Can earth voltage deffect the Main board of a proliant server?

We have a proliant Ml370G5 server which can not stay on power for even an hour.
The technician (not authorized in our country- Iran) told us that the problem is a harmed main board and the source is the earth voltage.
Is that correct?
They've changed the power supplier once but the problem was still there. The server was connected to a UPS and Stabilizer and the current was stable and no fluctuation.
Can earth voltage harm the Main board in a serious manner? We're told to replace the board on our own cost and out of warranty.
Thanks in advance,
Saeed

Re: Can earth voltage deffect the Main board of a proliant server?

speculative judgment
thing happened, however it's possibly from high amperage discharge, take server out from the rack and test somewhere else, swap parts between two servers, if PSU replaced before, who knows it might had some problems and damage passed on sb ?? 1 PSU or 2 ?
