Monitor doesn't start when computer boots

Q: Monitor doesn't start when computer boots

I'm kind of stuck here...

First what happened: last night my computer froze so I turned it off and then back on. However, when I did, the monitor just remained in standby as if the computer was not on. Everything on the computer seems to be working ok (fans going, lights on, etc). I also don't hear any beeps during the startup.

I've been browsing a lot of forums trying to figure out what is wrong, but I'm somewhat lost. I don't know that much about computers...
It seems some of these forums say the main culprits for a problem like this are the graphics card or the motherboard? Is this true?

Since every thread always has someone asking for specs - here they are:
Intel i7 940
Asus p6t intel x58 chipset sle/crossfirex mainboard triple-channel x
800w power supply
1 TB SATA II 3.0 gb 7200rpm HD
3 x 2GB DDR3 PC3 PC1333
1 x EVGA nvdia gtx 260 896mb pci-e
windows vista home premium

What I've done so far:
I have tried unplugging it and holding down the power button in the front for about 1 minute. 90% of the time this did nothing. One time it started to boot correctly with the monitor only to freeze during the windows load up bar and 1 other time it didn't even make it that far...
I have tried using another monitor on the computer. Same problem. I have also tried using my main monitor on another computer and it works fine.

I have been running this setup for almost 2 years, and nothing has been changed recently...

I would greatly appreciate any help in determining what is actually the problem, and maybe a way I can fix it. Even a "____ is broken, get a new one" would be nice too. I just want to understand this a little more about what is happening since I know very little. And I also want to know how I can have a running computer ASAP.

Also...is there any way to actually tell if my computer is running properly if I have no monitor to see stuff on?

Thank you very much!

Preferred Solution: Monitor doesn't start when computer boots

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I've been fighting this problem for months and haven't found an answer anywhere but maybe you guys can help. My computer seems to boot fine, but nothing is displayed on the monitor. The power light on the monitor ON button just blinks amber. If I wait a minute or so and then hit the reset button the computer reboots and the monitor comes on. The computer started doing this about 6 months after I built it. Once in a great while it will boot up on the first try, but it's very rare. I was thinking video card, but have unseated and reseated it a couple of times to no avail. I also got a new battery on the motherboard thinking it was having a problem. Now I'm thinking power supply or BIOS - any ideas?

2.8Ghz Intel p4
Radeon 9600 pro
ASUS p4p800 MB
1 GB of Micron ram
QMAX 350W power supply

Thanks in advance for any help.

Hi Tech Support Guys and Gals,
I was using my Hp laptop and the screen randomly froze. I manually powered off the computer and now when I turn it on, I hear one longer beep followed by two short ones. In addition, the screen doesn't work. If I let the computer keep working and boot up, I eventually hear the welcome screen theme play so it seems like the computer keeps functioning, but the monitor won't work. Any ideas? Thanks in advance

Hey everyone, I'm in dire need of some help with my PC. The computer turns on fine, and boots up (can hear the windows start up tune) but I can't see anything on the monitor. Here's the details:

I was playing a computer game on friday, and during that it crashed. I have no idea if this is when things started or not, but I restarted and it was fine.

On sunday I had another crash, only the screen flickered once or twice and there were green pixel lines going from top to bottom of the monitor , about 2 inches apart in a perfect pattern. When I restarted, there were no graphics on the monitor. The light was flashing indicating it was on power saving mode.

I took the computer apart, unplugged everything, and put it all back together, and for whatever reason it worked fine for about 6 hours.

The next day I turned the computer on, and it loaded fine, but shortly after there was the return of the green pixel lines, with the added addition of the top left corner of the screen being filled with green pixelated triangles in a perfect pattern. These were flickering furiosly.

I tried restarting my computer, and again I got no graphics posted to the monitor. However the computer booted up fine, and I heard the start up tune, and 5 minutes later I shut it down by pressing the "Power Off" button on my keyboard.

