Strange hardware/software issue, hope this is the right forum!!

OK, here goes,

I have been running Slack very successfully now since 9.1, during which time I have upgraded to 10 --> 10.1 and to current. Running a self compiled kernel 2.10.6, kde 3.4.1. latest Nvidia drivers.

During all of this time, aside from one or two small issues, it has been a very smooth ride, and those small things were always able to be sorted out by a visit to this forum. But now I have a really strange thing happening.

Let me explain, a month ago I bought a samsung DVD +- RW drive, and installed it in the place of my currently (at that time) DVD reader only. Since then my machine crashes , or rather the Xserver crashes, and renders my box unusable unless I ssh into it from the laptop. Niether the Xorg logs, nor the system logs show anything out of the ordinary, and there is no repeatable pattern to the crash. Somteimes it will happen on login, other times the PC will run for hours, other times for only minutes. The longest uptime so far since the installation of the drive has been about a day and a half. It also makes no difference what apps I run, as sometimes it crashes when idle, while at other times I can be streaming audio from the net, while using OOo, Amsn and browsing the web at the same time.

I have no irq conflicts, the new drive simply claiming the same irq as the old one, and other than being a writer, is pretty much the same spec.

I have determined that by disabling the graphics drivers within my Xorg.conf file, the PC runs as well as it ever did, and only crashes when the Nvidia drivers are enabled, so I reverted to an older version that I new had been running on my box for the last 6 months without drama, but the crash still happens.

Now you might conclude that the DVD writer must be to blame, which is the conclusion I came to, so I removed it and put back in my old DVD reader, set the box up to the latest nvidia drivers and everything seems to be fine.

So I tried the DVD writer in another machine, and guess what? no drama, no crashes, it works really well, put it back in this machine, and once again crash upon crash.

So, what is going on, can anyone give me a clue what to try next, as I am well and truly out of ideas.

I'd try a kernel instead of the 2.6.10 (i presume that's what you meant).

Something about nvidia drivers IMHO
Some test to do :
- in bios set agp fastwrite to off
- in xorg.conf try add option NvAgp "1" (or "2", at least "0")
- did you set framebuffer value in lilo.conf ? if yes try vga=normal

Thanks for the spot on reply. Adding NvAGP "1" to my Xorg.conf file has done the trick. I still don't understand why this has only happened since fitting a new DVD writer, but as it is now working, I am not going to waste anymore time on it, besides which. it was giving me a headache just thinking about it.
Once again, thanks.
