When compter is turned on the only thing that runs is the fan. The monitor does not display anything. Can you please tell me what you think happend. Husband took out the power bestec atx-300-12e. and there is a brownish colored spot on it. Thank You

Have you tried with Different RAM and CMOS battery. I will suggest you to try this two thing before doing anything further to your Board.

I think that the first thing you should check is the display itself. Connect the laptop to an external monitor to see if you get video output.
Also, be sure you haven't accidentally turned the video off using the Fn plus special function key combo that switches displays between the laptop and external.

If the Monitor is displaying no infomation at all, your display signal from the PC to the monitor has failed.
1: Check the cable between the monitor and PC
2: If you are using onboard graphics then that display port is faulty.
3: If you are using a graphics card then remove it and try the onboard graphics.
4: Your monitor maybe faulty aswell so test it on another computer to be safe.

Its more likely to be option 2

It mayy be your video card.

you should see the post screen if the monitor is working. try hte fn and the monitor or display key. some laptops toggle the display this way. another possibility is the lid switch that shuts off the display when you close the lid. and it could be heat damage.

if the monitor will match well with Nvidia GTS8800 graphic card, you need to consider two issue:
1) resolution match from windows display property and moniter manu same one.
2) refresh frequency match from windows display property-->advance-->monitor and monitor manu--> refresh frequency
if two side setting could be all matched that you can use normally
if two side setting could not be matched any above step that you can not use some resolution normally possible.

hope help you something fixed, please take a rating let me know how much helped you thanks! keep in touch your question

Try disconnecting the video cable and connecting it again. Turn on. If that fails, you need to try other fix.
Ok, this fix requires to open the thing. Once open:
1) Remove ONE memory stick. Turn on. If nothing, replace the other memory sick and replace the ONE previously removed. Nothing yet?
2) Check if the processor fan is running. If so, remove the processor from its slot and clean the grids of the heat sink and fan, replace the processor and heat sink and turn the PC on.

In fact, that is the troublshooting technique when your computer does not boot up, insert the recovery disk and allow it to reload. The reload shoud be on the screen, otherwise you have a bad monitor and that's a different subject..Now why it happened is what we need to work on..did you do anthing like download programs are anything prior to this happending? Let me know who the re-install goes...since its refurbished it could be anything at this point.. let me know if you have any quesitonsl
Please rate this solution.

hi i am enver parson can you tell me wot tipe of graphics card are you using

You have no display, and cant even get to the bios screen.
OK, does anything at all show on the monitor when starting?
Logo,etc?

If that is the case, look to your video card or monitor.
I cant tell you how many times I have seen pins that are bent or proken on the VGA cable. or even plugged in.
Please check these things and let me know what you find
