Without the HDD it should give a clear warning about not being able to find a device to boot from. If it doesn't, it clearly is some hardware error.
If it's still in warranty, have it fixed for free. If not, it might be an expensive repair. How old is the laptop?
Hello everyone. I have a laptop computer Dell vostro 14, that I reformated and installed new windows with windows 8.1, updated all drivers, everything worked well for a few days. But one morning, when i opened the laptop, it turned on by itself, and kept restarting again and again. I thought may be battery is dead, but that was ok. It keeps restarting, doesn't boot to windows, and the F1 setup (BIOS) key and F12 boot keys doesn't work too (like when i hit F1 or F12, it goes to the setup for a while but then restarts again and again), no bluescreen error, nothing, but only restarting and restarting forever util i close the lid
I have a little knowledge about hardware, so I unscrewed the case and tried to run it without the RAM stick, but it just keep beeping and doesn't do anything when i turned it on without the RAM. Then I unplugged the HDD, it gave the same problem again. I did the same with the cell, but that didn't help too.
I read a few threads which says it might be a problem in the cell, or some kind of virus, or videocard, but I have no idea what to do now....
