Question about ASUS P5L-MX Motherboard

1 Answer

P5L-MX fails to boot.

Alright so this computer has been one problem after another. I got a desktop a while back, 512mb ddr2, winxp professional, I bought it second hand, though it DID work. The computer now wont turn on. at first the computer was stuck in an infinite boot loop due to a registry failure when upgrading to service pack 3. The power supply could be the issue but i doubt it as it was working perfectly fine. All the power connections are snug and in place along with all ide and other various cables. Ive changed the cr2032 battery but still nothing. Can someone help me please, i dont have the money to go out and buy another computer. also the computer will boot fine for about 5-10 seconds when its been off for a while, then it abruptly stops. Somethimes i can make it to the bios menu but as soon as i exit (if it lets me even stay in) it shuts off.

If the motherboard is powering down at random intervals after powering on, that might be a hardware problem that's non-recoverable, like a failing capacitor. The only other thing to check is if anything is electrically shorting the motherboard - does any wire in contact with the board have a split in the insulation, is there a fallen screw, etc? Check behind it, too, and make sure it can't be shorting against the case.

The only other thing you can try is to reset the BIOS. Check the motherboard manual for the specifics. It involves unplugging the system, removing the CR2032 battery, and moving a jumper for a few seconds. That will factory reset all settings and possibly help if your issue is BIOS-related.

You could be onto something with the power supply - especially if it's one of the rails that powers the motherboard that's acting up. Cross-test your motherboard with another power supply to be sure. If you can't bring a power supply to you, take the motherboard to a computer and just stand your motherboard on the floor and stretch the connectors you need from the other computer. (This is less invasive than ripping out the power supply if the other computer isn't yours)

If you notice the motherboard powering down even on another power supply, after a full reset, I think it's toast. :(

SOURCE: System doesn't boot up when 9600GT 512mb is attached

Can't you see the card is faulty.

You even went to a computer shop and it did not start, ask a report from computer shop and ask money back from original seller by sending them a copy of the shop report.

A device of this kind may have gone faulty at any time, the original seller is wrong, and sold you a faulty item.

Write him and ask a full refund.

Buy a new card in the meanwhile, this is just a piece of scrap.

SOURCE: BootBlock BIOS v1.0 BIOS ROM checksum error

Kevin, when you do get this going it is going to be a beast.Nice choices on the hardware. It appears that you are getting text in the bios menu and that is a real good sign. One bit of text you typed might be a clue." You typed Detecting floppy drive A media . . .
Drive A error. System halt" And you said that you had no Floppy. On the first screen were you see your time etc there will be something that says halt on all errors. Change that to halt on keyboard errors only. The wording may be different but you get the gist right?You don't want the bios seeing no floppy and halting on that.I hope this helps you and don't get discouraged. There is usually a simple answer.

SOURCE: computer powers on but then turns off after a few seconds

I know this is a late response but someone might have this similar issue which is generally caused by a faulty power switch on the case of the computer. The switch is stuck in the pressed or active position so when you power the computer the switch still being depressed or faulty turns the computer right back off again and you're stuck in this loop. The best way to identify if this is the issue is to remove the power shunt from the jumper then use a screw driver to jump the power connections that would turn the computer on... if it stays on the switch or entire case needs to be replaced whichever is easier

SOURCE: ASUS p5vdc-MX motherboard won't boot

The light is probably the power light which is ok, but from past experience it sounds like the board is dead for one reason or other. Is it still under warranty? If it is take it back to where you got it, with the purchase docket if you have it and talk to them about what you have tested and ask for a replacement. If it is out of warranty, try ebay or use to search for the same motherboard if you want to rebuild the system without having to reload windows.

P5l mx audio driver win xp 32 bit?


Go to: Asus Support

Type P5L-MX in the search box in the upper left and click "Search Info".

You will need to verify the P5L-MX and click on the link for it. (This is because there is also a P5L-MX/IPAT motherboard.)

When you click on the P5L-MX link you will then need to select your operating system. Select WinXP from the dropdown menu.

Available downloads will then be listed. Click on AUDIO to see the available drivers.

I am using this ASUS (asus M2N-MX nvidia mcp61p chipset

According to the manufacturer's web-site:

this motherboard has 4 x DIMM sockets,
supporting a maximum of 4 GB
of DDR2 800/667/533/ Non-ECC, Un-buffered Memory

and supports Dual Channel memory architecture.

So, add one 512MB DDR2 533 Mhz RAM into one of the slots,
being sure to leave *ONE* *EMPTY* slot between the two sticks,
in order to enable the high-performance "dual-channel" option.

Try your computer -- it should feel faster.

If you still think that need more RAM, buy two 512MB (or two 1024MB) DDR2 533 Mhz RAM, putting the 2 sticks into the two empty slots.

Do I need to buy 2 DDR2 Ram for my ASUS P5VDC-MX Motherboard?

with rams, if the memory it has is higher than that of your cpu, the pc will not boot up or if it is too low compared to your cpu again.

thus, you say it has got two slots right, remove both of the 512's and insert the 1gig only, run your computer, i am sure it will boot up nicely. switch it off. put one 512, if it does not boot then you should know that your ram has an excess of memory that your cpu could not apprehend to.

post a coment if this does not work.

Asus p5 vdc-x motherboard not recognizing ddr2

Ok i am just guessing here

maybe your motherboard does not support

ddr2 rams and hence it wont boot up as it does not detect any ram in the slots......

try to boot with one old and one new ram (ddr and ddr2) and post the result

are you sure whether the ddr2 ram is supported?

Having a problen installing 1gb ram. unit is 1gb ddr2 dimm 533mhz. computer turns on, shows that it has updated the memory, but does not boot


if the computer states that the memory has been recognised. but fails to boot. it may not be compatable memory for your CPU/Processor. Or system bus. check your previous memory stick, to ensure it,s the same running speed 533mhz. Failing this if your computer does not support this.
check the manufacturers website, to see further details:- Maximum supported memory/Speed et,c.
Systems bios date, and whether an update is available. your only other alternative is to install 2 x 512mb sticks of Ram.

I use a P5L-MX motherboard. I took my computer into the shop for a cleanup and reinstall vista due to a trojan virus being apparent. When I got it back, I had no sound at all. I had 5.1 surround before,...

If the sound drivers are alright, may be you have disabled either front panel/ back panel audio through a jumper on your mobo. Change it plug towards front / back panel & check again. Its also possible that the speakers are not working.
