It started about 5 days ago...
My computer would not restart after downloading and installing a Windows Update. After pressing the power button, the keyboard lights come on and there is clicking noise from the CD/DVD drive. That's it, no POST, no fan noise, no harddisk activity, nothing. Then, after waiting for about 5 hours, it starts up normally and without any problems...
Trying to restart the system gives me again the same problem as described above. So, I ran Recovery Console from the Windows CD: FixBoot and FixMBR can not find the c-drive. CHKDSK, does not find any problems.
Then I reinstalled the OS, still same problem.
Lastly, I reset the BIOS, and still no change...
So, the problem is that after successfully starting the system and the shutting it down, my computer won't start up again, unless I leave it alone for about 5 hours, although this time period seems to increase now.
I hope you have some suggestions for me...thanks, klaus
