Have you checked the ram?

Take out the Ram, if you have more than one stick, then replace them one at a time and power up with on first if it works then add the other one. If it doesn't work, remove the first stick and replace it with the other one and power on again.
This could be caused by bad or dirty ram. (while the sticks are out clean the, with a soft dry paint brush and the slot that they fit into, and when you replace them, make sure that they are replaced gently bur firmly and click back into place)

I hope this helps

No display


This issue can be caused by any of the below possibilities.

  1. Monitor is not on
  2. Computer is asleep
  3. Connections not connected properly.
  4. Monitor settings are not correct.
  5. No Post.
  6. Hardware issue.
Solution: The following is monitor troubleshooting. If your monitor receives a proper display until it gets into Windows 3.x, Windows 95, Windows 98, Windows NT, Windows 2000, Windows ME, or Windows XP please refer to document CH000192.

Monitor is not on

Make sure the monitor is on. If no power light (green or orange light) is seen on the monitor display try pressing the power button until it comes on. If no light comes on after several attempts continue to below connections not connected properly.

Computer is asleep

If your computer monitor was on and you stepped away from the computer and upon returning it was black it's likely that the computer is asleep. Try moving your mouse, clicking the mouse buttons, and/or pressing any key (space bar) on the keyboard to wake it up.

Connections not connected properly

vga.jpgMake sure that you are connecting the monitor to the back of the computer in the 15-pin connector as shown to the right or older computer 9-pin connection.

If the computer is properly plugged in, make sure it's getting getting power.

If you are not receiving power from a known working wall outlet and if the power cord is removable, replace it with the one connected to the computer and attempt to power on the monitor again. If the monitor still does not get power or it is not removable, it is recommended that the monitor be replaced or serviced at a local TV / Computer repair shop.

If the monitor is receiving power, check the status light.

If the light is orange or flashing ensure that the monitor is not in a suspend mode by moving the mouse or pressing a key on the keyboard. If the computer does not get a display by moving the mouse or touching the keyboard, turn off the computer and monitor and reconnect the data cable from the back of the computer, and if removable, the back of the monitor. Turn the computer back on; if you still encounter the same issue, continue reading through the other possibilities.

Monitor settings are not correct

Ensure that the brightness and contrast is turned up or attempt to adjust the brightness and contrast. If adjusting the brightness or contrast has no affect on the monitor continue reading through the other possibilities.

No Post

Does the computer beep when it is powered on and/or does it appear that the computer has activity? If the computer does not beep or beeps abnormally it is possible that the computer itself is experiencing a hardware issue or is exhibiting a No Post.

Steps on troubleshooting an irregular POST or no beeps can be found on document CH000607.

Hardware Issue

If you have followed the above recommendations and are still encountering the same issue, it is likely that the computer may have either a bad video card or monitor. The best method of determining this is to do one or both of the following

  • Disconnect your monitor and attempt to connect it to another computer. This can be a friend or family's computer and/or it can be taken to a service center.
  • Borrow a computer monitor and connect it to your computer. This will not harm the other computer monitor in any way.

If your monitor works on another computer it is safe to assume that the video card or potentially the motherboard within the computer is bad. Steps in troubleshooting a video card can be found on document CH001028.

CANT BOOT . ONLY PROCESSOR FAN MOVING. I AM H/W


Disassemble the machine completely and clean the Heatsink fan, blow away the dusts from the motherboard, if possible use brush to wipe away all the dusts. Reassemble it, but don't connect or install anything on the motherboard except the the power supply, the cpu with the heatsink and the system speaker. Now plug in the mouse, keyboard and the monitor (please connect the monitor on the integrated VGA port on the motherboard). Plug in the power chord on the back and short the two terminals of the power switch pins on the motherboard's Front Panel connectors, i.e PWR and GND with a screwdriver or with any metallic object you think is suitable (shown below):
nonontech_33.jpg


Remember to switch on the mains switch (wall outlet connected to the power supply) and make sure both the power connectors on the mother is connected, i.e. 20 pins and 4 pins.
Check the status on the monitor and listen the beep codes (the system speaker is compulsory for this diagnosis). If you see anything on the display or if you could hear the beeps, note the beep sequence (let me know if it's not 2 beeps or 3 beeps, if it's 2 or 3 beeps, the proceed forward), Switch off the machine and install one memory stick (Ram) and reboot. If it was 2 or 3 beeps, then you should no longer hear them, if you still hear the same beeps, then try with another Ram on another SIM bank(s) [Ram slot] after the machine is put Off and boot again.

