I've done some researching on this notebook, it so happens that the Dell Latitude 610 (I had one before, and was refunded per warranty) has MOBO problems. Many of them, over time, develop fine cracks in the MOBO. Over time, this leads to BSOD's, one of which I just recovered from (in Vista). I only allowed the DBAN process take two rounds, as it was going to take a week for it to run 35 times.
Since recovery, the problems are getting worse, rather than better. I restored all partitions with Acronis, done a check disc on each OS, and still am having problems. The only one that I can narrow down is a heat issue. Acronis has a free drive tool that checks your drive(s) health. As I've already said, I just recovered from a BSOD in Vista, XP has crashed twice, Windows 7 is crashing, only Win 2K is running decent right now, which come a couple of weeks is going to be dropped my MS.
These were all fresh installs less than a week ago, except 2K, I recovered it with Macrium. I've done everything that I can, except just trash Windows and going with Mint on it, except the 10GB where 2K resides, I don't want to get rid of it. I suppose that I could install Mint, then run 7 Pro & XP in Virtualbox (Vista will never run in a VM on this notebook).
But one thing that I haven't done, but have the download for, is to flash the BIOS. I guess it's the latest version, that's what shows on Dell's site. I have it on a flash drive. However, I feel that no matter what I do from here, it's going to get worse. That MOBO issue is the key here, as I've had this same notebook before, and when the BSOD's started, within a month, it was over. It so happened. Shit, here we go again, another BSOD, and I caught a glimpse of it this time, it said something about "not less or equal" then shut down. I started it right back up. It's either going to run or die, and I don't care which it does, as long as it does one or the other.
Thanks to all for your advice, but I personally feel that the end is near, it was already giving some trouble, now BSOD's, folding at 100% CPU, too. I'll just keep an eye on it, if it shuts down, I'm firing it back up.
I believe my new notebook is around the corner.
