So after about an hour it did say "starting windows"? Borrow a win7 install dvd. or let someone create a "win7 system repair disk". Try to boot from, just as a test

Perform a memory check from some recovery environment

yeah. i'll try that if possible. Appreciate your help mate!

You do not have to mess with a brand new computer that causes these problems because the retailer will replace it, or your 1-year manufacturer's parts and Tech Support warranty from Acer will cover it for you via phone or email.

If you prefer DIY solutions then follow theog's steps below, or get a superior clean reinstall following these steps: Clean Reinstall - Factory OEM Windows 7

I would return to the Retailer for FREE replacement or FREE repair.

Have you tried pressing <Alt+F10> at boot up, to goto the Acer eRecovery Management.

okay the error code is: ***STOP: 0x000000F4 (0x0000000000000003, 0xFFFFFA8005C4D400, 0xFFFFFA8005C4D6E0, 0XFFFFF8000318B5F0).
i'm on my way of installing ubuntu onto my usb and make it a bootable flash drive.
Thank you all for helping me. I'll keep posting as i go along.

The F4 Stop error only occurs due to hardware or driver issue, so if you want to try to repair it I would first test the hardware, then try booting into Safe Mode to determine if a driver is in error in Device Manager.

As in every case of unbootable Win7 I would also scan for malware and attempt repair of System files if malware is found.