If you don't hear anything or you don't see anything on the monitor, then your motherboard is bad or perhaps the integrated video card is dead or it could be the BIOS chip itself. I would suggest you to replace it, as it's not worth repair. Buying a new one will cost you less then repairing this motherboard under such circumstances.

If you see or the beeps continues, try with another working Ram, it should definitely work if the Memory module on the motherboard is still working, otherwise.. I would again recommend you to replace it.

Well, in case if it's successfully booted or the display is ok, then proceed forward by installing the component one by one and reboot everytime you install a component or plug in connector (s). You'll be able to find out the culprit, whether the hdd, or the Dvd/Cd drive or the front panel switches or others.... Will need to replace or will need to repair.

Please update so that I will be able to assist you further.
Good luck.

Just now i shut down my computer normally, an hour later when i tried switching it on again i cannot, the monitor dosent show any image, it even not shows the BIOS, the fan tuns just for a while and then...


It sounds like a hardware problem. Check the obvious like the power cables and plug it into a different wall socket to make sure that isn't the problem.

Does the computer beep when it starts up. The pattern of these 'POST' beeps can help you determine the problem. However if the computer doesn't beep, doesn't activate the BIOS and the hard drive doesn't spin up (with the HD light flickering) then you either have a fried motherboard or processor. Not an easy or cheap thing to fix.

Please help me to identify my problem


The system beeps when you remove the RAM. This means that POST is working correctly and the motherboard may be fine.

Check that the monitor cable connector that connects to the video card isn't loosely connected.

When you insert the RAM, there's no display. This may mean that the RAM is detected but still faulty. Try using another RAM, if you can. Also remove the Video card (if you have a separate video card). Then, re-insert it firmly, and power up the system once again.

If you don't have a separate video card, you should test the motherboard on the bench, that is outside the computer case. Remove the motherboard, RAM and power supply (and the video card if it's separate). Put it on the bench and power it up as shown here:
http://picasaweb.google.com/raspal.century/MotherboardOnBench#

You'd need to closely look on the motherboard to see which pins are for the power switch (marked as PW-SW, PWR, PWR-SW, PWR-ON etc). Then, short them with a screw driver, for a second, to turn the system ON.

Replace the RAM and the video card one by one, if the system doesn't give any display even on the bench. This way you can find out what is the problem.

Hope that helps,
Regards,
Raspal

Comp. does'nt turn on. power is good


Your question fails to provide sufficient information.

.."doesn;t turn on power good...."
do any lights on the pc illuminate
was it working before, and did it close down correctly
has it possibly been hit by lightning
have you recently opened the case to install new hardware?

Possible causes of a failed power up.
dead power supply
a video card not seated in its slot correctly
dud motherboard
motherboard installed incorrectly
no Bios battery on motherboard
faulty wall switch
faulty power pack switch
no ram installed

and on and on

No screen image


You gonna need an spare monitor, video card and a memory card. But first have the RAM card and the video card(if plug in) be clean or reseat. Use clean soft eraser to clean its edge connector, both side. And check your video card for dirt or stock fan if it have. Do this cleaning when unit is off and unplugged to wall socket even UPS. Also reseat the monitor cable. Then try to power it up again.

Next step;

And since it beeps it seems one component is failing or loosing its contact with the board. Then use the spare ram, then the spare card, if still not viewing any try to swap the monitor.

Or if you have no spare if cleaning only doesn't help, its practical to bring it to the expert.

Asus K8N-LR power problem


This is a problem within your ATX power supply . Better to get it repaired or replaced , otherwise each switch-on surge would damage your comp components eventually .

Brand new motherboard wont start up


Hi,
try taking 1 stick of ram off the motherboard, and boot up with 1 stick in slot 1 or 2.
You should get some beeps, 1 is system Ok.
3 is usually RAM/Graphics problems.
Also try booting with the motherboard setup disk in the CD Drive, it may be looking for files to initialise the Board.
And the obvious, check that all cabling is correct from mainboard to front panel. Power on/off Reset et,c.
View the user manual to see if the board has any jumper/dip switch settings for different configurations.
