computer shutdown, doesn't turn on right away when it does turn on its black

Q: computer shutdown, doesn't turn on right away when it does turn on its black

I just put together my first computer 6 months ago. It abruply shutdow in the middle of writing a paper for school. I couldn't turn it back on right away. after trying a few times, it turned on. All the fans are working even the fan on the power supply, the motherboards lights are on. My graphic card in on the motherboard. I think it might be my power supply because when I first put it together I didn't plug in the smaller power connection to the motherboard and the same thing is happening, black screen. It's like my computer isn't giving my monitor any feed. I will have more info when I get home. I can't get in to bios or safe mode.

I have a bit of a strange issue with my computer. Forgive me if I'm a little too descriptive, but I'm not sure which details are relevant and which are not for such a problem. First, the specs:

Model: eMachines T2984
Operating System: Windows XP Service Pack 2
Processor: Intel Celeron D Processor 340, 2.93 GHZ, 256K L2 Cache, 533 MHZ FSB
Power Supply Unit: Bestec Model: ATX-250-12E REV: P7
Motherboard: I can't tell, but it appears to be an Intel motherboard by the number of Intel labels on it
RAM: 512 MB DDR SD originally, added 1 GB a couple of months ago
Let me know if you need anything else...

Yesterday, I got home from shopping around 1PM, and I tried to start the computer. I pushed the power button, and nothing happened. I checked all of the cords, and they were all plugged in. Not knowing what else to do, I opened up the case to see if there was something obviously wrong. The only thing that I noticed (other than a bunch of dust) was that the power supply unit was still hot. I shut the computer down about 5 hours earlier after about 20 minutes of use, so it seemed strange that the power supply was still hot. I unplugged the computer just in case there was some sort of fire hazard.

At this point, I called a friend who suggested that the problem might be with the motherboard or the power supply unit.

A few hours later, I plugged it back in to try to get it to work. As soon as I plugged it in, the entire unit suddenly started "running" by itsel... Read more

I would suspect that the Power Supply Unit (PSU) is going south. If you have a spare one laying around, install it and see if the problem goes away.
You can buy a new,better PSU from Newegg for about $40.00. I have used a Thermaltake 430 watt in one of my machines for some time now and it works well.
You will have to check the size of your PSU to be sure a new one will fit into the eMachine.
Here's the page with that PSU on it. It's the last one on the list.

Been having shutdown issues for the last several weeks following some issues i was having with an SSD drive and after a few hours of some hard soul serching in safe mode boots, i figured out that its an Nvidia driver that stops the machine from powering down after i hit the shutdown on Windows 7, i've tried reinstalling old drivers as well as the latest ones but i still get the same issue, it shuts down and powers off just fine NO PROBLEM!!! when i uninstall the nvidia drivers, but the second i load them back into windows i get the same problem again, if anyone has any thoughts or solutions i would really apreciate it, i've been trying to sort this bloody mess out for 2 weeks or more, and finally got it pined to the nvidia drivers.

I've done bios settings and cleared the bios completely, nothing is overclocked, everything is at factory defualts, i've tried updating the bios , and i've also disabled the SLI mode and nothing effected it, and also done several install of windows. One last thing, it shurts down and turns off perfectly fine in safe mode.

any help pls would be apreciated

If I unset "Allow the computer to turn off this device to save power" on the Power Management tab of my USB Root Hub properties, then when I attempt to restart my computer from the Start Menu, Windows shuts down but the computer itself keeps running,
i.e. the power light stays lit and the fan continues to run. In order to actually shutdown, I have to press the power button for a few seconds. Upon reboot, there is no indication of a failed shutdown from Windows. However, I am able to shutdown from the Start
Menu without problem.
Is this really the intent of not allowing the computer to turn off a device connected to a USB port, i.e. you can shutdown but you can't restart? Seems a bit arbitrary to me.

