In all honesty, I don't what the temps should be in F. I always use C. lol
What does it say your GPU temp is?

But I'm really thinking your HDD is not the problem.
Still if your pulling up no directx dialog, that means the GPU isn't working, or the drivers aren't installed properly.
For a scan I use Malware Bytes and AVG

sorry it took so long, work and stuff.
