<span style="font-size:18.0pt">TROUBLE Shooting First System Power-On</span>
The system will
not come up at all, the display is blank and the computer does not make any
beep sounds from the speaker.
<span style="color:blue">Solution
1:</span> Check the power connectors to the case, the MONITOR... and to
the wall and on the Mother Board. Are any lights coming on at the monitor,
case? If not, then you may have popped a circuit breaker in your house or
office. Try plugging in a different electrical device or multi-meter to
check the power... it should be between 115 and 120, over 125 can easily FRY
a computer and other electrical devices. If the lights are on, and the power
seems to be fine, then you need to determine if the fan in the power supply
coming on? Is the monitor powered on? Is the monitor's video cable plugged
into the video card? Double check the brightness and contrast settings. Plug
the monitor into ANOTHER computer if possible to verify the monitor isn't
the problem.
<span style="color:blue">Solution 2:</span> Are any of the drive
lights on - floppy, hard disk, or CD ROM drives? Did they flash during power
on? If yes, then it's probably not the hard drive or cabling... if they are
staying on, there a definite problem. Check the BIOS settings. Maybe the
battery is dead or too low. If the BIOS is correct, trace the cables and
double check all of the connections and jumpers. Make sure that it did not
miss any of the pins when it was installed. Also, make sure that the power
connector is on properly, remember "red towards power" on most drives.

Solution 3:</span> If the monitor is working fine, and all of the rest
of the stuff checks out, chances are - short on the motherboard, bad power
supply, or PC speaker connected wrong. If the PC speaker is wrong, you
wouldn't hear the beep codes.
<span style="color:blue">Solution 4: </span>
Verify that all of the EXPANSION cards are fully seated in the slots. A
partially inserted card can cause the system not to boot - power supply fan
may be on, but the monitor is black (blank) without any messages. If all the
cards and cables are correct, and the system is STILL not working...
<span style="color:blue">Solution 5:</span>
Try unplugging and disconnecting everything except the motherboard, PC
speaker, and video card... if it doesn't power up here, then check the RAM,
video card, motherboard, and power supply. <span style="color:blue">
Solution 6:</span> Try a different power supply - this is a very common
problem. Today's power supplies are designed to give up their lives to
protect (save) the rest of your computer. Also, most of the new power
supplies being sold today we tested do NOT pass the basic tests, and use
many short cuts to reduce the cost. <span style="color:blue">
Solution 7:</span> Replace the system RAM, or move them to different
slots.<span style="color:blue">
Solution 8:</span> If all else has failed, replace the Mother Board
itself. This is a very rare problem, but does occur in once of one-hundred
plus boards.<span style="color:blue">
Solution 9:</span> Try a different CPU - also extremely rare... in 20
years, I have only seen this twice on a system that was previously working.

The
system sounds like it is BOOTING but there is no video display.[/url]
<span style="color:blue">Solution
1:</span> Verify that the monitor is connected to the computer and
power, and is turned on.
<span style="color:blue">Solution
2:</span> Check that the brightness and contrast controls are NOT at the
lowesThis is totally unreadable. Please check what you are doing and don't do it again.