Hello Folks,

I'm not sure if my issue is with hardware (possibly MB?) or graphics card, so please forgive me if I've posted in the wrong section. The first problem I was having was random blue screens of death that displayed graphic card driver issues. I was able to remedy that by updating my graphic drivers and have not had an issue since.

However, ever since then I have been running into another hardware or graphics-related issue that is random and completely stumping me. What is happening is, I will be on my computer, leave and turn my monitor off, and (randomly) when I come back to use my computer again, when I turn on the monitor there is no signal and a black screen (e.g. when I turn my monitor on my desktop will pop up and the light on my monitor will turn blue, when it doesn't turn on there will be a black screen and the light on the monitor stays yellow as if it is idle). I have tried swapping out the monitor to see if that was the issue and the same problem persists, so it does not appear to be my monitor or VGA cables.

The only way I can temporarily fix this issue is to reboot/restart my computer and viola! The monitor works again and I can see everything. This issue is very random. Sometimes I can go weeks without an incident, other times this is happening a couple times a week. I honestly don't know if it's my motherboard or video card or what. My PC isn't overheating, I'm not overclocking, and all of my drivers are updated.

So I've been having this problem with my computer for a couple of weeks now.
After I choose to shutdown my computer , windows does it as usual and is very quick at it since I have an SSD, however after the shutdown screen disappears and my monitor turns off, the fans are still spinning and the motherboard makes some noises (not beeping) as if it's going to power on or off.
It eventually shuts down after 25 to 30 seconds which is weird in a way since everyone in the internet that had the same issue says that they have to hold the power button in order to turn the pc off since it won't by itself.
From the suggestions that I found in the internet I tried them all, updating my BIOS, leaving my computer unplugged for 2 hours and without the CMOS battery, installed the new Windows Creator Fall update today, updated all the drivers on my computer, ran CCleaner to fix registry errors but nothing fixed it for me.

My computer specs are the following :
CPU - Intel Core i5 7500
GPU - Asus Strix 1060
RAM - 12 GB DDR4
Motherboard - Asus Z170 Pro Gaming
PSU - Aerocool Strike-X 600W
Operating System - Windows 10 Pro 64 Bits

Also since this problem started happening, during the boot after windows has loaded and when it should show the login screen it turns off my monitor for 5 seconds but turns it right back on and it shows me the login screen as usual.

Hello everyone!! (I think I'm the only one here though on a Saturday night )

Anyway, I've been reading through the forum to see if I could find some answers to my problem with my HP and the closest one is "Old School" dated September 1, 2006. So, I've noted some of the answers and I'm going to try some things (that apply) tonight with my computer.

However, the initial problem started when I began to notice my computer slowing down, so I decided to remove some programs, files that I no longer needed. Afterwards, it didn't seem like it help any at all. A few days after that I began to get errors saying the memory was low and so I decided to completely start all over, going back to when I bought the computer new. However, when I attempted to do this it wouldn't let me saying the memory was low or not enough memory. Next thing I knew my computer completely crashed and I haven't been able to get it back on. Here are some of the things that are coming up when I try to start it.

Hello --
I've got a Dell Inspiron 6000 laptop, it's about 4-5 years old. I'm not very tech savvy.

A weird thing started happening recently:

Whenever the computer shuts down (Standby, hibernate, or full shut down), either b/c I power it down or just b/c I close the lid, the computer refuses to turn on again.

When I press the power button, the fan starts up, the power light comes on, the caps lock light blinks 9 times and then it turns off again. Happens regardless whether the laptop is plugged in or on battery.

I have discovered that I can get the computer to start up by holding down the "play/pause" button bellow the touchpad and pressing a bunch of keys on the keyboard simultaneously. This causes the computer to turn on and opens a program called Dell Media Experience (which I've only used occassionally before). But this "solution" is not reliable and seems to be getting less and less effective(the first time, I just pressed the button, since then I've had no success unless I also hammer the keyboard a bit).

