Computer Shuts Off

[AnitaPeterson]

Now, before you run to buy some other components, look closely at the capacitors on the motherboard... some of them may be leaking... I lost a motherboard like that, and it was exhibiting exatcly the symptoms you describe.

WHOA,

A whole new part I know nothing about!

A) What is a capacitor?
B) What does it look like?
C) How can I tell if it is leaking?
D) What would it be leaking?
E) How can I fix it?
F) Must I buy a new MoBo? It's only a year old!

My comment was that the +12v reading looks too low.

70c-80c is ok for that card with stock cooling. Yes, it's high, but well within design specs. If it gets up past 90c on a consistent basis then you have a problem.

It's doubtful that you've got leaking caps, but to answer your questions...

A) http://en.wikipedia.org/wiki/Capacitor
B-C) http://www.badcaps.com/ident/
D) Brown liquid. Electrolite.
E) Careful soldering on new capacitors.
F) If you have leaking caps, RMA (warranty exchange) through manufacturer.

Hmm,

Well, I checked my capacitors and none of them appear to be leaking...

If they get crooked and then readjusted upright, does that damage them?

 

[galbicake]

Okay...now my problem has gotten progressively worse.

My screen turns into fragmented green, white & black block lines and then the computer blacks out but still is running. I have to do a manual reset.

This is happening only when I play a video game or play a movie off my DVD Rom.

I had this problem before right after I installed my PCR-150 Hauppauge but after I reinstalled all the hardware on my MoBo, it worked fine...

I'm better rested now!

See Lucklyboy's Guide For Complete Users. At the very end, is my psychotic diatribe on power issues. Pay attention to what I have to say about wall outlets and power strips or surge protectors. If those two cheap steps don't work or apply, then get a decent sized power supply! Yes, the card takes less than what it delivers on the +12 volt side of life, but is that the only +12 volt demand you've got going in the case?

Also, remember for every 10F increase in temp. it reduces what your power supply will put out by a corresponding 10%

I've seen all kinds of temps thrown around here. Help an old man avoid confusion and tell me again...

Temp of case at full load and where is the temp proble located? At the bottom, middle or top of case?

Temp under full load of video card?

 

[galbicake]

GPU Stand by Temp - 37c
GPU Active Video Test running 5 minutes - 77c

I have this connected to an APC Backup UPS

I do not know where the temp thermometer is located nor do I know what it looks like. Assistance please.

My specs are listed below.

 

[Luckyboy1]

Yikes!!! 77C is within specs, but barely... yes, but from a preactical standpint, that's barely. Especially after just a 5 minute warm up. The heat bleeds over onto the video RAM and makes it go nuts!

As far as what the temp lead looks like? Well, in my Thermaltake case, it is a black, rectangular thingy with two wires coming out of it. Ewe! Ick, a mini case! Oh well, and there's half of it! Still, with two 120 mm fans, you should be ok. So what's the case temp read after one hour of full load running of the PC?

And your power strip or whatever is how old?

And your wall outlet is in what shape?

I'm trying to save you from a power supply upgrade, but you ain't makin' this easy!

If you are smelling something burning, that is definitely a bad sign. Even though the fans are running, I wonder if any heat sinks are not correctly seated? Have you recently changed any fans/heatsinks on your video card or cpu?
After giving it plenty of time to cool down, I would start it up and monitor your system temps (I use Everest Home Edition) and see if that tells you which component is overheating.

 

[galbicake]

Correction, the GPU stand by temp is 47c.

I have the power supply connected directly to an APC UPS. Everything is about a year old. The wall outlet looks like any other so I do not understand what you mean by "Shape".

Also, what would the location of the temp lead indicate to me? I can find it.

I am not smelling any burning.

I will running a full hour test tonight when I get home.

Thanks

if you had read the guide, you'd have understood the question.

 

[galbicake]

Uhm,

Power Supply or outlet doesn't explain why my GPU is running so high.

I actually did the installation myself and the electrical work is solid so I doubt it is that.

Back to square one.

No! You have to replace your power strip so your temps will drop 4C!

:disgust:

EDIT: According to Lucky YMMV.

ROFL! E-MAZING

 

[galbicake]

Computer crashes frequently when I play computer games or run the DVD player.

I get this pixelated green, white & purple screen of death and then the screen blacks out.

I think it is video card related because even if I do a reboot, it stays like this until I shut down, jiggle the PCI-E card and then reboot.

I would show a picture but I do not know of any free picture hosting sites.

Help?
