• Video Data Transfer: Tests the graphics acceleration part of the video controller. This
test fills the screen with 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: Prints a text string in random sizes and colors to test the video device
driver and video controller.
- PCI Test
A Peripheral Component Interconnect (PCI) bus is a fast standard bus that is common in
Pentium systems. The PCI Test is performed to ensure that the PCI bus is working up to
speed. The motherboard is scanned to verify the configuration space and to ensure that the
diagnostics can communicate with the board.
For test procedure instructions, see the 7-6-1-1-7 "PCI Test" on page 7-128 .
- Network Test
A Network Interface Card (NIC) is a computer circuit board or card that is installed in a
computer so that it can be connected to a network. Networks are used by businesses and
some home users to connect PCs together so that they can share files and resources. Data
travels over a network connection much faster than over standard internet connections.
The PC Doctor Network Test will reveal that a network card is present without a driver
installed. These cards are likely to not show up on a PC's list of network cards available for
test. This may cause the test to return a result of “not applicable”, meaning no network cards
were found. The test may detect other issues such as electrical interference (noise), circuitry
damage, loose connectors, and crimped or bad network cables.
The Network Test will test DSL or cable internet connections, which operate within a network
environment. However, this test does not test the DSL or cable modem used for accessing
the Internet. Currently, no PC-Doctor test exists for testing cable or DSL modems.
The Network Communications Test checks if your PC's network card works and if your PC
properly communicates over a network. It makes a list of all the remote PCs on the network that
the NIC uses and sends information in the form of several “data packets” from the tested PC to
the “host” PCs. These “data packets” are then returned by the “host” PCs to the tested PC where
the contents of the “data packet” are checked. If too many of the “data packets” fail to get
returned or are thrown away because of data corruption, the Network test logs as FAILED.
For test procedure instructions, see the 7-6-1-1-8 "Network Test" on page 7-130 .
