I'm running Windows 7 Ultimate Build 7600. Yesterday while I was working I suddenly got BSOD for a split second, and I wasn't able to see the error or anything. When I rebooted it could not find the harddrive, so I rebooted once again, and this time Windows was started. It starts rather slow, and when I finally see the desktop I can't use the process bar, or start menu nor see my icons. And it says that an error with explorer.exe was found and that it is restarting explorer.exe, and it just does this over and over again.. I have now tried to restore my system to earlier point where Windows was working properly. I have tried sfc /scannow in cmd in safe mode and I have also tried chkdsk /r none of which helped.. What more options are there? I've tried searching around as well, but with no result. I suspect that this is due to overheating, which is often a problem with HP computers. My computer is not more than a month old though.
