Strange Asus a7n8x problem

Alright, first off, here's the specs:

Asus A7N8X Deluxe Motherboard
TTGI 420watt P/S AMD Supported, 210 watts combined across +5v and +3.3v
AMD Athlon XP 2700+ (retail)
Geforce 4 ti4200
IBM 60GXP 40 gig HDD
Corsair XMS PC-3200LL 2x512 MB
Crucial 256 MB PC2100 (yeah, I know about the corsair boot problem)

Nothing else plugged in

No boot. It turns on, no beep, nothing on my monitor, no messages 🙁

Swapped in my AMD 1600XP+, boots to bios, temperatures are fine etc...

Tried the 2700+ in my other old system, ECS k7s5a, boots fine (although at low clock speeds)

Also tried my Radeon 32MB DDR card in, same results across the board.

So, the proccessor and motherboard aren't dead, memory isn't the problem, the only thing left I can think of is power supply maybe??

Any other tips or help on how to get the 2700+ to work on the A7N8X??

THANKS!
 
What BIOS revision are you using? I would go with anything after 1002.A. Have you tried booting w/out the Crucial? If not, I'd pull the Crucial. If that doesn't work, pull the Corsair.

If that doesn't work I'd boot with the 1600+, go into your BIOS settings, and manually set your memory frequency to 100% or "Sync". Disable anything in integrated peripherals that is non-essential to booting (everything except for USB if you use KB/mouse). Save and then save and exit, then power down and put in your 2700+. Also try switching the FSB jumper, it should be default 266/333, try setting it to 200 or removing it completely. Disable the onboard SATA controller via jumper near your CMOS battery.

Try again with either the Crucial or the Corsair, but not mixed.

Make sure you aren't overclocking too much. My A7N8X Deluxe had boot problems when I OCed more than I could, toning down the overclock made all boot problems vanish.

You're probably doing this with no overclock... just checking to make sure.
 
Alright chizow, I'll try that out, it sounds a lot like the Corsair Memory problem, so I wouldn't doubt if it was some similar BIOS problem, if not the same one.



Also I'll probably update bios, currently using 1002a, so I'll put in the 1600+ and change up some stuff including BIOS (prob not till later, I have to take out the 1600+ everytime I need to test it out, so uhgggggggggggggg)

wish me luck 😛

 
There is a good thread in the motherboard forum here on the problems/solutions for this mobo. Also a very extensive thread in the Asus mobo forum on amdforums.com. Check them both out, you'll find out what you want to know. Its a great board but we're long past the days of the P2 when you could stick just about anything in a system and it would run.