At this point, I'm afraid to let my laptop sleep or turn off for fear that it will never turn back on.

Anyone have any idea what the problem is? PSU? Motherboard? Something easy to fix that a non-techie like myself is just unaware of?

Plz let me know ASAP.

Ok here is the problem we been having. It seems that we have problems with our breakers going on and off constanlty but this time it really affected our pc. Our stupid landlord didn't pay the electric bill so our power was shut off durring the night. once it was back on we tried starting our computer back on an guess what nothing happened.

So i checked things out. first i checked the reset switch and we bought a new one of those, new power cord for the power supply, nope that wasn't it.

There are two color light bulbs by the reset switch the green one comes on when the computer is working. its not turning on and the yellow remains on tho so i figured its still getting power but maybe not from the power supply but from the battery since its a pretty big battery. But the fan isn't running, neither are the drives and other things so i think it is in the power supply. Do you think it might be the mobo tho? This computer is only two years old and it has a celleron proccessor and so i was also wondering could it be the processor too?

So here is the questions, what do i replace first? The power supply , proccessor, ram, mobo or just buy a new comp?

Just to let you know yes its plugged in and its turned on and the monitor is turned on also.
 

A:Computer doesn't turn on

First thing you should buy is a battery backup. Computers are very senstive to electrical problems, using a battery backup and a good quality powersupply will save you possibly thousands of dollars.

Most of these issues I've run into have a sort of chain reaction effect on the destruction of the PC. In all likelyhood, your powersupply is fried. If it was a good quality powersupply then that should be the extent of the damage, however if it didn't fail correctly then your motherboard could also be damaged. Depending on the quality of your motherboard, any various components of you PC could also then be damaged.

So giving that I understand your situation correctly, I'd first buy a battery backup (I prefer APC but Belkins are decent), then I'd buy a Powersupply (not a cheapo 350w Powmax, look for a good name like Enermax, Antec, Fortron, OCZ, or Seasonic) then see if your PC will start up. If its a no go then you need to replace the motherboard (at which point a system upgrade becomes an entertaining idea).

If at all possible try testing the components of your PC in another working computer so that you can devise what's good and what isn't.

But regardless, get a Battery backup.

Okay, so my desktop computer used to be on all the time and then all of a sudden it went off and it just simply is NOT turning on. Pressing the button to turn it on does absolutely nothing. I've tried leaving it unplugged for a week, and it still didn't work. There is a light on the motherboard so I know that the motherboard does have power but I can't figure out what's wrong. Can someone please help me turn this pc on?
 

A:Computer doesn't turn on

The problem sounds like the power supply, if not that, then the motherboard. A good way to narrow the problem down, would be to swap a known working power supply, and see if the computer boots up. If it doesn't, there is a problem with the motherboard (considering all wires and cord are connected properly and there are no other power issues such as AC outlet, surge protector, bad PSU power cable etc.)

I need serious help. I got to school online and am in a really hard class. Now, my computer is flaking out on me. I like to turn my computer off when I am not using it because periodically the computer sounds loud like I am doing twenty things at once when I am not even using it. Then my computer gets quiet again. I have XP Home Edition and it doesn't turn all the way on sometimes. In these instances, all the lights that are supposed to be lit on the tower are, but the monitor doesn't turn on. I have to hold the power button in until the tower turns off, I wait about thirty seconds then turn on the power again. It is like Russian Roulette, sometimes it works, sometimes I have to do this again. It has gotten slower too, my computer is so freakin slow, and it just froze on me for a moment. I am not sure this next piece of information will have anything to do with this but last week I had ran and downloaded the MS Essentials program for viruses and spywares. It said I had Win32/Induc.A, and it said it was a virus. All the files listed below it I deleted even from recycle bin so I thought it was gone. I looked up information about the Induc.A and it said it attaches to Delphi files if you have them and copy files and rename them as well, which I did a search and found no delphi files. Then the MS Support Page said that if none, it will just bounce around your system in a richochet style.I will check in later, to see if I been hooked. Thank you.

