Ok, i started formatation, wipe harddrive and stuff, and then when I come back, i get some memory error then computer shuts down. Now when I turn on the computer It hangs at the first stcreen (i have emachines so it shows an e), for quite a while making weird fan and clicking noises. Then it finally goes through and back to the beginning part of reformatation (when at the bottom it shows the stuff it's checking drivers and such) and then stops at "starting up windows", while making weird clicking and fan noises. It worked perfectly before reformatting. How do I fix this? Is it possible to wipe the HDD somehow again? Thanks! Note - i also tried booting without cd in driver. Weird noises still then it says CANNOT start windows or smoething PLEASE INSERT SYSTEM DISK.
