GV-N460OC-IG1, Drivers block windows startup

[Dark Mantis]

Yes it could be the problem. Was it new or from a  previous build?  Although the PSU should be just about big enough it wont have anything to spare and as it gets older it will lose more of its output. Can you list your hardware please?

[wonda]

Thanks for the caring.
Here is mine:
CPU: Intel® Core™ i3-530(no OC at all)
MBO: MSI H55 GD 65
RAM: 2 x ADATA 2GB gamingseries DDR3 1600MHz
HDD: Seagate Barracuda ST31500341AS 7200转32M SATAII 
VGA: Gigabyte GTX-460 OC1Gi(with nvidia 258.96)
PSU: Antec earthwatts 500w
Display: Viewsonic VX2255
Sound card:Creative Xfi titanium
OS: Windows 7 home advanced

I am using i3 internal card now,only replacing GTX460 to see what could happen.Right now it runs quite good.But with GTX460,the system is halted down random,and if I reboot my PC directly I will be stuck by welcome screen just as everybody.I need to cold reboot my computer and Win7 would give me a message,that nvidia graphics card driver causing this problem,the description I listed above.
Thanks again for the caring.

My PC


GA-EP45-DS5
E 8400
6x HDD
2x DVD
4x RAM 1GB Kingston 1066
X-Fi XtremeGamer Fatal1ty Pro Series
GV-N460OC-1GI
Enermax 500W 80+

I measured the voltage on the 12v line, safe mode 12.23v,
 after installing drivers and rebooting 12.23 but at startup win 7 dropped to 12.16 and the PC is stuck.

Right well I think that both of you are asking a lot from your PSUs especially wonda as your graphics card is quite power hungry at the best of times. I will advise on wonda's machine first.

Wonda
Apart from the PSU which I think should be upgraded to a single 12v line of at least 650w, I am unsure as to wheter the problem is purely down to power or a specific problem with the card or drivers. There are new drivers available. They are still Beta versions but I would try them to see if they help. the number is 260.23 I think. They only came out a few days ago.

Sajo24.
Again I think you could use a more powerful PSU really. Your GPU is the same as wonda and a well known power guzzler and with six hard drives and two dvd drives I think you are asking a lot of you 500w PSU.I think it is only the fact that they are both decent makes that has allowed you to run at all.

Neither of you say which cooler on your CPU you are using but if they are third part coolers they can draw some power too along with case fans etc. The other thing to watch are your temperatures both CPU and GPU.

Thx for the reminding.I am under PSU test,will reply as soon as I get result.

[JustMe]

I have the same Problem.
Freeze right after Windows login.

My configuration is:
Mainboard:  ASUS Z8PE-D12
CPUs:          2x XEON E5620 each with Fan
RAM:           3x 4G Kingston DDR3 1333 / EEC
PSU:            Cooler Master 850W Silent Pro
HDD:           OCZ Vertex2 SSD 120GB
Case:          Aero Cool with 4 Fans

Is there a way to check if I need a stronger PSU, without buying one?

[Dark Mantis]

A lot depends on what graphics card/s you are running. If they are high end then I would say you will. Are you using just the one or more in SLI? Can you just borrow one from a friend to try? If not try taking it down to a service centre and ask them to try one, I am sure they will be willing if they think ther could be a sale in it for them.

[pdimitrov]

Just for the record, I have the same problem and after a lot of testing it turned out to be the card.
Only that mine is a GV-N470D5-13I-B

[JustMe]

Just disconected the 4 case-fans.
Baboom, no freeze.

Now I'll buy a 1200W PSU tomorrow and hope that will be enough.
Strange how much power the GTX 460 needs.

Anyway, thanx a lot for this thread. The German Gygabyte Support, couldn't help with this problem.

[Dark Mantis]

Glad to be of assistance. It is always nice to help out a fellow computer user in trouble. Come back and contribute to the forum, we would be pleased to see you.

[Sajo24]

I've swapped GTX 460 and everything is O.K. 500W PSU is O.K. GK series about flawed. Perhaps the memory of GTX 460. Now I'm happy. It works like a clock..

[Dark Mantis]

I am afraid I don't understand what you mean by GK?
However I am glad that you seem to have sorted your system out but i would have liked to know what was wrong.

GK- graphic kart (cart)-GTX 460

[Dark Mantis]

Oh Graphics Card, I see. To be honest your PSU probably just wasn't big enough for the card and the rest of your system.

[wonda]

Hi,I am back to report what is going on.After I received the suggestion,I wrote an email to Antec asking for technical help.He gave me the same suggestion that PSU is not power enough.Cause my PSU have two 12v rails,and the CPU and GPU share one rail,might causing this problem.I also found that maybe the tower fan has some impact(I installed 8 fans and two directly to the Graphic card)I also tested the new 260 drivers,it got the problem worth,I would not install until the WHQL version publishes.My friend use almost the same components as mine,but his system works well when his PSU has only one rail with 40A,600w(His cpu is even I5 750).

So I made two changes:
1.I install a separate PSU supplying power to the graphic card(Actually I test the power supply,when I run furmark and read 150W maximum.)
2.Shut two fans.

Now is better for use,but still sometimes it happens when I boot a game or a HD video,but very few times.However I never get blocked on welcome screen.That is what I feel much happier.
So I would not recommend multi rail PSU for using this system.600w is recommended.
