Memory Hell - Please help

[Colonelx]

Hi, I have an Asus M2NPV-VM mobo, just fitted a new GFx card x1950xt and some new memory 1GB ****** ram, the problem is that in messenger the computer stops and I just keep getting this repeated sound, it happens during BF2142 as well, thought it might be the card but I Can't see any probs there (new drivers, accelerox2 cooler),

Any ideas why I am getting freezes with this odd sound (can't see any conflicts)

It just seems intermittent, I tried the 7.1 drivers for the GFX card but to no avail, and as it happens when using msn messenger I don't think its the card, possibly something else...just can't find it!
