** Description changed: I already asked a question on AskUbuntu but I'm reporting it as a bug as suggested by moderators. - - http://http://askubuntu.com/questions/401283/help-random-reboots-while- - opening-closing-a-browser-tab-or-scrolling-a-pdf - - Above is the link to the question, but I will summarize it quickly: I get lots of hard reboots when the xserver is supposed to do "something" (that's why I call it random), especially when scrolling a pdf (2-4 scrolls will suffice). For example, as I'm submitting this bug, my system rebooted twice: the first time as I clicked on "Yes, log me in", the second one as I highlighted some words with the cursor. I also get reboots while pressing F2 to rename a file (just before the box with highlighted text appears), and also while opening/closing a tab on any browser (right before doing it). It could really reboot on ANYTHING. Here are some clues: 1. If I log into the system and don't do anything, the system is stable and running until I start using it. 2. I'm running a mainstream kernel, but it doesn't matter. A saucy live cd and even a natty live cd show the same bug. 3. It doesn't matter which desktop environment is running. Ubuntu, Kubuntu and Xubuntu are all showing the same problem. 4. It doesn't matter which graphic driver is running: nouveau, nvidia and mesa are all affected. 5. System logs don't show anything, they stop before the crash and restart at boot. 6. A linux i386 (32 bits) kernel DOES NOT SHOW THIS PROBLEM. My motherboard is an Asus A8R-MVP upgraded to the latest BIOS available - and my GPU is a NVIDIA GeForce 9500 GT. + and my GPU is a NVIDIA GeForce 9500 GT. I already tested my RAM for 3 + hours, tested GPU temperature, bought a new PSU and SATA cables, ran + SMART tests, but my hardware seems absolutely fine. I'll try to attach anything that could be useful, but so far my system thinks everything is fine... Please, feel free to ask any additional info.
