Can you test the card in some other system, a bit more modern one perhaps?
Because it could also be the mainboard lacking to supply enough juice on the AGP port. 440LX is first gen AGP, maybe the mainboards' design wasn't calculated for the more power hungry cards.

Which mainboard exactly are we talking about?

Updated observation
3d mark 99 does run but only for 2 seconds into the graphical test then the system freezes.
Could it be a heat issue?

My guess would be a power issue. Most likely from the mainboard. But again, you need to rule stuff out. I'm afraid you'll have to start swapping parts.

has all kinds of stuff

No, but it can be power issue depending on the board model

I am currently getting to my wits end
My options are
1. Recap the motherboard
2. Install Dell Nivdia TNT2 drivers cause this does kind of looks like an OEM product
3.Test using Win Xp.
Earlier i thought i could just put in a new(old) AGP GPU in my motherboard .

Pls tell me what to do .

Back in the day (2001) I had an ATC-6130 and I wanted to upgrade to cheap TNT2 M64. All 3d games went frozen after couple of seconds. Computer service diagnose that TNT2 use too much power from AGP port for this motherboard. Finaly I had bought Geforce 2 MX 200 and there was no issue with hanging.

ATX 1998 build: IBM 6x86MX-PR266@208MHz on Tekram P5MVP-A4, 128MB SDRAM, Ati Rage Pro Turbo AGP 2X 8 MB SGRAM, Yamaha YMF719e, Adaptec 1200A IDE 100, Windows 95b

I just found out that the TNT2 uses an 3.3 v + 1.5V rail while the ATC 6130 only supports 3.3V. Thanks though.

let us know 😀 its a nice system from the specs, and Nvidia Riva TNT 2 M64 32 mb will give great late 90's performance for 3d games . Might be a drive problem though, there are so many drivers and versions for any given card

no it doesnt. Its perfectly compatible with AGP x2 on your board. The problem is your board having early bad implementation of AGP power delivery

answer might be same as for Re: GA-5AA rev3.2 experience - bios and gpu compatibility?

that is :

in case you are using ATX psu you would need to solder thick wire between ATX connector 3.3V source and AGP 3.3V pins.
in case you are using AT psu you would have to buy one of those $5-10 with shipping ebay "300W 20A Step down Converter" modules (https://www.youtube.com/watch?v=JQtkF3qZd3o https://www.youtube.com/watch?v=R3s_g25Gw68) and wire it to get power from 12V and feed AGP. Its Chinese 300W, but should be enough for 25W 3.3V load

Thanks but this is beyond my practical experience, theoretically i may be able to it but i don't get much time to pursue such project. I might need exact guidelines.
Besides i was going to order a Geforce2 MX400 AGP from Etsy and the low power requirement should do the job.

What if you underclock that M64 to the lowest stable or possible setting?

Use some old version of RivaTuner or PowerStrip.

has all kinds of stuff

Im afraid you will have to lower yourself to the printed media for that, starting with those plasma-online links.