If your computer does not turn off the power when doing a shutdown,
you may need to edit the registry.

Go to HKEY_CURRENT_USER\Control Panel\Desktop
Edit the key PowerOffActive and give it a value of 1
You can do the same in HKEY_USERS\.DEFAULT\Control Panel\Desktop

I have a Dell Dimension 8400 with Windows XP Pro on it. It's only a year and a few months old.

Anyway, a few months ago, I turned on the computer and instead of loading properly, it beeped and nothing showed up on my computer screen. And all I could hear after the beeping was the fan, which I noticed to be abnormal since the machine makes its usual running sounds. So, I opened up the computer and saw that one of the metal strips that covers an unused drive space was loose, so I tightened it back into place, closed up the computer and when I turned it on, all was well.

Now, just a few days ago, the same thing happened except nothing I did could make my computer turn back on. I tightened the metal strips, drives, checked all plugs, etc only to find out that whenever I pressed the power button the green light goes on, the beeping happens, but the computer will not turn on and function. All I still hear is the fan on inside the computer.
Please help.
 

A:my computer beeps and doesn't turn on, help!

Does the beeping stop after a certain number of beeps each time? If so, count the beeps and refer to the online help available through the PC manufacturer. It's possible the movement when you opened it up caused the machine to work again and was not related to the metal strip. (possible). If you have more than one ram module, try each one separately. This may single out a bad one. If there is any way that you can borrow a friend's ram memory module(s) try different ram. Almost every time I've had the beeping problem, it has been ram related.

Hi,

I have been searching everywhere for an answer to my problem and have yet to find something. What happens is, after using my computer for extended periods of time (6hrs+) if I for some reason, shut down the computer (Or say the power cord gets yanked out) it will simply not turn back on immediately.
I click the power button to turn it back on, and for a split second the fans, etc, spin and then just cut out and everything is dead. If I click the power button on a second time, nothing even starts to work for that split second; its just completely dead. Now, if I take the power cord out, wait 10 secs, and then put it back in and power it on, I get the same split second power up, and then it goes dead.
The only way I get it back on again, is to leave the power cord out, wait around 10-15 mins, reconnect the power cord, and it works perfectly.
This problem only seems to occur when the computer is "hot", like I said after being on for a fair while, and immediately turning it back on. If I go to use it in the morning after being off all night, I never get this.

The reasons I think it may be, is either a faulty power supply, faulty power switch, or maybe the motherboard? I don't really know (Although I don't think it is the motherboard as it was only replaced a while back because of a burn out :\).
I was reading somewhere about how dodgy soldering can produce different results if the computer is hot or cold because of expanding/contracting. Could this be a ... Read more

My computer attempts to turn on, then like .3 seconds after I press the power button, it turns off. I opened the case to see what was the problem. The power supply does work, because it is showing lights before cutting itself off it seems.

So far I have a list of good parts, and they are as follows:
RAM
Graphics Card
Power Supply
CD/DVD Drive
Hard Drive
Heatsink/fan

I have bought a new motherboard and CPU recently.

They are: AMD FX-4100 Quad-core and ASRock 970 Extreme 3.

Any suggestions as to what is wrong?

Thanks!

A:Computer Attempts to Turn On then Doesn't

A couple of things to start with:

You say "I have a list of good parts".

What makes you think they are good?

Do your fans start to move when you try to start?

Can you hear the hard drives try to spin when you try to start?

Hello,

I've just returned from a weeks holiday and I tried to turn my computer on but it fails to do so.

I left my computer as I normally do. I use it everyday usually, but returned to find it not working. The red light on the front of my case is on, indicating that there is power to the machine.

I opened my case and pressed the power button to see if anything happened. I noticed that my fan moved for half a second when I pressed the power button, but that is it.

I have unplugged the 24 pin and 4 pin cables that were plugged into my motherboard and plugged them back in.