I tried another monitor and again, got nothing. I then tried taking the computer apart and putting it back together again, only this time it didn'... Read more

A:Graphics card doesn't post any graphics to my monitor, computer boots up fine

Its usually just the graphics cards, they do fail especially if they overheat - then video card fan not speeding up might have been the problem - most are dynamic and should actually speed up under load. Depending on the manufacturer of your 8800GTX you might be able to get it replaced under warranty if they have a 3 year or greater warranty.

Although I bought this computer new in late 2015, I'm pretty sure it is old stock as it came with windows 7.  I wouldn't put it past Walmart to pull such a thing.  I did upgrade to windows 10 and the computer has been operating fine since.  Last night during a storm we had a power outage.  This morning the computer wouldn't start up.  The noises are all normal, the fan comes on, the green light on the psu is on and flickers once during power on and then remains lit.  But there is no image on the monitor.  Monitor seems to work fine.  When powered on it shows going through test to determine signal and then finds none and goes to sleep mode.  I called HP support since I registerd my product and received a confimation email from them saying that is was registered.  But they claim that it is a 2011 model and void of warranty so wouldn't help me.  Even though I have had the unit less than 6 months.  I tried a start up while pressing f11 repeatedly but nothing.  I disconnected all periphials except for the monitor and still nothing. I'm at wits end, any suggestions?

A:Computer won't start monitor doesn't receive signal

Update: I guess I should have done more research before posting question.  I found a thread that said to do a hard restart.  After performing two, the computer fired up and seems to be working properly. Any feedback?

I am not Even Sure if Its Freezing

There is a computer of a friend of mine. We took every single piece out and cleaned the dust on the pieces. After putting everything back together, it doesn't boot up properly. I see the bios screen than it asks me if where to boot, I choose HDD option. Then windows xp asks me what type of start up i want to go with. I chose normal, safe mode, safe mode with command prompt but whatever i chose didn't matter, it didn't started up.

When loading with safe mode option, it always freezes while loading amdagp.xxx file. When loading with normal mode option, i see gray bar at the bottom progressing and when it gets fully gray, there suppose to be a windows logo but instead i get a black screen.

I thought it might be the hard drive damaged and replaced it with another hdd of mine which also has xp professional on it. But it had the same problem. What are the possibilities? What can be wrong? Computer is HP Pavilion XT928.

Thank you

I would greatly appreciate help with my problem. My PC, an Acer Aspire AM5641-U5630A with Windows Vista, only starts up sometimes. When I press the power button, the blue power light comes on and the fans start sounding. However, after it quiets down there is no beeping noises and a display does not come on. On times in which the computer does turn on, a beeping noise is heard and an Acer logo display comes on before it proceeds to start up like normal. Once I'm past the Acer logo the computer works fine. It seems to be random as to when it powers up but I have tried an upwards of 20 restarts before.


A:Computer only boots up sometimes, power light on if it doesn't

This is most likely caused by a weak or failing power supply. Open up the case and make sure that the fans are running and everything is free of heavy dust and other debris...

Well I am frustrated and I really don't understand what is going on.
I bought this computer about 1 month ago, and have had problems with this computer ever since. So the problem that I have had the whole time, is that the monitor will either lose its signal. At first, it was about 30 minutes to an hour before it just lost the signal. Then, I got some new RAM. Nothing changed, in fact it got a little worse. Next, I bought a new power supply. Nothing changed. Then, I bought a new hard drive. Nothing changed. This whole time, I would try consistently every day to get my computer to work. During that whole time, the computer would lose the signal faster and faster. Then, about a week ago, it wouldn't get past the bios screen. Then today, I received a brand new motherboard. Now there is no display, no matter what. Also, I have tried using my computer without my dedicated graphics card, using the onboard graphics. Same result. Also, before you tell me to get a refund, its too late. I bought this off of eBay, so there was only a 7 day return policy. I am absolutely stumped, I really don't know what is wrong with it. The new motherboard doesn't boot at all, the fans just turn on at full power, and there is no display. I also don't believe that the dvd drive can mess up anything.
I really appreciate your help,

Also you can hear the computer booting up. I have a orange light on the power switch on the monitor, also a orange light by the reset button on the case. If anyone can help me with some ideas I'm in total gratitude.

