    Computer turns on, no beeps, no monitor signal.
    « on: July 20, 2009, 04:25:58 PM »
    I have read previous posts and i know for sure that my RAM is good and my Video Card is Good because i ran a mem test on my RAM and i my video card is brand new. The only conclusion i can come up with is that the PSU is not sending the "Power Good" signal to my MOBO which is resetting the CPU over and over, i know what the problem is but now i just do not know how to solve this problem. How could i fix the "Power Good" signal. Anyone>

      Have you tried the monitor on another computer to insure that it's not at fault?

              When trying another video card in the computer have you disabled the onboard video in the bios?

                Are you connecting the monitor to the correct video card?

                    No, i dont have another PSU atm, which is why im trying to find a solution to fix this PSU before i have to go out and buy a new one, almost positive the problem is the "power good" message malfunction from the PSU which i hope is fixable but i cant find anything on it through research.

                    To avoid needlessly purchasing a PSU you could always take it in and get it checked.

                    If you aren't comfortable checking your own PSU with a voltmeter then most mom and pop shops will check them for free.

                      in the region i live in, the nearest one is about 3 hours away, ive looked into that also, which is why im trying frantically to find a cure for this problem, its happened once before but all i did was take my PC apart and put it back together piece by piece and it worked, tried it this time, didnt do anything. Very confusing problem counting on how i cant even get to the bios screen.  ???

                      I'm sorry man, at this point all that I can suggest is the PSU.  Unless you have a voltmeter to check all of the connections with that's all I can suggest.

                        do you know anyway to reset the PSU to the point where the "Power Good" message will actually get sent?

                        If the PSU is bad then there is no way to reset it.
