Having problems with your PC Desktops ?

Machine freeze up randomly. Must do a hard shutdown. Seems like a motherboard failure


Answers :

Freezes and crashes are generally caused by some sort of instability in the computer system.

The following is a list of specific problems that can cause instability along with what to check when troubleshooting each.
\015\012Viruses can cause instability.
Run a virus check on the computer to look for a possible virus.

Conflicts can cause instability.
Check the Windows Device Manager to see if there are any yellow exclamation marks or red Xs beside the listings for device classifications. If there are, contact Tech Support.

Buggy or damaged software applications can cause instability.
If the system is less stable when certain software programs are running, shut down those programs and see if the problem continues to occur. If the problems stop, chances are that those software programs are causing the problems.

Buggy, outdated, or conflicting drivers can cause instability.
Check manufacturer web sites for updated device drivers for the various devices installed on the computer system, such as: printer drivers, modem drivers, video drivers, sound drivers, USB device drivers, etc.
Update one driver at a time and see if the system stabilizes. If this doesn't work, it may be a hardware problem, so contact Tech Support.

AC problems can cause instability.
Check to see if the computer system is plugged into an overloaded outlet.
Make sure the computer system is plugged into a surge suppressor.

The installation of new devices can cause instability.
There are three typical symptoms that point to this problem:
The computer system fails to boot, freezes during a boot, or freezes during an operation for no apparent reason.
The system fails to recognize the newly installed device.
One or more software applications fail to function as expected after an upgrade.

Hardware failure can cause freezes
\015\012
Fan failure, cpu failure, memory failure, could be also a cause of freezing.
\015\012
\015\012Keep track of the hardware and software that is added to a computer.
The addition of new hardware and software can often cause problems to occur.
