I just boght a new system, which is as follows: AMD 2600+, Asus A7n8X mobo, Corsair single stick XMS 512 DDR 333, ATI Radeon 9000 Pro, Maxtor 80 Gb, Creative Labs Audigy. I installed the whole system and when l turned it on l could not post the Bios. I've tested the Video card, the Cpu and the hard drive and they all work fine. Is there a conflict between my memory and the mobo (do l need to use dual channel instead of 1 stick of DDR or is there a problem with my mobob itself. I am really stuck at this point. Any help would be greatly appreciated. Thanks in advance.

What power supply do you have? i don't think it's the memory corsair xms works without any problems on almost every motherboard,i saw a review about it. but it could still be the timings are too tight for the board,if that's the case you'll have to buy ram with higher timings or ddr266 will usally work with he same timings that 333 wouldn't.you don't need to use dual channel. how many volts does that radeon 9000 use? if it's 3.3v you can't use it with the 1.6v agp slot. don't know much about radeons..i've always had nvidia based cards.

No. I have this problem with my Asus a7v8x-x. Firstly the thing is set up to start in PCI graphics mode. THEN when you add hardware each time, it will stop at post, as it updates everything. Just SOFT reset (alt-cntrl-del) while you are on the blank screen, and it should get you past that. The other way I got around it was, use an old crappy 2 meg pci graphics card, just when I first put it together, to get into the bios and change graphics to AGP slot. I also have a Radeon 9000 pro. It works fine.

Thanks for all the help guys. Turned out it was a bad Mobo after all. Replaced the Mobo and now everything works perfectly. Thanks for all the ideas though. Who knows when they may help me solve another problem. Thanks again.
