windows will not open after changing 8 to 10

Hi, I have narrowed down a list of possible causes for your problem and hope this can be of some use

1. do not have enough ram in your system this can be fixed by replacing the ram modules with 2 sticks of 1 GB RAM most of these laptops come preloaded with only 512 MB of RAM.
2. you tried installing a 64 bit version of windows when the processor in these laptops are only 32 bit.
3. the single core processor is not powerful enough to run windows 10
4. your boot drive or HDD does not have enough capacity for windows 10 (unlikely, as it would have canceled the install if there was not enough space
5. if you aren’t confident in handling computer hardware then your best option is likely to either revert to windows 8 if possible using a fresh install or install a free distributive, I would recommend a 32 bit version of Lubuntu due to it’s user friendly UI and it’s low system requirements you can download the ISO by clicking this link http://cdimage.ubuntu.com/lubuntu/releas...
6. if you are inexperienced with installing operating systems then I recommend searching YouTube for a how to guide on installing Linux or other operating systems, Alternatively you can also flash windows 8 to a usb drive here https://www.microsoft.com/en-us/software... make sure you have the flash drive you intend to install on inserted in your PC prior to running your installation software in both cases and make sure the flash drive is at least 4 GB in capacity (8 gb strongly recommended) and if after inserting the flashed drive into your computer and start it and it doesn’t boot, then you may have to change the boot drive order, this process shouldn’t be too hard if you look up a quick how to on YouTube. I know this is a lot of information to take in but if you push through it this should solve your problem, I hope this was able to help, and good luck
