Video Card incompatibility?

Sapphire Radeon hd 5570 video card
August 17, 2010 at 16:31:32
Specs: Windows XP
I've recently purchased a Radeon HD 5570 graphics card. After putting the card into my computer, removing my previous card, I ran into some trouble.

When plugging my monitor cable into the card and turning my computer on, my monitor acts as though it is simply not getting a signal.

So I opened up my computer and checked it once more with the same result. I then put in my old graphics card (with no problems) and installed drivers, thinking the problem was just me doing the basics steps out of order.

So, upon installation of the software, I tried installing and reinstalling the hardware a few more times with the same result.

What do you think? Is it a hardware issue? My PC (a VGC-RB40 model Sony Vaio) is supposedly compatible with this video card.

Did you uninstall all traces of previous ATI entries in add/remove programs first. You didn't say what your previous card was. If it was ATI, you need to remove all traces before you install the new card.

"Radeon HD 5570 "

Not all features of the card are supported by XP, but that would not result in you getting no video. XP can't support DirectX features higher than DirectX 9.x ones - simpler features will be substituted for DirectX 10 and 11 only features.

- ATI Eyefinity technology works with games that support non-standard aspect ratios, which is required for panning across multiple displays. To enable more than two displays, additional panels with native DisplayPort™ connectors, and/or DisplayPort™ compliant active adapters to convert your monitor’s native input to your cards DisplayPort™ or Mini-DisplayPort™ connector(s), are required. ATI Eyefinity technology can support multiple displays using a single enabled ATI Radeon™ graphics card with Windows Vista or Windows 7 operating systems - the number of displays may vary by board design and you should confirm exact specifications with the applicable manufacturer before purchase. Systems using multiple ATI Radeon™ graphics cards can support a maximum of 8 displays (total across all cards in system) with a maximum 6 of those displays being used together in a display group (also known as a single large surface mode).
- Requires application support for ATI Stream technology
- Windows 7 capable system required
- HD Monitor Required

If the HD5570 card has a power socket on it, you must plug in a PCI-E wiring connector from the PS into that socket.

400 Watt or greater power supply recommended

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.

Edit: I got my PC's mixed up.

My old card was, in fact, an Nvidia. Would uninstalling the Nvidia drivers help?

You should get video before Windows starts to load in any case.

It's unlikely NVidia drivers being loaded would result in no video from an ATI video chipset card - they probably would not be loaded when you installed an ATI video chipset card.

You are supposed to un-install previous video drivers and associated software for a card in a slot BEFORE you install a different video card in a slot, in Control Panel - Add Remove Programs - reboot at least once, such that Windows is in a default VGA mode of one sort or another.

DO NOT install drivers for a video adapter when the New Hardware window pops up - CANCEL that - install the software for the video adapter using the proper installation program.

So I uninstalled what all I could find of the nvidia software on my computer and restarted my computer. It immediately found new hardware (which I'm assuming was my old nvidia card which was still in my computer at this point).
So I shut down my computer, swapped out my old card with my new ATI card and was met with an unresponsive monitor; the same problem as before.
I once again installed my old nvidia card (as my computer will not display without it) and attempted to uninstall the "new hardware" it detected and shut down. I once again tried my new ATI card with the same results as before.

I'm assuming my computer is now running on the default VGA settings at the moment, as the video performance is noticeably a step down from even my old graphics card. However, any attempts to boot up the new card at this point are met with the same result; or more accurately, a lack thereof.

Am I missing something? Is my nvidia card still in effect and my default VGA settings aren't? Am I better off just taking it to a shop to get them to try to install it?

What size power supply do you have? Does the HD 5570 require a 6-pin PCIe plug??

I copied and pasted this from a list of my PC's specifications (Sony Vaio VGC-RB40)

Device Type- Power Supply
Voltage Required- AC 110/230 V ( 50/60 Hz )
Power Consumption Operational- 305 Watt
Installed Qty- 1

I also see that my new card requires a 400+ watt power source if I'm not reading this wrong. Looks like I'm buying a new power supply. Thanks for the heads up!

The PS wattage rating you need to be concerned about is max total (DC voltage) OUTPUT. PSs are NOT 100% efficient, so if the PS requires a max of 305 watts of AC power, it's max OUTPUT is less than that,
E.g. 80% of 305 = 244 watts

The rated max total OUTPUT is shown on the label on the PS.

According to info I found on the web,

- your model may have a BESTEC ATX-300 - 12EB3 power supply, max 305 watts output.
BESTEC power supplies have a poor reputation and are known to be a LOT more likely to malfunction than most brands, and a LOT more likely to damage something else, often the mboard, especially when they fail completely. emachine desktop computers use them, and them malfunctioning or failing completely are probably the most frequent thing that causes emachines computers to fail to boot.

- your HD 5570 video card probably does not have a power socket on it

- the BESTEC ATX-300 - 12EB3 has no PCI-E (6 or 8 pin) connector on it's wiring. It has a 24 pin main connector, so a replacement PS must have a 24 pin one.
Most new and fairly recent PSs have a combo main connector that can be used with either a 20 or 24 "pin" socket on the mboard.

- most newer PSs DO have at least one PCI-E 6 pin connector, which would be needed for video card chipsets that require more power than the HD 5770 does.

- see the standard size of a PS (above) - if this Sony model is a small form factor computer, your PS may be smaller than that, and you may need to buy a PS of a smaller size meant for small form factor computers.

As per i know there is some requirement for that card and if you fulfill that then may be it will works for you.

Ok, so I've been browsing through PS's and am looking at this:

They don't give much info in the product description but a commenter noted that it comes with a "20/24-pin ATX" cable.
Would this PS fit the bill?

Thanks again, this has been tremendous help.

That PS should be fine, if your present PS is the standard size.

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.

550 watts will handle almost any video card chipset currently available, if the card has only one video chipset (some have two on one card).

Modular = you can only plug in the cables you need into sockets on the PS, minimizing PS wiring clutter inside the computer case.

PSs that are not modular have all wiring attached inside the PS and are usually cheaper for the same output capacity.
You can tie up the wiring you don't need to use to minimize the wiring clutter inside the case.

It has ....

- 2 PCI-Express Connectors for video cards that have one or two power sockets on them
1 x 6-Pin, 1 x 6+2-Pin

6+2 pin - can be used in a 6 pin or 8 pin power socket - the two extra ones are additional grounds

- Main Connector

It has a 20 pin connector for 20 pin mboard sockets, and in the same wiring bundle, a 4 pin connector that can be attached to the 20 pin connector for 24 pin mboard sockets

- Manufacturer Warranty

Parts - 3 years limited

Labor - 3 years limited

- a good user rating from many people in the newegg ad
