The notebook doesn't boot, neither from the HDD (Windows), neither from optical drive or USB flash drive (Windows 7 DVD or Ubuntu). It just hangs on a black screen with blinking cursor. No strange noises or clicks from the PC. Memtest passed correctly.
Testing with DIFS I get this error:
DIFS system code: 7EXW-XK7Z-3HSGC Serial: YL9Q372252
I'm pretty sure the problem should be the HDD, but I'd like to be sure before buying a new one. Can anyone help me interpreting the code?
Thank you in advance.
