Hi, i have a problem with my PC, it is one i made myself about 3 years ago, it first of all the screen would just go black, and a notice in the corner of the monitor said "No Signal" but it would always fire back up immediately, ruling out the possibility of overheating.

Then i started getting problems booting up from cold and also rebooting after it crashed to the black screen, sometimes it takes as many as 8 attempts to boot up from cold or reboot before it boots up fully.

The strange thing is that sometimes it will boot up at the first attempt, other times it does not even attempt to boot up, i can press the button on the case and I get nothing at all, no POST nothing. Other times, it will start to boot up and then cut out just after the welcome sign in Windows XP Home, other times it will cut out shortly after a full boot up and the desk top is visible and other times it will boot up fully and run for hours before suddenly going to a Black screen with the “No Signal” Message in the bottom corner of the screen.

I have tried a different hard drive, with a different O/S Ubuntu installed, a new power supply, a new lead to the power supply on the Computer and a new lead to the Monitor. And still the problem persists and id getting progressively worse, this morning I am lucky to be online at all.
The M/B was a cheap Winfast 760GXK8MC.


My thinking is, that I could have 2 intermittent faults, one being the O/S boot process being corrupt, although I still get the same problem with a new hard drive and the boot up process stops at different place’s or boots up with no problem, and I would have thought that a corrupt boot process, would halt at the same point every time.

And an intermittent problem with the on board Graphix, but I would not have thought that, on board graphics could give an intermittent problem, as there is no connection to come loose.

Thanks for any replies.

My first guess would be the video card. Do you have one spare that you can put in there and then disable the onboard one for testing?

Thanks for taking the time to reply couriant,

I might have a spare graphics card in the garage, but could you tell me how i disable the on board graphics, thanks.

It will be in the BIOS somewhere, different BIOS will have it in different areas, but it should be clear. Usually says onboard VGA.

Thanks Couriant

I see this thread is marked solved... did using a different video card worked?
