    I'm going to try that. I just got home and it was still running from last night, but it crashed when I went to shut it down (same thing it does in the car). Back to the overheating hypothesis I guess. I'm going to try to attach an old amd athlon thunderbird heatsink and fan to the heatsink on my laptop and power the fan from the carnetix psu 12v output. I'll see if that works. Just have to figure out how to mount it.

    Alright, got it mounted but without the fan. The cpu was running around 75 degrees Celcius. I don't know if this is too hot or what, but it turned off. Guess this laptop is just a goner. I may just invest in a new one next month. Very frustrating.

    I think it has a short in the motherboard somewhere. Oh well. I guess I need a new laptop.

    Try swapping out the memory. Memory can make the laptop do wierd things. Also, if you have it aprt, check the capacitors for signs of damage, like leakage and expansion. That can also cause the thing to act "wierd"

    OK, I took it apart and swapped both memory chips for a single kingston 256 SDRAM. It still did the same thing, so I took it out of its plastic case and plugged it in (of course w/the hard drive and floppy attached) and it seems to work flawlessly. Especially when I stick one of my cooler master 12v fans over the heat sink in place of the existing 5v fan. Chip stayed cool and it didn't crash. Ran it for almost an hour in the car that way. I think I'll leave it out of its case and mount it to a piece of plexiglass or plywood in the trunk.

    no, we are looking at an overheating problem for sure. Memory wont cause the Pc to shut off during use.

    Your problem is lack of conduction. try getting some acrylic silver thermal paste (not glue because you wont be changing your CPU anymore ) glob it up real good and make sure the CPU fan or heatsink are on there tight. If it has clips try bending them to get it lower.


    this is a common problem with the AMD Turion 64 chips. These are based on the 754 socket. you can put a mobile chip in a desktop 754 board BUT the mobile CPU is smaller than the desktop CPU so there is a lack of thermal transfer. Zalman makes CPU fans that come with their own brackets (you take off the stock CPU fan holder and use theirs) and they work.

    it is a bit off subject, but that is most likely the problem.

    Is the acrylic silver thermal paste just like the stuff they sale at radio shack? I have some heat sink compound from there. It's white. I used it sparingly on the cpu b/c I did know if it would be good to get extra on it. I put a dot in the middle of the cpu and installed the heat sink. It seems to run better when I use that 12 volt fan turned on constantly to keep the cpu cool. I'll check out zalman as I've never heard of that brand before, but it seems to work with a better fan. Thanks!

    UPDATE: Ran the computer about 2 hours in the car today, and it worked beautifully. No crashes or anything. I used centrafuse to check the cpu temp a couple of times and it seems to be hovering around 55 degrees celcius now with the fan constantly circulating the air.

    Thats good to hear.

    I should correct myself, it should be called Arctic Silver and it is similar to heat compound you find at Radio shack but it does 10x better of a job. It will cost you around $11 for a tube of it but you'll get 2 or 3 uses out of one tube.

    You can buy it at your local computer store or order it online but after shipping it comes out to be the same price.

    NO!

    2 or 3 uses ? you must be JOKING?!

    You should only use a VERY small amount of Heatsink compound!

    It has to be such a thin layer it's almost see-thru, it's so wrong to GLOB it all in, and tell other to do it.

    A single tube of AS Compound lasts about 50 CPU's or more.

    Apply a small drop and level it out with a credit card or the like, and you're set.

    NOTHING transfers heat as direct contact does, AS compound is a bad conductor of heat, but better that air (air isolates)

    hey, he's right, the only reason you use compound is because the 2 surfaces can never mate perfectly on a microscopic level, the compound is just to fill microscopic voids & allows more heat transfer than the voids, if both surfaces mated perfectly then no compound would even be necissary...
