The high picthed noise could also be the power suppy moudule, these p/suppies sqeal when they are overloaded, as in a shortcircuit or similar fault. Like I said in my previous post, I see this all the time in at work.
Do as Dattodude said and check the spindle motor (the bit that spins the CD), though I doubt it would be this as motors generaly make a low pitched hum, if any noise at all.

I figure the power supply is not unlike a PC power supply with 12v and 5v lines. The 5v line on a PC is for the motherboard. Whereas the 12v is for the peripherals.

So I'd also guess that the 5v part of the power supply is toast. The whirring noise could be the CDROM part spinning up. Like PC cdrom's I expect if a CD is inserted the mechanism automatically queues the inserted data or music CDROM. I suggest pulling the top off the PS1, and pushing down the "cover closed" button normally pushed by the top when you close it.

Once you've pushed the button down, connect the power lead and turn the power point on.

Is it the cdrom part that whirring??

Next move would be test the power supply part. You might find some P/S output/wiring info on the net. Yes, you'll need a multimeter to test this.

Cheers,
Chris.

Sounds to me like something has gone shortcircuit in the PS1's power suppy (inside the unit). We get tv's,vcr's, stereo's etc coming into the shop all the time with this kind of fault. The good news is that it is usally repairable, though being Sony it might be exspensive. Anyway take it into a repair shop and see what they say.

jeez sorry but my typing has gone to crap, ever since i started using this site i type like ten times faster (with two fingers instead of one) but the mistakes are quite frequent, i might have to proof read just to ensure my posts actuall make sense

Yeah thats what I was thinking 1200RC! hehe

I have to agree with the fact that if the fuse was gone you wouldnt hear a whirring noise. Hmmm...I dont have a mulitmetre either but I do have a test light.

oh what a pity now youll have to but a PS2 with GT3

Sounds pretty weird!
Nothing else got stuffed?

An easy way to check the fuse is take it out and check for continuity with a multimeter or if you don't have one of these and you do got a test light check the fuse on your cars 12V battery with the test light!

But to me sounds like the fuse is good otherwise you wouln't hear anything from the playstation when you plug it in!

I had my PS1 plugged into a power board (those things that let you run 5 sockets from 1) which was on at the wall socket but the PS1 wasnt turned on and we had a black out. The PS1 now makes some rare high pitch wirring sound when you plug it into any power socket in the house. You can not turn the bastard on either. Press the button on the console and nothing happens! Im mighty pissed about it!

I thought it might be the fuse inside the console but I cant tell as the fuse isnt clear. Anyone got any ideas? This happened to anyone before??
