All of a sudden, my computer some times go dark and
says "Invalid Boot Diskette" and next line "Insert Boot
Diskette in A:"
 
Hi,

That error would be expected if a) there is a nonbootable diskette in the
drive when the system is rebooted and b) the system is set in the bios to
boot from the floppy first. To change this behavior, you need to rearrange
the drive boot order in the system bios.

The problem you really need to address is the reboots. They can be heat
related, or they could be a part of a system failure. Go to the Control
Panel/System/Advanced tab, click on startup and recovery settings. Uncheck
the line to automatically restart in the event of system failure. This
should cause the system to produce an error message (blue screen) that can
be researched the next time it occurs.

If no error message occurs, then it can be an overheating problem. Random
reboots are often a sign of over-heating. Things you can do:

1) Open the case and make sure all fans are operating, especially the cpu
fan. While you're in there, get a can of compressed air and blow out the
dust bunnies.

2) Make sure the drive tower is well ventilated and not stuck in some
department store computer desk pc cabinet with only a little vent hole in
the back.

3) Visit a local pc shop and have them add an intake or exhaust fan. This is
not something you should do on your own unless you are familiar with the air
circulation pattern inside your machine. Adding a fan can be
counterproductive if not done correctly.
