Sometimes it happens that you turn on your computer, but for some reason it does not boot. Although the last time everything seemed to work. Why Windows does not load? There are a lot of reasons.
First, to look for a problem, you need to look at how the system does not boot. Up to what point is the download going.
Consider the “blue screen of death”. If the computer starts to load, and then displays a blue screen, then this most likely means that you have problems on a physical level. That is, the problem is in the gland. But it also happens that the operating system crashed , or some files that cannot be read from the hard drive are damaged.
Read the message that will appear on the screen. If it is said that it is impossible to read any file, then there are problems with the hard drive. If the message describes some other error, then most likely it says hardware conflict.
So, you do not load windows, and a blue screen appears. We do the following. Disconnect all connectors, devices and more. That is, almost everything that is inside the system unit. Blow out the contacts and reconnect them. You can also try connecting the hard drive to another SATA connector. A normal board must have at least 4 connectors.
If XP still doesn’t load, then you can turn off the optical drive or connect it to another connector. Pull out the lines of RAM, blow out the slots and reinsert them. Launch. If it does not boot again, then you need to think about installing a new operating system. We will talk about this a little further.
It also happens that nothing is displayed on the screen.
In this situation, the problem is precisely related to the video card. Either she failed, or just a bad contact. Look at her carefully. If the capacitors do not explode, then pull out. Blow out the slot and then reinsert it. If again no information is displayed on the monitor, then you need to check the monitor and video card.
You can find a neighbor or acquaintance who can help test them. First, connect a foreign monitor to your system unit. If the information went to the screen, it means that your monitor burned out. If there is no data, and windows does not load, then the problem is in the system unit.
After that, we put your video card in the system unit of your friend, who kindly agreed to help you.
Two options are possible. Shows and does not show. If the system started to load , and the information went to the monitor, then your video card is in order. And this means that you have a problem with the motherboard, because the video card is alive. Try inserting and removing the video card several times. If all else fails, then change the motherboard, or try inserting a neighbor’s video card, because maybe your video card and your motherboard have a conflict.
If there is nothing , and windows and BIOS do not load, the video card burned out. Will have to change it.
Black screen after BIOS.
A variant is possible when your system starts to boot, but then a black screen appears and a minus sign flashes in the corner (underscore). Here you should also purge and reconnect the devices in the system unit.
Usually, in this case, windows does not load due to some problems with the software part. If connecting a hard disk and a drive to various SATA connectors does not help, then try reinstalling or restoring your operating system.
You can try to restore the boot.ini file. This can be done using System Restore using the command line.
A common solution is to disable the automatic reboot of the system when an error occurs. To do this, after displaying information from the motherboard, press F8 and select the option to disable automatic reboot. After that, Windows will give you a message about the real problem, not a black screen.
