Pentium IV and Aopen AX4T Mobo

[andersgoransson]

I have problems with a Pentium 4 and Aopen AX4T Mobo. 2x 64MB memory was bundled with the CPU.

My system.
P4-1.4
2x64MB Mem
3D Blaster Geforce II MX SDR
Aopen LX45 250W power.

I can´t even get into BIOS !!!!!!!!!
What to do?

Does it power up? Maybe it's not plugged in. Make sure to hit the power button too. Depress it all the way.

 

[fkloster]

What was your problem again? Did you terminate the empty memory slots?

 

[andersgoransson]

It powers up but I got no picture on the monitor. Yes, the memory slots are terminated.
Can I use a ordinary case (aopen) or do I have ´to get another type? There are some more powerconnectors on
the mobo (aopen)

You do have a P4 approved PSU right?

from Intel site

Items supplied with a Pentium 4 Processor-Ready chassis
Four additional holes in the chassis base plate
Four additional standoffs around the processor
Four additional retention mechanism mounting screws
One ATX12V Power Supply (may be purchased separately)
Additional thermal management (Minimum 1 80mm chassis fan with 3 pin main board header)


To adequately power the Pentium 4 Processor an ATX12V compliant power supply should be used. The ATX12V power supply provides increased 12V, 3.3V, and 5Vsb current to the Pentium 4 Processor main board. The ATX12V also provides additional cooling capability. An ATX12V power supply can be easily identified by the addition of an additional new 2x2 pin connector and an optional 1X6 pin connector. The Pentium 4 Processor uses the 12V output from the power supply due to superior power conversion and reduced I2R (Current^2 X resistance) losses as compared to 3.3V or 5V power conversion.

You probably need to buy a P4 power supply.

Anders... so, it powers up? Do you see all the fans running and heard the hard drive going? Do you get the initial *BEEP* at bootup from the internal speaker?

 

[Wingznut]

Ok, so I just unplugged the two extra connectors on the motherboard. (I only have the standard ATX connector plugged in.)

So, the system should boot up (at least) with just the standard ATX connector.

 

[Zach]

Check what your PS can dish out though. I have a standard ATX in front of me (nicer Antec, 230W), it does 14A at 3.3v, 25A at 8v, and 8A at 12v. If his can't pump out as much as yours through that ATX power connecter, it might be the problem. You's is designed for these systems too, so I bet it does have much higher power output ability.

Of course, it could still be a dead CPU or motherboard.. but I think using the wrong PS is something that should be troubleshot first (what tense should that be?).

 

[fkloster]

Pez so you can run your P4 without the auxilliry power & without the 12v?

 

[erub]

maybe the motherboard is grounded? tried putting it together ontop of a static bag outside of the case, just with the cpu, ram and graphics card hooked in, to get into BIOS?

 

[Wingznut]

Yes, right now I'm running at 1.7ghz on only the standard ATX connector. I plan on running a bunch of stability tests and overclocking tests a little later. I'll probably start a new thread with my findings.