Ive taken out the battery on the motherboard to restart the CMOS (I think it's called that) and put it back in. Doesn't work.

I have tested the computer's power cable with my monitor and that turns it on. I've tested the wall socket with a lamp, and the lamp works.

Any help please?!

Here's my spec.

Gigabyte B75-MD3H
Intel Core i7 (3770) 3.5GHz X 4 (14GHz) L2 Cache 8MB
8 x USBS Ports Onboard Raid 0/ Raid 1/ Raid 0+1

Hello friends,

My old computer (Intel Impression 440BX) was running Win98, I formatted and installed XP Professional. Now when I select shutdown, the computer no longer turns itself off - as it used to. I now get the "It is now safe to turn off your computer" screen and have to manually turn off the power to the Motherboard.

I didn't make any changes to BIOS (AWARD) and I looked around to see if XP changed something, but didn't notice anything. I am not that experienced with all the different BIOS settings.

Thanks for your help.

Can somone please help I have a huge problem.

Firstly when I put my computer on everything was working fine but nothing came up on my screen it just said no signal, I checked all the wires and everything was fine, so was my pc it seemed to work fine it was just the screen that wasn't then i looked at the back of the PC and i saw this red switch which was on 230 then i changed it to 115 and I heard a sound so I changed it back to 230 and now my computer dosent even turn on SOMEBODY HELP PLEASE!!!! also does this mean all my files are safe or are they all gone

A:SOMEBODY HELP!! I flicked this red switch now my computer doesn't turn on!!!!!

Where are you located, Europe or USA?

The 230 is usually non-USA. If you powered your system at 115 and you had a 230 input power, you likely blew your PSU (at best) You'll need to get a new one.

NEVER change this PSU switch if it worked before.

If you ARE USA, and you buy a new PSU, the setting should already be set to 115.

If you are non-USA, a new PSU should already be set to whatever your country uses.

Good luck.

Recently my graphics card stuffed up, whenever I restarted my computer there would be three consecutive 'beeps' and the screen would stay black. I had it repaired and the person handing me back my hard drive (not the guy who repaired it) said that a new card was installed and it was apparently better for gaming.
I played games such as Age of Empires III and Civilization 4, however the games crashed occasionally. Age of Empires had never crashed when my old graphics card was installed (Nvidia Geforce graphics card) however my new card is an Asus, and during the play of civilization 4 the terrain details would disappear and black squares would emerge, then the whole screen goes into negative colours, bright yellows, purples and greens and then the computer shuts off restarts several times. This happened several times before and I would just restart. However it happened and my computer never started again. I cleaned out the iside of the hard drive and removed the dust.
The computer is 4 years old but it was well maintained, the power supply had been changed 2-3 years earlier, its brand is Hi-Tech.
I was wondering wether it is a graphics card issue, power supply issue or motherboard issue. Also I was wandering if replacing parts or buying a new hard drive is the best thing to do.

i was working in Maya..actually just browsing.i havent even created anything.the scene was empty.and i just started to make a basic model the computer suddenly turned off.then in 2 seconds turned on again (almost) but the monitor wasnt showing anything.hdd light was off (everytime my computer starts normally it's ON)..cpu fan was rotating slowly.and the diagnostic lights (i guess) were on on the motherboard..i was afraid that cpu may get overheated (because the fan was rotating very slowly) i cut off the electricity.then started the comp again..this time..the fan didin't even start rotating (just showed little signs that it kind of wants to start rotating)..2 seconds that last..then it turned off again..after that it's on for a second then off for another..it just turns on and off if i dont cut the electricity
and the thing that.if i wait some time.then turn on the comp it goes a little long and wants to start ( maybe for 4-5 seconds) and then the same thing..so i thought it might a overheating problem (though i haven't done anything that could cause that) and disconnected the graphics card, the drives and the hdds..didn't help

havent' had these kind of problems before.the comp is in good conditions.bought in 2009

the specs are:

Quad Core 2.66
4GB RAM
GTX 560Ti
Windows 7
580w power supply

and there's a ups..600v/s i think..it's old..dunno if this can cause the problem.just additioanl info

this is urgent..please help with anything u can.thank u very much

A:Computer turned off suddenly, now doesn't turn on

I hate to guess, but my initial reaction is Power Supply. But the UPS could be a complicating factor.

