Asus P4T-M version 1.05 Not Posting?

Hi there,
I'm trying to put this very old system together and for some reason it will not post? The System fires up , Cpu and Video fans spin. There is no beeps coming from speaker though? It will not post into bios screen. Only things Attached are vid card, memory, cpu, and one hard drive. I have power to the main plug but not to the p4 plug. Even though asus recommends the four pin power to be hooked up, I do not think this is the problem and the power supply doesn't have the P4 power cable and plug coming from it. The vid card works in another system. Unfortunately I can not attest to the workings of the memory, I got given 2 x Asus P4T-M Mobos, one with 2xsticks of 128mb (each Rimm) and One with a single 128mb stick plus the C-Rimm sticks needed to fill the unused slots. One thing I did find curiuos was one of the mobos prefers it's "Clear cmos" settings on 2-3, (According to the manual 2-3 = Clear and 1-2 = default normal operation) otherwise it never wants to shutdown and restarts when I release the power button after 5 secs?
Any Ideas? many thanx in advance. Regards Ed. (21st March.2008).

Hi ed, that 4-Pin ATX_12 connector near the CPU is for powering the CPU. Suggest you change PSU's. Though I'd agree there are some boards that have the 4-Pin connector & it's not used. Those boards usually have a 24 pin main connector & lower voltage CPU's Please check here at Asus web site for P4T-M.

I'm sure your P4T-M will boot after connecting the ATXPWR, ATX12V. As you noted, it would be nice if you could test the memory. When you get display you can test your memory for free by downloading a mem test program at. http://www.memtest.org/

Enjoy the weekend Ed.

    Hello again ed, your cmos is not abnormal. I have many manuals & your is one of em. Play it safe & move the jumper to pins 2&3 leave it there for 15 seconds or so. Than re-set back to pins 1&2.

    Remove the battery as well & check it's voltage.

    Guess I'm loosing my mind, I posted the incorrect Asus site for your boards. Try this link;

ASUS p4 T.E


have you tried a different monitor? A different slot on your motherboard for the video driver? If you look at the motherboard manual, you will find a jumper that will reset your CMOS. However ,I doubtful this will solve it. Do you get a beep at first when you power on the computer?

Power shutting down


check your power-save settings they could be turning the computer off. it could also be a bad chipset that is getting shorted or a bad fan that is causing the pc to overheat and turn off. hope this helps.

P5NT won't boot


Have you tried clearing the CMOS by removing the battery with PSU off and then shorting the 'reset cmos" (or similar) pins on mobo?

Also found this on the ASUS web site under the specs for the P5NT WS board...

01.gif ASUS CrashFree BIOS 2
The CrashFree BIOS2 feature now includes the BIOS auto-recovery function in a support DVD. Users can reboot their system through the support DVD when a bootable disk is not available, and go through the simple BIOS auto-recovery process. ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM.

Have you tried this?

4 seconds long beep


I think that either you have a bad power supply or it is not connected properly. I suppose it could also not be supplying enough power.

Try disconnecting all of the connections to the Motherboard and reconnecting them. Make sure they seat properly. Try a new power supply. You can get a good one from Newegg.com

Motherboard won't post.


I looked up your P5S800-VM motherboard on the Asus site and it doesn?t list the Pentium D915 ?Presler? dual core processor on its list of supported CPSs. Here is the link to show to your sales rep: http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us&model=P5S800-VM
