Lost connection

I play online bingo and find that after a short time sometimes only 40mins my
connection just dies even though it shows me as still being connected.

I've tried countless times to empty tem internet files but this doesnt seem
to work. I have a feeling my computer may be too old to run the software
they are using. I have an antique P3 450 with 128 ram. The software is
macromedia based. I can play at yahoo for hours with no problems but these
sites just dont like my computer. Is there anything (apart from updating)
that I can do?

Thanks in advance.
