Hi and thanx for reading.

So here's the story. At first I replaced my ASUS P2B Motherboard with an ASUS P3V4X. Nothing wrong, all running well. A couple of months later I replaced my Pentium II 450 Mhz by a Pentium III 1000 Mhz (both genuine Intel). And at the same time upgraded my RAM from 128 (100Mhz) to 256 (133 Mhz).

After restarting I got a BIOS warning about my voltages. Checked the BIOS and saw the Vcore running at 2.0 with an indication this was in error (by the way it run at 2.0 with my Pentium II flawlessly). Futhermorethe BIOS didn't recognize the Pentium III at 1000 Mhz. In the manuals I've read that the Vcore voltage should be around 1.7 approximately for a Pentium III. It took me some days to figure out, but -this is important- I did quite a few cold starts (in the evening turning the computer off and the next evening restarting)and had no problems with my monitor (this is an Iiyama 15" TFT with USB hub).

So i've got a BIOS update from ASUS to version 1006 Beta 002. I was presently running 1005 version. The 1006 beta version was the only newer I could find. It installed properly and after restarting it recognized my Pentium III at 1000 Mhz and had changes the Vcore to 1.7. And my voltage warnings at start-up where gone. So... I was very proud afcourse....:-)

But now every time I do a cold restart (computer has been off for a day) I get a few beeps and no monitor signal. When I do a reset to start it a second time my monitor does start. When I use the computer and turn it off and directly turn it on again the monitor is also oke.

So it happens only at "a cold start". I have no clue what is causing this. I'm thinking about the Vcore, maybe put it a little higher, but read this could damage the processor.

So if any of you have any clue please respond.

Thanx in advance.

The only "clue" I see scared me when I saw it. http://www.PCGuide.com/ubb/wink.gif

BIOS update and Beta version. In the same sentence. Seems awful risky.

Do you have any conflicts showing in Device Manager,
especially in the USB controller area?

Tjaymadison,

Thx for responding.
No, i have no device errors. Device manager is totally clean. USB no problemo.

I've paid more attention to the beeps I'm getting: 1 long, three short. Found in the Award BIOS Beep Codes: "Video card not found or video card memory bad". I will reinsert the card, maybe it helps.

And last weekend it did do a cold start that directed me to the BIOS indicating that my processor e.g. Mhz speed was adapted. But it still gave me the Pentium III at 1000 Mhz.

Today i had to do the reset trick. And noticed the message "updated ESCD succesfully". So my best clue is that the processor is not correctly recognized by the BIOS, maybe because it's a beta. But then again, every time i hit the reset button it starts -and works- flawlessly....

I'll try putting it on 850 Mhz and see what happens then. I'll also run some hardware tests.

Any other suggestions are appreciated.

This may sound strange but try to slow down the POST, try turning on floppy detect and maybe anything that is optional like a second memory check. It may be POSTing to fast to properly detect everything.

Did you check to see if your new mobo supports VRM 8.4? Converting from socket 370 to the flip-chip is not a slam dunk. Your BIOS update seems to have corrected the voltage setting (1.6-1.65 by my specs) but the PII was lacking a reset pin compared to the PIII and your socket might have a problem with that.

First thing, I would get ahold of ASUS and pelt them with questions about the FC-PGA platform.
