HP Pavilion dv7-1120ew Entertainment Notebook PC
Microsoft Windows Vista

Hey, I have a problem with my old notebook - HP Pavilion dv7-1120ew. Long time ago, my grandma have been using this device, but one day it has stopped working. Now, I got this in my hands, so that's the issue:
Notebook starts just normally, but... that's all. It's not booting, giving any beeps or so. Whrn I click the power button, vents are starting spinning (one time they stops after a few seconds, and other time after restart - it's working constantly, it depends, that's kinda strange), HDD is also working, but the screen is blank, Caps and NumLock LEDs are blinking (blink - 3 second pause - blink - 3 seconds pause - blink and so on, constantly). CD-ROM is working, USB also. I don't know, maybe it's BIOS issue, maybe CPU, GPU... Or maybe whole MOBO. Does someone have any ideas how to fix it?
