No. The problem is resolved.

Hardware Conflicts

Hardware conflicts occur when the operating system detects multiple

devices that are attempting to operate on the same computer resources

when those resources cannot be shared between the devices.

Symptoms:

• Computer hangs or locks up, particularly while using a specific device.

• Memory parity errors occur on parity-enabled computers.

• Noise or other problems from sound cards.

• Unintelligible characters printed on the printer.

• Mouse pointer hangs and will not move or moves in a stuttering

fashion.

• Messages stating that the computer is not operating at maximum

performance.

• Errors and crashes of applications for no apparent reason.

• Nothing displays on the video monitor.

To resolve hardware conflicts, remove any newly added hardware and

contact the hardware manufacturer. Also see your operating system

documentation.

Computer Memory Problems

During POST, the computer checks the computer's memory, determines the

amount of installed memory, and then writes to and reads from the number

of available bytes to ensure proper operation.

Basic Checks:

• If an insufficient memory message appears, save and close any open

files and exit any open application programs not in use.

• Consider installing additional computer memory.

• Run the System Memory test in the Dell Diagnostics.

• Reseat the memory modules.
