Question about PC Chips P21G (881038000916) Motherboard

1 Answer

MB ports no longer working

My package is -
I have a PC Chips P21G LGA775 Motherboard, P4 -630 (3.0 GHZ) Processor with 3GHZ of DDR1 memory.
I purchased the motherboard in November of 2005 and have had no problems that i could not figure out until today. I have been using the audio jacks for my headphones ever since. Just purchsed a new set of headphones with a USB connection and plugged it in this morning. It seemed to recognize and set it self up for the new phones with no problem at all. 1 hour later, I'm working in one of my apps while on TS and the screen freezes. I reboot and 30 minutes later it freezes again. I reboot and everything cycles on just fine except that the screen remains black and the optical mouse, keyboard and other ports no longer seem to function.
Hmm, I take my rig apart and give it a thorough dusting. I examine the MB for short circuits put it all together again, test the mouse and monitor in another PC and the problem still occurs.

The MB is only 3 years old. I have maintained it nicely with a few upgrades here and there and am just curious as to wether or not the MB has just run its course? Shouldn't a MB last longer than 3 years? I have plans to upgrade to a modern PC in the spring but was hoping to pass this one down to my kids...Could it be that the ports are bad? Can they be fixed? Any insight would be much appreciated. Thanks guys.

P.S. I have used many different phones over the years ranging from expensive to cheap and this USB driven one was purchased from Radio Shack. I can't imagine that it would have anything to do with the problem but I obviously am no expert on these matters.

    After consideration of what you stated and more time to evaluate the boot up procedure of the pc, I have some more info to help clarify and another question.

    First after you mentioned the processor, I listened better for the sound that occurs when data is being processed during bootup and discovered that there was no such sound. I also have an external drive that I access via the usb ports. When I plug the external drive into the port it comes on automatically as it should and then after a moment it shuts itself down.

    1)Could it be that the usb ports are working since the external drive recognizes them and then shuts itself off when it can not find a data exchange source?

    The rig powers up the case fan and other hardware devices such as disk drives and additional case fans and even the monitor that need no software to run which tells me that the MB is still functioning as it should, as a highway of circuitry, if you will, but while no other bootup actions are occurring such as Sytem bios, video signal, mouse or keyboard detection and even the little "happy beep" that occurs when your processor kicks in, that more than likely the Processor has gone bad.

    2) Does it make sense to you, given the info stated, that the MB would still be okay and the processor has just run it's course?

    Another thing that I failed to mention that may be critical. I normally maintain my pc with great care but recently life issues caused me to slack in the routine dusting of my interior case, particlularly the processors cooling fan. As I cleaned it yesterday I was furious at myself for seeing the accumalated dust in the coils. I'm sure but must inquire.....Could that have shortened the life of my poor little processor that could? Thanks again.

    BTW, Thank you for your speedy response.

Does the probem persist even if you disconnect the USB headphone? If it does, then it points to problems somewhere else in your system. If it does not, then it's very likely that the USB headphone itself is the cause.

USB headphones aren't like headphones that you just plug into your soundcard. USB headphones has their own "soundcard" that's built into the device itself. Thus USB headphones will work regardless of whether or not you had another soundcard installed. This is usually USB headphone's benefit, not being dependent on other soundcards and having its own discreet settings.

In your case though, it's also likely that the USB headphone's driver itself is causing conflicts with other parts of the system. If this is the case, it would explain why your system is freezing.

As far as the longevity of the motherboard itself... these days computer chips are producing so much heat, it's very likely that motherboards/CPU/memorhy do not last longer than 3~5 years. The parts simply break down much faster than they used to.

    The lack of the "happy beep" usually points towards one of the three components, RAM, CPU or the motherboard. It's hard to be conclusive to which one of the three problems it might be. Do you have another PC with the same type of RAM as used in this one? Swapping RAM would be the easiest, and the cheapest of the three to test. If that is not the problem, then CPU swapping & motherboard would be the next items on the list.

    Before you do that though, have you tried starting up the computer without any USB devices plugged in? If that allows the computer to boot up, it's very possible that the USB port itself is broken. I've seen computers where USB devices would prevent start-up/shut down of the computer (in fact, I just ran into this issue a few weeks ago with an external USB hard drive that prevented my computer from shutting down, because the hard drive itself won't shut down).

    Computer parts do accumulate dust at an alarming rate. Although, I only clean my own computer about once a year, at most. A huge amount of dust could prevent proper heat ventilation from the CPU, but in most cases I've seen, it's not sensitive enough to cause a huge amount of issue over a year or two. If your CPU was really having problem dissipating heat, you probably would've seen crashes running day to day applications on a regular basis before it completely just gives up.

    Weather & other components in the system could complicate the issue though. The best your computer can do with cooling, is get it to room temperature (provided you're not using liquid cooling or other method than just air cooling). Computers for the most part, are designed with that in mind. However, if you couple a hot running CPU (which may still be running within spec) and a very hot environment, it would shorten the life of the CPU. I had such a problem when my computer couldn't handle dual-video cards in warmer weather, because the heat coming from the video card was simply too much for the case to dissipate quickly. Eventually I removed a video card from the system just for better stability.

Unfortunately, these are old processors and I don't see any available new. lists a couple available as refurbished. You may be better off getting a new computer with either a Intel I3 or current AMD processor.

I wish that I had better news for you.

Hi, I need standard spec info of VGA built on Asus P5GC-MX 1333 whether 64 Mb or 128 Mb. Many thanks & regards, Richard

you can use up to a maximum of 224 mb of your computer's RAM for the onboard video chip to use. You can install a video card with any amount of memory (which would give you a lot better video performance).

Can some one please let me know the name of the motherboard supporting Pentium 4 1.5 Ghz processor as well as Intel Core duo series of processors. Thanks, Ajay

The chips to which you refer are incompatible with respect to the socket used for each as well as the fact that Core duo and Pentium 4 1.5 GHz chips are from separate generations, the latter having been obsolescent since 2003. Therefore, there is no single motherboard that supports both, and the Pentium 4, Socket 478 boards can be obtained from various aftermarket sources.

Here is an example of the kind of board you need for your Pentium 4.
