Daemon Tools Wrecked My Windows 7 Computer

Yes, sptd.sys is well known causing problem in windows7.
You must uninstall that program and remove sptd.sys with SPTDinst.

I just went back and deleted SPTD from the registry. But it's still not working. Is it still because of the SPTD? One more thing: I had downloaded SPTD to uninstall it completely, but it keeps telling me that I don't have SPTD installed.

It's mean that spdt.sys has gone.
However if your windows still freezing, maybe there is still another problem beside it.
Do system file checker -> command prompt(as administrator) -> sfc /scannow -> enter

I'm running the scan right now.

The scan said there's no problem, but I ran a diagnostic startup and the startup failed. I just ran the startup repair and here's the list of problems it gave me:

If you removed the program via deleting registry strings, as opposed to doing a normal uninstall via Programs & Features, or the program's uninstall feature.... you didn't do a proper uninstall, which in turn may do more harm than good.

If you're going to delete registry strings (you shouldn't) at least do a proper removal first.

As to your problem.... you could try this....Repair Install

Before running Repair Install, then you might want to try restoring to a system restore point from before the time the problem appeared.

If such is not possible, then a Repair Install, using the procedure in the link provided to you would be wise.

System Restore - How to use

That works :)

1- System Restore - How to use, if problem isn't fixed, then...
2- Repair Install

But I can't get into Windows 7...I can only get into safe mode.
