Hey, Ace. Good to see you.Bummer on the crash.
There is a very good chance the Dell has a SoundMax sound chip, so it makes sense that those drivers would work well, as far as they go. The downside is that they support MME, possibly WDM (probably not very well), and no ASIO at all.
Is there better? Most definitely, yes, but here's the rub.
You can go USB (or firewire if your system supports it). On your system, they will offer good performance, decidedly better than the built-in card.
On your system, a PCI card, such as the M-Audio 2496, will offer superior performance.
However, it would most likey not be usable if you get a newer machine.
Note my system specs. i am using an older machine, much like yours, with a PCI card ( the E-MU0404). While this machine has served me well, I know her days are numbered.
Do you foresee a new system, or do you need to keep the current one running for a few more years?
As for the CD/DVD drivers, mine are all HP, and I can download drivers from their site.
If you know the Mfg and model #, you should be able to do the same.
If you have the original install discs, you can use those.
hth.
