Hi:\n\nI am about to kill myself!\nWe have a server running 2 Xeon SL622 CPUs on Tyan Thunder i7500. One\nday when I was installing a new video card, trouble started to break\nhell. It took the computer 3 minutes to post after I powered it up.\nAfter I uninstalled the video driver, the computer woldn't even post.\nWhen I opened the case again, I found one CPU fan stopped working. I\nthought maybe the mobo went bad OR the CPU was fried. I decided to\norder two new CPUs and a replacement mobo (we have good warranty\ncontract). With the NEW mobo, new CPUs, old PSU, the computer still\nwon't POST! AND NO BEEPS! I thought maybe the PSU went bad too? So I\ngot a new PSU, AGAIN! The same thing. I am trying to find out why there\nis even no beep because clearly on their manual says beep codes for\nerrors. There is only the J22 with 4 headers which seem to be remotely\nrelated but I have NO idea what to do to have the onboard speaker to\nwork. Isn't this supposed to be default???\n\nAnyone please?\n\nThanks in advance.
