Laptop boots then shuts down after a few sec/min

Hey guys,

So I dropped my Asus EEE PC T101MT and the screen was cracked. That was months ago. It still works but not the touchscreen. I didnt not install an antivirus program and Im sure a lot of files have been corrupted and its very slow.

I used it for a couple of hours and then shut it down because it was so darn slow. Then the other day, I wanted to do a reformat. I turned it on and it got to the login screen and then it shut down. I turned it on again to open the BIOS settings so I can reboot it with my external drive for the OS installer but before I could save the new boot priority configuration, it shut down again! One time, I was able to make it to the "Windows loading files" part of installing but it turned off again.

So I gave it a rest for like 5 hours and I turned it on. I let it start normally. Got to the desktop and I copied some of my docs to the Drive D. Went on for a good few minutes, 5-10 minutes I guess but then it shut down again.

I really dont know whats wrong. Even if I try to reformat it, it shuts down while on process.

Is this a hardware problem? Or maybe some drivers are just really messed up.
Any ideas guys?
