Boot can only happen if I press enter.

Hello all. I have this weird issue with my PC. Every time my PC restarts (by force or by asking it gently) it is unable to start booting. When it restarts 1st thing that bothers me is fun noise. This was happening for a long time, so I am not even able to remember if my fan should change the speed or something after reboot, but to change it in that way so that its louder. 2nd that comes is monitor. No info on it, no bios info or anything. The led indicating it is supposed to be receiving signal from GPU is blinking, so monitor is black. No HDD led lights. Now here is the weird thing. If I don't press enter, or maybe any other keyboard key (I know mouse keys wont do the trick), it would stay blank forever. I remember that 1st time I noticed this I reinstalled my windows, checked if fans were working, CPU temperature and such, but it didn't help. Recently I have updated BIOS and I was hoping it would help but sadly nothing improved. Its not a big deal, but it kinda goes onto my nerves so I figured to ask wise people what it might be. Ill give quick overview of my system:

OS: Windows 7 32bit
MB: ASUS 5pkpl ss
CPU: Pentium Dual Core E5400@2.7Ghz
GPU: Nvidia GT 240
Memory: 2 GB DDR3 kingston
HDD: Hitachi 500 GB
500 wats power supply

I had some issues with CPU's fan being wrongly placed and PC would restart for obvious reasons, and, other than that I had no issues considering hardware since I got this PC 4-5 years ago.
I just remembered I dont turn it off quite often, so I figured to try and see if it happens also after power up. Well, it does. Now the problem info is complete, I think.

Thanks for reading this!

Check your boot order in BIOS.

Why my boot order? Its not that it gives me problem booting system OS, the problem is before that. I don't have issue with starting system OS but PC as a whole. Boot order is just fine.

Glad you have solved the problem.

Replace bios battery

Which power supply exactly? Brand and model

What funny noise is it producing? Like a beep? Does it beep once short or different?

Try onboard graphics without the other graphics card inserted.

Allrighty than, I have found an answer. And it was really by accident. Today I have gotten a broken PC to rebuild and reinstall OS on it from my friend. And guess what? It also couldn't start booting until I hit any keyboard key. Ofc, I used same keyboard as with my own PC. So, for some strange reason, the problem is in this keyboard. It is an really old keyboard, logitech idk what model. It had been spilled on with liquid xy times. From time to time it tends to bug, like, not registering certain keys, or failing to do proper shift+key functions. Who knows what it might be. I guess this minor problem would be resolved with new keyboard. Thanks helpstar for suggestions!
