Best Audio Interface suggestions

Hi Guys,  Back again after a date with the studio.  I am beside myself and could use your suggestions on this one.
 
I first bought the M-Audio Fast track Ultra USB and installed it.  X1(x) didn't really like it and I received considerable BSOD with it all with error reports linked back the M-Audio.
 
I returned it and bought the newest release Fast Track Ultra that came with Pro Tools SE ($150) more than previous audio unit.
 
I cleaned the system, re installed the new card, drivers etc.., At first thigns were going well.  Then I tried a couple projects gradually loading up the audio and midi loads.  I couldn't seem to get better than 4800 with 6MS with any stability or reliability of sound and quality.
 
Then after playing with several stand alones, Reason, FL10, X1c, Ivory II, I started to get rice crispies back.  I ended up having to re callibrate for each programme.  Ok, a chore but it was livable.
 
Today, I opened X1, played with Z3ta+2 found a really cool bass patch and cought the creative groove.  I set up to record the riff adn poof!, the Z3ta+2 kept reverting back to the Showcase sounds.  I couldn't get the patch I selected to stay when I tried to record.
 
Ok fine, Ill use another synth so I don't lose the feel and the riff I wanted to lay down.  I load the VST and Poof!!!! BSOD>.<
 
Error message again M-Audio error                    Reboot
 
Sytem checked fine, Raid came back up fine, no W7 error messages or reporting at all.
 
I loaded X1 again and got the error message (Guilib.ddl not found)  Frustrated I closed the error message and X1 loaded normally.  I could play anything.  I loaded FL10 and nwo more rice crispies.  Re calibrated and it was ok.  Go back into Reason/Record, no (Guilib.dll Missing) message.  Thats usualy what you get the message from from everything I have read so far.
 
So, my dilema and frustration is this.  Am I beating my head against the wall with this sound card?  2 Tries already returning and re installing for the same result.  My interest is in gettign a sound card that will be flexible, stable, and adjustable across all platforms of Software.  My specs are in my sig.  I would appreciate your feedback and any suggestions you may have.  I know X1 is still fussy, but that's ok really.  It's to be expected.  My son has the same card (older version of Fast Track Ultra) but he is running a 32 bit XP system and X1c and no trouble at all.  I bought him the producer version so we could share projects and collaborate without hassle.  Everything I have is literally brand new.  I built this workstation as my dream machine and now it is starting to feel more like a nightmare.
 
1)Soundcard of choice  2) GUIlib.ddl wth?  3) BSOD M-Audio related or X1c 64 bit issue?
 
Thanks for reading and responding.

it's all personal preference.. I had to change my m-audio ozone , due to their rubbish 64 bit drivers... 2 lots , 3 months apart and they were told the issues and worse than useless tech support. As you posted , you had problems on multiple progs, same here.. so the common thing was the asio drivers. In my case it wouldn't keep the buffer settings and just would give a bizare bit-crusher type effect. got a focusrite saffire 6 , no probs , worked out of the box.. I'd have got either a roland/cakewalk (didn't due to UK pricing at the time) or RME otherwise.

Unless you are as knowlegable as Jim (or get him to make you an integrated system), the simplest thing to do is try a different brand and see if that works if you are having a problem w/ an interface and teh company drivers.  Hardware wise, there ain't that much difference between brands, or enough to justify the pain and time involved in getting a baulky interface to work w/ your particular system.

Thanks for the posts guys.  To let you knwo what I have done so far and to answer your suggestions here is what I have done already prior to the new round of BSOD's.

1) FTU only plugged into rear ports main USB 2.0 direct to MB
2) I only use USB 3.0 for 2 TB back up drive
3) All sleep mode, power saving options turned off in Bios, W7.
4) CPU throttleing all turned off
5) Power SUpply is  Thermaltake, I already swapped out my older 600w Rocketfish, same issues.
6) Due to what I had read in other posts on the forum I never used High Performance mode ever.
7) Did a ram check fine, even swapped ram out from another system, same issues.

The only things I have not done so far is to disable the bluetooth on board for the MB, and remove the Wifi adapter from Dlink.  W7 has latest drivers as well the bios is up to date.  As with any new system this MB chipset is roughly 2 months old now and I expected hickups as new toys never come out solid for our purposes.

@ Jim ~  Please advise if after reading this I missed something and if not, which models of the brands you suggested whould be appropriate.  I plan on major workload in a standalone private studio.  Mostly solo work.  VST intensive with orchastra type track integration.  I want to run omnisphere, Guitar rig 4, Session drummer pro, Ivory 2, Traktor, Xphrase, Halion, and rewire Reason 6, and FL 10 all at same time if i want to.  As well have my bufddies come over and plug in their guitar or any other audio mono instrument and be able to load it in the mix as well.

Thanks for the read and your time.

I wonder if I can do this with my current specs?
