ATI 9250/Pentium 266 won't start

March 7, 2009 at 13:21:03
Specs: Windows ME, P266/192
I was received a Radeon 9250 256MB video card for free. My 2 newer comps don't use PCI slots so I'm trying to put it in a Pentium 266mhz.

I uninstalled old video drivers, pulled out 4MB Matrox card, plugged in 9250 and turned on the power. But nothing happened. It doesn't even make the usual start up sounds (beep, floppy drive test, hard drive loading). When I put in the old Matrox, of course everything returns to normal.

One of two things?

1. Card ain't no good.
2. You don't have enough processor to run it. The system requirements I could find say minimum is a PIII 450 cpu or better.

Is the Matrox card AGP? What kind of motherboards don't have any PCI slots?

"My 2 newer comps don't use PCI slots"

Not sure what you mean by that...there are very few PCs that don't have PCI slots.

"so I'm trying to put it in a Pentium 266mhz"

Are you sure the card is good? Did you try it in other PCI slots? It could be your board only supports an older PCI version or your PSU is weak.

What happened when you put the old card back in?

On the box, the slowest processor listed is the AMD K6 processor. Isn't that AMD's Pentium-class processor?


The old Matrox card was also PCI.


My other 2 PCs use AGP and PCI Express for the video cards. They do have PCI slots--BUT they don't seem to work well with PCI video cards. The screen goes blank after Windows finishes loading.

The cardbus connector looks like the Universal 32-bit PCI Card in the Wiki pic. The PSU is 11 yrs old, but it is 300 Watts--more than stated minimum of 250.


It starts up normally when I put the Matrox back in.

A screen going blank after windows loads usually means a driver problem or configuration--horizontal frequency or screen area--setting that's not compatible with the monitor. It doesn't indicate a problem with the card or slot. Booting to safe mode and choosing to keep the safe mode video setting will allow it to boot to normal mode next time. The drivers can then be reinstalled or configuration changed.

Of course that's not why the radeon isn't working in the P-II. Have you seen the card working in another PC?

Check in cmos/bios setup for a VGA IRQ. Toggle whatever that current setting is. Also try moving the card to another slot.

Otherwise, as already mentioned, the card is probably bad.
