For no apparent reason, at seemingly random times (even when I am not using the computer), the screen will go blank and return, I get the display driver has failed and has recovered type thing. This will happen multiple time one right after the other until a blue screen pops up for half a second and then my computer completely powers down. I can pause the sequence once its started by pulling out the cable to my other monitor. 2 things happen now. I can exit Ultramon, plug the monitor back in, and have it appear correctly, continue its series of display driver failures and then shut off. Or I can leave ultramon on, plug the monitor back in, and get a jumbled mix of things on my second monitor. I believe its a failed mirror image, because as I change things on my primary, the secondary will shift slightly. I can fix this by going into my ATI driver control panel and enabling the second monitor. It'll return to normal extended view, fail a few more times, and then turn off just like before.
I'm using a dell studio 1535. New. Radeon HD 3450. up to date drivers. its doesnt happen often. i believe the driver that fails in the alert message is atikdiag.

Which version of UltraMon and Windows are you using?

Most likely a display driver issue, maybe it gets triggered by something UltraMon does, but this seems rather unlikely.
I would recommend reporting the crash to ATI. If you want to verify if the issue is related to UltraMon, try if you still have the problem without UltraMon running or installed.

I also have a studio 1535 with a ATI Mobility 3450 card.
Mine crashes almost every day at least once or twice running an extended desktop onto a standard lcd screen.
no use at all in contacting ATI, as they arent allowed to support dell machines. Dell restrict the ati support so you have to wait for dell to release a driver update anyway.
I have no idea how to fix mine crashing. any ideas?
I am usually just running word and outlook, no even graphics intensive stuff.

I'm not an Ultramon user, but I have had exactly the same crashing problems with a Dell Studio 1535. So far Dell tech support have tried several things. They took control of my desktop to install most recent driver. They sent an engineer to replace the motherboard. They made me reset to factory delivery condition. Problem was still there, so they replaced with a Studio 1537 of similar spec. But the problem on that is still identical, which isn't surprising as all the studio laptops have same ATI card and driver. Only thing left seems to be to ask Dell for a refund. I don't think this is an Ultramon problem.

Its the display drivers getting stuck in the driver caches on the mechine. Its really hard to get rid of the errors, but you can. It requires manually uninstalling the drivers completely, every last trace of them. security complicated matters of course. The link below is for nvidia drivers, but it will be the same process for ATI drivers, just a differant dll file.
