Hey guys. My computer suddenly one day refused to load up Windows 7. I get the OS loading splashs screen, and then it would never go beyond that.

I put in my Win 7 DVD to reinstall, and while launching the software on the disk, the PC would always just hang.

I dunno what caused that. Broken CPU? Memory? Motheboard? I had to gamble. I bought a new motherboard.

-------------------

I bought an Asus Sabertooth X58.

*I place my i7-920 and Corsair Vengeance™ DDR3 1600MHz 12GB CL9 Kit w/3x 4GB XMS3 modules, CL9-9-9-24, 1.5V on the motherboard. (Tried both one, two, or three sticks, different sockets too)

*Put my video card on the mobo. Hook up the two 6 pin PCIE power cords

*Hook up the CPU fan and that giant multipinned mobo power cord

*Plug in my monitor to the video card.

And nothing happens on my screen.... no POST.

There are two LEDS on the mobo that glow red. CPU LED and RAM LED.

So I google around. Loooots of people report the same issue. I send the mobo back to the vendor.

--------------------------

The vendor does tests on it, they manage to install windows 7 on a system based on the card. I get it sent back with an added charge...


So what can I do now? Would you guys conclude my CPU and RAm are broken?

If so... I'll bite the bullet and just buy a new mobo, cpu and ram... dunno what else to do.

Any help, MUCH appreciated!

Yeah man. I'd try a different flavor of RAM. Don't return what you've got, just get two sticks of working DDR3 off Craigslist for $15. Samsung or Kingston. Put them in and see what happens.

try pressing the mem OK button, the board will try various setting to get it to post.

Thanks for the help guys.

I tried memOK! and it didn't work. When I press it, the computer restarts, but I still get no POST, nor does the red LEDs go away.

I've got 3x 1600MHz ram chips that were in the comp when it broke, so I dunno if they work, and 2x 1833MHz ram I've had stored on my shelf for months. None of them worked, tried different setups, just one chip, in different slots etc.

So there are two LEDs on the motherboard, one for faulty RAM and one for faulty CPU. Both of them glow red, so would you conclude that it likely is an issue with both products?

Really leaning towards just throwing it all away and buying a new mobo/cpu/RAM...

Have you verified the dimms are fully seated? Unless you press firmly they may not be. Those ram sockets on mine have latches only one one side and if the other side is not fully seated the board will not see them. I know from experience.

when I first built my system I was seeing only 2 out of 6 gig and that was the reason.

Yeah man, I crammed them into the slots just now, once more, tried a few different setups. Just one, then two, different ones, tried memOK!.. both led's still RED. Audible clicks both on the unlatched side and the latched, they are definitely connected appropriately.

I'm using the beige sockets as well. Tried the back ones too.

Perhaps somehow my CPU and all my memory stick were taken out by a power surge or something...?

I had this same issue with my sabertooth x58.

I reset the CMOS and everything booted fine after that. Check the manual it tells you how to do it. I think you power off, stay plugged in, move the clear cmos jumper, leave it there for 10-20 seconds, then move it back and power up


I did this after having my mem and cpu lights on and this fixed it

Connecting the CPU fan is not required. My sabertooth x58 has the cpu and gpu under water. The cpu fan is empty and the 3 or 4 fan connections are empty on my build

I really appreciate all the suggestions and help here, I really do, especially considering I have zero posts her prior to coming in asking for help. For Karma's sake I guess I must help somebody else in return at some point! :D I've built computers for 15 years, never had such an issue.

Indeed, I realized after posting, that I forgot to mention I have hooked up the 8 pin AND the 24 pin, both of them. actually, the issue is identical with and without the 8 pin.

I have tried both using the jumper cmos restart, and also physically removed and reinserted the cmos battery.

The thing is: I KNOW the motherboard is OK, like I said, I sent it back to the vendor who sent it back to me saying they checked it and it was 100% functioning. I even got a big stack of printed papers output from a program documenting they installed and ran windows 7 on it.

Well, not required, but it sort of is, for the cpu cooling to function properly. I wouldn't want to risk damaging my CPU. Also, what purpose would it serve to not hook the fan up?

I built a system based on the X58 Sabretooth for someone last year. I seem to remember getting the same symptoms and IIRC I was using the wrong memory sockets.

The CPU is listed by ASUS as compatible but the Corsair modules are not on the QVL. However, the RAM is shown on the Corsair website as compatible. So it *should* all work.

What I would do now is hook up a speaker to the board and remove all ram. Then boot

You should get a series of beeps ( 1 long / 2 short - pause - 1 long / 2 short - pause - repeat)

If that happens, this would indicate the board and cpu are OK.

Then plug a single memory module into A1. If you are still getting fault LEDs use the MEM-OK button. If you are still having issues then try B1 or C1 and try each of the three modules in turn.

Good Luck!

I will definitely try this. I'm at my wits end with this system at the moment, but I'd still rather repair it than eat the ~700$ replacement cost.

I've always hooked my chassis up with the speaker, but never had any audio though, but I will give it a shot! Perhaps there's never been any reason for it to chime.

