CPU fan & PSU fan working but No display coming to the screen


There should be some sort of beeps then. No beeps is an indication the CPU or RAM is not seated properly. You need to refer to board manual if there are beeps.
There is also the matter of... Never mind I just noticed the CPU is an 8 core CPU, but the board supports quad core.

Hello you can download a manual here:

http://www.asrock.com/mb/VIA/P4VM800/?cat=Manual

You need adobe reader to read the content.

My guess is the power supply is failing try to change
it with one you know works.

Look also for bad capasitors on the mainboard:

They should not look like this.

If this is the problem the mainboard must be replaced.
It will exeed the price for a new mainboard to let them be changed.

Good luck

I want to upgrade my cpu for this mother board from 1.8 ghz to 2.8 ghz. What cpu should I go with. Am I going to run into problems with the bios or anything else. Also need to know if I can upgrade...


Here is a link for your mobo

http://www.asrock.com/MB/overview.asp?Model=P4VM800

looks like you can use any intel processor as long as its a socket478 by intel

Check out nvidia agp cards at www.nvidia.com You can get a 512mb card agp.

The bios is plug and play which should not be a problem.

You may need to upgrade the memory also.

P4vm800 not working how to solve this probelom


Good day sir, hi, lets make sure first that your motherboard is good, so we need to test it, just prepare the folowing items.
  1. A good working power supply, to test: place a jumper wire across the green wire and any black(or sometimes the red with work) wire on the 20/24 pin power connector. Plug it and see if the exhaust fan run.
  2. A good set of Ram, just make sure its good. if not or in doubt buy new one (only one module) if you want. (you can keep the doubtful ones and test it later)
  3. A keyboard.
  4. If your motherboard has no VGA onboard, A good VGA card.
  5. A thumb speaker, or you can use your PC case speaker.
Okay lets assemble, on a table:
  1. Place your motherboard, (make sure no metals underneath) connect the Power Supply 20(or 24) pin to your motherboard and the 4 pin 12v connector. (if your motherboard has one).
  2. Connect the pc thumb speaker or your case speaker.
  3. connect the keyboard.
  4. connect the RAM, make sure it clicks as you install it.
  5. Optional VGA card. Onboard vga will do. Connect a monitor. plug in the monitor.
Okay, plug in your power supply, (exhaust fan is off at the moment) locate the power button pins, short them with a screwdriver. (fan is now on)

Now check your Keyboard. you will see two sets of lights, first set is Num Lock + Scroll Lock + Caps Lock, then a few seconds the second set: Num Lock only. at this point your motherboard is good.

Also check out the PC speaker beeps.
  • 1 beep mean good.
  • 1 long and 3 short beeps VGA is bad. (it may help if the VGA is snug and fit on the slot). If on board VGA, use a new AGP/PCIe card.
  • Continous long beeps. cannot detect memory
  • Continous short beeps, motherboard. (or memory sometimes).
  • No beep, fan is on.at this point do everything again. (do it several times until the board responds)
Hope this helps you. feel free to ask again.

No beep,No Display on my monitor,only CPU heatsink fan is moving


have you thought about changing the battery on the motherboard, also checking that the fan on the cpu is seated properly with enough heatsink paste as both these issues will stop the pc from booting

Error signal ASRock P4VM800


When you open to you're bios menu, either at the top or at the bottom of the screen will be a name of you'e bios. In you're case the name is at the bottom of your bios menu. (American Megatrends Inc.). Or for short AMI You could search google for, AMI bios beep codes.
And you can click on this link, which shows what AMI say's about 3 beeps.
http://www.bioscentral.com/beepcodes/amibeep.htm

You need to test you're memory. (Only if cleaning the memory has did not change the beep error beeps).
First remove you're memory & blow out the DIMM slots with canned air. Clean the copper on the memory with house hold alcohol on a lightly dampend cotton swab. (Let it dry), (Do not touch the copper with you're fingers. Re-install you're memory.
If you have more than one DIMM. Remove the bank farthest from the CPU & boot the PC. Did you hear the 3 beeps? Remove the the next bank & re-install the one you removed first in to the slot closest to the CPU. Boot the PC, again did you hear the 3 beeps?

If I can be of more service, just post back & let me know how thing go.

Good Luck!

Mike
