My computer is currently stuck on a black screen with a blinking cursor in the top left hand corner. I tried rebooting from a bootable disk and from a bootable flash drive and neither one worked. My machine is an HP Pavilion Elite HPE-110f. I am running on the 64 bit version. Has anyone run into this problem before and if so, is there a solution I can try on my own or am I doomed to take it to a tech?
