MSI REWARDS - PARTICIPATE ON MSI FORUMS, GET REWARDS
Done as suggested - it's back up. Plugged in PC speaker so could use the beep codes on POST. One of the memory modules is kaput. I know this was suggested earlier and although system was never up long enough to run a full memory test I did swap them out, try singularly etc.. - must have used the dodgy module twice, thought it would be something stupid!! PSU was still an issue.Thanks for all suggestions.
