Sony Vaio PCV RX514 high pitch whistle and flashing on/off switch

I have a client who owns a Sony Vaio desktop. After the machine has warmed up it emits a high pitch whistle and the on/off switch flashes between orange and blue. At the same time the computer slows down. It's particularly bad when the computer is working hard - but this problem exists even when the machine is just running Word - and it's worse in hot weather. Sounds like an overheating issue but interested in anyone's opinion and suuggestions.There's enough RAM 512Mb. Phoned Sony, but this drew a blank (hah!).

Where does the whistle come from? External speakers? Internal speaker?
What model Vaio? Could the whistle be a continuous beep? If the pc has an IBM BIOS, a continuous beep means " No Power, Loose Card, or Short." If it's an Award BIOS, a continuous beep probabley means a memory problem.
If the whistle is coming from a malfunctioniong fan, check the PSU to see if the fan is spinning freely. Try swapping the PSU ( although this will be difficult because Vaios use non-standard power supplies). The problem with the power switch might imply a PSU problem.
Also try reseating the RAM. You could run a memory test with memtest:

Thanks for your quick feedback phototropic.
In answer to your questions; I've only heard the noise over the phone, but my client believes the whistle could be a continuous beep and does not come from a malfunctioning fan. The Vaio is a PCV RX514. The machine does have an Award BIOS - so I've suggested your idea of re-seating the RAM and running memtest, which I have sent to him.

Curiously, when checking for the BIOS type in setup,  the Hardware Monitor showed a CPU Temperature rising from 79 to 85.5 degrees celcius. And when it went to 81 the display went from blue to red!! This all sounds a bit drastic - but is it normal? CPU fan speed was 4,440rpm.

I've suggested opening the case and putting a domestic fan close to the CPU to try and cool it down - to see if this has any effect.

Thanks again - I'm not an IT person, just a mug who gets called on a Sunday 'cos I'm good with a screwdriver! Will be in contact again when I have more feedback.

Turned out to be a clogged vent above the fan that sits on the CPU! Thanks again. Now lets pour a beer and return to a normal Sunday.
