299200 2004-12-02 23:13:00 Optimised defaults are a setting selected in the bios.

They ain't a great idea,they don't take into account specific hardware in the comp,and won't set the cpu clockspeed/multiplayer up correctly if its running at a lower setting.

Best to jump into the bios and make some notes,

I would just copy down the settings from each page in the cmos/bios.

That way you can be sure to not loose any of the settings.

Actually, it's very good advice! Leaving it plugged in earths the PC, that's the point of using an antistatic strap if you're not earthed? I use a power cable with only the earth wire connected for this very reason.

This voltage cannot cause any harm to you. It is actually impossible for anything less than 24v to damage/kill a human, and even at 24v you would have to be extremely unlucky (ie. wet skin across heart).

Back to the topic of discussion, it's not smart to leave the power on during this switch. It is also not smart to leave the capacitors charged - these can sometimes cause a similar level of damage as the switched-on PSU can if something gets accidentally shorted. To discharge the capacitors, turn off the switch on the back of the PSU and press the power button on the front of the case. However as other people have said, the case should be left plugged in to the socket - all the switches can be off, as the earth wire is not switched and is therefore always connected while the pc is plugged in.

299204 2004-12-03 01:27:00 Another thought - does your bios have the option to save/restore settings on a floppy disk? Some have this option, and it would save you a lot of time writing down all the settings. If it doesn't have this, you can also get programs that do this for you - they usually run off a bootable floppy disk.

299205 2004-12-03 05:49:00 Re Bios settings curious nobody has suggested looking at the Mainboard User's Manual which has all the default settings. I have made a practice of putting in red in the manual the current settings, most are just a red tick with the odd extra item FrankS (257)
299206 2004-12-03 08:57:00 What a marvellous idea, FrankS! It's usually the ladies who are accused of not reading manuals. In my case, it's probably my age.

Have found manual, so shall do as you suggest. Thanks.

FrankS has suggested ticking off the default settings and making notes of new ones.
