ASUS F1A55-M LX3 mobo, ATI Radeon HD4650 PCI-E Video Card no response
This mobo came as a part of an Asus workstation. It boots to onboard video fine, but when I plug in the ATI Radeon HD 4650 it does not respond. I did change the BIOS to make sure it was on AUTO select. Then when that didn't happen I set it to use PCI/PCI-E as primary. Neither made any difference. The card works on another motherboard so I know the card is good. Could the slot be bad? Are there any hardware diagnostics I can check this?

Not even seeing BIOS so it's not going to boot to a CD. That seems an irrelevant route.
I did go into the BIOS and set it to use PCI/PCI-E, and I stated that in the original details of the question above. It made no difference.

Apologies. Reading too fast.
But what do you mean by "Not even seeing BIOS so it's not going to boot to a CD."

even if it boots to a CD i would never know because there is no video coming to the monitor at any point.
Do you mean nothing is appearing on the screen now when you attempt to boot?
If so then reset the BIOS on the motherboard. There are usually jumpers there that take it back to default.

Yes I do mean that. And already tried that with no change at all.

Only onboard video works still
Hmm. I suspect that the problem is the card. I'd try a Nvidia card in the slot rather than another AMD card.
I've got a Gigabyte board where an AMD card just won't work while the Nvidia is fine. In this case the board is PCI Express 2 while the AMD card required PCI Express 2.1 I can't remember if the BIOS showed up on booting or not but much swearing occurred in that episode.
Now the specs for your system look like PCI Express 2 for both motherboard and card but it is possible that the card requires 2.1 But to be sure I'd try another card and I'd recommend a Nvidia for testing.

The card was previously in a Dell Optiplex 740 and worked perfect. Not pci 2.1. Will try nvidia card and report back

that's a very interesting point. i will try a different power supply although there is only a motherboard, hard drive and dvd attached.... that shouldn't max out any power supply.... right??
ASKER
good sleuthing
did you calculate what you needed? and how much was that?
ASKER
instead of doing the math, i swapped power supplies out and voila. problem solved. could it have been something besides that?
no - but you still don't know how much you need - so the problem can come back
ASKER
well i added a 500w instead of 350w and only have a HD, DVD, motherboard, PCI-E video card... if I need more than 500w that'd be surprising! thanks so much for your help.
according to that page in fact, it says I only need 214w.... why would my 350 not work? Does it maybe not actually put out 350?

That's total output, more than likely you were just maxing out the 12 volt line.

that is one of the reasons - others are :
- a dying PS
-bad capacitors
-PS aging (delivers up to 20% less than new
the 55W of the video card does not leave 300 W for the rest - and maybe you hook some usb devices on it as well ?

Any other options in the BIOS for setting the video besides AUTO.
A look at a manual indicates that there may be options to force the graphics slot to be used.
Note that I can't identify which version of the motherboard you have so the manual I've used may not be correct but you should be able to download the correct one from Asus.
