ATI GPU's make pc not post

so I work at a retail store and we sell both Nvidia/ ATI cards and so far we've had a few ATI cards just not post in machines. Being either custom machines or Dells, HP's whatever. Put in an Nvidia card and they post just fine

So far it has only been the 4000 and 5000 series, never a high end GPU, but usually around the 200 dollar parts of both series.

Just curious if anyone else is having these issues or if Kyle knows anything about it or could talk to AMD.

Also we have PC parts here so we always try a new PSU in all the machines and still no go, and again the PC won't POST! So it's not a driver issue or anything, its in the hardware, and then we put in just a random Nvidia card in and it works just fine.

This is just pissing me off mostly because I like ATI, but my manager hates them a lot and now he's starting to prove me wrong. He hates them because we have a game center (about 30 PC's hooked up) and he used to do ATI in the past and had nothing but issues, switched over to Nvidia years ago and had minimal to no issues ever since. Ever since the ATI 4k series came out I convinced him to carry ATI and now we're having issues.

Any suggestions/ideas would help thanks. Also for the cards that don't work we try them in another machine and they will work just fine in some machines (most, but some boards for whatever reason hate them)and sometimes we just RMA the card, so any ideas? Because it's starting to become a hassle
 
I have the same problem the other way around. I tried putting a gtx 260 in a pc that was running a 5850, and no post. Fan runs, no signal at all....weird and annoying.
 
i assume you tried diff PCIe ports?

Connected any power connectors to the cards?

reset the CMOS?

what kind of power supplies? no name, or good solid ones...

i know you said dell and HP, but any other mobos you can give names of?

is this happening with EVERY 4/5 series ATI card if so something else is wrong, not the cards.
 
yes different PCIE ports,
yes power is plugged in,
yes reset the cmos,
PSU is a 500w forget manufacturer its our test PSU that we use around the shop, it powers everything. Again put in an Nvidia card with that PSU and it works. But also we've had it happen to Kingwin PSU's, Corsair, and Silverstone that I know of.

My friend is actually experiencing the issue right now, he has a Gigabyte SLI board and sorry but can't give you model number but he bought an ATI 5770 and wouldn't post, put in old nvidia GPU and works just fine. He is buying a new board though. I'll ask him for a model number later.

No its still a rare thing happening, we get it say once every month and figure we build 3 PC's a day and pull in 6 machines a day for repairs with random errors so ya its fairly rare, but still getting on my managers nerves and then I have to listen to his shit.

When you say it doesn't POST, have you checked to verify it isn't just a case of no monitor signal? If you are connecting via DVI, try the analog. If you get a signal, you need to change the DVI options from CCC (reduce frequency/alternate operation mode). I had an X1900XT with this problem and my current GTX260 is the same (it depends on the monitor and the DVI output from the card). They worked via DVI just fine after changing settings, although no signal until Windows loads.

I've experienced this before. It is usually a monitor EDID issue rather than a problem with the cards themselves or any type of video card/motherboard compatibility issue. The Viewsonic VP201s I have on my work bench will not work with the most modern NVIDIA cards or any AMD/ATI hardware dating back to the X1800XT.
 
I read something somewhere a couple months ago that some Dell/HP computers needed different bios for different videocard brands ATi / Nvidia.

I can't seem to find that article but will post if I find it. But Dan_D is probably right.
 
When we were diagnosing we unplug everything so it's not even plugged into a monitor. All we are looking for is the POST beep! Nothing with drivers or anything else this has to be hardware within the case itself. I'm guessing that it's a certain chipset with a certain bios that for whatever reason just doesn't like ATI cards.

So realize when I say no POST, there is no beep, thus not going to the bios. The PC was not plugged into a monitor or anything else, no keyboard or mouse, just a power plug. We just wanted to hear the POST beep which we got when we switched it to an Nvidia card.

Just making sure. I've seen the whole EDID thing with monitors and ATI/AMD cards for several years now.
 
I'm thinking the system boards are not up to the PCIe specs... Your best bet if you are a retailer would be to contact Dell or HP for each model it happens on and have them replicate it and diagnose it. It's not an ATi problem.

They'll conform to PCI -Express specifications, the problem usually lies with the BIOS in situations like this.
 
You've got to understand that companies like Dell and HP do not do extensive graphic card testing and validation in their systems. Such testing costs considerable time and money. Retail systems have a very short production life and very few people upgrade their graphics cards.
