Hello, Shadowshane Hi, try replacing the power supply box. Use a much higher power supply. never buy just ask or lend a PS box for a moment.

hope this helps

Try updating window media player to the latest version.

It might be a virus.
Probably Lsass virus. This virus can get into your computer and really cause havoc with your network connections and also deny you access to certain internet sites.
You need a Lsass removal tool.
try to go here http://www.symantec.com/security_response/writeup.jsp?docid=2004-050114-1706-99
and download the tool, and follow the instructions.
good luck

this problem is cause by some hardware components. just make sure all of your hardware components are fixed correctly with mainboard. or else, if you installed any new hardware options to your computer, just remove that & try to start the computer.
if you still have that problem, just let me know!! 

aw I think you have problem in hardware, software or user.. hardware means there are parts of your computer hardware that have a glitch or uncompatible, software maybe you have been virus or you installed uncompatible programs, user unproper management of computer like unproper shutdown.... that cause the system or hardware to crash....

Try booting in safe mode by pressing F8 when you turn on or restarting the computer, if a boot selection appeared select your primary hard disk then select safe mode.. after good start up in safe mode uninstalling the new software that you install if there is then restart the computer properly. if you install a new hardware try to take it out and turn on again the computer... TY

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.
Viruses 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Buggy, outdated, or conflicting drivers can cause instability.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.

Some Tips for Dealing with Freezes and Crashes
Keep 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.

Research the compatibility of new hardware and software with the existing computer system before purchase and installation.

The older a PC, the more likely it is to crash.

When a computer freezes or crashes, chances are that changes made after the last save and when the freeze or crash occurred will be lost.

*************************************************
I suggest to you do the follow:

Start up your computer and before windows load hit F8, then select SAVE MODE

On SAVE MODE, uninstall all innecesary programs or recently installed, Clean your computer, and be sure that your computer is not virus or spyware infected.

After that reboot and work normally
This will be fixing your problem.

If the problem after that continues is probably then that your have some hardware issue.