I'm not the most knowledgable person when it comes to computers so please answer as if Explaining to a 10 year old. My computer just completely powered down while I was surfing the web, upon rebooting The screen on my monitor (currently using my tv and connected by HDMI cable) was blank despite the PC appearing to boot up normally. I.E. All fans were running lights displayed on the outside of the machine and even internal fans and systems began to run but there is just no display on my tv. I tried unplugging the system with the power switch set to off and waiting for 10 minutes and rebooting but to no avail. All the websites I check are so unhelpful, I'm a really smart guy with an engineering degree so I'm sure with jus a little bit of guidance and some help from someone who knows what they are doing I can sort this out on my own w/o having to send it back to the company.

All of a sudden my monitor started going into sleep mode once the computer booted up. I went into safe mode (boots fine that way) and uninstalled the video driver. After that the computer would boot normal, but when I try to reinstall the new driver the monitor will do it again part way through the install. In a nutshell, I can only boot the computer into safe mode or with the driver uninstalled. Any ideas what it could be?

My computer seems to be on, but the monitor doesn't come on, nor does any of my devices that are connected to the USB ports. I have to switch the power supply rocker switch off and on and then turn the computer from the front power button to finally get the monitor to turn on. Sometimes this works and sometimes it doesn't and I have to do it a few times before it works. Is this a power supply issue, motherboard issue, or driver issue? I don't mind it that much because the computer still works, but it is getting annoying. Your advice or info is much appreciated.

P.S.---This all happened after I tried to over clock the CPU and the frequency was too much that I had to reset the mother board.

Occasionally I have this problem occur once in a while but I usually fix this problem by unplugging
the power cord to and replugging it back in. I think the problem lies in the graphics slot or the graphics card itself.

A:Computer boots, but monitor is stuck on amber light

Read other 10 answers

This is a problem that has only just started. I looked up my Bios, and I seem to be running AMIINT 10 Version 1.00.
Anyways, to the actual problem. I left my computer on last night so that I could stay in a game server for a friend/event. I went to bed around 5am, and all was fine. However, just a few hours later, my sister woke me up to say that my computer had begun to beep. Indeed, I heart it - repeated beeps that went on without end. They were two beeps that just repeated over and over again; one being a little higher pitched than the other, but each individual beep being fairly short. I immediately shut off the system, and left it off, assuming maybe that the CPU had just gotten too hot. However, since this was the first time I've ever heard this beeping, I was worried.

Later, I opened up the case. Made sure everything was seated properly, which it seemed to be. The heatsink fan seemed fairly dusty, so I cleaned it a bit. Then I started back up. During start up, the beeping continued, just as it had before. Although abruptly halted as soon as I came to me desktop. Since then, everything seems to be working fine, but I'm still worried; as the beeping seems to be an indication of a serious problem coming my way.

So does anyone have any idea or suggestions about what's wrong? If they can figure out what's wrong?

A:Computer Boots, but Explorer Won't Start

Read other 13 answers

I have Windows Vista on my laptop and everytime I reboot my computer it takes forever because as soon as my computer boots up 69 processes are running. I use to play computer games back in the day when I had a desktop and for best performance in my games and fast reboots I would only have like 25 processes running when my computer booted. I remember there being some type of program that I was able to run and then I showed someone on a forum the results(which showed which processes were all running on my computer). They were then able to tell me which processes did not need to run at start up so that I could set them not to run. I know how to use msconfig and change my startup configuration, but I do not know which processes I can tell not to startup on boot because I do not want to mess up anything important like my norton and systematic antivirus software. Any advice/help would be greatly appreciated.

