Finally solved all computer problems, where nobody else could. After having Infoman have a look at my PC they said it was a virus, and it was repaired, but the problem (sudden reboots) kept occurring. In addition, my DVD player didn’t work anymore. I opened the case and found a dangling cable end, almost touching the motherboard. I think when the fan started blowing, it would sometimes short-circuit the MOBO (it’s a guess still). Anyway I secured it and the problem is now gone. 2 weeks, no reboot.
The broken CD player was a problem with an application named ‘HotSpot Shield’. Actually a pretty good app that enables you to access all kinds of sites that are blocked in your country (e.g. Veoh, Hulu, some YouTube vids). But, the thing came with very annoying ads so I uninstalled it. A couple of days ago I bought a wireless router and setup a network. All went well, but the connection dropped suddenly. I checked the TCP/IP stack and saw ‘Hotspot Shield’ as a layer in there. Damn! I said: “He’s the guy”.
Here’s what happened (Adrian Monk style): “At first we thought it was maybe a virus causing this, but cleaning with plenty of scanners didn’t resolve it. The next suspect was the hard disk, but even chckdsk /r didn’t solve the problems. Then we suspected the drivers themselves and reinstalled and updated all drivers. That didn’t work. But then we found HotSpot leaving a trace in network settings. Hotspot Shield needed to intercept all traffic in order to make sure it looked like it was coming from the US. So it put itself not only in Program Files, but also as an add-on in browsers, and as a layer in TCP/IP. That interfered with the built-in modem driver, which then failed. The modem driver looked for another resource and used one that conflicted with the DVD drive. After removing HotSpot from all network settings and uninstalling the DVD driver, it came back automatically and started responding again. Patient saved, and HotSpot put away.”
