Got up this morning and noticed that my main cruncher (i7/950) had shut down sometime after 02:00 this morning with a red led lit on the mobo that is not normally on. I reseated everything including new thermal paste, powered up and the red led came on immediately, no beeps, nothing. Has the mobo has gone to the great beyond? Since my other machine (i7/930) has the same basic configuration, I will try to swap everything over to it. Either way, I am apologizing to my wing persons up front for which ever machine ends up being down, it will be at least a month before it can be replaced/upgraded.

Before panicking check what the LED means - look in the motherboard's manual.

There is nothing in the manual on this, I've checked the manuals for both versions of this board (Intel DX58SO).

There is some info on page 35 of this document that talks about LEDs.

Is the red LED between the CPU and the chipset? If so it sounds like it is one of these two:

• The CPU LED (Figure 6, A) indicates an elevated temperature on the processor that could affect performance.
• The VR LED (Figure 6, B) indicates an elevated temperature in the processor
voltage regulator circuit that could affect performance.

Seems like you may now have extra parts for the other system.

i would try the obvious cluprits

power supply
ram from a known working machine
cpu from a known working machine

unplug everything from the board not needed for operation
check if video card is ok

then see if it posts with minimal components plugged in

if all that fails it s time for a new board

also keep us posted

I came down with a bad case of i don't give a crap

I would guess the PSU died.

that would be my best guess too but you never know

I came down with a bad case of i don't give a crap

The power went out for about 3 seconds a few weeks ago for me, and this has happened 10+ times since I last had good batteries in my UPSes, and my system always came back on just fine. The most recent time.. it wouldn't do anything at all. Press the power button.. absolutely nothing. No LEDs lit up, no beep codes.. nothing.

Moved the CLR_CMOS jumper for 10 seconds with the PSU unplugged and moved it back, pressed power button.. all came back to life. Just had to re-do my settings in UEFI configuration and back up and running.

Give the CLR_CMOS jumper a try. Might work.. might not. Doesn't cost anything to try.

clr cmos had nothing to do with it psu was in safe mode protecting itself

i don t understand why ppl always clear the cmos for no aperant reason
leave the cmos alone unless you overclocked it so massivly that it don t post

I came down with a bad case of i don't give a crap

any news on the patient??

---

I came down with a bad case of i don't give a crap

OK folks,

The surgery was successful even though the patient DIED!! - and the funeral will be tomorrow at 10:00.

The culprit was the mobo, it went south, died, kaput, etc, etc.

1) New CMOS battery - no joy
2) Swapped PSUs - no joy
3) Swapped CPUs - JOY!!!

Took all the essential things (CPU, GPUs, drives) from the A-SYS - i7/950) machine and swapped out with those in the B-SYS - (i7/930) machine. At this point in time the 930 machine does not exist, and will be replaced with an upgrade as soon as the money is right. I can't see spending a couple hundred replacing the mobo with another of the same, if I could find one on the net. So the replacement will be a i7/4770K bundled with as ASROCK Z87-EXTREME-4 ATX board for around $348 + tax. If onboard GPU is up to snuff and I can play my simple games and watch DVDs with no problems, then the GTX660s will do pure cuda & OpenCL work. My only concern are the memory sticks. My current sticks are 3 x 2GB Corsair Dominator PC-12800 sticks triple channel. Can I use these in a dual channel machine?

I again apologize to my wing persons for the inconvience.

---

I don't buy computers, I build them!!

yes you can but you might have to buy 1 more to get it to run dual channel

triple channel sticks are the same then dual channel

triple channel = 3 in a box dual channel = 2 in a box

i just brought my 8350 amd machine online but it seems it has some issues with random reboots so i guess i be testing rams for the next 2 days and see what the problem is

also i wold look at something else then asrock their boards are not very good to put it mildly if you want to spend 300 bucks on something get a gigabyte or asus

just my opinion

So... I was giving a suggestion to try, and you said that was just wrong and a pointless waste of time because you already knew the problem... and then you, too, were wrong. Good job.



And also.. in my situation that I have experienced.. by your logic.. I should have just thrown everything away and bought all new hardware because I didn't OC and my board appeared to be dead? Wow. That's just crazy. I really hope that's not how you troubleshoot your own hardware problems, for your wallet's sake. Moving a jumper for 10 seconds fixed mine... so why would I start replacing parts? [done]


OP: good to hear that you figured out the problem. Sucks it was the board, but at least all the other parts are okay. PSUs are pretty good about not taking everything out when they go, but boards are roulette when they go.

Linux laptop:
record uptime: 1511d 20h 19m (ended due to the power brick giving-up)

completely taken out of context but ok

what i ment was that your machine would have started up without resetting the bios

most modern power supplies protect themselves from damage by not turning on until the power was removed for a reasonable amount of time after sudden power fluctuations aka brownouts or splitsecond power interruption

clearing the cmos on a machine that worked perfectly up until it died is pointless and should only be done as a last resort after everything else fails

a good example is the x58 mobo from evga run with a i7 950 which in some cases would not post after cmos clear due to a bios bug

so by clearing the cmos you would introduce another variable which in turn would have prompted you to assume your board or cpu was bad and you would have thrown it out tyvm

I thought that it was the other way around, that ASROCK was the better one. When I'm able to put this all together, with the unlocked CPU I can bundle any mobo and still get the reduced price - around the same amount of money. Can you suggest a good one? As far as the sticks are concerned, I can pull one from the dead machine since they are the same configuration. At that point the i7/950 machine will only have 4GB ram in a dual channel config.

Actually ASRock is owned by ASUS and my 2500K has been sitting in an ASRock Z68 Extreme4 quite well over the last 4yrs with both dual and triple GPU setups.

Gigabyte is a totally different story here as I had nothing but quality issues with them several years back and I will not go back there.

Cheers.

I can't stand Gigabyte either, same problems.
