Over the past few days, when I've come to turn my computer on I press the power button as usual but the computer won't turn on. The fans spin for a split second and the power LED continues to stay illuminated but thats it. The first day this occured I turned the I/O switch on and off on the back of the PSU, attempted to turn the computer on again and after a few cycles of this process my computer powered up as normal. Over the past few days this has progressively got worse like for instance today it took about 15-20 attempts to get the computer to power up. Once the computer powers up everything runs fine with no issues, I have temperature monitoring software installed on my computer and none of components are too hot either.
Any help would be much appreciated because I'm a little puzzled on this one and would prefer not to fork out for anything new until I've got a good idea what the problem might be.
Thanks
