Ramdom power problems

Sometimes when I turn on my PC, it stays on for less then a scond and aother times it turns on a boots up normaly.

I've replaced the PSU with a 600W (old one was a 300W) and the same thing happens.

Current PC:
- Asus Vintage V3-M3N8200 Barebones System, AMD64 (Socket AM2)
- AMD Athlon 64 X2 5600 2.90GHz Dual Core CPU
- HIS ATI Radeon HD 4670 IceQ 1024MB GDDR3 TV-Out/Dual DVI/HDMI (PCI-Express) - Retail (H467QS1GP)
- 4GB (2x2GB) PC2-6400C5 800MHz DDR2 Dual Channel Kit
- Seagate Barracuda 7200.11 500GB SATA-II 32MB Cache - OEM (ST3500320AS)
- LG GH22NS40 22x DVD±RW SATA Dual Layer ReWriter (Black)

Any ideas on why this could happen or how to fix it before I contact the company I got it from?

when you say it turns on for less than a second does it then power on normally straight after without you doing anything? If so thats one of the Asus board features after a cold boot called crash free bios.

No...

I unplug the power cable from the PSU for a few mins and plug it back in it powers up normaly.

Out of interest which 600w PSU are you using.......?? If its a cheap branding one then i doubt it would be really 600w!
