Tried to boot computer into safe mode. Tried function 8 during startup, no success. Found out Windows 8/8.1 changed these settings. Tried holding SHIFT key while restarting. Didn't work. Eventually I figured out I had to do it via MSconfig using run command (win+r). Under boot tab I checked Safe Mode box then the Networking box. There was a box all the right labeled something to the effect of "Make boot settings permanent" that I left unchecked. I clicked OK and the computer restarted into the blue "ADVANCED TROUBLESHOOTING" screen which eventually led me to the "WINDOWS START UP SETTINGS" screen. After clicking restart it sent me to the familiar "ADVANCED BOOT OPTIONS" screen. I pressed the restart button on this screen.
Computer restarted however nothing popped up on my monitor. After a few minutes I shut down computer via long-pressing power button and restarted. Still nothing on monitor. Rebooted one more time with speakers turned up to see if I could hear Start-up chime. Nothing. Computer DOES get power, lights on PC come on, but no video/signal. No beeping of any kind by tower.
Computer:
HP ENVY 700-060
Symptoms:
- No video signal through any video-out port.
- USB keyboard no longer getting power after about 10 restarts (Caps Lock and Num Lock lights no longer cycle ON/OFF. plugged in to another computer and my PS4, lights work when plugged into another source, so the keyboard is not the problem). Tried all USB ports with keyboard. No power through any. Also tried flash drive that lights up when plugged in. Nothing happened when I plugged it in to any of the slots on computer.
Steps I've taken to resolve:
- Gone over all outside wiring, everything IS plugged in correctly.
- Checked all inside wiring. Everything is still intact.
- Unplugged/Plugged. Pressed power button while unplugged to drain all power and even removed and replaced the CMOS battery.
- Shorted CMOS pins by removing plastic cap
- Turned off/turned on.
- Tried F11 during what would be boot sequence to get to HP recovery menu. Still nothing.
- Downloaded and burned the Kaspersky Recovery Disc on my laptop and put in Affected Computers Disc Drive to see if that would somehow work.
- Tried switching output wire to other DVI-out to in case Safe Mode only allowed video-out through a specific port.
- Tried putting in another graphics card with it's own video out.
- Tried new DVI wire.
- Tried two other monitors that work with other devices.
- Tried booting without any SATA drives connected in case it was a bad drive.
Any ideas?
