    The problem is most likely due to capacitors on the mobo. Capacitors tend to degrade under lower temperatures.

    Well if it was the capacitors wouldn't my spinrite program have locked up too? I successfully ran spinrite for about 22 minutes on my way to work.

    It will be a few days before I can take the hard drives inside to warm them up for the final test.

    OK here is a quick update. I did the warm hard drive test before it got 60F outside and the computer worked fine. I have to admit that I ordered two of the Gskill 64GB drives before I did the test. I figured that even if the hard drives was not the cause of the lockups I could still play with a somewhat cheap SSD. And if the SSD drives don't function well in the cold I should at least get a little performance boost when they do work.

    Just a note the instruction manual says the operating temp for industrial is -40C to 85C and the commercial is 0C to 85C. I don't know what that means unless they mean storage temperature and operating temperature.

    So I got my drives today and used xxclone to copy the contents to a spare hard drive then used xxclone to copy everything back. That program is the best program I have ever worked with when trying to clone a drive. Anyway I got everything working like it was on the laptop drives. I tested a few things like boot up times and testing to see if I see any of that stuttering people talk about. I set up my drives in a raid 0 with a 64k stripe and NTFS formatted to 512 bytes. My mobo only supports SATA 150 and a max stripe size of 64k for the raid. Boot up times seem to be about the same as the laptop drives but programs respond much faster. Especially RoadRunner with the Digital FX skin. Things seem to happen as soon as you select what you want. The laptop drives you had to wait a second or two.

    As for stuttering I have to say I did see some when I was trying to make it stutter but the stutter was so quick you really had to pay attention to actually see it. You defiantly will not see it for normal car PC use or at least it will not interfere with normal car PC use. Well I don't know about a single drive but in a raid 0 the stuttering is almost non existent. I'm guessing you might see it more if it was used as a normal desktop computer.

    After I installed everything back in my car I found RR would hang for about a minute when resuming from hibernation. For some reason it turn out to be my generic USB bluetooth device. Since I don't use BT in the PC for anything I just decided to leave it out. The only time I ever used it was to play around with the wii remote accelerometers.

    The last thing to try out is cold weather performance. Looks like its going to get down to 29F tonight. So I will report back in a week or if the PC locks up. Which ever comes first.

    With the little time I have played with the new drives I think I'm going to like it. I just cant wait to get two Intel X25-E for under $500 and put them in a raid 0 for my desktop PC.

    OK the PC is still locking up. I first started out by turning on the car and then the PC. I played around with it for about 5 minutes then headed to work. About 5 minutes later it locked up. I turned off the PC and turned it back on. About 3 minutes later it locked up again. Then as I headed back home from work I tried it one more time and it locked up with in about 3 minutes. I left the PC off until I got home. As soon as I got home I parked the car and started the PC again. It ran fine for about 10 minutes. So I thought it might be vibration issue. So then I started shaking the heck out of the PC. about a minute later after I started shaking the PC locked up. So I rebooted again and started shaking again. It locked up again pretty quick. After another reboot it said one of my drives was missing. So I took it apart inside the house and reconnected all the cables. I then started the thing back up and shook the hell out of it for 5 minutes. It has not locked up yet.

    As a test I decided to see what happened if I were to pull one of the SATA cables while I was in windows. When I pulled it XP blue screened. I don't think the SATA cables are the cause of the lock up.

    I'm wondering if it may be a combination of the cold weather and vibration?

    I think I might have to start working on the computer out in the cold to narrow down what the exact cause is.

    sounds like you're well on your way to determining a cause. But what happens when you're in a parking lot just booting up and it happens? What's the cause of that? Stay WARM out there!

    I tried another experiment today. I went to the rat shack and bought some of that canned air. I sprayed a whole can ( up side down to get the liquid out ) over the entire mobo and power supply. I thought that might help narrow down the issue with the cold but the PC kept on going. I'm going to double check the all the wires and put it back in the car. If it locks up again I think I will just give up until I can get some time to actually work on it out in the cold.

    See post #2. Looks like you have a connector or component issue related to vibration. I'd replace the drive cable just to be sure.

    Vibration can certainly be an issue...
    I'd reslot all your cards and memory and maybe dampen and isolate the PC chassis from the car if you can.

    Since I had a few extra SATA cables I decided to replace them just in case while I still had the PC removed from the car. I also hot glued the ends of some cables I cut when I first built the PC just to make sure none of the ends of the wires were touching anything.

    I have the larger Opus case with that shock absorption bottom.

    I did another test this morning. I turned on the car and the PC. I let the PC run and play music for about 10 minutes. It did not even hiccup. Now I will see how it works when I leave for work here in the next few minutes. I also have left my PC laying down instead of on its side like it normally is. I will leave it laying down for this test today and if it does not lock up I will put it on its side for tomorrows test.

    Well the PC locked with in 3 minutes out on the road. I turned it off and back on and it locked up again witn in 3 minutes. On my way home tonight I will try it one more time. Then when I get home I will see if it locks up with the car sitting still.
