Solved PC won't boot with ATI x1600 video card installed.

October 19, 2015 at 04:04:36
Specs: Windows Vista, Pentium 4/ PC2700
I have a Dell Dimension 4400 and I am trying to upgrade the video card.

The support documentation says the AGP bus protocols for the motherboard are 4x/2x modes at 1.5V. And the slot is a 1.5V keyed slot.

The video card I am trying to install is an ATI Radeon x1600 Pro 512MB DDR2 AGP 8x/4x card. It is keyed to fit a 1.5V slot.

The machine originally had a Geforce2 card installed in its AGP slot, which it boots fine with. That card was keyed for 1.5V and 3.3V.

When I try to boot with the Radeon card installed in the slot (with floppy power connected to card), I get nothing on the monitor. The fan on the GPU spins up right away (although it is kind of loud, probably wearing out) and the LED on the monitor is orange.

I thought it might be a power supply issue, so I swapped the supply with another. It says it is 300W, but only puts out 14A on the 12V rail which is no better than the 250W dell power supply that was installed as it turns out. But it was in a machine powering an x1300 Radeon card. The swap didn't help though. At that point I got smart and just unplugged the drives, but it still would not display anything.

I am thinking now that this card is just not compatible or is bad. Anyone have any experience with this?

Those cards powered from the floppy connector aren't all that power-hungry but then you are dealing with some wimpy power supplies so it's hard to say for sure if it's the PSU or a bad card. However since the previous card worked OK with that same power connection and the new one doesn't I'd tend to suspect the card.

Since it's used were you told it was definitely working previously?

Did the new video card also have a place on the card where it needed external power cord plugged into it?If so it needs more another regular power connected coming from power supply.

Yea, I used the power adapter that came with the x1300 card on the x1600 card. It is just a splitter that connects to one of the 4 pin molex connectors. It provides another 4 pin molex connector (so you haven't lost anything) and an additional smaller 4-pin connector for the graphics card. It's the same kind of power connector as used with a floppy drive. I didn't have a better name for it, so I just wrote it up as "(with floppy power connected to card)".

I think I'll try and find another motherboard that I can plug this card into and see what happens.

Anyone know if the fans are replaceable on these or how to go about selecting one?

Well I found another machine to install the AGP card into.

This other PC has a Gigabyte "GA-7VT600 1394" motherboard. The AGP slot is keyed for 1.5V and the manual says that it "supports 8X/4X/2X mode(1.5V) & AGP 3.0 Compliant".

It boots with the Geforce2 AGP card installed, but not with the Radeon card. So, nothing new there.

Unfortunately, the power supply in this PC is even less powerful. The 12V rail can only supply 12A. I unplugged all the drives. In this condition, should 12A be enough to power it?

I measured the voltage at the power connector. Unloaded, the voltage at the floppy connector is 5.32V and 12.97V. And when connected to the AGP card, the voltage at the pins on the solder side of the board are 4.96V and 11.07V.

I did not measure what it was in the other PC's which had 12V/14A rails.

What do you think, bad card or underpowered?

Since it's not working in two different machines, I'd say it's a bad card. I doubt that the power supplies are at fault here. Video cards use next to nothing in text mode.

Yea, I got it on Ebay, it came in the original box/packaging & was supposedly tested. But who knows how or when. Maybe they figured the fan was spinning so it must be good or the last time so many years? ago it worked.

"I got it on Ebay"

Well, hopefully you didn't pay more than $10....

Ahem $50, cough. Overpriced I know. I paid for the original box. I figured it would be in better condition lol. I'm trying to get refunded... not going well though.

@#4 I have since upgraded the power supply to 520W. It still doesn't work.
