Windows will not load with max memory installed

I have an Asus A7N8X deluxe Mobo 2.0 with BIOS version 1008 and running windows 7 ultimate 32bit. If I install the maximum memory of 3GB, windows will not load. When windows tries to load, it gives me options to repair windows or boot normally. I've tried swapping slots but no difference. Currently I have 2 x 1GB sticks PNY 3200@400mhz installed which runs fine from any slots. However when I add a third identical stick windows does not load. I have tested the new stick with one of my other memories in all slots and it works fine. I'm not sure what to do. Please any suggestions would be great.

Specs:
Asus A7N8X Deluxe 2.0
Bios 1008
Windows 7 Ultimate 32bit
barton 2800 clocekd to 3200 aggressive @ 2.21GhZ
Nvidia Geforce 6800GT Ultra
Corsair TX750 Watt
2 x 1GB PNY 3200@ 400MHZ


Thanks

Have you turned off your overclocking settings? In other words, try the new RAM with everything at standard/stable settings first.

you can stall 3.25 gigs of ram, if your running DDR2 ram, it wont like the odd chip like 1x2gig and a 1x1 to = 3 gigs I would say to you, install 2x2 gigs of DDR2 ram. to = 4GIGs, sure it will only see 3.25, but at last the slots will have matching chips.

same brand but does it have the same specs as the other one your using. heck i could have a PNY 1 GB and then go buy a PNY 2GB stick of ram and it could have problems. just reset the BIOS forst to defaults and go from there. also the ram stick you got may not be good for overclocking

This may be a more valid option. But is it easy to find 2GB sticks wtih specks of PC3200 @ 400mhz?

Not exactly...While the other two are PNY 3200/400, this one is called 'Super Talent' and comes equipped with a heatsinker. The specs appear to be the same

hmm well looks like it should be fine wow, do a memtest dude and if that doesn't work use a spare drive and install windows from start, usually if you change hardware when the kernel/drivers are loaded, you have to repair windows. have you tried to repair windows because that's what you need to do if you do change mb's processors or anything else. just the fact that there's a hardware change can spark this kinda panic. so install windows from scratch on a spare partition try booting up from it and see if that works.

Try running Memtest on the new stick of RAM. Have you tried just installing that one stick and booting into Windows? Does that work? It may be a bad stick of memory.

Definitely run Memtest, then. If the stick checks out, there could be an issue with the 3rd slot on the board.
