Title: PC won't boot anymore
Post by: Bookwolf on May 28, 2005, 07:22:36 AM

This morning, I discovered a problem with my PC.  It basically won't boot.

I press the power button, and I hear the fan come on, and that's it.  My monitor, keyboard, mouse and speakers all act as though the computer is off.

The strange this is, last night it worked absolutely fine, and in the 8 months that I've had it, there have been no problems, even when it came to installing a new OS.  

Does anybody know what it could be?

Do you have virus protection? Have you checked your monitor connection etc.?

Of course I have virus protection, and on top of the fact that most virii are targeted towards Windows helps too.

I've checked all the connections, unplugging everything, checking the connections and plugging back in, and it still doens't work.  It's very odd, because the computer was off all night, so theoretically it should be in the same condition as when it was on, last night.

I suggest you reset the CMOS.

To do so follow these steps:

1. Flick the I/O switch located on the backside of the Power Supply Unit.
-- If there is no such switch located unplug the power cable
2. Open the system case
3. Search the mainboard for a CMOS battery.
-- If you can not find it or do not know where it is, refer to your mainboard manual
4. Remove the CMOS battery for approximately 10 to 15 seconds.
-- Be extremely careful when working inside your computer take into mind that an electro static discharge may damage components. To learn more about ESD see this (http://www.computerhope.com/esd.htm) article.
5. Place the CMOS battery back into the holder.

Additional:

If your CMOS battery can not be removed, or you do not wish to remove it search through your mainboard manual for information on how to short circuit the CMOS jumper. The CMOS jumper may not be present on all mainboards.

Just tried that, took it out, left it out for about a minute, and then tried to boot again, but it didn't help.  Same thing happened.

Suggestions:

1. Remove individual hardware components to eliminate problem.
2. Have the Power Supply Unit tested
