Question about Computers & Internet
I'd have to know the manufacturer and model of your PC to know for certain if this is the case. But based on the information I have, heres what I think happened.
Your 1st symptom sounds like you accidentally adjusted the resolution to something the monitor couldn't display. Which I could've walked you through starting up the computer in "Safe Mode" to resolve. But 1st we have to fix the BIOS setting.
If my theory is right this will be easiar to fix than you might guess. What I think happened is that your Computers Motherboard has an onboard video card. Now if your Monitors cable is plugged into a card in your expansion slots, then its as easy as moving the cable to Another VGA connector by the Mouse and Keyboard connectors, and then go into the BIOS and change that setting back. If you are currently plugged into THAT connector, then it's a little more challenge.
You have two options to fix this situation
1.) Get a video card to plug into your video card SLOT (There are a variety of slots that could be installed, If you have the Manual it can tell you what type. If not Message back here and I can look it up for you. Make sure you get the RIGHT card for that slot) Plug your monitor into that and you should get a display again. (If you borrowed the Vid card from a friend change your BIOS back. If you purchased a NEW card it is likely better than the ONBOARD so leave things as is)
2.) Unplug the computer. Open up the case, there should be a silver disc (Watch battery) on the Mother board. Pull this battery out. Near this there should be 3 pins sticking up with a label of CMOS. There should be a plastic block (Called a jumper) connecting the middle pin to one side. Move this jumper so it connects the OTHER side to the middle pin. Now let the computer sit for an hour. (This clears the settings in the BIOS so they change back to the factory defaults)
After the Hour move the Jumper back to its previous position, put the battery back in, close up the case, plug it back in. Now for the moment of truth, Fire it up and see if we have a display.
NOW that the BIOS is resolved back to the first problem
Boot up the PC just after the company logo disappears push <F8> to bring up the Windows startup menu. Select "Safe Mode" from this list
Once the computer starts in safe mode go into the display settings screen. There is a slider there, for now we're going to set it at a modest level 800X600 (Most video cards can easily display this resolution) Now restart the Computer and you should be able to get into Windows as normal, Where you can set you display to your liking. If the problem reocurrs simply use safe mode to correct it again and the setting just before the one that blanked your screen is Likely to be the MAX that the monitor can handle.
Hope this helps
