Could be the cpu or gpu, and if its older hardware, or integrated gpu you might as well buy a new computer instead of replacing old parts.

Just about a week ago my computer stopped booting, I figured it was just acting up... but after a couple of days of messing around with it I'm convinced it's the hardware or something that is way out of my range of fixing and i'd like some input from you guys. Whenever i try to boot, the farthest i get is about 2 seconds into the loading screen... if i try to do a recovery, it just shoots me back to the selection screen. And windows says a kernel file is missing, but i can't get anything else to run anways so that's not really the main issueI've even tried to reinstall a system, but i couldn't get anything to boot at all, no cd's.. no liveusb's, they all just cut off at a certain point. Although, i was able to run a memory test and everything seems to be fine there... and i also have swapped out the hard drive with one that i know is working and got the same results with that. I don't know if it could possibly a virus, but i did reset my CMOS by taking out the battery and everything.
tl;dr?
Problem: Can't boot anything(in anyway; usb, cd, hdd) It just partially boots up about 2 seconds in depending on OS.
Hard drive is good,
Memory is good,
Possibly the motherboard or CPU broken?
So it partially boot the OS?
>i was able to run a memory test
You'll be able to boot anything off of a disk if you can run a memtest because a memtest is essentially an "operating system" in the grand scheme of things in the sense that it's got its own kernel and loads from disk.
It's a CPU/GPU combo, and i recently purchased them a few months ago so i could probably get a replacement.
Not really, it's able to get to the boot-screen and that's about it. For example, on Windows it will start the little glowing orbs animation, then cut back to the selection screen with start windows normally or run startup repair; on Ubuntu, it will just continuously be stuck loading.
This somewhat puzzled me too, that's why i thought i might have had a virus. At one point I actually got Ubuntu to fully boot off of a USB for a short amount of time too, but then it threw some errors and shut down. Any enlightenment on what this may mean? Maybe things were just slowly getting wrecked even more?
Windows gave an error saying a kernel file was missing, but this is obviously not the problem considering i tried other operating systems that i knew were OK and ran on other computers. Ubuntu just kept trying to load itself without any success, although in my earlier trials(like when i got it to load for a couple minutes) it did give me a black screen with a bunch of errors on it, the only one i can remember was kernel panic-not syncing: VFS: unable to mount root fs on unknown block(0,0)
Update: It seems to be that all my hardware is working correctly, but whenever one of the main system files is accessed when something is loading, access is denied. I should also include that this doesn't happen on other computers, only mine. Is this a virus? If so... how can i get rid of it, since i can't boot anything to erase it; I've cleared my BIOS so it isn't storing itself in there, which would lead me to conclude that it's storing itself inside the RAM as i don't have my hard drive even attached at the moment. Does this mean i'm going to have to by some new RAM? or am i just way off here? never had to deal with something like this before.
