Genius needs to help! problems with my video card and system

Question

Hey guys! I'm going to post my specs first so that you get a good idea of what I'm running on:
MSI Neo2 LS 865PE.....MAT=Slow
Pentium4 2.4C.....FSB=233=2.8C hyperthreading enabled ~>1.55V
Corsair TwinX 1gig PC3700.....memory on "AUTO" in BIOS with timings at 3,4,4,8 ~> 2.7V
Radeon 9700NP.....stock speeds ~>1.7V
AlienX case with 2 fan400 watt power supply and 6 case fans
Zalman Alum/Copper heatsink fan
1:I've had this motherboard for a few months now. I upgraded my video card from a nVidia Ti4200(128meg) to a Radeon 9800 a month ago, but I couldn't get it working at 8X AGP, no matter what voltages I threw at it. I returned it for a Radeon 9700NP hoping that it would work, but it still won't.
I'm using BIOS 1.9 and since there is no option to select your AGP speed, I could only try using ATI's drivers. Once booted into Windows, there is a slider you can move to select you AGP speed. On my machine It says that It has performed some tests and has concluded that AGP 4x is the best for my system....but my system supports AGP 8X!
I've moved the slider over to 8x (which requires a reboot) at least 5 times with each card but the slider refuses to move past 4xAGP after the reboot.
2: My second problem: I had an old stick of KingMax PC3200 and decided to buy 3 more sticks. Unfortunatly, the 3 I bought did not match the one I had, so I only put 2 of the new sticks I bought into my system. Immediatly, My system would crash, lock up, files were corrupt, and I got PLENTY of blue screens of death with a long message containing: 0x0000007  with all these other numbers and "0"s. I did a search online and found out I had a hardware incompatibility problem. I never got this with my old stick of ram.
I returned the 3 sticks of Ram and replaced them with the Corsair. Put my new Radeon 9700 in, formatted my hard drive....and within 24 hours, my system locked up 3 times, rebooted itself 5 times, and gave me the same BSOD as mentioned above with the same long message.  
I didn't change anything except for the memory and the video card. I've been wanting to overclock, (thats why i bought the faster memory   ) but I'm not sure what to do at this point.
     I have my FSB at 233 but I'm scared to go any higher because of previous system instability at stock speeds. My RAM was running on 400 and MAT=Turbo with the most relaxed timings at 3,4,4,8.
I've given myself hours of sleepless nights formatting when my system wouldnt boot into windows; overclocking....etc. I NEED HELP. PLEASE. PLEASE. Anything could work at this point.  
     I'm trying to get more info on how to run my system at a 5:4 ratio, also.  
If anyone has problems like me or knows what could be the problem with my system, please reply to this post, it would help me a lot. I've been trying to fix these problems for a few months now so anything is greatly appreciated.  

Answer 1

Thanks a lot to you guys that responded. I brought my computer home this past holiday and I want to let you know where I stand as of now. I guess this thread is like my blog for my computer. I want to clear some things before my first post makes everyone confused.
1- I have only 2 sticks of memory in my system: the Corsair PC3700 TwinX 512x2
I returned the 3 KingMax I bought, and still keep my old stick just in case.
2- I am using the 400 watt power supply that came with the case. I read some reviews of the case and I know the reviewer did not have problems with the power supply. In my BIOS, there are some voltages it is weak on. Lets say: it it should be 5.00+, my power supply will be feeding it 4.96v or something like that, but I dont know, or think, that is a major problem...
3- My computer will refuse to boot if memory speeds are set at anything below 400. SO....if I want to use a 5:4 ratio and have to set my memory speeds to "333" in BIOS, my system refuses to boot.
4- This morning, I did manage to overclock my FSB to 250. Specs are as follow:
Memory Timing @3,4,4,8,4.....speed set at "AUTO".....MAT at "SLOW"
MY 2.4C's FSB was raised to 250 = 3.0gig  
AGP/PCI frequency: 67.xx/3x.xx (cant go any lower)
CPU voltage: 1.5500
Memory voltage: 2.75
Video Card voltage: 1.7
     Everything was fine for the whole day until I heard something click in my computer around midnight, and then seconds later, my computer froze and made a continuous beeeeeeeeeeeeeeeeeep. (you can imagine)
     This "click" and system crash has been plaguing me for months now. I dont know whay it happens. I was just using AIM when I heard the click and my heart stopped.
My memory speeds have been set to "AUTO" even at the FSB of 250. But I don't know if this still means my system is at a 1:1 ratio. I know the BIOS then adjusts the memory to work at 500 if my FSB is 250...so I assume it is?    I love 3gig, but somehow I feel that 2.8 is faster, since the FSB=233 running parallel to my memory, also at 233
A FSB of 250 is good enough for me, that's what I've been waiting 6 months for. If anyone knows how to set other ratios to achieve a FSB of 250+, please let me know, but as I said, my memory won't boot if its set at "333"
