please help me screen goes back after a new graphics card

Specs: Windows 7
Hey I'm not sure where to start but a while ago I bought a desktop and a monitor and they are

Desk Top: - Acer Aspire AX1420-UR10P (PT.SG9P2.003) Desktop PC Athlon II X4 645(3.1GHz) 4GB DDR3 500GB HDD Capacity NVIDIA GeForce 6150 SE Windows 7 Home Premium 64-Bit


But the graphics card that came with the computer sucked, it simply doesn't support 3D games.

So I went ahead and bought this graphics card:

Graphics Card: - GIGABYTE GV-N520SL-1GI GeForce GT 520 (Fermi) 1GB 64-bit DDR3 PCI Express 2.0 x16 HDCP Ready Low Profile Ready Video Card

Here note that the maximum power my computer has is 220W but the graphics card needs at least 300W for it to run

So I bought this power supply unit:

Power Supply: - Antec VP-450 450W ATX 12V v2.3 Power Supply

Here's the story:

After I bought my computer and the monitor I bought the graphics card. It took me a while to figure out how to install it, but I worked my way out and installed it. So I followed the general guide to installing graphics card, remove driver first, install card, (the computer didn't have a card so the pci slots were empty) then I started my computer and tried to install the new driver with the disc that came with the graphics card. The first time it went so well that I thought it's gonna work, but after a while the screen suddenly goes back and on the top right corner it says "VGA then DVI..."
It's the screen you get when the monitor isn't plugged into a desktop.

So after that I went to look at my computer and the card and I found out the card needs more power, it needs 300W but the computer has 220W.

So I bought a 450W power supply unit, also took me a while because my case is micro ATX board. I have to leave the power supply unit outside the case.

So after I installed the power supply and the graphics card, the first time trying to install the driver also went pretty smooth but the screen then went black after a while. So I'm wondering what exactly I should do, I'm pretty sure the power supply is working. Atm I'm using the power supply but not the card and I can run my computer fine.

Addition details :
When I tried to uninstall the original graphics card driver, it kept automatically installing itself when I restart. Could that be why? But after I uninstalled it I switched to the VGA port on the new graphics card, but it still didn't work.

I have my directx updated to version 11.

Please if you're confused about anything I said tell me which part you didn't understand and I'll try my best to describe it!

Thank you for your time.

The integrated geforce 6150 can play 3D games. Both integrated and video card doesn't support nvidia 3D gaming.
GT 520 it was created for the purpose of viewing high definition videos. The gaming cards starts from GT 540 and go upward. 300W power requirement is for the whole system, the card use only 29W. Get driver direct from nvidia website. ATX power supplies fits well in full and mid tower cases, they doesn't fit in slim cases.

As for power supplies, if you go to Power Supplies on Newegg, on the left column you will see a heading "Type", under this there are "Micro ATX", "Mini ITX"" and others. Look at a few types and read the dimensions and compare them to your original one to see what you need.

There is one step you skipped, you may need to go into your BIOS set up and tell it that you are using PCIe (or PCI) video instead of the onboard video. Look up your manual online for the key you need to tap on boot up to get into the BIOS set up. You will have to do this with the onboard video and then switch it over.

Look into a low profile version of the GT540 or above as Kuwese indicates. The level of the card will be determined by how much gaming you do and how much you want to sink into this computer as well as what power supply you can find to fit.

Good luck.

It's a shame you didn't post questions before you bought the Acer. I'm sure you would have been advised against it. The board is based on the outdated GeForce 6150 SE/nForce 4xx chipset combo which was introduced about 7-8 years ago plus the case design limits upgradeability.

If you look at the image gallery at Newegg, it shows the inside of the case with a clear shot of the power supply. The Antec PSU you bought is a standard ATX but it appears the Acer case requires a SFX12V:

Regardless, there's no reason the original 220W can't handle the GT 520. It's not a gaming card, it's a low power HTPC card. As kuwese said, it only uses 29W, & that's under full load. At idle, it uses about 10W. This site shows the power consumption as 6W idle & 31W full load:

If the onboard video driver keeps installing, it's because the onboard hasn't been disabled. Enter the BIOS & find the setting to disable it. And make sure to return the shared RAM back to the system & change the initial display to the PCIe slot.

It's probably too late to return everything, but if it's not, send everything back & start from scratch. We can advise what to buy to build a decent gaming rig. You'll never make a decent gamer out of what you have.

Also this is my next computer which I'll be getting if this one doesn't work well, please check it for me and tell me if it's good or bad.
I'd like to thank you for your help and thank you again in advance.

