Black monitor after installing Gigabyte GT 630. Help!

[epetry]

Hi guys,

I have a Packard Bell iMedia 8552, which i have been using for quite a while and has always been working properly. I changed the PSU for a TooQ ATX 600W and the old graphic card for a new GigaByte Nvidia GT 630. All the cables and everything are installed fine and seem to work. I connected my monitor for the first time to the new graphic card's VGA port, and while the PC turns on the monitor remains black and on standby mode.

The computer itself runs fine, it doesnt give any beep signals. Though, i doublechecked if the RAM cards are inserted correctly and gave them a clean and they seem good as well.

What could the problem be? I doubt it's the RAM or the motherboard, so any advice? The PSU is 600W, which is far more than enough, so that can't be the cause neither i think.

the motherboard has a nvidia video chipset built in. with the gpu in is the onboard video still the main video or did the mb switch over to the newer gpu. if the onboard is on but not the gpu. under primany display set it to peg/pci. make sure your running the newest bios for your pc.

I just tried by taking the GT 630 out and putting the old graphic card in, and it doesn't work either! It doesn't even work by connecting the VGA to the onboard GPU port. I cant acceed to the BIOS or change anything because no matter where I try to connect the VGA, my monitor remains black and on standby mode, as if it wasn't receiving any signal (i can't see anything). The monitor does work fine cause it shows the LG logo after plugging it to the electricity. My computer sounds and seems to run normal as well. Im desperate cause I don't know what the problem is, or how to find it.

Place the old PSU back in, if it's working fine with the old card then it would mean that the new PSU you bought is dodgy (haven't heard of the one you bought but it's probably more of a 350W PSU)

If it's working with the old unit, replace the PSU you just bought, uninstall the old graphics drivers with your old card and user driver sweeper/fusion, then remove the old card and swap it with the new card

If your BIOS settings are set to PEG/PCI then you should boot into Windows where a generic video driver will be installed, upon reboot you may install the latest drivers from Nvidia

You need to reset your motherboards bios. If you can't get into the bios then unplug the power supply and take out the cmos battery , then push the main power button for 10 sec. to release any stored power in the caps. Wait another 30 sec. and then put the battery back and connect the power supply.
This may help.

Both were working fine before I changed the card and PSU. My PSU is a 600W TooQ Ecopower II ATX. It says its efficiency is around 75%, and my computer was working with a 250W PSU before installing the new graphic card, so it should be fine. Even if it looses a lot, there would still be more than an extra 100W for the card, which is more than it consumes.

Just tried it. Took the battery out and followed your instructions. Didn't solve the problem.

One thing i noticed is that whenever my VGA cable isnt connected to any card or integrated GPU (just with one end disconnected and laying on the floor) my monitor stays with the green small light on and displays the message "looking for connection". As soon as i plug it into any of the VGA ports (integrated GPU or separate card) the monitor says "returning to energy-saving mode" and goes standby. Don't know if that is relevant in any way, but sayin' it just in case.

My monitor in case it helps is an old LG Flatron L1730S. Still seems to be working fine though.

Im beginning to suspect that my motherboard has some huge issues, but it just seems kinda weird to me that the thing was working nicely right until i changed the card and PSU, and then suddenly gives me trouble. Didn't break anything during the instalation as far as I remember.

Also, my CPU is AMD. Could this be an issue?

on the mb there a four or eight pin power plug did you re connect it???

Well, to the MB i connected the 24-pin and also a 4 pin. The problem is that my PSU didnt bring a 4 pin, just a 8 pin that you could split into two 4 pins, which i did, and then just plugged one of both in as that is all that my MB needs.

Regarding the power that the card consumes, the user's instructions say that the GT 630 doesnt need an aditional 6 pin either as it draws all the energy it needs from the PCI, so i just plugged it in the slot and thats it.

-Still having trouble and open for more advice.-

Did you try the old PSU again.

So, the black screen problem is solved. I brought my computer to a tech and apparently the graphic card was incompatible with my motherboard. I changed it for an older graphic card that works with it, an AMD Radeon HD 5450 1GB DDR3.

Now, I have another problem. I installed the drivers for the new graphic card, but when I open the Device Manager, it says that the controllers for the graphic card are missing. I installed all of them correctly with the driver CD that came with the graphic card. How can i fix this?
