Hey all
I recently bought a New video card, a Galaxy nVidia 9600GT 256 mb edition
I plugged the card in just like normal, and booted up my computer
The first time, i logged in normal, and started installing, halfway through, the screen just goes blank
I reboot computer
It gets all the way to the loading screen (the XP one, with the blocks sliding across the bar) but before it finishes, it just stops, and the screen goes blank, and i haven't been able to get in at all

I've tried booting up in safe mode, and i can log in fine. I install the drivers without any problem but when i reboot, there are no changes, it doesn't recognize my card, and everything is all laggy

When i stick in my old card (a Asus 7300GS) i don't get any problems logging in

Motherboard= ASUS P5PL2


Any help would be appreciated

Did you connect the power to the board?

How big is your PSU?

everything is connected

yes, the PSU... i've thought about it but forgot to mention it
it's extremely small at 400w
the minimum requirements on the box said 500w


but would PSU cause a problem like this? as i can boot up fine in safe mode

How many Amps are on the 12+ Rails Or what power supply and model number do you have

In Safe mode windows throttles everything down including the graphics. When it attempts to load and run windows in normal mode you are most likely taxing the power supply and causing a voltage drop.

well, i know little about PSUs, so i'll just post a picture
Posted Image\


and just to test if the PSU is the problem (and this won't be part of my permanent setup) suppose i borrow a PSU from a friend and connect that to my video card , so every other part is supplied by my old PSU and my video card will have as much energy as needed.

And if it works then it would probably mean i really do need a PSU


Would this work?

That would be a good way to test the theory.

Just for kicks and grins, would you please post the make and model of your PSU.

And where did you purchase that card, I couldn't find anything when I googled it.

ehh think it's one of these
http://www.google.com/products?q=galaxy+96...cts&show=dd
except the 256mb versions


It's a smaller, cheaper brand compared to larger ones like XFX or eVGA, but it's not bad
think it's a Taiwanese brand, quite popular here (hong kong), though i've never used anything from them

I think it definetly your psu because from the pic it looks like you only have 16 or 18 Amps on the single 12+ rail. I have a 8800GS which is simular to 9600GT and it requires 26 Amps minimum. So im sure the 9600GT would require around the same. Should look into getting a good PSU and if you have the money get one that is 80+ certified.

I found the website for your video card Here You will need a PSU with a 12v current rating of 26amps.

Spec Type ATX V2.2 Maximum Power 450W Fans Dual 8cm Ball Bearing Fan PFC No Main Connector 20+4Pin

+12V Rails 2

PCI-E Connectors 1 x 6Pin

NVIDIA SLI Support No

Modular Cabling Support No

Hold-up Time > 12ms Efficiency > 65%

Over Voltage Protection Yes

Overload Protection Yes

Input Voltage 15V (90-132V) / 230V (180-253V)

Input Frequency Range 47 - 63 Hz Input Current 10A @ 115V, 6A @230V

Output +3.3V@22A,+5V@15A,+12V1@14A,+12V2@16A, -12V@0.3A, +5VSB@2.5A

MTBF 100k hours at max. load, normal line and 25C

Approvals CSA, UL, TUV, FCC



This is an example taken from a Rosewill power supply this model has 2 x 12v rails 1 @ 14A and 1 @ 16A combined for a total of 30 Amps on the 12 volt rails. This would meet the needs of your system. A Antec True Power, Rosewill Stailion Series (the one posted above), Or the Thermaltake are all Reccomended manufactures in that power and wattage range. I found all of these at Newegg.com . If you plan on doind SLI in the future you will need a power supply Larger than 400 watts.
