Computer Shuts Down When The GPU Temperature Goes Over 95'C, Will A Ne

We like to watch TV + movies on our Sony TV/Monitor.

Our current Graphics Card (+ computer) is around 2 Years old and just recently when ever we try to watch TV + movies the “SpeedFan” indicates that the GPU is over heating. Going from around 90'C up to 95’C and hotter, and then the PC shutsdowns everytime.

My computer still works when doing simple web browsing or writing a Microsoft Word docment.

But now, every time we try to watch a video (TV, Movie, MTV) my computer’s GPU overheats (@ 95’C +) and shuts down.

My Question Is: will a top notch Graphics Card Solve this over heating problem?

(My definition of “Top Notch” being a graphics card reviewed here costing around $700.00:

Like a “Radeon HD 6990 ($735.00)” Or a “EVGA GEFORCE GTX 590 {$779.00).”)

[*Note - my girlfriends relatively new Think Pad laptop is currently what we use to watch TV + movies. I don't understand why her little lap top can show TV + movies without stuttering/overheating, while my more powerful machine overheats?)

I currently have the following setup:

NZXT Black Case 2x 150mm Case Fans
Cooler Master 650W Extreme Power Duo
Intel Core 2 Duo E8400 LGA 775 3.0 GHZ 1333 6M
Kingston 2 x 2GB DDR2 800 6400 240 Pin Dimm
Seagate 4 x 500GB 3.5” Sata 16m ST 3500 418 AS
LG DVD 22 x GH 22 LS30 Lightscribe SATA Black
Video Card PNY 9800 GT 1GB GDDR3 VCG981024 GXEB
ASUS P5N7A – VM MATX Mother Board
Vista Home Premium OS 64 Bit OEM

Monitor 52” Sony 52HX909 (94.5 lbs.): HDMI Video: 480i, 480p, 720p, 720/24p, 1080i, 1080p, 1080/24p

1. if all you do is watch TV and don't game then those cards are way overkill, a simple $40-50 will be more the adequate.

2. before you invest in money into another card, I would clean your case and fans of any dust. then re-apply a new coating of thermal paste on the GPU.

That card should be more than enough to play videos, the fact that it's overheating is either because of poor ventilation or because the thermal paste got dry and would need to be reapplied.

"My Question Is: will a top notch Graphics Card Solve this over heating problem?"
NO. Infact getting a higher end card will only produce more heat in your case. I suspect the issue is that your GPU fan has died, or its clogged with dust and you probably need to re-seat the heatsink with new thermal paste.

I forgot to mention, that I sent my PC in for a thorough cleaning.

Including a new heatsink with new thermal paste (or whatever its' called). This is the cleanest it's been in a couple of years.

Chances are all you need to do is service the 9800gt. Clean out all the dust and clean any stuff out of the fan. If the fan has failed and no longer spins you can get a universal replacement on popular auction sites for only a few dollars.

if service was just done then chances are the heat sink was not mounted properly. Bring it back and have them do it again.

+1, if the issue started after the cleaning then it seems they did a poor job re-seating the cooler. If the issue was going on prior to the cleaning, then a simple card like the ATI 5570 runs cool and has plenty of power for video streaming and even some gaming at 720p.

Yes, the overheating problem occured before I sent my PC in to be cleaned.

(We were hoping the cleaning would solve the problem, but the GPU as shown on SpeedFan continues to overheat)

Meh, thought we had it there. Out of ideas i'm afraid. Could be a faulty gpu. Can't you borrow an other and try that, see what happens ?

ok, just replace the card, but getting a high end card is not the solution, just get something that suits your budget and will run on your power supply.

Just to make sure you're aware of what you suggested, replacing a 9800 GT with a $700 GTX 590: http://www.tomshardware.com/reviews/gaming-performance-...

A monumental chasm exists between these cards' performance. Not only is the difference 3 years of architecture and fabrication improvements, but it's doubled with the GTX 590 being a dual-chip version of a much stronger chip.

You could triple your graphics performance by merely upgrading to a $120 GTX 460 1GB (not the SE version) or quadruple it with a GTX 560--although I prefer the GTX 560Ti.

BUT like stated before this post, getting a new card is not the solution. Let us know if your card's cooling fan spins. See how hot it gets with your case door off. Have you tried any other programs than Speedfan (like MSI Afterburner or HWMonitor)? Have you adjusted your fan settings so that they're high enough? Is the graphics card spaced properly to allow hot air to vent?

EDIT: My dual 8800GT's (same card unless yours is the 55nm die shrink) in a cheap case vent out the side with a single 92mm fan and never exceed 80C). How hot is your ambient?

a 6990 or a 590 won't solve your problems as those generate a ton of heat. They'll probably overheat and you'll have the same problem in another two years.

