Out of nowhere my laptop won't boot up. it powers on, fan starts, and the dvd drive works but the screen is blank (no power), no beeps, leds for the wifi and power are on and solid and it won't even start to the bios.. Computer suddenly won't even boot to bios after no changes computer won't boot, not even to bios, after losing power while running? new computer build won't boot! can't even get into bios!. Hello yesterday my computer worked perfect but now it wont even boot to bios. no beep codes either. when i press on, a fan( i dont know if its from cpu or graphics card) go on and off..
Not even the compaq logo will display, which means bios wont start either. so i cant boot at all, or operate the computer in anyway. this happened right after i installed a gig of ram, i was upgrading from 512 mb to 1 gig, they were 2 different cards, 512 each, and both had 189 pins.. Computer wont start (even to bios) ask question. up vote 0 down vote favorite. my laptop (lenovo g580) just wont start. i can't enter even to bios. with power supply everything is ok. i tried to boot wout battery. nothing changes. ram: 4gb. laptop is not overclocked. i also tried to replace cmos battery. again, nothing changed!. Computer won`t boot, can`t access bios. when you put in a card or have a computer component requiring too much power the computer will not start up right. then reboot. in your case, i even.
