9800 Pro AIW - PC Won't Power UP!

[jsabino]

Just replaced my GeForce4 ti4400 with a brand new 9800 Pro All-In-Wonder. Here are my specs:

Epox 8RDA+
Athlon 2400 (Not Overclocked)
512 Corsair XMS PC2700

I uninstalled the Nvidia drivers, shutdown the box and removed the card. Installed the Radeon and when I hit the power button the PC would seem to power on for a split second and power right off. I figured that there was some issue with the power supply not giving enough juice since now I had to hook it up to the Radeon (I also have 2 cdroms and 3 hard drives in the box). The Power supply was an Antec 300W. I took that out and replaced it with a 400W Antec that I had lying around and after hooking everything back up last night the PC finally powered up and I was able to install the Catalyst software from CD and everything seemed to be working fine.

I wake up this morning and attempt to power on the PC and sure enough, it's doing the same thing where I hit the power button and it powers on for a split second then power right off. This is now with the Antec 400W power supply in the box.

Any ideas on what is going on. I can't imagine that I'm not getting enough juice from a 400W PS. HELP!

Thanks...JS

I fought with this problem all day yesterday...it turned out that my mobo (Epox 8KHA+) refused to work with the AIW, since it worked in every other computer in the house with no problem. I switched my board out to a 8RDA+, and now I'm not having any problems....so if you can, try the card in another computer and see if that works.

The power connected to the video card? Also, try giving the card an extra push, it may be seated improperly.

either something isnt seated properly or one of the power connectors is not completelty snug in a peripheral. Check all connections to make sure they are 100% secure.