A:Too Many Processes Start When My Computer Boots

Hi, My question to anybody who says they have TOO many processes running is to ask, How do you know what is TOO many? What problems are you having and why do you believe processes are to blame? This program will give you more control, it is a professionals tool so be careful do read the help and not just plow in.

The biggest cause of poor performance is Norton, getting rid of it will do your system a world of good.

A:Computer boots with no task bar/start button

Try this.

When i got home today didn't my computer work, my girlfriend has been the last one using it. So don't know how things were just before the shutdown or anything.

when i turn on the computer i get to the screen where "touch bios" is and where i can see the options like Bios settings, boot menu, xpress recovery.
but i cant press anything, and after about two seconds on that screen the PC shuts down again.

The keyword lights up so there is a responds on it, but just doesn't work to press anything before it shuts down.

My old Windows 7 desktop sounds normal on booting up but I can't see anything on the monitor. I may not have the monitor connected properly.

A couple of years ago I bought a used corporate desktop PC with Windows 7 and used it for a while. Then I bought a new laptop and I haven't used the desktop since. Now I need to get a couple of programs off the desktop. But when I turn it on nothing shows on the monitor. The computer sounds like it's booting up okay.

I am using the very same monitor that I used before when it was working. And yes, it works and I have it turned on. (I am typing on this monitor right now (with the newer computer)). This desktop has a large port for a monitor that you connect a splitter connector to and then connect the monitor to one of the two smaller jacks coming out of the splitter connector. As I recall. when I first bought the computer I connected my monitor to a monitor port on the computer which fit the monitor's cable and it didn't work. I contacted the seller who told me to connect it to one of the splits and it worked.

But for some reason now it's not working. It could be something simple. It may have something to do with the 2-monitor configuration of which I know little.

So my question is how can I proceed toward seeing what's going on on this Windows 7 desktop computer enough to retrieve several Visual Basic programs?

A:Nothing shows on monitor after start computer / 2 monitor Win7 desktop

Project mate soem system specs on that desktop would be handy ie what graphic hook ups does it have on the I/O panel and the monitor too.

One alternative is to take out the hard drive hook it up using a USB to (I assume it is SATA) to SATA drive gadget and view it as an external drive. If it is an IDE one the gadget will still do it. See pic.

First of, my monitor exhibited signs of flickering during start-up, but only minor ones and would just stop at the 'Welcome' screen of windows so I didn't give it much thought. Iv'e been using it with the cpu the same time I bought the monitor.

But after some time, the flickering got worse. It went from 1-2 second interval flickers to a whole 10 seconds of blackness before it showed anything.

Now,Iv'e got a new cpu but still using the old monitor. After a day or so, the monitor exhibited the first symptoms of my first cpu, so I just dismissed it. But after a week, It got a hell worse, before I even start-up my computer, the monitor doesn't show Analog/Digital at the top-left corner of the screen. PLUS my cpu keeps restarting after I pushed the ON button after 10 seconds or so.

My question, Is the monitor responsible for the restart and what could be the reason for the flickering?

Thanks for a fast reply.

Welcome Pokeman5 to the windows 7 forums.

The graphics card might be your culprit. Please update your system configuration settings under user cp so that others can maybe help you.
Usually the monitor won't stop your machine from booting. The graphic card most likely be the cause.

There is also the possibility that your power supply could be defective or going bad. Lots of possibilities.

Hi, I've the following problem: My laptop (Acer Aspire S3, Windows 8.1) doesn't see my external screen anymore (Samsung P2370, connected with HDMI->DVI). It used to be fine, with plugging in and out when needed, copied or shared screens and all. Now, the computer doesn't see that there's an external monitor connected - when I try to switch between them (Function + F5), I only get the laptop's screen as a choice. No plug&play dingaling when I plug the cable in or out.

The external monitor does see a difference, though: when the cable's plugged in, it's black, and when it's out, I get the floating "check signal cable".

