CPU temperature problem when installing Ubuntu


Trying to install Ubuntu from CD. I choose my language and hit Install and come to a black screen with the Ubuntu symbol glowing (loading everything I assume) and after a minute my screen fills up with messages saying my CPU Temperature is 99 (gets progressively higher) degrees...

Is there something else I need to do before installing?

I have windows installed on my C drive and I'm planning on installing Linux on another blank drive. The Ubuntu version is the newest one (9.10) I think.

I've got a Core i7, EVGA mobo, Nvidia 9600GT video card, and 6 gigs of memory. HDDs are all WD I believe, and the one I'm putting Linux on is 320 Gig.

Any advice or a way so solve this?

Which Ubuntu are you installing? The 64bit or 32bit version? With 6Gb of memory I would suggest the 64bit version.

Check your motherboard options and system state and ensure that the cpu fan is running and not set to any special variable speed settings that require motherboard drivers to function correctly. I would also ensure my heatsink was fastened correctly.

How do I check my mobo options and system state?

and I am using ubuntu-9.10-desktop-i386 when I try to install, so I might have gotten the 32-bit version. Where can I get a 64-bit version?

Since you have it running under Windows, the chances are that nothing is wrong. It may be that Ubuntu just doesn't like some reading it thinks it's getting from the temperature sensor. You might try a different distro.


Original:
Bring it up to BIOS state. This usually means holding the "Delete" key down when you hit the power on button. Then, find the place where it displays the various temperatures and voltages. Monitor that for a bit to see how high the temperature actually gets. It shouldn't get much higher than that during the install procedure. Check to see if there's a way to turn off temperature monitoring. Make sure any temperature related alarms are turned off. If you're overclocking, don't do it. If you have any voltages deliberately set high in the BIOS, set them back. In fact, consider just pressing the button that sets everything to default.

Are all the fans running? Especially the fan on the CPU?

Exactly which motherboard did you get? What brand of heatsink did you get? Did you build this yourself or did someone else build it?

Nevermind on the 64-bit. I figured it out and it's downloading now. You think that might have been the problem? My friend suggested I run a CPU temp program and see how well my computer does with 100% load for a little while. It's not making any weird sounds or getting hotter than usual so far. I think I'll stop it at 1 hour and then give the 64-bit a try. May take a while to DL it though.

Oh, ok. I'll check that real quick. I'm downloading the 64bit version on my laptop so that might help as well.

My friend says my temp sensors are screwy, cause they are always at 84-ish. Maybe I can reset them and they'll work, if not I may need to check for a bios update or just turn them off.

Dude! That is ultra freaky! My vote is that it's a HW problem unrelated to linux whether 32 or 64 bit (CPU fan died, etc.), but PROCEED WITH CAUTION regardless!

If it is a distro making your CPU burn up, I'd love to know exactly what's going on there.

Keep us posted if you can because that's just psycho (to me, at least).

Regards,

Rick

Ok...it was a problem with my CPU fan not being securely down in 1 place. Once I blow it out ant put it back on snug my temp started reading 30-35ish. I think this fixes the problem. I hate those stupid things that you clamp into the mobo with for CPU fans. They never work right...why can't someone make one with screws or something?

Anyway, still got 2 hours on Ubuntu 64-bit (unless it is better for me to install 64-bit) then I'll burn it and install.

Thanks for the help guys. You may not have had the exact answer, but you pointed me in the right direction and I found the problem.

Hopefully my next post will be from a Linux machine, hehe

I've not been a bit fan of just converting to 64-bit for the sake of doing it, but since this is a new install and you have so much memory I'd say go for 64-bit. It is the way forward, and will save you having to do a complete reinstall when/if you run into a need for 64-bit.

I tried the 64 and 32bit versions but I keep getting to the same screen and I get a weird screen of text and my screen goes blank. This is right after the black screen with the white ubuntu symbol in the center.

Anyone else experience this?

No, to be honest. I'm trying to remember what the first screen I saw when I last installed (I've only done 32 bit and it was around a week ago), but I'm not positive.

I think it's a text based screen with a box in the center waiting for you to select an install option. IIRC, there's a timer ticking down the secs that you need to abort by hitting up or down arrow keys. By stopping the timer it gives you unlimited time to read the various options like:

Fresh Install
Upgrade
Boot from Live CD
etc.

If you're seeing the white Ubuntu symbol, your system should certainly be able to display the menu screen I'm trying to describe.

The only thing I can think of is to search for a way to force a common video mode on install like 1024x768 or, failing that, force a text only install and see if that at least gets you farther along.

Wish I could be of more help!

2nd thought... quick sanity check.... boot back to windows if you can to verify the HW works OK.