First, I would remove the UPS from the system and test.

Then, try another power supply in your system or try your power supply in another system. Do you have access to another PS you could test with?

Another thing you can try is to disconnect all external devices, all drives, and any other power draws that you can and see if the system will boot with just basic components: PS, MB/CPU, RAM, Graphics.

If we can eliminate the power supply as the cause (prove that it is good) then we can move on to the other potential causes.

Problem 1:
Forgive my wording if it sounds confusing. On one day I can use my desktop all day with no problems. However, the next day I can't turn on my computer. I can hear fan noises inside my computer and the power button lights up, but the monitor says that there is no signal and promptly turns black. One thing that may be important is that when I attempt to turn on my computer, when the fan is louder then my computer turns on with no problems. On the other hand when the fan is quieter, the computer does not turn on (the monitor receives no signal). The day after, I then turn on my computer and it works completely fine. So currently I tend to use my computer every other day and my computer turns on every other day with no problems (which has been inconvenient).

Problem 2:
For a few months, I have been playing Overwatch (a video game) on fullscreen (19201080) with no problems. However, recently my computer crashes when I play and I cannot turn on my PC right afterwards. On the other hand, if I play Overwatch in windowed mode in 1366768 resolution there are no computer crashes.

Conclusion:
I am not sure which hardware part is the problem and I am wondering what actions I should take to fix my computer. Thanks in advance!

Hello... let me state the problem.

Problem: Computer shuts down randomly. I press the power switch, but it does not turn the computer on. I have to wait a while and press power switch, and it turns on, or I switch the voltage switch (red switch) on the back of the PSU a few times, press power, switch voltage switch back to 110V and then power switch and it turns on normally. (Probably not good for it) It then runs for like 1 hour --> 1 day and turns off randomly again, where i must repeat.


Reason?: I use to never leave my computer on for longer than a day. I never downloaded anything large for it to be left on overnight. During chirstmas I got a Dual Layer DVD-Burner and installed that. I have been leaving my computer on for weeks at a time downloading large files now. Everything was fine for about 3 weeks. Near the end of Janurary it first happened. I didn't think much about it, just turned it back on and it worked fine. About 2 weeks after that it occured again: Now it happens pretty much every day with the added bonus of the power switch not responding for about 1 --> 5 mins.


Possible Problem: The thing I find most insteresting is the fact that after it shut's down, it will not start up for about 1 mins (power switch doesn't respond for a little bit). I can not tell if it is because:
1) I started leaving my computer on for weeks at a time and now Mobo is burning out or PSU?
2) Because I installed the Dual Layer DVD-Burner, and ... Read more

A:Computer doesn't turn on for a few seconds? PSU Problem?

Sounds like it could be the PSU. I had similar problems in getting the bugger to start up and swapping out the PSU seemed to fix it. I've also had problems with the powerup button getting stuck and causing similar symptoms, but with it shutting down my guess would be PSU. Good luck!

Hello.

I have a strange problem and i'm not even completely sure it's hardware related.

I formatted my PC's hard drive and installed XP. I didn't have any troubles with that and it wasn't unusual in any way. Unfortunatelly after that my PC has problems turning on. It restarted a few times during system instalation, updating and installing other programs (which is normal), but after I turned it off for the night, the START button doesn't seem to work properly. For the first and second time I've managed to turn it on eventually (I've unplugged the power cord and plugged it again, I played with the ON/OFF switch, I waited). But the problem didn't vanish. Now it doesn't respond at all. Maybe it will turn on after a while (like two last times), but I'd prefer the problem to disappear completely.

