Question about Power Color Powercolor RADEON HD 5450 GO GREEN 650MHZ Video Card

Open Question

My monitor no longer recognizes my computer after re-seating my video card and installing new RAM cards.

Hello! I removed my old PowerColor Go! Green Radeon HD 5450 to install a new video card, only to realize my current PSU does not have anywhere to insert my new card's power cords into. So I re-installed my 5450. I also removed two 2g RAM cards and replaced it with two 4g RAM cards. Initially the computer would boot, but the monitor no longer detects any signals from the computer. I re-installed my old RAM cards to return the computer to it's original state, but in addition to the monitor issue, my computer gave off one long beep and two short beeps. According to the troubleshooting website for the ASUS M4A78LT-M LE motherboard (, that specific beep code indicates a memory problem (the motherboard's manual that I have has no information on beep codes). After many attempts to re-seat the RAM cards, I have only found the computer to be content with the new RAM cards, although there have been a few attempts to boot the computer where there was a memory beep code. I have seated and re-seated my video card and RAM cards, but the monitor still does not recognize any signal input. I tested my D-Sub monitor connector and monitor with a laptop, and have determined that those are still good. This is the first time I have personally opened the box (I bought it premade ). I have an Asus M4A78LT-M LE motherboard, Power Go! Green Radeon HD 5450 video card, and two 4g G-Skill Ripjaw RAM cards. I do not know what kind of RAM cards my old ones were beyond the fact that they're 2g each. I admit that I have never opened up a computer before. I do touch the metal case to remove any static before I touch the computer parts. When removing the video card, I initially did not recognize that you needed to lift the plastic lever to release the video card for removal, so I did try pulling on it without lifting the lever for quite some time, but I did not yank it nor tried to force it out. I am certain of that. At the beginning, I was attempting to remove and install the cards with the box sideways, but later I did turn the box on it's side to do so. I've made many attempts to remove and install the cards, and I made sure to unplug the power cord all those times... except for maybe one. It was in my latest attempts that I might have uninstalled and installed a card without unplugging the power cord. The computer was not booted, but I remember noticing that the motherboard's LED light was still on. I haven't noticed any changes in the couple attempts I've made on my computer since, but it is still worth noting. There is some dust in the box, but I do not have a bottle of compressed air to remove it. If anyone has any ideas, I would love to know. Thank you very much for your time and your responses!

    When plugging my D-sub cable into the video card's port with the computer turned on, I noticed that the card did not appear to be particularly secure... I noticed some movement of the card when pushed the connector in, and then the computer suddenly started to give off beep codes for the memory. The card also does not appear to be touching the back panel of my computer beyond the point where the screw holds the card in place.

    I installed a new motherboard and i5 cpu into my old rig. Still no signal from the video card's D-sub connector. Will look for a display cable that fits the ports for the motherboard.

    I swapped out my video card with a scrap video card, and my monitor detected a signal. I tested this scrap video card on my rig's previous motherboard, but received no signal. I didn't think that the scrap video card was in working condition, though, so I didn't share that bit of information here. I have ordered a new video card and psu which should arrive in a few days. I'm about ready to conclude that both my old motherboard and video card are broken?

This is a high end card that needs over $00 watts of power coming from a very good power source. So yes, you need both connectors.

My graphics card does not show up on my Device Manager

I had just run into the same problem while installing my new graphics card earlier today. This is what I did to fix it:

1. Uninstall the new driver for the new card, if you can, in control panel if it installed.

2. Reinstall the new driver.

3. Go to Device Manager and UNINSTALL, not disable, UNINSTALL the on-board card. Don't worry this won't kill anything. It will ask you to restart your computer. Click yes.

4. While the computer is restarting and on the shut down screen for windows unplug the monitor cord from the onboard card and plug it into the new card.

5. Wait for windows to boot up and load the new drivers. It should be working with the correct drivers.

If it takes more than 8 minutes for anything to come on the screen(icons, login screen, etc.) reboot your computer again.

