Do PS have a "safety measure" to not switch on if the PS fans have stopped? This might make sense, as an overheating PS could theoretically create a good bit of damage to the system.
JD, after the 10 minutes pass and the computer boots on, are the PS fans spinning then? I'm wondering if the ball bearing in the PS fans might have gotten dirty or off center, meaning that the engine is exerting pressure to turn but the fan is only turning intermittently. If it has a system shut off mechanism to prevent overheating, then that would account for why it won't turn on until the PS fan starts turning and will kick off if the PS fan gets stuck again.
Just a thought, again, replacing a PS fan is FAR cheaper than the PS, like $5 vs. $60-80.
When the system booted up and was working, the fans were spinning...but not since I had the computer at work this morning.
Right. I decided in my wisdom it was the power supply (after reading peoples thoughts and what I saw this morning at work trying to debug it).
So I've bought a new power supply An Artic 650W. £70. Looks very well thought out. It doesn't have one big cable with lots of "branches" where half won't be used. It has "sockets" on the back of the supply and you plug in the cables you require.
Fitted it and the machine is working...thanks for all your help.
I have a new issue...the keyboard does not want to work "all the time". By this I mean...
I have the BIOS setup so if I hit a key, the machine powers up...and this it does
However, when I get to the login screen, I cannot type anything in the password box.
HOWEVER, if I boot in safe mode and log in as me, I CAN type in the password!
Now I logged in as me in safe mode and removed my password just so I can get onto the system and this is fine, but I CANNOT use the keyboard.
I've checked the BIOS for some setting causing an issue, and I can't see anything mentioning PS2 (my keyboard type)
I've installed the drivers for my keyboard in safe mode.
So the keyboard works in safe mode, but not in normal boot up mode.
Any ideas please?
Once again, thanks for all your input and a special thx to the people mentioning power supply. I suspected motherboard, b