Sometimes, very rarely, it does work without any problems. Sometimes, also rather rarely, the laptop shuts down when I plug the thing in (or out? forgot).

I updated the graphics driver through the device manager and there actually was an update, no difference.

All of this might (!) have started around the time of the latest Windows update, but this could be a coincidence only.

Where could the problem be - cable/plug, socket, Windows...? (I'll see if I can try another cable and screen somewhere.)

serveral days my computer just got a problem.
Its monitor won't display anything even though my computer is on.
(LED green light on the monitor is keep blinking, even though the comp is on)
Also, there is no beep sound when it happens.
So I have to turn my computer on and off (also restart (reset button) many times. and sometimes (rarely) When monitor starts to display, it shows that my cpu is overclocked at the wrong speed (1100 instead of 2500). I have to either re-overclock or press restart button in order to get CPU running at the correct speed.
It's like 8 out of 10 times (that) my monitor won't display anything even though my cpu is on.
I also open my computer case, checking fan, heat sink, power supply.
They're working fine. Heat sink and CPU fan is actively running. Power supply is working. Green Light on motherboard is on.
I also unseated and reseated graphic card. It wouldn't work.
I tried reseating RAM. It did work for a while then the problem came back.
I haven't updated or changed any setting on my computer before this happened.

Here is a specification of my computer
PSU 300watt
Motherboard: ASUS A7N8X
CPU: AMD Athlon 2500+
Ram: 2 GB DDR
OS: WIndows XP SP2
Graphic Card: nVidia GeForce FX 5200 128 MB

Any one know how to solve this problem or having a similar problem?
Thank you

A:My Computer Turns On But The Monitor Doesn't ?

This sounds like a computer problem and not a monitor problem. Try another monitor first, to rule that out

Well I've come across a problem. For some reason, when I go to Start > Sleep, my monitor enters a stand-by sleep mode, but my computer won't. Since the monitor has its power off and I can't see anything, and the computer is still on, I have to manually shut down by holding the power button down. It doesn't sound like the computer is really doing any work, but it just won't go into sleep, and I don't know why. It was fine last week.

Thanks for any help

Also: When I boot up the next morning (having manually powered down the night before) I have to boot in safe mode before I can restart and boot normally. If I boot normally, it stays a little bit longer than normal at Please Wait... before it gives me a password field, and then it won't go past the next screen (I forget what it says...windows is loading maybe).

A:Monitor sleeps, computer doesn't -> Help :O

I have this same problem: put the computer to sleep and the monitor loses video signal, but the case fans, hard drives, power LED on the case all stay powered up. It's like the OS goes to sleep but the power to the computer stays on.

I asked about this problem on the TechNet forums, and someone said it could be a problem with Gigabyte motherboards. The good news is that I installed build 7229 and my computer slept fine. So this problem should be fixed with the final version of Windows 7. (I had problems with Explorer crashes in 7229 so I went back to 7100.)

It all started when I put my faulty power supply from my other pc on this one. THe computer gradually started shutting down, then at startup when it said COMPAQ, all the pixels where weird and displaced in random locations and the monitor would display black (but ON nonetheless), so me and my dad assumed it was the PSU.
Bought a new power supply, still same problem. Thought it was the video car (8600gts nvidia), bought a new GPU (ati 5550 1gb ddr3). Now the computer doesn't display anything on the monitor, the monitor acts as if there's no information being sent to it so it goes to standby mode. Replaced DVI cables, same problem, swapped monitors same problem.

I have no idea what it is at this point. Would someone please help me out?

Thank you.

PS: the computer also does not make that beeping sound at start up anymore, if that helps.

Hello, I have a Acer Aspire TC-710, with 8 GB RAM, and an Intel i5 processor.  I have a 2008, Acer, LCD monitor. It does not have HDMI, so I have to use an adapter. The model number is, ETLAN0802481807F924200. It seems the monitor will restart randomly. I very, very highly doubt this is the computer's fault (though, I cannot confirm), as it is a few days old, and, when restarting, the monitor has a different font/layout then my computer would use while powering on. If I am playing music and it restarts (or whatever it does) I can still hear the music. Any way I can fix this?