Hey hum so I did go into BIOS. The key to enter that for me is del so I got into the BIOS screen but there are no options that allow me to change it to pci-e

Honestly the only thing that I think is even close to being related to graphics is bios integrated peripherals and the only graphic option in there is onboard graphics controller. But it is shaded, it's not allowing me to change it to "disabled" so i went ahead and uninstalled my driver in device manager then I restarted and went back into BIOS again. Now the onboard graphics controller says "disabled" but the screen still goes black.

I'd like to thank you for your help and thank you again in advance.

I looked at the Acer site and they do not recognize the model number plus they apparently do not show downloads for manuals, just drivers.
Look again in your BIOS, there has to be a way of setting it to recognize the PCIe as your primary video device. It usually is under the first or second tab (along the top) and it usually is titled something related to Video Device or possible PCIe settings.

I am not very familiar with AMD systems and Radeon graphics cards so I will leave that up to someone else to comment on. I am not too familiar with Cyberpower, but I think you may need to go up a step or two for a decent gaming rig. Have you considered a build yourself? What about choosing your components and getting a local shop to build it for you?

I do not see anything related to PCIe at all. The only thing that is related to video is to disable the onboard graphics. It would appear that this should be able to accomplish what you need in activating your graphics card, but you said you have tried this. From your set up screens, I would doubt that you actually have a PCIe slot except that Newegg does show you should have a PCIe 1x and PCIe 16x port (one of each) under the details on your system.
In conclusion, I see that either your power supply is delivering much less than it specified, or the graphics card may not be good.
One final [series of] question[s] though, does your graphics card have a VGA port, a DVI port, or both? Which are you using? Are you using a DVI to VGA adapter? Are you sure you have the card seated properly?
Finally read the 'Feedback' on Newegg's site: because a few are using upgraded graphics (reading the feedback originally might actually have deterred you from purchasing it, or might not).

Hey fingers.

What I have tried is going into device manager and uninstalled the current graphics card driver. But again, it just keeps installing every time I start my computer.

I was told in other sites that the one step I'm missing is to go into BIOS and disable the onboard graphics and change the video output to PCIE. But as you can see, my BIOS just probably doesn't have any options related to graphics.

But yeah I was actually thinking it might be either the power supply or the graphics card. But really there's really no way to test this, but I do plan on getting a new computer soon so if anything I'll just test the card and the power supply out on this new computer I'm about to get.

But is there something else I missed?

And I'm using VGA port, just the VGA. I'm not using any adapters.

And I'm pretty sure the card is seated properly.

Now that I think about it, it's probably not the power supply because the originally PSU has 220W which after reading some of these posts it's clear that 220W is enough for that graphics card.

So the only possibilities are the graphics card or the system is not recognizing the graphics card.

If I correctly understand your first post, the new video card worked
fine for a while, the first time you installed it. So the problem is not
with configuring the system. It must be a hardware problem.

Either the video board, or one of the connections to it, or the
power supply.

The system apparently is trying to use the built-in video because
it is no longer seeing the card you installed.

Hey sorry that's not what I meant.

The card only worked for like 1-2 minutes after I boot my computer.

The first time I installed it I thought it would work, it started fine and I inserted the disc and I was ready to install the drivers but then it went black before I could finish.

I think I'm going to try to buy a DVI connector and see if that's the problem.

But honestly I don't think it;'s the power supply. I replaced my 220W with a 450W and the same problem still occurred.

But yah I'm going to get a DVI cable and see if that helps.

Are you saying that you have video for the first few seconds
during boot, every time you start your computer, but then it
always goes black?

Or does it sometimes work for the first few seconds, and
sometimes not at all?

Or has it stopped working completely?

It just works for a little while every time I start my computer.

But after a while it'll just go black and says no signal.

I would suspect that the graphics card has a break which is
heat-sensitive. Either try it in another computer, or take it to
a shop to have it tested, or return it for a replacement.

But I can also imagine that even the new power supply is not
giving you enough power. You could double-check to be
sure that it really is able to handle each of the separate loads
it carries. The different voltages are each accounted for as
separate loads. The total of all of them is the advertised
wattage. The load of the video board might be too much
even if the total load for all your computer's components is
less than the advertised wattage of the power supply.

Yeah I see what you're saying.

Also I came up with a build on

Not sure if it's good.

I've been advised against buying from cyberpowerpc but it's my only choice, my family doesn't support me physically building my own computer, they think it's too troublesome and doesn't believe I can do it.

Is this any good?

Please take into account that cyberpowerpc is my only choice, but if you have any other website in mind to recommend, please feel free.

I don't want this computer to be like awesome gaming computer, just so that it's able to run most games without having to lag (FPS LAG) and things like that.
