Constant rebooting on DFI nf4 Ultra-D


Recommended Posts

OK, I am at the end of my newbie rope.

 

Just after I am able to log into Windows, my computer reboots. It then goes into an endless reboot loop, each time rebooting sooner than the last. At first I thought it was my memory, because it was failing memtest86. However, I got it to pass memtest86 no problem. Then, I thought maybe the thermal paste on my proc/heatsink had gotten messed up because I removed the proc from the heatsink before I replaced my original damaged Ultra-D. Well, I just put new thermal grease on it and followed the instructions to the letter and I am getting the same behavior.

 

I cannot for the life of me figure out what is going wrong. Can anyone give me some tips as to how to determine the problem suspect? At this point, I don't even know how to figure out what is causing this.

 

One point to mention: I do have a 410W 20-pin Thermaltake PSU which I understand is inadequate for the board, although I have heard of people using 20-pin PSUs without problems. This could possibly be the culprit, but I have to live with it for now while I save up for a new Fortron PSU. In the meanwhile, anyone have some methods for me to deterine what is causing my system to fail?

 

Thanks for any help!

here's the word:

 

if you are not using a recommended 24-pin, 480w psu, that is always going to be the first thing we tell you that you must have before we can really go any further with technical support.

 

we don't tell you the minimum specs on a psu just to make you dance around. We tell you the minimum specs on a psu because that is what they are.

 

if your psu does not meet the minimum specs, then we are only going to tell you to upgrade your psu until you meet the minimum specs.

 

if you think you can get around this with a 20-pin or less than powerful psu that works for you for now, that is up to you.

 

we have a lot more experience with NF4 motherboards than you do. We see the tech support forums and emails every day. We know how many have had their problem resolved by getting a minimum spec psu.

 

If you do not have a minimum spec psu, please make sure you have one before you seek out technical support as we are going to tell you that your psu is not up to minimum spec and is most likely the problem.

Well, I didn't expect technical support from DFI, which is why the question is open to anyone. If someone has an idea, just because DFI's policy is to not help shouldn't mean that no one (especially outside of DFI) can help. If Angry_Games chooses not to chime in, I understand why.

 

PS: Does anyone know of a utility I can boot into with a CD that will stress test various components? Sorry for being so newbish...

Hi blink,

 

Exactly same thing had happened to me last Sunday. However, I knew that it was because of my too overclocked video card. Log into windows, 2-3 seconds, and reboot - continuously - no time to underclock my gpu!

 

Let me tell you how I fix that. First you can try pressing control button just after you log into windows, it may help to set everything to default. But it didn't help me.

 

Instead, I did boot in safe mode, used windows recovery to set my settings same as in two days earlier settings,and VOILA... Of course I lost couple of software that I installed within last two days but who cares!

 

Last thing and perhaps most cumbersome one - try reinstalling windows.

 

PS: Don't feel bad about fortron - it's kinda futureproof and you'll be happy.

Hmmm, my video card isn't overclocked, but I've heard of a lot of people having trouble with the XFX GeForce 6600GT's HSF coming off easily. Perhaps this is my problem. Windows boots into safe mode OK and stays that way for a while so maybe it is the graphics card. How should I go about testing that you think? Is there something I can run in safe mode to stress the video card?

hmm i have seen a couple posts on the xfx cards some good some just mentioning them some bad. I think it more an isolated issue with whatever computer you are running. I dought it would be the grapics card but you can never rule out that possibility.

Well, I reinstalled Windows just to be sure and no dice. I didn't think it was Windows anyway because eventually it would reboot before I even got to the Windows bootup screen. So, now I await the new power supply and hope for the best...

if you can get into safe mode ok but not regular desktop, then there's a problem with the drivers, the install of the OS, or possibly the memory (since safe mode doesnt eat as much system as normal mode when it tries to load every driver under the sun for your rig)

 

you should try some different RAM...ive seen nothing but problems with Corsair memory on the NF4 boards. NOt saying for sure it is Corsair memory that is the problem....but try something different if you can (even if it is on loan long enough to get Windows to install...heck take it to a computer shop and let them stick some memory in it for you and let it load on a counter-top just to verify)

Well, I just bought a Fortron Blue Storm 500W PSU, even though I really can't afford it. I certainly hope that it is the problem because otherwise I am out of options. What are the odds that perhaps the proc is bad?

 

grin...look, your questions are loaded with "guesses"...dont get me wrong, this is ok...but then there's also the problem.

 

If you only "guess" it might be the ram or the cpu or whatever....you will never know or you will sit on your problems the next 10 years.

 

You need more system in your troubleshooting.

 

1) like others said....start up with memtest...let it run....hours.....eg. a good quick start would be 15 or so runs of test #5 and test #8 is also very critical..but of course it is always wise just to let the whole memtest suite (all 8 STD tests) run eg. overnight or something.

 

1b) If memtest passes...well this is GOOD ---> but it dosnt mean **** yet regarding performance and stablility in Windows. Sad but true.

 

2) memtest passed ? So..go ahead and troubleshoot your CPU with OCCT or prime95....let this run for hours and check how stable your CPU is.

 

Also...make sure that your LDTxHTT is BELOW 1000 and make sure that chipset voltage and LDT voltage (in bios) is set ONE notch higher than the default is.

 

ALso....usual trouble shooting procedure requires a BARE MINIMUM system to start with..eg. NO USB devices, no modem, no NIC, disable everything unneeded in bios, use only ONE memory stick etc. and start system step wise with the bare minimum and do your testing (memtest, prime etc...).

 

3) if you are past this you can say your hardware is working ok, your overclock is stable...it SHOULD be a software issue according to common sense since memtest is ok and prime is ok too.

 

So.;.check your software/OS install and verify system files....eg. Startmenu, run -> msinfo32 --> menu tools "system file signature checker" and check your system files. They could be damaged.

 

etc..etc..

yes...410W is kind of on the very low side..and then 20pin in addition..i'd be surprised if its NOT the PSU.

 

You can also go in bios (at least you can do that, right ?) and eg. read the voltages for CPU, chipset etc...what does it say there ?
