Is this my psu going bad or hard drive failure?

I havent turned on pc in a while and when I tried tonight, the hard drives (RAID) would spool up then you hear them click and spool up again. It's like someone is turning on the computer then turning it off quickly. This just keeps repeating over and over. I can't get into the setup screen for the mobo as it shuts down immediately.

Try clearing your CMOS. It could be the PSU however.

(As you can see this is an older gaming computer I still use to run older simulations that won't work with Vista and store pictures so I may not boot up for a month or two at times.)

I switched out the psu from another pc. It did boot this time to show processor and memory test pass then it just stays there. At the bottom it says press DEL for setup, or Alt-F2 for flash utility-I DEL and nothing happens.

A few times after reset sometimes it might say detecting IDE drives but nothing happens.

I cleared the CMOS-no change

I swapped the CMOS battery and cleared CMOS again-no change.

I pulled out one memory stick and rebooted-no change

I pulled out the other memory stick and rebooted-no change

I swapped the slots and rebooted-no change

I unplugged all devices except for the video card and hard drives-no change

I unplugged my ps/2 keyboard and tried a usb keyboard-no change

Could the old psu maybe fried the bios chips on start up? I didn't smell anything like burning on start up.

Since my drives are setup in RAID could it be that? I don't know much about RAID but I assume a RAID issue would not prevent me from entering bios?
