Carputer Woes---just work right!
I need some ideas thrown at me. The carputer has freezing issues and I've been unable to fix them.
Sudden/random complete system freeze, most often with completely corrupted video.
Cannot replicate problem on bench, only occurs in the car.
Most often occurs when going over a bump or making quick acceleration. Doesn't always happen this way, but it happens this way most often.

7200 RPM 2.5" Sata drive
The entire time I've run this PC, and it's been 3 or so years now, I've had issues with the occasional random reboot. Oftentimes it would go for months without issues, so I dealt with it. Literally every part in the PC has been replaced once.
My first M2-ATX killed the motherboard. I had to replace both. I've replaced the hard drive twice---most recently to try to fix the freezing problem. The drive I just replaced returned an "EXCESSIVE SHOCK DETECTED" failure on Hitachi DFT. Upon replacing the drive, the computer would run unbearably slow in PIO-Mode and refused to switch back to DMA until----and this is super random----I unplugged one of the 40mm case fans. If i plug that 40mm case fan into another port, (even if I am not running the other case fan) it also runs slow...so lets forget that fan for now.
The drive, memory, and other components pass a variety of standard and stress tests.
This freezing issue, and it happens pretty regularly, about 50%+ of the times I drive around, is just unbearable. It's a pretty recent problem in terms of the video corruption/freeze. So I pulled the computer out and noticed the M2-ATX had leaking (capxon) capacitors. Blargh---I replaced all the bad caps hoping that would fix the problem. It didn't, so I replaced the hard drive after that.
So, anyone have any ideas? Just throw them at me. It's kind of hard given my very limited budget of pretty much 0 right now to start throwing more parts at it in hopes of fixing it. Sorry if my post seems jumbled and out of order...I'm just really frustrated at this point. When it works great, it runs beautifully. I'm just a little burned out.
