Hello,
My friend just put a Corsair 850 watt power supply in his HP P6404y machine and tried to upgrade the Nvidia 9100 stock video card to an Nvidia GTX 460 and the machine would run fine, however when he tried to play games the machine would start beeping and shut down which is usually a symptom of a GPU overheat condition. He then returned the GTX460 and upgraded to a PNY GTX 470 thinking his first card was from a no-name vendor and the same problem occurs. He then put a large fan next to his computer with the side off and if the machine starts beeping he turns that on and can continue to run, but I told him that option is not recommended. There is nothing in the Bios to see what the settings are for heat monitoring on a GPU, and there is no log generated showing what the cause of the shutdown is. We have looked online for help and there is none available for this Pegatron m2n78-la motherboard made by Asus for HP. Is there any software
that allows us to monitor and change the settings for heat ranges on a GPU, or is there any other way to identify what the machine is monitoring for heat so we can try to fix this. The bios options are very limited so we really are stuck on this one. Please help!! Thanks

P.S. Here is a link to the system specs. from HP.

The sound is more of a constant tone, no codes. It is very loud and it runs constant until you either quickly exit out of your application and get the temp on the CPU to drop, or it just shuts down the system without any log entry. I still think the voltage is set wrong as shown on that link I posted earlier, and that will be our first shot this evening. Wish us luck!

Voltage is really easy to figure out. Open CPU-Z and it'll show you the voltage for the processor. Then compare this to what AMD shows on their website. It's as easy as that.

If the voltage is too high, you can often times change it in the BIOS, unless HP has a locked BIOS.

That is our plan. I find all kinds of info showing this:

Phenom II X4 820 C2 2.8 GHz 4x 512 KB 4 MB 2 GHz 14x 0.9 - 1.425 95 W AM3 Q3, 2009 HDX820WFK4FGI

Which shows the voltage can be anywhere from 0.9 to 1.425. I guess we start slow at around 1.115 and go up from there based upon Windows boot and stability. Also my fear is that these settings will be locked by HP, but we will give it a go. What a pain but hopefully others can gain insight from me pulling out my hair...LoL

Just load into Windows and run CPU-Z and see what the actual voltage (VCore) is before you monkey with anything. If it's not unreasonable, don't mess with it. I still think you guys should make sure it's not something else overheating. It could be something on the motherboard (if anything is indeed overheating). But HWMonitor will show temps for anything in the system that has a temp monitor built in. This is why a screenshot of HWMonitor is helpful.

If the voltage is set to 1.425 just lower it to around 1.400.If you go any lower you might have to change the frequency.

Does the computer crash when it beeps or do oyu have to close out of an application for it to stop beeping?

Once again can you plz procide some screenshots of whats happening before and after testing.

The computer will shut down if we don't exit out of the game quick enough. If we exit out as the tone starts we can usually get the CPU to cool down quick enough before the shut down. We will get the screenshot posted tonite.

I just wanted to throw this out their...It is possible that it's just the sensor either by the northbridge or southbrige or anything right above the card that it's getting heated up because the sensor is in a bad spot.It is hazerdous and i dont reccomend it but it's possible to change/turn off the alarm and the fail safe shutdown.But that could be hazderous and fry the computer.Theirs a failsafe installed that if a temperature reads a certain amount it will auto shutdown to save the CPU.You could turn this off to see what happens but it could also fry things.

Well after some intial frustration we decided to take a nite off. The bios is so limited that you cannot change any CPU voltages or settings so the lesson being learned is to just build your own so you can manage your system when you need to. More to come.

Good lesson to learn. They prebuilts are generally "ok" until you want to change something lol.

I used to own a HP back in 2007-2008.Looked like it was the same case as he has.And when i went to go install my geforce 9600gt i didn't see any sticker's on it that would void the warranty if the case was open.Actually now that i think about it,it doesn't make sense for them to have that on the case open if you wanted to install aditonal RAM or a GPU...

Makes sense to me. You pop the case open, cutting that warranty sticker, and insert your RAM upgrade. Inadvertently, you happen to release a static discharge. The system no longer boots. So you remove the RAM and ship it back to HP saying it just died one day. They notice the warranty sticker is cut in half and refuse to warranty the part that's broken.

The reason they would do this is to ensure the system wasn't modified or tampered with (especially by someone who wasn't qualified or who had no idea what they were doing). From a business protection standpoint, it makes a TON of sense to me. Not all products do they need to be so tight with. But everything inside the PC case can potentially be damaged simply by static discharge. It's all fairly sensitive stuff if it gets zapped. So I can totally see why they'd refuse to cover this thing and put a sticker on it to ensure it was never opened.

