Having problems with your IBM NetVista PC Desktop ?

Some time there is vga signal some time no vga output


Answers :

Though i've been building systems for the greater part of my life, this very problem kept haunting me -- and still does now and then -- no VGA output, though the system appears to be functioning in every observable way. Paradoxically, I still have no definite general solution for this; The two things, I'd like to point out as the most frequent causes: 1. Incorrectly installed memory, whether a broken memory chip or the slot, the wrong type of --; the wrong combination; 2. As dumb as it sounds, the broken or incorrectely connected power button; yes, even though all u need, in theory is the two wires connected two the button set two pins 1 and two [next to the missing one] in the9 pin connectors, still a great many computers require a combination of two or even more, pushed in a sequence for the machine to become fully functional. Plug the power cord to the power supply, -- most likely, u will hear it "revv' up" -- THIS mode of functioning is identical to most "no VGA signal" scenerios; everything seems to be working, but nothing will be operational untill u also preess the damn power-button! Replace that, try to replicate the way the system was initially ingeniered with regard to this. And you will quite likely have solved the issue.
P.S. Don't ever go the so called 'Pro's' in computer servicing facilities. In 99% of cases they'll charge u the huge fee and two weeks later tell u to tresh the board or the whole computer all together, as it is 'beyond [completely not worth it] to try on fixing it. The $100 or so, ofcourse are not refundable. U also stand a great chance of getting intengled in the web of "strongly recomended" or advised special deals, and evey variety of marketing ploy.