Try installing the drivers for this card. If that does not work, it could be a problem with DirectX, being that it is a DX11 card while you're running DX9, or it could be defective hardware. Make sure the fan is spinning on the card when you turn on the computer.

Old monitor wont switch on

hi friend,
First, try connecting your monitor to a known good PC, possibly the old laptop you are using now. If the monitor works, the problem is with the video card in your PC. If the monitor does not come on, it is the monitor. It is usually cheaper to purchase a new monitor than to have an old one repaired, unless the monitor is still under warranty.

Try plugging a known good monitor to your PC. If the monitor works, your old monitor is fried and needs to be replaced.

If Your monitor works when connected to another PC, the problem could be your video card. First, then you turn on your PC, do the power supply and case cooling fans run. If they don't, it could be the power supply.

Next, open the computer case. Before you do anything inside, unplug the power.

IMPORTANT!! Touch any metal portion of the computer case to ground yourself to the PC. The slightest static spark can destroy computer circuits.

If the video card is the card type that plugs into a slot on the motherboard, remove the retaining screw or fastener at the top of the card, carefully remove the card, handling the card by the edges as to not disturb the circuits on the card, and re-install the card. Sometimes simply re seating the card corrects the problem.

If that doesn't work, replace the video card with a similar type card. Maybe now is a good time for a video card upgrade.

If the video card is integrated into the motherboard, you can only install a new card into one of the PCI slots on the motherboard. When the PC boots for the first time, go into bios and disable the on board video card. hope this helps u

Have emachines W2060. Can't get screen to show

Hi Joe,

Could be one of several things:

1) Monitor cable connection loose.
2) Video card (if you have one) not seated, or bad.
3) RAM module not seated, bad, or wrong kind. (If you have not messed with the RAM, probably not one of these.)
4) If your video is integrated into the motherboard (no video card) your motherboard may be bad. Installing a separate card could correct this.
5) Bad monitor.

Have you made any changes to your system when this happened?

Try to connect another monitor/cable to your computer and try your monitor on a friend's computer to see if it works.

Comment back with any updates.

Thanks for using Fixya.

My video connection does not work monitor says "no signal." I checked all connetions and they's properly connected.

Check to make sure you have correct ram installed in motherboard as the video card may share that ram. Check CPU that it's installed correctly and video should work. If not then the motherboard is bad.

Display issue can card's cmos (if any), be reset?

There is no bios on the AGP card. Uninstall the PowerColor driver software including any other software the CD may have installed. Than open this link;
Download RegCure & install. Let RegCure clean your system.
Shut down the system & install your AGP x1550 card. Re-install the driver software. Try playing the game with default settings. Your system & AGP card has more than enough power to play the game. If the game messes up or your system freezes send it back to PowerColor. Its not your system it has to be the card.

No video at startup

The beep code you mentioned is either a video problem or RAM problem, that is what the beeps mean. Check your RAM one by one in case you got a bad stick, making sure they are properly seated in the slots. Since a new video card did not slove the problem then it also could be a motherboard issue, video slot dead. If your motherboard is still under warranty contact the manufacturer to see if they'll send you a new board. These are the common problems for the symptoms you describe. Hope this helps.

Black screen

I have three suggestion. Since your currently using your old video card now I'd like you to update windows. You need to have at least .Net framework 2.0 installed in your PC. Do not skip installtion of earler version of .Net framework like 1.0, 1.1.
If you haven't updated in a while this may take some time.
Download & install DirectX 9.c at this link:
Download your latest drivers from PowerColor here:
Restart the PC. After windows finishes loading remove your older video software from Control Panel -Add/Remove. Shut down PC, unplug power cord. Remove older video card, clean slot with a blast of canned air or clean paint brush. Install newer card. Make sure it is seated correctly. Re-connect Pc & boot to windows. Install downloaded drivers. If your card continues to wig-out after 10-45 min, it might be over heating. Make sure you have plenty of fresh air to enter the case.