If HP doesn't do this, and accepts the false warranty claims as a "cost of doing business" then good for them. :) And for the customers who break their stuff. LOL

Problem being can you imagine what the inside of the case would look like at the end of a 2 year warranty period if the thing is never cleaned of dust build-up -- systems require routine maintenance - so although I can see them not wanting the case opened that really puts you in a bad position if you live in a dusty environment or have pets rin the house (my system needs to be cleaned out every month or 2 or the temps start to rise due to dust build up here so I cannot imagine leaving it for a couple years !!) - and I'm sure if the system fails due to dust\debris build up inside the case they would try to void the warranty for that as well !!

Totally agree with you! At the same time, I recall a thread on these forums a year or two ago in which a guy fried his system because he used a vacuum cleaner to clean out the dust inside his case. Static electricity from the vacuum killed the system.

Again, it all comes down to HP (or any other PC maker) having to eat the costs for someone tinkering inside the case who doesn't understand what they are doing. Even using an air compressor isn't safe as it can cause moisture issues.

All my point is, is that the manufacturer may choose to put a sticker on the back of the case where the side panel removes so they know if it's ever been opened. And depending on their policies, they may refuse to warranty a product that's been opened due to any number of potential causes for damage to a product someone else did who knows what to.

I'm not saying HP won't fix/replace the OP's system. However I'm saying I would not be at all surprised if they chose not to do so. And I'd understand their reasoning as to why.

Well i do get what your saying,i have seen those stickers on my XFX6870 and i have seen them on Xbox360.I do understand the reason for it being on a GPU or a Console because it would be modding not upgrading/expanding.But with a computer it is more expandability than a mod becuase it was something that is meant to be expanded.

Well...Things go from bad to even worse... HP has locked down the bios so we cannot fix the wrong voltage setting. According to AIDA64 the CPU voltage is set at 1.672 volts and our allowable range was from .09 to 1.425 volts..... We have looked for several software solutions like AMD Overdrive but it doesn't work with this no-name MoBo. The most interesting and similar post we received was on another site and it led us to this :

http://aiscer.wordpress.com/2009/06/26/the-last-remnant-pc-and-high-cpu-temps/

The info. shown there is exactly where we are, except we cannot underclock the CPU voltage.....Any wanna buy this thing for scrap???

Is it HP that makes the mobo or is that another company?Try going to their website and flashing the bios or download previous or newer versions.

Well if HP installed it wrong, you should defnitly go get a refund.Theirs no way they can accuse you of tampering with it because the BIOS are locked out.

EDIT:If none of the above is possible then get a new mobo.

Well guys.....We have given up. There seems to be no fix for this problem, and we have spent countless hours and money on upgraded gear to try to make this work. We are returning what hardware we can and going back to the old Nvidia 9700 card that atleast runs. Thanks for your efforts, but you can't polish a turd I guess..... BTW Asus makes the Mobo for HP, but brands the board as Pegatron and won't support any bios issues. Also the AMD Overdrive software doesn't even recognize the CPU/Mobo combo and won't run, so you can't use their software solution to modify CPU settings. What a mess.

Hey guys,

Can you tell me if a 460gtx 1GB can run on my 400W Blue Storm power supply from 2004?

The rest of my components are:
ASRock M3A770DE, AM3
Athlon II X3 450 Triple Core (3.2GHz, 1.5MB L2, 95W, AM3) BOX
2GB DDR3 1333
SATA 320GB WD Blue

Everything will be on standard clocks/voltages.

I wouldn't chance it ! --- for a few reasons :

1-- PSUs made 6 years ago distributed the power differently (most Wattage went to the +3v and +5v rails instead of the +12v since older systems used more from those rails) so chances are the Amps available on the +12v rails is not going to be enough to run a modern CPU and a 460gtx.

2-- a 6 year old PSU is probably at least starting to show signs of wear which would mean it has less actual power output than it had new -

3-- even a new modern 400W PSU is under the recommended spec for running a 460gtx.

4-- the PSU is one of the parts of a system that controls all of the other parts and is not something you want to cheap out on

Combine those together and it would definitely make doing so a risky proposition since an underpowered PSU can lead to instability and you risk taking other parts of your system with the PSU when it eventually dies from the attempt and even if it works for a few weeks\months you have to worry everytime that you turn the system on if today will be the day it dies and possibly takes the rest of the system with it.
