Problem starting PC

Hey
When ever I start my PC I have to press the reset button a number of times before it will start to boot.
It powers up,  all fans LCD etc turn on, but nothing happens onscreen.
This only happens from a fresh startup, if I reset the PC from windows/linux it never fails to bootup.

It is a self-build PC
Mobo Epox 8k7a
CPU 1700xp overclocked to 2000xp(I have brought it down to 1700xp but it didn't help)

This started to happen after I flashed the bois and put a new one on, and replaced my old athlon 1.4ghz with an 1700xp.

Any help would be great

Thanks

After you flash the BIOS,
 - have you set the BIOS settings again?
 - Try to go into BIOS setup and load either the BIOS SETUP DEFAULT.
 - Check all cable connections.

Good luck

Could be a power problem: less power is required for a warm boot than a cold boot, and your 1700xp probably draws more power than the 1.4.  Try removing as much hardware (hard disks, pci cards) as possible and boot from a floppy.  If it can consistently do so, I would recommend getting a bigger power supply (I recommend Enermax, because their higher current output) - if you can borrow one from somewhere and try it out, it won't cost you anything to troubleshoot.
