I know I've asked this question before but I'm not very sure of the answers that I got back. I know most of the responses said the video card may be bad but I have no idea how to check that! I've unplugged the monitor from the tower to see if it still had the same message and it did. The computer is hooked up to a wireless hookup of which I remember when the computer guy first hooked us up the computer did the same thing. He took the computer home and called me a few hours later saying it was fixed but wouldn't explain what was wrong. I don't want to take the computer back to him as I sai before because after I got the computer back and did a virus scan I found the blaster.32 virus on there. The computer has been extremely slow since he worked on it but I thought it was from all the pics I had on there. I've cleaned everything off the computer but now it will not boot up.The screen is completely black but with the red box error message "No Sync"  Please tell me what to do!!! Thanks

Did you pay him to fix it? If you can try another monitor from friend to check out video card to see if that the problem or not. You can start there.\n\nFollow the one thicker cable down to the back of the monitor to back of the computer tower, when you get to the end to should be a blue or black plug  on it, will had two thumb screws, that is your video card, double check that plug is seated in the card good, is the light on monitor green or amber (yellowish orange color)\ni don't think the wireless hookup has to do with anything with the monitor.\nI do recommend trying another monitor just to see, be a good way to find out which way your going to have to go,

If all you get is a black screen then how do you know that your PC doesn't boot?  It may be booting.  Check cable connections including power.  Is monitor turned on?  If all checks out then check computers setup using appropiate F Key (varies depending on brand and model, see manual).  If still black then try another monitor.  If problem persists then the problem may be your card but most new PCs have the video card integrated on Motherboard and if that is your case, then more than likely, depending on age of PC, it is better getting a new PC then fixing it.

Try the power settings on your computer. \n--or--\nif you have another pc, try connecting the monitor to that\n--or--\nupgrade your OS. ME is the worst OS by MS.

go to device manager from control panel, control panel>system>device manager>display adapters and either rinstall driver or rollback driver. If that doesn't fix it, the in graphics properties, change you monitor driver to plug and play. that should fix you up, if not, email me if you find any other problems and I can talk u through them

We had what we thought was a dead monitor at the library I work at.  Turned out that the vga connector into the CPU was loose.  The tech jiggled the connection and the monitor came back on.  Hope I explained it correctly.

I was in your problem 2 days ago, and the VGA card was not connected proparly, I opened the case, connect the Display adapter well and start, and hey everything is going to work again.

It could be a couple of problems. It could be that the processor is overheating and you might need to get a new fan or reapply the thermal glue. It could be a bad power supply or power supply cable. I don't think it is a virus for the simple fact that even the deadly boot sector viruses show signs after it does POST. I would take it into a computer tech shop or the Geek Squad and find out what they say. Good luck.

if u hav a AGP graphics card then it could be heating up... happened wid me... or there can also be a virus attack.. the rest a hardware prob in monitor or curcuit prob possible.

This is extremely odd as in all my years of servicing computers as a technician, I have never heard of a computer screen going black because of a system restore. Lets see, go through a basic check up first.\n\n1. Turn on monitor, attach the wire to video card.\n2. Make sure the contrast and brightness are set properly.\n3. Move your mouse and press ENTER and ESC on your keyboard exit any possible hibernating states.\n\nNow for troubleshooting...\n1. What caused your computer to need to get system restored in the first place? If it is a virus, it might be the cause of this problem and try turning on the system with your system boot disk or windows disk (however this is usually very rare).\n2. Ask yourself, is the system on and running and do you hear the normal beeps and sounds that the pc normally makes when it is booting? (If the answer is yes, then this problem is usually not a software problem as things are running smoothly, it's just that nothing is showing on your monitor. Try getting ahold of another monitor and see if that works. \n3. What color is the monitor's power light? (Usually it is green or orangish). If it is orangish, that means your computer is not recieving the signal from your computer system.\n4. Wait for a few minutes and press ENTER / ESC every thirty seconds or so. If nothing happens, after about 2 minutes or so (about the time it takes the pc so turn on, press ATL F4 and Enter a few times. If the PC turns of, that means it has successfully booted and you definitely have a hardware problem.)\n\nIf none of these solutions worked, feel free to email me at bqm1234@yahoo.com as I am quite interested at what is causing this problem and we can sort it out from there.

