Today I have been working on an Asus P5QL/EPU motherboard, CPU E6800 I think, powered by an XFX TS450 PSU with 2GB RAM and using ad XFX 6800GT 256MB graphics card with dual DVI (no on-board graphics).
no hard disk, I just want to check out the BIOS and see what it tells me
After some work, I got it to enter BIOS (F1 on start up). 1 beep as usual, which probably means RAM is OK, graphics good etc.
But after 0 - 20s the power goes down, I lose the display, CPU fan stops spinning, PSU fan stops spinning. There is a green LED on on the motherboard which tells me that the system is on, in sleep mode or in soft-off mode.
When I start up again it behaves identically.
What I am I missing ? What's wrong ? anyone, please ?