I'm building myself a custom computer, everything is put together, but now it seems something is wrong with the video. The monitor works, it just doesn't respond to the computer. It's an LCD monitor and I'm using a Radeon Sapphire X800 256mb (AGP). Not sure what to do, everything is BRAND new

A:Monitor doesn't respond to computer?

Put a CRT monitor on it and check the Display/Resolution. LCD monitors only work on certain resolutions, so you'll need to find out what your works on and set your card to that.

You haven't by chance upgraded the graphics card recently have you?

Hi, i recently upgraded from Windows XP to Windows 7 Ultimate. I have experienced a number of problems, and have muddled my way through most of them, except for this one. Sometimes, and this is completely at random, when i turn on the computer, i get no picture, but i can hear sounds coming out of my speakers. However, if i boot into safe mode, it comes on every time. It is notorious for doing this when i install updates, and I have not been successful at installing updates yet. I am ready to go back to XP, but may consider staying if i get all the bugs worked out. Here's what i've done so far:
1. Updated Graphics Card Drivers.
2. Under Power Options, Set turn off monitor to never.
3. Changed S3 to S1 in Bios (this corrected the sleep issue i was having, apparently common)
4. Booted into Safe Mode, Under Device Manager, Changed settings for USB Root Hubs to allow them to stay on.
Have tried all of this, and still nothing. I know for sure the graphics card is fine, and i am using the most up to date drivers for my card. Here are the specs for my system, maybe this will help:
Dell Dimension 5100C
3.0Ghz Intel Pentium 4 processor
2.0 GB of Ram
80gb hdd
ATI Radeon X600 Series graphics card; 128mb
Windows 7 is the 32 bit version. Thanks for any and all help.

A:Monitor doesn't come on after turning computer on, sometimes.

2 Things come to mind... 1 is that you wouldnt have to quote your system specs in a post if you filled them in on your profile. AND...

Your video card is at the very bottom of the compatibility for Win7, 128MB video memory is a very low amount for today's PC's. Make sure you have all Win7 advanced video tweaks (Aero, etc.) turned off.

Hey TSF,

I was performing a system restore earlier when, while the process was occurring, I accidentally knocked the power out to my computer. Now when I turn on my computer it goes to the boot screen where I can choose a normal start up or a safe mode start up. Neither work as when I start it up, it just seems to get stuck at the green loading bar screen.

I also have the option to boot from my recovery disc. But after the "Loading Windows files" screen it goes to a black screen and nothing happens. I'm freaking out because I do a lot of work at my computer and can't get it to work (on my brother's computer at the moment). I also don't want to lose any important files on the computer. What can I do?

I have Vista Home Premium on SP2


A:Accidentally shut down computer during System Restore.. computer doesn't start up

Do you get any options with the Recovery Disc? If you do look for an option called Startup Repair and try that. It should replace the mbr and other essential boot files for you.

I recently decided to connect my computer to my TV. After looking up various cables, I decided I would go with an RCA cable, a 75 foot RCA cable.. Before drilling holes in my wall, I decided to test the wire, and I'm glad I did..

I get nothing but a pure black screen. Normally when I connect a device to my TV (Pioneer Monitor) and the device is off I get a deep red glow, right now I'm getting nothing... I've tested with three TVs and I get the same effect every time. I do not have another M/M RCA cable to test out anything.

Going onto my computer, I see in the Display Properties that my computer lists four monitors (always has, even though I have always had one connected up until now). It refuses to let me enable three of them.. If I do, it just disables them automatically.. The device manager sees something is connected, but it just says, "Generic Non-PNP Monitor." Been playing around with it for about three hours, after looking on other things, decided to try here.
