Hello, my name is Cuffi and I have a problem with my All-in-One HP Desktop PC. Its HDD broke, and I saved money for 1TB HDD, that took 4 months, and the PC stayed in the attic for four month with its HDD place open. When It had no HDD it booted up and said, Error: Missing Hard Drive or something like that. But now when I try to boot it, the LED that tells that is turned on, just turns on for one second and turns off, thus the PC doesnt boot. Maybe the components are frozen? Please help, It took me 4 months to get money for a HDD, I cannot afford a new PC!
