my computer starts up and after a few seconds it shuts down, and sometimes it runs but loding the start up takes very long it keeps on loading and loading.

Std debugging is to pull parts until the PC posts. When it posts it will beep. Then put parts back in 1 at a time until you isolate the failed part.

start with pulling all external wires including keyboard, mouse, network, video, etc. POST? no - pull all PCI cards. PSOT? no-pull all memory. Etc.
