Computer doesn't start (on first try) ?

[Carl-Fredrik]

Hello everyone.

So I bought this computer approx. 1,5 years ago and I've had no major problems with it. So suddenly a week ago or something when I started it it decided to get stuck at the first picture the screen shows...

NVIDIA GeForce 8600 GT
Press DEL to run Setup, Press TAB to display BIOS Post message

I tried pressing almost every key on the keyboard but nothing happened, so I turned the computer off again (by holding the power button for 5 seconds), then I restarted it and it showed the picture again for a second or two and then moved on (as it always have done).

I didn't think much about it, but then next time the same thing happened, and yesterday I had to start it three times!
It's not really a big problem to have to start the computer up three times but I'm afraid it won't start at all some day... Does anyone have an idea about what's wrong with it? :/

Thanks in advance.
