Specs: Windows XP, hpa1203w
I recently bought a new video card for my computer that is a little over 5 years old. When I was installing the video card the instructions first made me disable my current video card, and restart my computer. I restarted my computer and now it is stuck on a blue Hp Invent Screen that says <esc> Boot <F1> Setup <F10> System Restore. My keyboard and mouse are not working and I cannot get past this screen. Does anyone have any idea on what to do? I am really stuck.

If this computer is a HP Pavilion a1203w Desktop PC, and if you have installed a Diamond multimedia Stealth 9250 AGP graphics card......

the short answer is...

unplug your computer and remove the Diamond multimedia Stealth 9250 AGP graphics card !!

You probably CANNOT use an AGP Radeon 9250 video chipset graphics card with the mboard on the HP Pavilion a1203w !!
Trying to do so is likely to DAMAGE the mboard's AGP slot circuits and possibly other mboard circuits , and possibly the graphics card !

The details.

The Radeon 9250 video chipset supports 2X / 4X / 8X AGP.
2X AGP uses 3.3v; 4X / 8X AGP uses 1.5v (some 8X AGP uses 0.8v ).
The AGP slot on this mboard can only support 4X / 8X AGP - 1.5v AGP cards.

On SOME mboards that support only 4X / 8X AGP - 1.5v AGP cards - installing a card with a video chipset that supports 2X, or 2X / 4X, or 2X / 4X / 8X AGP will DAMAGE the mboard's AGP slot circuits and possibly other mboard circuits , and possibly the graphics card !
Your strange symptoms probably indicate your mboard is one of those that cards with video chipsets that support 2X AGP cannot be used on !
If you are fortunate, the video card you were using before will still work; if not,
- if the previous card is AGP, just the AGP circuits may have been damaged, and in that case, a PCI video card will work.
- if other mboard circuits have been damaged, your mboard may no longer work with an AGP or a PCI video card.

You need to use an AGP card with a video chipset that does NOT support AGP 2X, or use a PCI video card. (e.g. you can probably still find a PCI Radeon 9250 card.)

The specs in ads for video cards may mention only the max AGP they support. Cards with video chipsets rated as supporting 8X AGP always also support 4X AGP - some older 8X capable video chipsets support 2X AGP as well. Cards with video chipsets rated as supporting 4X AGP often also support 2X AGP, but a few support only 4X AGP.
(Older video chipset = it was first released earlier - a new video card may have an older video chipset.)

You may need to go to the manufacturer of the video chipset's web site to find out whether the chipset supports 2X AGP or not.

E.g. Many Radeon video chipsets that were first released after the 9250 chipset DO NOT support 2X AGP and can be used with an AGP slot that supports only 1.5v 4X / 8X AGP video chipset cards.

See this - it shows you which Radeon video chipsets DO, and DO NOT support AGP 2X:

That document was Last Updated 18/02/2009. ALL AGP Radeon video chipsets first released AFTER that date probably DO NOT support AGP 2X.

HP Pavilion a1203w Desktop PC Product Specifications

Motherboard Specifications, K8S-LA (Salmon)

Graphics None (no video built into the mboard)

Graphics connector (AGP) 1 AGP 8x

Note the diagram of the mboard.
On the AGP slot it says 1.5v AGP slot only.

I found by searching with Pavilion a1203w here:

that your original power supply has either a 250 or 300 watt capacity.

Power Supply
5187-1098 Power supply - 250-watt, regulated (Zinfandel)
5188-0129 Power supply - 300 watt (Merlot B, Reg. with latch)

If you get an AGP card with a video chipset that was first released more recently, you MAY need to get a power supply with more capacity, especially if the one you have has a 250 watt capacity, and the card may have a socket or connector on it that you must connect an additional power connector from the power supply to, often the small molex power connector the same as one you normally connect to a floppy drive.

Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.

If you need to get a PS with more capacity, you can usually replace it with any decent standard sized standard ATX PS.

Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.

Don't buy an el-cheapo PS.

I made a mistake clicking the right video card I have a Diamond Stealth S120 256MB Graphics Accelerator Card. The card requires 250 Watt. When I was purchasing the card the employees at the store looked up my computer and found the appropriate card. I'm not sure about all the technology language you are using as I am just a computer user, is this card any better than the first one I listed??

I'm assuming that you have NOTchanged anything else that you haven't mentioned, e.g. the ram you have installed in the mboard.

"I have a Diamond Stealth S120 256MB Graphics Accelerator Card."

It uses the Radeon 9250 video chipset.


Brand - 9250 (= Radeon 9250)

System Requirements

System bus - AGP 3.0 compliant (4X / 8X)

Power supply - minimum 250 watts

Support page for it:


The one on the right is the PCI version. You can use that, no problem.

If you don't want a PCI card, you're going to have to get an AGP card with a video chipset that does NOT support 2X AGP. The info in response #1 tells you which Radeon video chipsets are appropriate.

All of what I said in response #1 applies.

The specs in the pdf and on the Diamond site don't mention 2X AGP, but I know for certain the Radeon 9250 video chipset supports 2X AGP as well as 4X / 8X AGP.
I have a PowerColor card with the 9250 chipset on it. I got it so I could have the option of better video with older mboards that support only 2X AGP, or only 2X / 4X AGP.
I know for certain it works fine on SOME mboards that support only 4X AGP or only 4X / 8X AGP, but it does NOT work fine on some others of them !
The mboard manuals for retail mboards that CAN be damaged by installing a 2X AGP capable card have a WARNING about that in the manual, but, of course, there is no manual like that for a retail mboard for most mboards used in brand name computers.

You probably can't use that card with your mboard.