What's hooked up:

24pin to motherboard
8pin to motherboard
CPU fan to motherboard

No RAM
CPU on motherboard
Cooler on CPU
Video card on motherboard
2x6pin power to video card

Chassis power to motherboard
Chassis speaker to motherboard

I press chassis power button, and the fans on both the CPU and the video card start to spin, and LED_MEM & LED_CPU both go red.

No POST, nothing on monitor, and no audio from speaker.

I'm done with this now. Thanks anyway. Getting new stuff, and giving these parts away to friends or something.

The purpose to not hook it up is that there is no fan on my cpu, just a waterblock.

My cpu is under water, the fans on the rads are controlled by a fan controller. By default the bios will alarm to no fan monitoring on the cpu, but you can (and i did) disable monitoring it in the bios

Shame, but I understand your frustration.

Ordinarily, with no motherboard post beeps without any ram installed, I would suspect a failed motherboard. But as you say the motherboard has been checked by the supplier and found to be OK.

Is the motherboard still mounted inside your PC case? Try it outside the case perhaps? (Remove PSU and Motherboard and just hook these up on top of a table or cardboard box or something non condictive). No need to have the video card installed (it would be better to try it like that anyway).

Do you still have the old motherboard lying around? Do this still POST at least?


I suppose the only way to tell for sure is to have a known good motherboard and known good cpu available to swap parts around.

I haven't put the motherboard into the chassis, no. i have it lying on the antistatic bag it came in.

I still have the old motherboard, yes. Man, I'm gonna try that tomorrow (it's almost midnight here), before I do anything.

Originally, I bought the new motherboard because the computer suddenly refused to load windows 7. Even when I put in the DVD and run the DVD on boot, it just frozen when trying to launch the software. I have no idea what might cause that, do you? Any specific components that might cause that?

The reason I haven't tried the old mobo yet, is because I have to reapply goop to the CPU every time, and each time I reinsert the CPU I'm concerned about damaging the pins on the board, but I must try this.

Nothing would please me more than having everything just WORK again.

I have one more detail to add here.

A couple days after christmas I had a lightning strike further down the street from my house. It took out our router, and disabled the network adapter integrated on the motherboard. This is part of the reason I was quick to replace it when the computer failed to boot. However, about a month of time passed between the lightning strike, and the failure to boot.

For quick and dirty test work here, don't bother cleaning and reapplying the thermal paste. I tend to try and make sure that the heatsink is aligned the same way between fittings but this will be fine for short periods.

I'd be tempted to try the board off the antistatic bag at least once more before you swap the CPU over especially if the a/s bag is one of those silver coloured ones. Find some cardboard or something non-conductive to rest it on.

It seems a strong possibility that the CPU is toast and if you put the CPU back in the old motherboard and that fails to boot (which it did before) then that would prove it.

Hello again, Bob. I placed the new motherboard on a piece of cardboard and tested things again, both LEDs still red, no POST.

I transferred the CPU, a chip of RAM and the video card onto the old motherboard, and now that one wouldn't POST either.

What spurred me to even buy the new motherboard in the FIRST place, was that the system on the old motherboard wouldn't load Windows, so perhaps the ram was the issue, and then I might have destroyed the CPU as I moved it onto the new motherboard for the first time.

In any case, I guess the conclusion is my CPU is fried.

I'm just gonna get a new system based on the i5-2500k, new motherboard, and new ram.

I can try and sell the new motherboard, and test the ram on another system. Perhaps sell that WITH the motherboard.

Thanks a lot for your help. I was really aggravated with this, so I'm thankful everybody helped me with troubleshooting!

Hey OP,

I also have an X58 Sabertooth motherboard, and just had the exact problem that you described.

Pressing the MemOK button caused the computer to reboot and get back into that same position: fans on, lights on, CPU and RAM LEDs red, no POST, etc.

I checked the manual and says you need to press AND HOLD DOWN the MemOK button, not just press it. Doing this caused all my fans to go completely wild while I was holding it down, but on release the system POSTed and booted into Windows just fine!

Anyways, just thought I'd share.

Hi guys, i also have asus sabertooth x58, a few weeks ago my pc started turning off and after a few second it turned on by itself, this happened when i usually watched a movie , or started a game , i checked powersupply , processor , graphic card , i also monitored the temperature everything was normal, then i removed RAM and i left only a 4gb stick, my pc didn't boot , then i returned all the ram memory , and suddenly my pc started working again , i did the same thing one time and the pc worked great for a week then it started turning off again. My pc configuration is

Hello everybody. I got the exact same problem as above. My pc worked fine for months now all of a sudden it starts turning off and reboot itself. I thought it was the videocard, wich was very dirty. I cleaned the videocard completely with aceton, put it back and the pc booted again. Then in speedfan the videocard was also a lot cooler, so i thought problem solved. Now, the pc won't even turn any more. The ven starts spinning for half a sec and then the pc shuts off completely. Any help on this?

The videocard is a SAPPHIRE RADEON HD 9650.
The memory is corsair xms3 3 x 2 GB triple channel.

Thanks in advance.
