The same old problem with the black screen video card

Hey guys, I've been searching recently and I found that thread.

My problem is kinda the same: My video card (GeForce GTX 550 ti) doesn't work. It IS functioning (its cooler is always on) but it isn't showing any image, just a black screen.

My motherboard (yup, I'm brazilian. Hope you guys understand what's on the page with the help of Google Translator or something like that) is one of the poorest I've ever seen. I totally regret buying it in 2011 - but it was so cheap =3.

I have one more problem: I haven't bought a real power supply yet. I'm with a nominal one (300W) and NVidia tells me that the minimum requirement of W's is 400.

My question is: Will I have to buy a new MB to get my video card running? (I'm probably going to buy a whole new Desktop Computer already with GeForce 600 Series if there's no saving to my actual MB)

UM you'll need a new quality power supply and have you moved the video cable to the new video card?

Yes, I did moved the cable to the video card.

Do you think that if I just buy a new quality PS I will fix this problem? .-.

Your power supply is completely insufficient for that video card. It is likely the cause of your problem.

Go for this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026&Tpk=cx430

That should be plenty.

I can't say for sure if a new power supply will completely fix the issue. Sorry

Looking at PCWARE's site, looks like the board has integrated video (VGA output). Perhaps that needs to be disabled?

Regardless if the power supply is the main cause of his problem or not, he definitely needs a new one. There is no way a generic 300 watt psu will power a 550ti correctly.

Oh thank you guys! This thread helped me a lot! I've just bought a new PS and it's all working correctly!

That's great. Glad it is now working as it should

Just out of curiosity, what PSU did you get?

Man, I bought from a store near my house. It is a Real PS and haves 450 of disponible Watts. Does it answer you?
