Question about Pioneer ECS P4VMM2 V3.2A P4(478)/FSB 533/VIA/SDRM+DDR/A&V&L/MATX Motherboard (MBEP4VMM22)

1 Answer

Computer won't power on

Okay I replaced HSF, seated correctly, Checked the PSU working fine (it will power up my computer). Disconnected everything except HSF and tried to power up - no response, no fan activity on either HSF or PSU.

I am guessing this means the motherboard is fried?

If so does anyone have a suggestion on what is a good but reasonable priced motherboard. Devices attached to system are HDD, CD, Front USB, Floppy Drive, and extra drives 4 removable disk drive unit (similar to my media player set up on other computer).

    The motherboard is actually a P4VMM2 V1.3 with a socket 478



    The HSF fell off it was never attached properly (held in place by a plastic tie down strap).

  • Skoash Jun 21, 2008

    Okay if I connect each piece of hardware individually to my other computer and verify that it can power on (thus eliminating hardware/device).



    My only concern is my other computer is an HP Media Center PCm260n (although it is not the latest and greatest) will the devices from the V2 Premier (HDD, CD, etc) be compatible with my other computer setup (I mean should they at least power on) without risking damage to my HP?



    I am assuming that this is the only way to rule out hardware faults and basically narrow it down to CPU/motherboard?

  • Skoash Jun 21, 2008

    I should also add I tested the PSU in my HP and it powered that computer up but wouldn't power up the V2 Premier

  • Skoash Jun 21, 2008

    You have answered what I needed. I was concerend I would blow my HP. I guess I will look to purchase a new motherboard and CPU for the Premier.



    The motherboard is a P4VMM2 V1.3



    The CPU says Intel P4 24Ghz/512/400/1.5V



    Just need to find one similiar or compatible with this any suggestions (This Premier is a friends computer just trying to help out)



    Thanks

Well assumomg you letf the psu power connected to the motherboard and turned the machine on using the power switch (which also should be connected! I know it sounds obvious but a lot of the time people genuinly forget!) and then there is no power to the fans, the possibles hardware fault could be the motherboard or the CPU.

    I think you've really answered your own question. I would not risk putting your CPU or RAM into another motherboard without checking they are compatible first. If you can provide me with the following details, I will do my best to find out if they are or not.



    1) The CPU and RAM detail that are in the Premier

    2) The model number of the HP Motherboard.

  • Simon Vann
    Simon Vann Jun 21, 2008

    You need a board with an Intel 478 socket for the CPU. Any of the main brands should be fine. Be sure to check compatabilty with the RAM modules and any drives.(although the drives should work on any motherboard) You check this online fairly easily.



    Regards

E-machine et1161-05 won't boot


Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Test all leads that attach to your hard drive power and data cables IDE SATA the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty Make sure all leads that are attached to your dvd\cd floppy drives have secure connections and are not faulty or just replace them they could be faulty. Computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer error. Even something as small as a faulty electrical or fan lead can cause you problems Motherboard and a Hard Drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail. Check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in.

Computer wont boot all the way up


There are several reason why a computer won't boot up. First you need to figure out if your Power Supply is working, if your not a computer expert, you can try another PSU to test. Or you can use a PSU tester to test if your PSU is still working. If not, clean and reseat your RAM, if you have 2 RAMs, remove each RAM then try 1 RAM at a time, and try to seat the RAM to different slot. If not luck, clean and reseat your graphics card. If you have a built-in video port, remove your graphics card. Still won't boot? try resetting the CMOS. This might fix the problem.

Looking for circuit for Dell inspiron 1520 to trace power from psu, it isnt reaching the computer or battery could be protection diode ( if there is one)


I'm not sure how you checked the PSU but it is often the case that the voltages measure correctly but the PSU still will not work in the computer. I had one recently.

I would buy a new PSU and replace it. If it still does not work, you can return the PSU. Unless you have a complex PSU tester, I would put my money on the PSU being defective.

Amber light is flashing on my computer and it won't turn on at all. Help!


The Dell Dimension 300 gets the amber blinking light when there is power to the computer (the power supply) but the motherboard isn't getting the correct power. Sometimes it can indicate a motherboard fault or that the power supply is not set to the correct incoming voltage.

Check the back of the computer. If the power supply has a switch for incoming voltage, make sure that it matches your incoming voltage. Next check that the main power cable (20 or 24 pins depending on the computer) is fully seated on the motherboard. (It can only be connected one way and should lock onto the connector on the motherboard.)

Next check that the power supply is providing the correct power. You can simply install another power supply (known to work on another computer). Make sure that the PSU is correctly sized for the computer components. Alternatively use a multimeter or a dedicated power supply tester or put it in a different machine.

If the problem is not cured with a new PSU, the motherboard has a failure. Unfortunately, it's difficult to identify the exact bad component. (If a major component other than the CPU on the motherboard had failed, the diagnostic lights or beep codes could help identify the issue.)

I hope this helps.

My computer won't start in safemode or in any other mode


test all leads that attach to your hard drive including electrical extensions SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them they could be faulty

laptop or desktop computer??
test your psu power supply unit if the psu units fan is not working the psu is faulty
make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty or just replace them they could be faulty ?

even something as small as an electrical extension or a faulty fan lead can cause this problem computer needs all of the data and power to travel through every working device and to have an end for a computer to be able work properly


a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive check all electrical extensions make sure they are securely seated even the cd/dvd drives need to have current go through make sure these devices are working


also check your computer ram and cmos battery to make sure they are securely seated and the battery has plenty of charge Cmos battery on some motherboards are soldered in
hope this helps you

Computer will not turn on at all. Dell Dimension 5100 desktop


I would unplug the power supply from the motherboard, wait a little while and then plug it back in.
Try to power everything back up and it should come up.

I am assuming you are getting a light on the motherboard that indicates power is being supplied?

Non response from tower


If you're hoping for a bargain out of it, it depends how much your time is worth. Given that the PSU was dead, and other components are showing problems, one or more of them were probably affected. Could be the fan is spinning slow due to damage, and the motherboard is refusing to fully init because of the fan... but I doubt it. The CPU may or may not be okay, but the value is likely to be low. The RAM is probably okay, but again, value is likely to be low. Your best bet would be if you had a second similar computer, to try interchanging parts and see which are damaged/working. In general, though, the system probably is of very low value when working. It looks like it may be model T3624; if so, a model recently went on eBay for $140 (including shipping), in working condition and with 512mb RAM. (item 190155139483) Personally, I would try to sell it as-is for $75, with the dead PSU, or the amount you paid for it (if applicable). Depending what the PSU cost you, you could also add that to the price and ask for that, with the working PSU. At the end of the day, the question becomes, how much would it cost to buy this computer (or a similar model) in known working condition? Is the value of your time, or replacement parts, going to exceed that?
