I tried that the forum rejected the file because it was too big in size.

Something similar happened to me a while back. I think I simply set my virtual memory settings to something I manage like around 8 gigabytes.

Thanks I'll try that, I've got my virtual memory disabled because I have a 64-bit OS and 32 Gigs of RAM, so I figured I wouldn't' need it but it can't hurt to set something up on my SSD.

Just did as @Gnargenox said, and as I was doing it I discovered I already had the Virtual Memory Paging file managed by windows, set to 4Gb. I'm going to try disabling the Virtual memory and try it before I put an 8GB paging file on my SSD.

Then maybe you can try it with Pastebin. But I do not know if they have a size limit.

Now I kind of wonder how it turned out for him.

I tried turning off my paging file and it didn't work.  I now realize that because space engine is 32 bit it still would be forced to use only 4 GB, so I did as you said and it works! thanks!

Singh1106, there should be an updated driver for your card on the AMD website, you could try and update.
Edit:
By the look of it, AMD apparently does not provide drivers for mobile graphic cards such as yours, they suggest instead to check for updates in the laptop manufacturer website.

In your se.log I find the following section:

INITIALIZING LOADER
[MT] Number of CPUs: 8
[MT] Worker threads: 7
[MT] RAM granularty: 4 kb
[MT] Total      RAM: 4095 Mb
[MT] Available  RAM: 3815 Mb
[MT] Physical  VRAM: ERROR
[MT] Available VRAM: UNSUPPORTED
[MT] Max. used VRAM: 1536 Mb

Apparently SpaceEngine does not recognize the size of your VRAM.
This could be a driver problem or a problem (bug) in your graphics card!

Space Engine won't start

So this isn't a very pressing issue, but I recently upgraded from a GTX 1050 Ti to an RX 580 with a Ryzen 5 2600, and there isn't a performance increase at all. I have no idea where to start but if I could have some suggestions that'd be great. And I would also like to state that on every other game, I get 60 FPS steady on Ultra settings... so I think it might be SpaceEngine. I've attached my se.log to maybe see if there is anything wrong with the logs, and from what I can see there isn't anything, hence why I'm attaching it. 

TToth, please use https://pastebin.com/ to post your entire  se.log file, and give us here the address of the file. if all you got is what you just posted, it seems that SE can't use OpenGL with your card.

I'm afraid what he has posted are his entire log files! It's probably all SE wrote before it crashes!
I've seen such log files before, but I can not remember where, so I can not help right now.

Have you run it again the 2nd time since swapping out the card? Also it's a good idea to delete the cache folder.

I found every time I change GPU driver it has to build new shader cache and it performs much slower and doesn't attempt to use the available vram the first time so it needs to be run a 2nd time for it to come good or I can delete the cache first before updating the driver (would be the same as installing a new CPU) and should prevent issues.

Also another thing is you could be CPU limited in some places.   You should see gains the most above a planet surface and atmosphere that have some clouds. These areas I found the most GPU bound and CPU not so bound.  Loading terrain is generally always CPU and engine limited so it won't improve with a GPU much if anything at all.  You will see the gains in areas mentioned and only once loading has stopped which is where the GPU takes over the majority of the work.
