After several days in the Seventh Circle of Hell with (now resolved) problems caused by AVG, one of my optical drives has failed completely and I'm suspecting this must be connected to the following, new problem.
When I switch on my Lenovo (IBM) Thinkcentre, a "System is starting... To interrupt normal setup press Enter" message appears - normally just for a fleeting moment, and then the Windows logo appears with the progress bar.
Now, in the wake of the two wasted days recovering from the AVG mess up, POST hangs at the "System is starting" message for what seems like an eternity and the boot only starts after a few candles have been lit and prayers offered. After that, all is well and the system runs even better than ever (a major plus after removing AVG).
Okay... research seems to indicate that this is a BIOS setup problem, but the research doesn't tell me what to do about it. I'm 99% convinced the problem doesn't lie with the hardware - and there is a connection with the trashed optical drive.
Any ideas, guys? In my totally untutored way I'm thinking that the startup is somehow confused by the dead drive.
