I have the same card, do you have the proper PSU installed?
I'm thinking you may not have improper wattage for that card.
You'll need a 450W or higher for the card to work properly.

Unplug your computer and hit the power button to get rid of the juice.
Open the left panel and look at the power supply. It will show the wattage.
If it's 450W or above, post a comment and I will help you further.
It could be the directx isn't up to date, but still there shouldn't be lines in it.
Try cleaning the connections and make sure they're tightened first.
Turn off the on-board VGA via the BIOS setup. Restart the computer hit DEL upon startup and look through your settings, turn that feature off. As I don't know your motherboard, I can't tell you where to look in your BIOS.
Here are the specs for your card as well, make sure they match your computer.

Trouble with install second video card HD 5450 to emachines t6532


Unclear of your statement. (More like run-on sentence)

Problem heading statement reads,
"trouble with install second video card HD5450 TO eMachines T6532"

Need clarification

The eMachines T6532 Desktop PC uses an MSI MS-7207 motherboard.
Also known as the MSI K8NGM2-L,

http://www.msi.com/product/mb/K8NGM2-FID--IL--L.html

(Click on photo for a better image)


Has one long white PCI Express x16 slot. (Expansion Slot)
Only uses one graphics card at a time, will Not use two.

[Graphics card / Video card. Same/same]

Therefore I surmise you are not referring to adding a Second graphics card, but are referring to;

A) This is the second time you have added a graphics card.

Or,

B) This is the second ATI Radeon HD5450 graphics card.
Had one before. Removed it, and are using a new one.

Or,

C) This is the second time you have added a graphics card.
It is not an ATI Radeon HD5450 like the old one is.

Know this;
1) You can ONLY use the OnBoard (Integrated) graphics,
OR the graphics card.
You CANNOT use both.

When using a graphics card the monitor is plugged into it.
You cannot plug into the onboard graphics of the motherboard, with it installed in the computer.

Said differently;
With the graphics card physically installed in the computer, you cannot just unplug the monitor from the graphics card; and plug it into the OnBoard graphics of the motherboard.

[Also; Computer on, you CANNOT unplug a monitor, and plug it back in.
This = NO ]


2) Driver: Small piece of software that allows the Operating System to communicate with a device.

The device is the graphics card.
The version of Windows operating system was not stated.

Did you install the software from the Installation Disk? (CD/DVD)
Has the drivers on it, and the user interface software.
User interface software for an ATI graphics card, is Catalyst Control Center.

(Just to note; I'm using a Powercolor Radeon HD5450 graphics card, right now.
I'm using dual monitors.

HP 2009M - 20 inch widescreen LCD monitor, and an RCA L26HD31 HDTV as the main monitor. (26 inch HDTV)
They work GREAT! ]

(It is an ATI Radeon HD5450 graphics card just like yours, IF yours has 1GB of graphics memory.

Doesn't matter what graphics card manufacturer, makes that HD5450, it is still an ATI (AMD) design.

Powercolor, VisionTek, Sapphire, Diamond Multimedia, Mickey Mouse, or Goofy. It is still an ATI graphics card )

The ATI Radeon HD5450 graphics card, has to have a MINIMUM power requirement of 350 Watts.
Does your power supply have 350 Watts or more?

If it is the original power supply, the answer is NO.

Back then power supply manufacturers were 'fudging' the true maximum rated wattage.
Why?

Sold more power supplies.

Power supply rated at 250 Watts?
Nope.
More like 60 to 70 percent of that.

Divide 250 by 10.
= 25.
Take that times 6. = 150 Watts (60 percent)
Times 7 = 175 Watts (70 percent)

Would like your opening statements clarified.
Post back in a Comment.

After the most recent HP update, my ATI 4850 now has registry issues. It no longer recognizes my second monitor and the PC only allows for basic video settings. Here is what appears when I run a check...


Yoy can find the sections in the registry with regedit from the 'run' command. That takes experienced users to deal with. Alternatively, use the device manager in 'System' and delete the display device. On re-booting it will go through the found hardware wizard and re-load the drivers.

Gforce 8500 not responding in middle of some games


try a new driver or new gta patch. Really though, you need a new graphics card. the 8500 is a budget low end card. get a Nvidia 9800gtx/ gtx 260 or Ati 4850/4870 to game! Make sure you have a good dual core cpu also.

According to ATI this is a known issue. They refer problems to microsoft about this error as they say it is an o/s issue. Microsoft refers you back to ATI saying it is a thermal issue. I have an ATI card as well & have the same problem. Hopefully the next driver will fix this issue when released. Hope this helps.
