POST Problems - 20 Beeps!

[dakine1972]

Having intermittant power issues, and it seems to have corrupted windows. So I was resetting windows when power went down again, and it is now corrupt.

But my question is, now to try and repair the installation the PC beeps 20 times and does not complete the POST. Because of that, I can't use a windows install disc as it wont get past post.

Anyone have any ideas?

Hi

20 beeps is unusual, you quite often get a beep code repeated 5 times, so could yours be 4 beeps repeated 5 times?

Depending on the age of the PC and the BIOS vendor...
