|Old basic PC was working fine at friend's house, they moved house, gave it to us and now it won't work. ("CyberCel Computer Systems" Pentium Intel Inside)|
So frustrating, can't see into the computer to see what's going on. Any ideas? How can we tell if hard drive is dead or just a simple step away from being useable?
PC tower starts up OK and hums along, then if I connect the monitor power-cord to the tower the monitor then shows a "self diagnostics" screen which appears and that says "check signal cable".
So then we connected the monitor's 15 pin male cord into the computer's 15 pin female, expecting to see the computer's start-up screen.
But no, the monitor suddenly goes blank and the power light goes from green to flashing orange.
The monitor definitely works, attached it to my laptop ok and viewed that computer just fine, (although I did have to change the laptop's graphic settings from single displays to multiple monitors). But the desktop wouldn't be having that issue, as it only has the single monitor I'm trying to connect.
Also, there's a tubular lock at the front we don't have keys for, but we've managed to move it to the other position yet it doesn't seem to make any difference to the startup lights and noises on the tower. Should we have that at 2 o'clock or 4o'clock?
Can we diagnose / rescue this machine?
