For a few weeks I have encountered occasional problems when booting my PC. The symptoms vary so it is difficult to be specific about the sequence of events but I hope that what I tell you will be understood by those who understand these things.
I should make it quite clear however that on no occasion has my desktop failed to power up and once running I get no evidence that there is anything wrong at all.
I usually turn my computer off by going from the Start orb to Shutdown and hear the fans etc power off. When I later press the power button I get the usual single beep and generally the startup sequence progresses as normal. However there have been some occasions when nothing happens and I am left with a blank black screen with no cursor flashing anywhere. If I then press the Reset button on the computer tower this will generally result in a normal start up. Sometimes I need to repress the power button.
I occasionally have the same problem when bringing the computer back from Sleep mode.
Occasionally I have been met with a black screen saying start up has encountered difficulties and asking me to press F1 or F2 (I think) to continue but I do not recall the exact wording. I will note the full text next time I see it and write again.
I wonder if it could be a weak CMOS battery and will replace this soon, but would welcome any comments. I do not want to ignore this behaviour if it could be a sign of major problems, maybe the fact that the PC always starts eventually is leading to a false sense of security?
Should I be worried?
Thanks for any advice, best regards,
