer.
3 Click Restart.
If the computer shows no response to mouse or keyboard actions, reset the computer:
1 Press and hold the On button until the system turns off.
2 Wait a few seconds, and turn the computer back on.
Note: Using the On button to reset the system is not recommended and should be used only
as a last resort.
A software program, software driver, or the operating system software may be
corrupted, erased, or damaged. You can use application recovery or system recovery
to reinstall the software. Refer to "Using Application Recovery and System Recovery"
on page 79.
It's possible that a voltage spike, power outage, or brownout has occurred.
Symptoms of voltage spikes include a flickering video display, unexpected computer
startups, and the computer not responding to your commands. A voltage spike can
occasionally corrupt or destroy files, so it is a good idea to consistently make backup
copies of your data files. Prevent voltage spikes by installing a surge suppressor made
for use with computers between the power outlet and the computer power cord.
