Comment 13 for bug 337351

Hello. It's the first time I post here. I've been having this problem since I upgraded to KDE4. I've posted this problem in many forums and nobody has given me a solution. I just have little differences in my description, but it's basically the same thing you have posted.
 My computer freezes at any moment. And it's a "full freeze". The mouse and keyboard are dead. I notice that the fan coolers work a bit harder, but I've left the "top" command running on the screen and I see nothing running at 100%. The strange thing is that after a few minutes (could be 5, 10, or more), the system comes back to life. When it happens all I can do is push the reset button in my computer... or wait until it comes back.
 This never happened when I had KDE3 (with kubuntu 6.06). It all started when I moved to 8.04. Right now I have Jaunty with kde 4.2.1.
 On windows I have no problems at all. Which makes me use more Windows than kubuntu (frustrating, yes).
 Important: I have a dual boot configuration (WinXP & Kubuntu) using 2 hard drives (80GB SATA for windows and 30GB IDE for Kubuntu). This is the rest of my hardware:
 Pentium 4, 3ghz (with intel motherboard); 2GB RAM; NVIDIA 7300GT (256MB); SBLIVE 5.1; I have 1 optic mouse and 1 ps/2 keyboard.
 I've done several tests. Did one with fdisk and it said I had 0 bad blocks. I have 1.2gb of Swap memory, but always "0" used.
 And yes, I have the latest nvidia drivers (180.51). Of course I tried all the previous versions. It happens with/out the Desktop effects. I'm not sure it has anything to do with drivers... After my latest re-install, it didn't take long to get freezed. Even before I installed anything. Even before I updated the system. Just fresh-clean installed.
 It happens when I'm playing games, when I'm surfing the net, when I'm doing nothing.... or it may not happen at all in one night. It's totally random.
 Another strange thing is that, when the systems comes back, the computer clock is delayed (for the amount of time it was freezed).
 Any idea will be appreciated. I'm running out of options.

 Greetings,
 Eric.
