My computer hates being vertical ....

[Scrax]

After of a few setbacks (bios) my computer was working fine, but now it keeps turning itself off. I'm guessing it is a power issue but can't identify what the problem is. I am pretty much using the 2000 recommendation. With the Antec 900 and the Silencer power supply. All the power connectors are plugged in correctly. I'm wondering if the problem is the "power chain" or whatever rabbit called it. But because of the fan placement and power cord length I can't do it exactly as he says. I've disconnected all the fans tho to see if that is the problem but just after booting up the computer shuts itself off.

Edit: I have every power cable unplugged except the three required for the motherboard and the two required for the video card but it still shuts itself off shortly after powering up. I dont get it, worked fine before.

That sounds like over heating problems. Does it turn on for a while then shut off? If that's the case make sure your cpu fan is plugged in (never unplug the cpu's fan) and did you use thermal paist? if so did you only put on a little?

[Scrax]

I'm using the stock cpu fan and it seems to be working fine. (No thermal paste.

It looks like the power supply is dead though. I Have NOTHING hooked up pretty much. I took out the sound card and video card. I unplugged the HD, DVDdrive, floppy, and all the fans. The only things plugged in is the big 24-pin ATX connector, the 8-pin Atx power connector, and the aux PEX power connector. And yet when I power up the computer, about 5-10 seconds later it powers down again by itself. There is nearly nothing drawing power from this PSU. (CPU and RAM are still installed) I dont get it at all. The psu was working fine earliar.

Edit:

I'm using a Evga 680i motherboard and a PC Power and Cooling 610W Silencer.

That's the exact same symptom my friend's wife was having. He was overseas, so I went over to check it out for her. Thing is, it was a cheapo power supply (came with a case) which was indeed the problem. PC Power & Cooling test their stuff to last. That power supply isn't that old, so I would think thats not it. Well, I dunno how old yours is, but it was listed as "New" item on newegg like 4 months ago. I wouldn't think it's the processor overheating if it shutsdown that quick now that you have clarified 5 to 10 seconds each time. Atleast in my experience, if you left it off for a good while, it should atleast run 5 minutes before overheating. Best thing I could recommend you do, is try to get in your bios and Load Fail-Safe Defaults (if you have that as an option) and set the "Halt On" to No Errors, again if you have that. This corrected a problem for me, before when I thought it was my power supply. Only thing about that is, the PC was brand new and just got built, so it more than likely is the power supply if it's been running fine and just now started to happen. If you just idle in your bios and it continues to shutdown, the power supply is probably bad. I am guessing you can't borrow another one real quick to make sure?

It could just be a bum power supply...those things do slip out even from the best manufacturers sometimes. I'm sure if that's the problem they would replace it for you.

It could be any number of other things too. Temps are definitely a possibility, and you should probably go into bios and check the temps you can before it shuts down just to see what you see.

Is it possible that the case could be the problem? Are you sure you plugged all the little front panel wires into the mobo correctly? Is it possible the power or reset switches are stuck in or maybe broken in some way?

[Scrax]

Well I started the computer again for the first time today. So everything had time to cool and rest. I was able to reach the bios and switched halt on to no errors and then went to check the temps.
The cpu started at 38C
The motherboard started at 25C
and the MCP started at 48C

However after a few minutes running the temps rose to
CPU 74
MB 35
MCP 74

I imagine those temps are too high right? Could that be what was force restarting my comp? What can I do to make this stop, considering that I had none of the fans running and most of the parts uninstalled. If I hooked everything up, so the inside had proper airflow will everything go back to normal? Bah humbug.

ya, E6600 is suppose to idle around 40C or so. I'm just going to put everything together and see what happens.

Umm, fans. Does this include the heat sink fan on the CPU? Fans are a good thing, so keep building and check temps with the right air flow.

[Scrax]

Ya, I think its okay now. I installed everything once again and now the idle temp is 31C and slightly rising. Didnt skyrocket to 70C yet so thats good. However the MCP is 78C what is that and is the temp as important?

I had disconnected the fans and all the other parts because I thought it was a power supply issue. When I was told to check the temps I hadnt re-attached the fans yet, so I guess that was why the temp rose so quickly. Hopefully now it will behave itself.

Yeah, you are getting shut down due to overheats. Your retail cooler isn’t connected correctly. Also, you do have the fan plugged in to the CPU fan plug on the motherboard, right?

Also, I don’t know if you noticed, but you can plug the fan plugs into each other. I have I think the rear 2 together, and they are connected to the PSU up near the top of the case, then the front 2 are clipped together and they are next down in that PSU plug line. I used the inside clip areas to zip tie the PSU line to the case.

(I didn’t mean remove the CPU fan if that’s what you thought I meant. I just meant the case fans.)

Not sure on that MCP. I don’t even know what that is. :rolleyes:

PS - Someone in another thread mentioned they didn't remove the plastic cover from the retail cooler before installing the cooler :eek: you didn't happen to forget to remove that as well did ya?

[tolliner]

You said you were not using thermal paste correct? Do you have anything between your cpu and heatsink, like a sticky pad? If it's just metal on metal there will be very little heat transfer and will result in a melted cpu

Your cpu should never get above 40c... im amazed it still turns on if it reached 75c :eek:


PS: I think MCP is the same as cpu... maybe main central proc?

Everything seems to work fine after I turned the inside fans on. It is currently somewhere in between 27-32 when it idles. I can't tell how to check it under load yet. I figure I have to download some sort of program?

There is a very small amount of some dinky paste on the bottom of the stock fan. I believe I will be replacing the fan with something better in the near future.

I didnt notice that I could plug the fans into each other..though now that I've been told it seems really obvious. I'm too sick of the inside of that computer right now to go and see if plugging them into each other will help with wire traffic.

I read that the E6600 will be okay until you hit 80C, then it blows up. So I was close!

[rabb1t]

hehehe they don't blow up at 80c, that's where you risk damage, but the bios is set to shut it down at that point. You shouldn't have ever been at any real risk. :)

Don't feel too bad about the fan plugs. At first I thought they were all the wrong kind! (all male ends) :eek: Then I was like 'eeeooooh they are double sided'.

You can check load temperature by just running a game or something like 3dMark and then peeping the temps when it is doing that. (Most games you can 'alt tab' out to do that then go back in.) There might be / should be a temperature sensor program that came with your motherboard. If not I think there are free ones you can download, though I don't know of any.

Now for the hard part. Getting an internet connection :(
