 Posted: Tue, 8th Dec 2009 19:20 Post subject: Computer won't post |
|
 |
Hello everyone. After leaving the computer for 2 days turned off, I found out it won't post. The PSU feeds power to everything, fans, HDD, ram, GPU, but it won't post. I haven't changed anything, this happened suddenly. I'm using it normally and shutting down, and then two days later, it just won't boot.
I got around to booting it by holding the Power button down for 10 seconds, then pushing it again. Used the PC fully for 10 days (without powering it down), even tried hardware-exhausting stuff such as benchmarks and the latest 3D games. I memcheck'ed the RAM.
I got the PC down to barebone, just CPU and RAM, still no post. Removing the RAM does cause the speaker to beep the known "no RAM" tone, but using any of the two dimms I have won't let the computer post anymore.
I (to my stupidness) followed everyone's comment and spend 70 euros and bought a new Mobo. I had a friend replace the motherboard and connect everything, still same result. I used a different PSU, getting power from it only to the motherboard and CPU just to try it, still no post or any other beep. I've even unhooked the front USB cables, in case they short-circuited.
So now we're down to CPU and the graphics card I assume, but even those have me scratching my head, as the computer went from no boot to full-blown usage for hours while playing games or doing CPU intensive stuff with no failure.
Any ideas?

Have you no other GPU to test?
Are the fans etc spinning up on start?

Nope, but I'll try to find one from a friend. Yap, everything gets power on boot, from the last fan to the HDDs.

It happened to me once, it turned out the case was short circuiting the motherboard... If all else fails, before spending cash on new hardware, try removing your motherboard from the case and running it on a newspaper. I ended up eventually replacing the case.

lol I remember that, you were going at it for a week.
Sounds like a motherboard issue period to me, of the builds I've done and other I've seen when shit like that happens, it's ALWAYS the motherboard being no good or ends up failing.
You got another MB you can test out? |

Do what Leo suggested and put the board on some newspaper or cardboard and test it.
My bet is it is the CPU (judging from what you have wrote). |
Could be bad luck. Built a gaming rig for a GF at the time and took me 3 asus boards to get one that worked. |

I had this issue once with Intel i7... Everything powers up but no POST beep.
After spending days trying to figure out what's wrong I got my DO'H moment. I have forgotten to plug in the processor's supplementary power cables because I7 needs it for its 4 cores...
Have you tried a new PSU? Maybe the power supply to your processor is down (broken cables or something)?

something easy to do aswell would be resetting bios cmos (battery thingy on the mobo ^^) just to make sure it isn't some bios setting causing an issue.

you guys missed his post lol ... he had his pc running all the time, then turned it off 2 days ... this cannot be a power issue or whatever. Else his PC would have failed before.

Thanks for all the suggestions people. It's true that as Sin says, I had my computer running for days and for hours at full power (casual 3D gamer) both CPU and GPU wise. Never had any problems with BSOD's, the computer shutting down by itself, the graphics card driver resetting or anythnig, I've been smooth sailing for quite some time.
After a day's work, I shutdown the computer, go out for 2 days, return home and when I tried to turn on the computer, it just wouldn't post. I got around to getting it to boot by randomly holding down the power button for 10 seconds with the PSU switch on and then off. It worked once, I kept it on for a week, and then when I made the dear mistake to turn it off, it just won't turn on again.
And that's just what makes me wonder. I mean, can a CPU be running at 100% for hours before not being able to boot and AFTER the workaround too, but still cause problems on the computer booting? If the Motherboard was short-circuiting, shouldn't it be doing whatever it's doing for some time? Wouldn't the workaround have failed in the first place?
And I know it's not the motherboard or the specific power connectors per se, because both the previous and new motherboard exhibit the exact same symptoms.
Although I should mention that I got the computer to give me an audible POST error by removing all RAM from it.

So you still haven't fixed it? Test all the parts individually

Mobo - thats my guess. I had same issue on a brand new mobo and cpu build. Would not post. But everything else went on. I even tested the mobo on the antistatic bag outside the case. But.in my case the pc never did boot at all. So I think something must have shorted on your mobo when/after you shutdown.

So, the previous MoBo shorted, I got around to having the PC work for a week, then it shorted again, then the new MoBo that I replaced the old one with shorted too?

Another CPU didn't solve the issue either.
A weird thing, don't know if it's a clue. When the computer is in this turned on but no post state, when I press reset, it turns off, stays off for a couple of seconds, maybe three, and then turns on again.

My PC used to turn off for a few seconds and then turned back on by itself but that was after shutting it down. Turned out it was because of the RAM. I used 4*1GB OCZ Reaper 1066 and for some reason my mobo didn't like it. I have 2 of them in at the moment and another 2*2GB OCZ Platinum and it doesn't do that anymore, which I thought was strange.
You should try to borrow some RAM, CPU and gfx card from a friend to test with yours and then test your parts in someone else's system.
Have you tried different RAM after clearing the CMOS?

Replacement test RAM is on the way. That's my last resort. I've tried two motherboards, two CPUs, two PSUs, and even everythnig out of the box in case something shorted. Nothing has worked so far.
And the GPU was crossed off the list early, since the computer wouldn't post even without it (it should complain about no display adapter being present with the according POST beeps).

Good luck. I know how frustrating it can be when that crap happens. Worst thing is buying new parts only to find out they didn't need replacing.

I know, already got screwed. Everyone said motherboard, and there went 70 euros down the drain.

Yes, I tried another PSU. Replaced the RAM, now the computer beeps once as if all is OK, the monitor gets out of no signal and into a blank screen, nothing happens for a few seconds, and then the computer beeps again, without any signs of it resetting.
With the new RAM, the reset no longer shuts down the computer for a while, just causes the short beep post again earlier.

Hmmm it's starting to sound like your PSU may have fried Everything before you replaced the motherboard.
Not for sure but it looks like this is a decent possibility.
You have tested the GPU in another system to ensure it's not dead?

Well, quest is over. It was the RAM dimms. Two perfectly good Corsair Ballistix dimms died concurrently? I can't imagine it was so. But having replaced those with another dimm (low quality mind you) the computer not only posts, but works just fine.
So, off to buy some new RAM tomorrow. Any recommendations on a not-too-expensive yet good replacement?

Could it be that they were not working because they are not getting enough voltage? You shouldn't have the trouble you had but it looks like they need 2V to run properly (that was a quick google check and I could be wrong about the 2V).
DDR2 prices have gone up a fair bit from the last time I bought some.

2.2v usually for crucuial ballistix (at least my sets are all 2.2v)
a bit of a lower voltage wouldn't cause this however.
