How do you possibly fix a PC that will turn on but will not beep and will not display anything on the screen?
Don’t worry, it may seem scary at first but I’ve faced this issue before and was able to fix it successfully, if you’re lucky enough, you’d get a beep code, it means something but if you don’t get any beep or don’t see anything on the screen then don’t worry I’ll walk you through step by step until this problem is resolved.
There are a lot of reasons why your computer is not showing anything on the screen, in this article we’ll talk about them in detail.
First thing first
You will have to make sure first that your monitor and both data and power cables are working properly, the way to do that is to connect your monitor to another computer or a laptop, it’s a quick way to see if they are working fine.
Once you’re done with that you can move on to the next step.
Caution 1: If you just bought this computer and it’s still under warranty then I highly recommend you to take it back to where you got it from, trying to fix it yourself might void its warranty.
Caution 2: unplug or disconnect any hard drives attached to the motherboard or power supply, this is a very important step because during this process your computer will experience a lot of shutdowns until the problem is resolved, so make sure to do that first.
Unplug or disconnect any peripherals including the mouse and keyboard, that way we know these peripherals won’t be the problem if the problem persists.
This is the first component you would suspect, most of the time the RAM could be the reason behind such problems, if you have one RAM only then try another one, if you have two or more try to switch places or just test one by one, if you have tried everything and you still get nothing then move on to the next step.
Obviously, make sure all RAMs are in good shape and clean.
The CMOS battery is a tiny coin-shaped component that stores your BIOS data like settings and date and time, sometimes clearing the CMOS battery by removing it and putting it back after 5 minutes can fix such issues.
Don’t worry, removing the CMOS battery won’t ruin everything, I mean your computer isn’t already working so you’re basically not risking anything except the stored settings and date and time which I think aren’t that important in that case, you can change the settings easily after you fix this issue.
If your computer is too old there’s a good chance the CMOS battery is dead and needs to be replaced, don’t worry it’s very cheap, so replacing it won’t be an issue.
I know what you’re thinking, no way man I’m not gonna mess with my CPU.
Don’t worry, you have all the right to be scared, the CPU is the most important component of your computer and probably the most expensive one.
Actually, replacing the thermal paste of your computer might be a good thing to do every year or so, there are plenty of videos out there that show you how to do it.
Unfortunately, you’ll have to find a new or used CPU from a friend or a repair shop to check if your CPU is causing this problem or not.
When your computer boots and doesn’t show anything on the screen makes you think about the GPU as well, especially if it’s too old or not installed properly, or maybe it has broken components or bad cables, try removing the GPU and try to start your computer without it by connecting the monitor cable to the other graphics port which is basically the motherboard’s graphics port.
If it worked then yaaaay, you could then buy another GPU if you’re 100% sure it’s gone bad.
If the problem still exists then you should move on to the next step.
Another reason for these kinds of problems is the power supply, the only way to find out if it’s causing this issue or not is to try another one, but actually, there’s another way to check your power supply but you have to get a device called Power Supply Tester, this device indicates which parts of the power supply are broken or malfunctioning, if it indicates that everything is working fine then you should move on to the next step.
I know we’re testing everything, but this is how it works, don’t worry building a computer yourself isn’t difficult at all, you should follow a tutorial on YouTube all the way to the end and then try to do it yourself, I was talking about removing all cables and trying to put them back, there are a lot of cables so try not to get confused.
A quick tip that I usually do before unplugging anything is to take a picture of the motherboard and cables before I do anything, then if I ever get confused I look at the picture and see what goes where.
Try to install everything properly all the way to the end, don’t worry about pressing hard sometimes to plug a cable into its port, sometimes you’ll have to do that.
Hopefully, after following this guide your problem was resolved.
