Vid card not running at full x16 speed.

[society misfit]

I would at least check the BIOS before packing it all up and sending it away.

What do you mean society?

On another crappy note... my dfi board gets to the post screen and hangs... So looks like the video card goes too...

edit: Ok now I'm completely lost... all I did was swap the little 4 pin on the psu and it booted just fine. I'm going to start pulling hair if I don't get this figured out. The only things that are the same from the new computer and this old one are the video card and the psu... hmmmm....

Please read the owner's manual for your MB and make sure everything is correctly hooked up and in place. In short..... RTFM!

And what society means is make sure you have the latest BIOS update for the board before sending it back. Otherwise you're going to be in the same boat with a replacement board.

Hey Nerotoxen,

There are about 10 BIOS updates for your board M4A79XTD EVO, if that is your board ASUSTeK Computer Inc. - Motherboards - ASUS M4A79XTD EVO (your system specs say M4A79XTO - can't find that board on the Asus site). The updates pertain to newer CPU support and system stability. I would check to make sure you have the latest BIOS for that board. It may be the answer to your troubles. Good luck!

I've read the manual plenty of times. What you quoted syg was what happened on my old computer. It wouldn't post and I swapped one of the 4 pin plugins from my psu into the dfi lanparty board. My psu has 2 four pin connections for the mobo. When I put my old dfi lanparty board together with my new video card and new psu it ran fine for a bit then I had to restart windows (updates) and the only thing that came on during rebooting was the fans. So I swapped that 4 pin with the other and it booted up just fine.

As far as the bios updates. I do appologize I had written down the wrong one in my specs, but rest assured I have the latest bios installed. I used the bios updater included with the mobo cd. I think its 2701 version.

Could a possible bad psu cause the videocard to not run full speed @ x16? And cause the random bsods, along with the only thing coming on during reboot is the fans? Not even the keyboard comes on.

Thanks for your patience and help you guys have no idea!

Don't know if a faulty PSU would cause a PCIe slot to run at 16x. However I did experience BSOD and boot ups where only the fans were running due to a loose connection on my PSU. http://www.sevenforums.com/graphic-cards/131951-radeon-6850-sporadic-crashes.html#post1177042

So it's highly possible that what you are experiencing is due to the PSU. Guess you don't have another PSU to test with?

I have a Sunbeam NUUO 550w. I just don't know if it will be enough to power all of the hardware. I suppose I could try it, but maaaaaaan I just took it all apart lol!

 

[society misfit]

There is no harm in trying. At least you may determine that your motherboard and video card is fine.

 

[stormy13]

Looking at the specs of it should be more than enough,

Newegg.com - Sunbeam NUUO SUNNU550-US-BK 550W ATX12V / EPS12V SLI Certified CrossFire Ready Modular Power Supply

One question about it though, how long have you had it? Power supplies can and do degrade over time, and I am finding reviews of that model from back in 2005. If yours is of similar age and been used all along in another build, it may well be time to look at a replacement.

Very good point! But with 2 PSU’s he may be able to determine the root of his problems. I would use it as a reference only. However…if they are both bad (or not up to snuff!!) then unfortunately he’s nowhere closer to finding a solution.

 

[nerotoxen]

The nuuo is old. I haven't had any problems with it though. I'm deff. going to try it out tonight just to get a feel. One problem is though I don't know how to replicate any of these issues. They seem to be hit or miss. The reason I asked about the psu and the x16 is because the manual says the mobo will automatically pick the correct speed. The only way for me to get my computer back up and running if it does the no post nothing but fans is to leave the whole system off for about 1-5 min. then I can turn it back on like nothing bad happened at all. Sorry I'm not answering these questions quicker I'm at work today lol

Wattage wise yeah that should be enough to run your system.
As for the possibility of a failing power supply to cause BSOD's and video cards to act up, yeah that’s' possible as well.

You could always purchase a 15-20 buck power supply tester on-line to check the power supply. You could also probably find one at a local computer store.

Outside of that you could just replace the power supply, but that would be a guessing game if you don't test it.

This is usually an indication of a failing component due to heat; by letting the system rest for a few minutes the system/component cools, which is why you're able to then run the system like nothing after a few minutes if letting the system rest. Something is overheating a component on somewhere. This could also explain why you're getting BSOD's.

Did you get any complete shutdowns?

Try this (to eliminate the 6950 video card) – replace it with your old card and let the system run for a few hours. If you still have issues I would suspect either the motherboard, or power supply.

Since you just got the MB, I would have it replace first, if you still have issue after that, replace the power supply. However as I said before, testing the power supply should tell you if it’s bad.

Let us know.

I just talked with a guy I work with and he's bringing in his psu tester. So I'm bringing in my psu to give it a shot. I've been reading that a failing psu can lead to random bsods and such. I was testing my video card last night with furmark and got another bsod, but I can't even get into windows now. So I just took everything apart and filed an rma with my board. I'll test the psu tomorrow then send out what needs to be sent. Will the psu tester tell me right away? I think it just might be intermittent problems though. I'm hoping it will load it and tell me.

edit: My biggest thing leading me to the psu now is the fact that when I tried to boot several times it would let anything run but the fans. No keyboard no mouse no video.

 

[sygnus21]

Re-read my post - I added some stuff. And good on getting that PS tested.

Good luck.

 

[nerotoxen]

Thanks syg, but my temps are just fine. speedfan wise and other programs that tell me the temp. I've never seen my cpu go over 35c my vid card never hit 75c. That was one of my first concerns...

 

[sygnus21]

With regards to heat I'm talking electronic components like resistors, capacitors, transistors, etc.... these are the components that make up all the parts in your system like the MB, PS, V-Card, etc.

These components are to prone to overheating if something is wrong with them or they are starting to fail. Temp reading programs don't read those components, and it doesn't take a lot of heat to make them fail. It could simply be a component that's failing prematurely or was bad to begin with.

 

[nerotoxen]

Very true syg. Is there anyway of even testing that? Haha! I read somewhere to check the capacitors for bubbled heads and the black "goo" from the insides. Honestly I wouldn't even know where to check to begin looking at seeing if the components of the mobo are overheating. ie what the normal temps would be!

 

[sygnus21]

I read somewhere to check the capacitors for bubbled heads and the black "goo" from the insides.

That's true about capacitors. Here's an article showing what bad capacitors look like - Silicon Chip Online - Motherboard Capacitor Problem Blows Up. Bear in mind that they could look perfectly fine and still be bad. Yes, if they look like those it's obvious they're bad.

As far as testing, unless you have some know-how in electronics there's no easy way to check them other than physical signs.

I would say if you suspect the MB is bad replace it now, it wouldn't hurt to do so just to be safe.

Other than that that's the best advice I can give. Everything else would be a guess as I don't have your system in front of me.

Good luck.

I have this issue on my HP system everytime I update the video drivers, although I've not been able to narrow down the cause.

The way I fix it, each and every time, is to physically remove the video card, and the power to it, and replace it.

I'm not sure if this will help, but I'd definitely remove the drivers, shut down/pwer off, remove the card entirely. Clean the Pci-E slot gently, an old tooth brush will work, replace everything and boot up, install the drivers, restart, and see if that helps.

If you read the entire thread you'd see the OP has basically done what you suggested a few times. Hasn't worked.

You shouldn't have to fix power issues by removing and replacing the video card all the time. The fact that this is necessary says there is a major hardware issue that needs addressing.

In short – under normal operating conditions, that step isn’t a requirement.
