Hey, as the title said.. I just bought and installed it in my pc. Everything went normal until I began to install the driver, it suddenly lost its signal and now I have no image at all. What is going on? I searched and I guess the only possible problem may be my PSU.

Here are my complete specs:

Asus MA78L-M/USB3 motherboard
AMD FX-8320 CPU
Corsair CX430 PSU
Galax GeForce GTX 960 2GB DDR5
8GB RAM DDR3

This is wrong, but I digress. OP is having driver issues and now is being advised to replace the power supply. I just don't know what to say.

Your PSU is too small for that system. When you didn't have the drivers your card was running bare-bone minimum. Now the drivers are installed and the higher resolutions are using more resources and requiring more power. But your PSU is too small and no able to provide the required power.

Yes its your PSU 960' minimum psu is 400W and your is 430W it passes the minimum but your psu has to give power to the MOBO,HDD, CPU and it cant with only 30Watts. I also Have The best edition of gtx 960 (Palit Super Jetsream GTX 960 2GB) Well the best from the 2gb edition, anyway and i have Corsair VS650 80 Gold Plus which is 650W and intel i5-4460 . I would recomend to you buying at least the Corsair VS550 Which is 80 plus

Yeah that isn't the issue at all. Power is not your issue. While you really are putting the psu at near capacity.. or close enough it will power your system.

Follow this link

http://www.anandtech.com/show/6396/the-vishera-review-amd-fx8350-fx8320-fx6300-and-fx4300-tested/6

Check the power consumption with a far less efficient 5870. Still 182 watts for the entire system with the gpu idling around 20 watts during the tests mentioned in the link, loading cpu leaving the gpu idle.

So 182 -20 for the 5870 leaves 162 for the 8320 at load but lets call it 200 watts for fun. the 960 has a max power consumption of 120 watts (according to nvidia)

So at load cpu and gpu consume 320 watts and another 40 for memory, drives and peripherals.... in theory, which is plenty of power and will not affect hdmi at all.

1st
try disconnecting hdmi at both ends, connect to the gpu then to the tv

2nd
Disconnect the hdmi connect a cable to the dvi to a monitor.
Download the newest nv drivers
Uninstall all the previous drivers currently installed
reboot
install new drivers
reboot
connect the hdmi to the gpu then tv
enable it in the nvidia control panel if it is not already active then make it your primary monitor.


Would I run that setup on the cx 430 , not unless I was in a pinch, will it affect you in any way except overclocking, no it certainly won't.

My car will run 100 but for how long before it gives out???? You have a 430 PSU the card needs a min of 400 watts but the rest of your system eats watts too so you would actually need around 500 to 550 don't try to run it with anything less .. Besides just your cpu 8320 uses up to 125 watts by it self..

It is the PSU, not sure why others are saying otherwise. Your PSU is barely meeting the Wattage Rating, your CPU takes a lot of power, the rest of your system uses even more, but aside from that...your 12V rail does not have the amps.

+3.3V@20A, +5V@20A, +12V@32A, -12V@0.8A, +5VSB@3.0A

Last I checked the 32A on the +12V is less than 42A. Unless math/numbers recently changed, 32<42

I don't belive so my friend 1 I wouldn't run a system with such a lower end PSU THE CX 430 is not one of the best PSU out there had it been a xfx or seasonic I would of still said the same its his equipment that could go bad if it Fails it could take the rest of the system with it but yes he needs to check his connections and make sure he has them in place.
Someone told him to unplug the HDMI CABLES HMMM sure hope he leaves the system off because in the 20 yrs of building PC,S myself I have seen what happens when a system is running and you can fry the HDMI BY UNPLUGING IT while its on but 430 watts is meger amount to try to run the system to begin with!!!! and I am sure Nvidia knows what they are doing by making a statement that 400 WATTS is bare Min to begin with..

Thank you guys for the answers. But I just need to add some background info: I tried turning it on again, I got image back, but the graphic card coolers simply stop after some time and don't work back again.

Oh, that's pretty damn awesome then. But how would you explain the HDMI signal loss?