I found this article - http://www.hardwaresecrets.com/article/547 - but I really would like to avoid opening the guts of my PC. Is it possible that the problem is software related? It appeared only AFTER the format and has never existed before.

So a few weeks ago we had to have some viruses removed from our computer, and it seemed like it was working again. Today, when we went to turn it on, the screen would only turn on for about 30 seconds, and then it would go blank. You could still hear the computer running though. Then when we shut it down and tried to start it in safe mode, we weren't able to. It said something like "No support", but when we tried starting it how we usually do, it worked. Now it's working really slow, and the screen keeps on freezing.

A:Computer runs but the screen doesn't turn on

Hi -

Is it a laptop or desktop?

If laptop, try connecting an external monitor. A laptop here loses monitor a few seconds after boot due to a known hardware issue.

If desktop, try another cable +/or monitor.

hey,
When i went to bed my computer was working fine. but when i woke up (8 hours later or so), When i press the power button nothing happens, not even a choke to try and start up. The weid thing is that when i turn on the rear power switch, the motherboard green LED is on. So im not sure if this is consistent with PSU failure? I would have that PSU failure for sure but now im not certain.
i have tried:
Using a known good power socket.
switching the power and reset buttons on the motherboard to see if it was the siwtch
Short circuiting the on switch on the motherboard.
When i unplug the motherboard power cable from PSU, the green LED turns off, when i plug it back in it turns back on.

Does anyone know if its a PSU problem or somethign easier? Because it's really throwing me off. I think i have to be getting power, since the mobo LED is on.
Thanks
Andrew
 

A:Computer doesn't turn on, but mobo LED light on

Hello and welcome to techspot.

I'm not good at all when it comes to this case, but coincidentally, i have the same issue last year.So i decided to write some possible reasons :
1. PSU failure (+12V A rail is too low)
2. Capacitors leaked
3. Heatsink and thermal gel not installed properly
4. Few drives problem such as HDD or optical drive
5. short circuited cables inside the case.

So far, when this problem happens to me, i could not turn on the PC whenever the HDD is attached. But when i unattach it, the computer would on.
Or another issue, i have a fan in the case which i have not installed yet. Accidentally, when i move it with a pincer to the correct position, the metal parts of the fan get in contact with the CPU case. Straight after that my computer turned off, BUT the CPU LED is on.

Well, let's find out more about your computer, can you give your system specs here?

My computer that i own isn't working properly. Firstly, its about 4-5 years old the power button gets stuck. I've been fiddling with it from the outside to come out all the way since if it goes in all the way and doesnt come out, it keeps restarting. When i wiggle it out, it starts and goes.

Now onto my problem now. When i start up my computer, a screen pops up allowing me to press F1 for setup. if i don't click F1, my computer goes to a black screen with a _ blinking in the top right. I can't do anything from that point and when i press keys too many times, it starts beeping after i hit any key again.

Anyways if you guys could help me, I would be very thankful!
 

A:Turn on my computer, black screen

sounds like it may be time for an upgrade

have you made any hardware changes or installed new device drivers?

from what you describe it seems like the system is having some issues booting the operating system from the hard drive, or there could be another hardware fault causing the hangup... like the memory or motherboard itself. if you are able to view the POST screen upon startup (which displays all of the system information and keys to access BIOS etc...) then you may be able to boot from a CD-ROM to run repairs or possibly boot into safe mode by repeatedly striking the F8 key after the POST screen appears.

I turn on my computer, it begans to start up, and then the moniter just goes black and won't show the desktop or anything. It has done this every day for the past week or more and it's getting harder and harder to get onto the computer. What I do is turn the moniter on/off until it shows me a glimpse of the desktop, and then I mess with the screen saver power options (while it continues to keep going black and I have to turn the moniter on and off to get glimpes of what i'm doing), and eventually it just stops going black and works for the whole rest of the day until the next morning.
