7-5-2-2 Hard Drive Tests
•Hard Drive Test (All)  - The Hard Drive test examines your hard disk drive using a series of tests to 
ensure that your drive can perform its functions.
The following tests are performed on your hard drive to ensure the hard disk controller and the drive 
mechanism are working correctly. The disk surface itself is also checked.
NOTE: The hard drive test can take over ten minutes. •Hard Drive: Linear Seek  - Hard disk drive heads are moved from track 0 to the maximum track one 
track at a time.
• Hard Drive: Random Seek  - Hard disk drive heads are moved randomly several hundred times.
• Hard Drive: Funnel Seek  - Hard disk drive heads are moved in a funnel fashion, i.e., from the first 
track on the drive to the la st, then to the second track, then to the second to last track, then to the 
third track, and so on.
• Hard Drive: Surface Scan  - This test scans for surface defects on the hard disk drive.
7-5-2-3 Memory Tests •Memory Test (All)  - Eighteen test patterns are used to  test memory locations. If errors are 
detected, the address of the block the error was  detected in is shown. During testing, these 
diagnostics will also look out for pa rity errors and other exceptions. These will  be added to the Test 
Log as errors if encountered. 
• Memory: Pattern Test  - PC-Doctor uses several test patterns  to test as much memory as possible.
• Memory: Parity Test  - This test checks for parity errors on  the memory bus during intensive string 
transfer operations. If an error is detected,  the address of the failed block is displayed.

7-5-2-4 CD/DVD Drive Test NOTE: Although the global aspect of the diagnostics a llow for DVD testing, the LOGIQ™ P5/A5/A5Pro does 
not have a DVD drive.(Option)
• DVD/CD-ROM Test (All)  - The CD-ROM/DVD test examines  the CD-ROM/DVD drive to make sure 
it is working properly. You may use either a data  CD-ROM disk or a DVD disk for these tests. You 
cannot use an audio CD, such as a regu lar commercial music CD, with this test.
NOTE: The PC is sometimes slow in re cognizing a newly inserted CD-ROM/DVD disk. It is best to wait a few 
seconds after inserting a disk into the drive before you run any tests. 
There are two types of CD-ROM/DVD tests: 
1.)Seek Tests:  Ensures the drive can access all locations on a disk, and 
2.) Read Tests:  Ensures the drive can read all the data.
• DVD/CD-ROM: Linear Seek - Tests that all locations can be  accessed on a CD-ROM or DVD disk 
in a linear fashion, starting from the first to the last.
• DVD/CD-ROM: Random Seek  - Tests that all locations can be accessed on a CD-ROM or DVD 
disk randomly.
• DVD/CD-ROM: Funnel Seek  - Tests that all locations can be  accessed on a CD-ROM or DVD disk 
in a funnel fashion, starting from  the first then moving to the last, then, at the next pass starting from 
the second location then moving to the next to the last, and so on
• DVD/CD-ROM: Linear Read  - Reads the data on the CD-ROM or  DVD in a linear fashion, starting 
from the start to the end.
• DVD/CD-ROM: Random Read  - Reads the data on the CD-ROM or DVD randomly.
7-5-2-5 Video Test •Video Test (All)  - This diagnostic tests your systems vide o capabilities. This involves testing the 
video memory with 18 patterns, testing your graphics acceleration, and text output. You will see 
these tests being performed on your monitor.
You can cancel this test at any time by hitting the Escape (Esc) key.
The following tests are performed on your monitor:
• Video: Memory  - Video memory is tested by filling the vi deo buffer with 18 test patterns, one pattern 
at a time. The tests will fill the en tire screen with a single color.
• Video: Data Transfer  - This tests the graphics acceleration part of your video controller. These 
tests will appear on your screen as black and white concentric squares and rectangles of various 
sizes and colors. If errors are detected, the locations of the problems are displayed.
• Video: Text Output  - This test prints a text string in random sizes and colors to tests your video 
device driver and video controller.

7-5-2-6 USB Test (Not yet supported)
• USB Test (All)
• USB Configuration Test
• USB Devices Test
7-5-2-7 PCI Board Configuration Test A bus is a set of circuits, wires or connectors whic h connect the various components of your system. A 
PCI (Peripheral Component Interconnect) bus is a fast standard bus which is common in Pentium 
systems. Various tests are run on the PCI bus in  order to ensure it is working up to speed. 
The motherboard is scanned to verify the configur ation space and to make sure the diagnostics can 
communicate with the board.

7-5-3-1 Keyboard Test
1.) Click Keyboard Test  from the PC Diagnostics interactive tests menu.
2.) Click the Test button. A keyboard layout is di splayed on which you can see the keys of your 
keyboard.
3.) Press each key on your keyboard  once and make sure that the corresponding keys on-screen are 
removed from view. If a key on-screen is not re moved, that key may be damaged and you may have 
to have your keyboard repaired or replaced.
4.) To reset the keyboard, click the Reset Keys button. 
5.) To exit the test, click Close.
7-5-3-2 Audio Test 1.) Click Audio Test  from the PC Diagnostic interactive tests menu.
2.) To test the WAV sound reproduction click Left Chan nel, Right Channel, or Both Channels to test 
your speakers. You should hear a guitar chord.
3.) To test MIDI sound reproduction click the butt on under MIDI. You should hear a few seconds of 
recorded music.
4.) Click on the Beep button. You should  hear a low “beep” from your PC.
If no sound is produced in these tests, choose the More Info button in the Audio Test dialog box for 
information about possible causes and solutions.
