I have an Alienware PC with the full water cooling etc. When I switched it off last night I noticed that it was making a funny repetative pulse type noise so I switched off the power suply. When I came to switch it on this morning it wouldn't start it made the noise for a little while then nothing.

Your power supply has a theoretical Maximum output of 700 watts, but the problem is that the hotter it gets the lower that number becomes... It's obvious your power supply can't handle the power draw or the heat from the Graphics card when taxing it by playing games... Two things you should do:
1. Make sure you have more than just your power supply venting hot air out of your case... Adding a fan or 2 will help take some of the cooling stress off the power supply.
2. Buy a better power supply... Newegg.com is a place I get most of my PSU's. Read their ratings and compare specs. You will notice on that site that your particular model is not rated very high.
Greetings I personally like it when my fans are cooling at full speed all the time. That means it is cooling well. Now most computer fans are sensory thermostatically controlled fans. Which means they go on and off when the computer is cool and on when it gets hot. Now with this in mind. You may just need a simple blowing out of the hardware above the CPU might be packed with dust.
So first I would clean it out if you have not done so already if you have done so then I would go to control panel and click on the power options and set it to default. I noticed when I changed my settings away from default my fans stayed on. When I went back and set the power options to default the fans started going on and off during the hot and cold readings. This is just my computer efforts to solve this it is really not a problem if your fans are working full speed. However if you leave your computer on all the time note that this will wear them down sooner than they would if they were going on and off. Thanks for using FixYa! John
most power supply units will fit you can get a larger wattage output eg: heavy duty if you have added any more devices to your computer more RAM,a larger hard drive,more cd/dvd drives these added will put a greater need for wattage output on the PSU you should check all the electrical connections before you make a decision and make sure they are the same as as the ones that you will need to run your computer also check the measurements inside the frame to make absolutely sure it will fit you can get lots of PSU
The switch mode power supply in the desktop computer has failed. Most likely the capacitors in the power has exploded.
You need to open the desktop computer and remove the old power supply and replace it with a new one. Take the old power supply with you to your friendly computer shop and get a replacement power supply with the same wattage or greater wattage.
A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Hi, Are you able to test or repair some of this your self? is so use a multimeter and check the power supply,If you get no reading then remove the unit and open the cover, on the printed circut you will find a fuse either glass or ceramic. Replace this and also clean all dust from the unit replace the cover and reinstall in computer.
If this fails you may need a new power supply unit.