However, a $15 5450 will stay cool and will play all your movies and TV shows (with the exception that it probably doesn't do 3D but that was never mentioned)

My computer is sporting a integrated HD4200 and it works awesome for HTPC use.

I'll phone the computer repair shop tomorrow and ask them if they have a spare GPU they may insert in my PC and see if that does the trick.

Thanks for the suggestion, I hadn't considered borrowing a GPU until you mentioned it.

I'm going to try these programs and see what happens.

Since I'm not nearly as knowledgable as you, I'll ask the computer repair shop about your other suggestions.

With about two weekends of fiddling with parts, you'll be more knowledgeable than the repair shop. If you're comfortable opening up your computer, you can just do it all yourself and post back here with questions and results. I trust that more than shops so long as you're careful (don't wear socks on a carpet in dry weather, mess with parts while it's plugged in, or break the capacitors off of parts and I think you're good).

The E8400 is a solid enough CPU to where it can handle quite a bit more than a 9800GT if you do decide to upgrade. But I don't think you'd appreciate the ability of any parts pricier than a GTX 560Ti (I don't with my current setup).

How hot does your CPU get when it's idling? Does it use the stock Intel cooler? How hot does it get under load (test with something like LinX http://www.xtremesystems.org/forums/showthread.php?2016... ). Stop tests immediately if your CPU gets over about 70C. Some other people know more than me about C2D chips and may tell you a better temp. I'm curious if your cooling setup is bad or if it's just something with the GPU (9800GT)--that's why were' gonna check your CPU too.

I was just barely able to get these 2 screen shots loaded up into PhotoBucket.com they show readings of my computer at idle.

(*Note - you will have to try to zoom in on them since I wasn't able to get them to the exact size I would have liked).

Well, i'm bit of a noob when it comes to readings like that, but i don't understand why it says you have a 9800gt and a geforce 9300 nforce 730i, both working. Is that an integrated gpu or something ? The temps of the 9800 seem fine, the 9300 are very hot. Also 1.20 volts seem high, but like i said don't know much about this. Interesting though to see answers from more smarter people.


ANYONE ?

There are a TON of anomalies in your screenshots...where to begin...

I assume the 154C readings on Speedfan are just wrong. If they're not, your system will burn up in a couple days. But considering your CPU cores Core 0 and Core 1 are at perfectly normal 29C & 33C, the CPU is probably fine (although I don't know what it would be at on load until you post it). Also, speedfan reports 1.54V for a bunch of the readings. That's erroneous and you'll see the correct readings on the HWMonitor screenshot.

On HWMonitor, nothing is too odd except for the 9.76V reading on the +12V rail. That should read ~12V +/- 5%. HWMonitor readouts are regularly wrong though, so you'll want to see if your bios has voltage readouts. If that 9.76V is accurate, that will cause sporadic shutdowns. What power supply (PSU) do you have? OEM machines usually ship with marginally adequate PSUs that can't handle you adding a graphics card like the 9800GT. If you read your PSU label (inside the case), you'll see how many amps it can provide on the +12V rail. We'll need that number as well as the total output.

Your 50C on the 9800GT looks OK for idle (not particularly good, but not especially bad). The 93C on the GeForce 9300 integrated is odd. I'm confused why that's even running. You should be able to disable it in the bios.

How are your temps if you remove the side door from your case? What GPU temps do you get if you run a stress program like Furmark (use Kombustor on MSI Afterburner)? What CPU temps do you get on LinX (linked above)?

Best solution

I think the problem is there, disable the 9300 and i bet all troubles are over. Like i said ; don't know much about those readings but i do know that's very odd.
He has a cooler master 650W extreme duo btw, should be ok i think. ( for one gpu anyway )

Does the 730i have the pcie 16 lane bridge chip under the same heatsink as the north bridge like on the 750i?

If that is the case then that can explain why that is so hot. Maybe the heatsink on the north bridge is not mounted correctly, or the fan is not working.

I thought I'd remove the graphics card, I figured I had nothing to lose now.

It turned out I removed the PNY 9800 GT (originally cost me $220.00 April, 2009).

I just finished running six 1080p music videos on YouTube simultaneously and my computer hasn't shut down.

The highest temperature recorded by CPUID was 95'C (click on the link below).

http://s957.photobucket.com/albums/ae51/fq283/Computer%...


To be honest with you I was trying to remove the NVIDIA 9300/nForce 730i but i literally couldn't see anything in my PC except the one graphics card.

In any case I just wanted to let you know that the problem seems to have been solved, even if I don't know what i did right?

Thanks everyone,

You cant physicly remove the integrated 9300, it's solderd on your motherboard. You can disable it though in your bios.
Obviously you don't need the 9800 for what you want to do with the pc. On the other hand 95C fot the 9300 doesn't sound ok.
I would try to disable the 9300 and put back in the 9800 or let the pc shop do it if you really don't know how.
