Hi and thanks in advance.

I have a dell optiplex 745 - read others on this forum with same issues. I do see at least one cap that is bulging with a tiny yellow stuff coming out so I'm assuming that's my issue. I troubleshooted it this way so please confirm my thinking that it's the caps: will not post - tried re-seating cards with no joy, not one beep (ram) but a buzzing noise. video card works fine on another dell.
fan on psu running and cpu fan so I'm assuming it's the board.

2. read the faq but did not see what size tip I need to use. the station I'm buying...
