Hi and welcome to my blog,
I opened this blog to help anyone who is preparing for his SAT.
I remember myself when I started - I was so lost and in such a panic.
Luckily I got this great SAT guide that helped me a lot . So study hard and good luck!
i got a free dell cpu from my friend today and bought a 19in crt monitor from used computer place () (monitor is also dell) they gave me a cable with it but i am only getting the "MONITOR WORKING" blurb on screen when it is turned on.the cpu was working yesterday ,i suspect cable or my stupid behind is hooking it up wrong! i have a laptop too is there a way to use laptop to test cpu function

No you cannot use the laptop to test the CPU, but you can connect the monitor to the laptop and see if it can turn it on. Unless you have more than one monitor plug on your computer (such is the case if you have a video card built into the motherboard and are using an add-in video card) then you cannot connect it wrong. The plug on the video card is a 15 pin dsub and while that may not mean much to you, it means that it is D shaped so it can only be plugged in one way and it has 15 pins or wires (up to 15, some have less)
best to have the monitor tested by a professional
well if it’s powered on and you get no signal from the cpu (provided it’s hooked up correctly), then it may be yoru video card that needs to be replaced
If the pc was working on another monitor and the newer monitor fires up, I would suspect the connector has a bent or broken pin. It may also be that the pc is simply too old and isnt compatible with the monior or vice versa!
not really
you are better off hooking up the monitor to an existing pc/monitor setup and swapping out parts til you find the bad one, first monitor, then cable, then video card
also if the Dell is finishing POST the ABCD lights on the back should be all green, if they are not msg me