Is there *absolutely* no power? No orange light even? Maybe the power outlet you're connecting it to is faulty.\n\nIf you're getting the orange light, it might be a video card problem.\n\n==============================================\nI hope you see this, because I couldn't email you because your ID isn't confirmed.\n---------------------------------------\nRe: No Power TO HD Monitor\n\nAh, i didn't read your question properly.\n\nCheck the power pins on you old monitor. The place where you plug in the power cable on your monitor.They might be covered in black sooty material if something blew up. \n\nOr maybe the fuse inside the monitor is blown. If you can open it up and check that out, and that IS the problem, you can get it fixed for a few $s. For less if you have the equipment and know how to solder.

Too vague. It could be a ton of things. My first guess is not a virus because it isn't happening all the time. Since it happens to be mostly when you are playing games my first guess would be your video card. Make sure that the card you are using matches the specs of the games you are playing - then update all the drivers for your current card and try again. If that doesn't work you might need a new card. It also could be memory. Try adding more. Your computer also could be running too hot so it turns itself off to prevent damage. Are all of your fans running? Check bios to see if your temperature is normal. Blow a high powered regular room fan on it while you are playing the games and see if it turns off then. Could be the power supply too. There are so many things. If this all sounds too daunting bring it to a tech or best buy and they can fix it for you, but they'll charge a ton and probably just tell you to buy a new computer from them.

as above - the best place to see if you have a hardware problem is to see if the screen is not centred when you access bios \n\naas bios works out side of windows it will tell you if you have a hardware problem\n\nIt is most unlikely that you have a driver issue as you can see a display though the crt monitor\n\nalso trying safemode - usually pressing f5 on startup - try using safemode with vga - \n \nif you have windows xp - you can also uninstall the display adaptor within the dev manager - when you restart windows it will reload the default device drivers for the adaptor -\n\n\nis your graphix integrated or a separate card - if it is separate the above may work\n\ntry all above and if you still have problems it is most proberly a hardware fault \n\nhope this helps

Is there anything on the monitor when you turn it on or is it just completely black?\n\nIt could be a number of things. It could be your fan or your connection or maybe your RAM is damaged. Normally if your hard drive or memory dies, you would not be able to turn the computer on at all or you get a message on your monitor saying an error occurred trying to read your drive.\n\nI have an emachine too, I usually do my own fixes, but I would open the motherboard up and watch what the circuits are doing when you try to turn it on. If you had a short circuit from a power outage and you dont have a surge protector, then its possible it damaged your hard drive or your memory.\n\nEDIT: Yes, 4 years is usually the lifetime of a desktop computer, especially an emachine. You will have to take it to the technician and figure out whats wrong with it because I read the other DETAILS and it sounds like your hard drive has fried or some part of your motherboard has been damaged. You will need to install a new hard drive. Normally when your hard drive gets fried, the data is not retrievable. A technician can tell you whether or not they can save the data, but it will cost you A LOT trying to recover all your data from your hard drive. You should always backup any important data every few months to a CD-RW in case this stuff happens. A computers lifetime is very random, but 4 years is usually when something goes wrong.

If you don't even get the dell splash screen after replacing a video card, I would try reseating all the power cables going to the mother board. If you still get no video, then maybe you can get a pci video card to use just to get by. Make sure your following ESD procedure when installing parts (you might be frying the part before it even gets into the system).

First I would strip everything off your motherboard.  Remove all extra PCI boards and extra memory etc.  Remove all your USB/serial cables and stuff and go into bios and select setup default (not performance).  Start your PC. If it does it again try another stick of memory in place of the one you left in.  If still a problem it sounds like a virus and if you reinstall Windows XP using fdisk make sure you c:&#92; format /u as the virus might be in yer boot. \nIf the problem is resolved by removing items it maybe your power supply not coping or on its way out or one of the components removed is faulty.  So put stuff back on your board one at a time and start PC to find the problem device.  As you load your board up the power will be drained so the fault may occur.  So make sure you swap your PCI boards around before slinging it in the bin to check they are OK because it might be the power supply.

This may be your video card going bad.  If there is a fan on the video card, make sure it is free of dust and operational.  If you have access to a different video card then try that.

download the current driver for your video card. if that doesn't work your monitor or video card might need replacement. Also try to degause your monitor if its not a plasma screen.
