| Well, after so much trouble to make my Ubuntu/Overheating computer work, all it took was trying to replace the heatsink to break it. While I'm getting another CPU to swap out with the current one and see if I can fix it, I thought I'd drill you guys on what happened too; can't have too many opinions.
The computer, in its current state, does the following things: 1. Upon plugging in the power cord and activating the power supply (BUT NOT TURNING ON THE COMPUTER), the power supply makes a continuous, high-pitched noise. 2. Upon turning on the computer, the motherboard emits an endless screech. (Out of the PC speaker. It's like a beep which never ends; is like an alarm.) 3. It does POST; I go to PC health, it yells "94 degrees Celsius' at me like a madman. 4. The heatsink fan DOES turn. However I am unsure if my sucky heat paste job is the cause of ALL OF THIS. I turn it off quickly. Feel free to conjecture what may/may not be broken; I offer this as a challenge to the computer-literate. The processor in question is a 3.2 GHz hunka junk. |

| I had to replace my heatsink paste recently. The original stuff I bought was white, from Radioshack. By a year later, that was eaten up. I then invested in Dynex silver thermal compound and I haven't had a problem in a month. It might be the quality of your paste, or the quality of the spread you did. Just make sure there is a well defined square of paste on the heatsink and it is thick enough to provide a transfer on the whole area of where the proc and the heatsink come together.
Failing at that, I'm a bit alarmed that your power supply is making noises before the computer is even turned on. I've never heard of that. Find out what BIOS your mother board uses and research what the different types of beeps mean. This is extremely helpful in diagnosing hardware problems and has gotten me out of two very confusing binds. I can't remember off hand if 94 degrees C is really hot but it doesn't seem too hot to the point where it would cause serious problems. |

| 94C is about 200F. :p That can't be accurate or else the CPU would've fried. About your problem, maybe try another power supply. A bad power supply can cause all kinds of weird problems. I've also seen power supplies that make noise when they're not on but plugged in. They were usually crappy ones or about to go. (edited by paulguy on 09-22-06 05:57 PM) |

| It really sounds like either a faulty power supply or a short on/physical damage to the motherboard (could easily be caused by screwing something up while changing heatsinks) is causing problems. I've seen various power supplies and similar things (even the AC adapter for the Nintendo DS) make a high-pitched squeal when plugged in, but only when load is applied, so that implies something may be shorted. The squealing PC speaker and obviously incorrect temperature report also suggest this.
I've had two different cases, with two different laptops, where the speaker would squeal the entire time it was on but it would run fine.  Just powering off and on again stopped it. I've also had a desktop do it, but it didn't actually start up. |

| Sounds like the motherboard is the problem. Does the power supply make this noise when disconnected from anything but an outlet? | |||

| No, it only made it when plugged into the motherboard. Alone, it made a different noise; one related to not having a load on it, I believe. (It was a normal whine as opposed to a weird one)
I'm gonna try a different mobo and CPU and see if that works. If it doesn't make the same noises, then I believe it be the motherboard, for sure. Thanks for the feedback, guys--though it ain't over until I manage to get the whole job put together right.  |
