Graphics and/or moniter issue

"My old moniter the one that has this problem works but for this issue which is random and comes from a old dell dimension 3000"

OK. Your monitor comes from an old Dell Dimension 3000, and "works" except for this random problem? Do I have that right?

The orange light would normally indicate no signal is being received.

What happens next? Does it just come back on? Do you have to power off? Reboot? Anything else unusual happen?

If the PC is still "running" when the screen goes blank, the problem is likely the monitor or vid card. If its not running or frozen, the monitor is NOT the problem.

- How do you reboot the PC after a failure?

- When did you build this computer?

- Did it always have these random failures?

- Do you have any other parts available to you, ie, another vid card or psu?

Since we're now forced to guess . . . if a simple reboot gets info back on the screen, the problem is not likely to be the monitor. I can only think of one other way to try to narrow the possibilities.

If you have or can download Prime95: Do a fresh boot then run a stress test without changing screen graphics. If the PC fails during this test, I'd guess its less likely to be the vid card, and more likely the psu.

Then I'd replace the psu because even if I were wrong having a second psu around is, as you can see, not bad idea.

Sorry I can't be of more help, but its a parts swap or guesswork from here for me.
