Make sure your hd's are reading and writing in DMA mode. Bob Profitt has counseled on this fix for slow computer response many times on these forums:
So, this just started happening recently, and I have noooooooo idea what is going on.
OK, so no word of a lie, it takes my computer 24 minutes to get to the windows log in screen.
It's ridiculous. It spends 10 minutes at the windows logo with the blue bar bouncing back and forth, then goes to a blank black screen for a good 10-15 minutes, then proceeds to the login screen. Sometimes it doesn't even make it there.
Computer specs are:
gig of ram
512mb Geforce 7600 video card
80gb hard drive
I have run a spyware and virus scan and cleaned everything out, and still does it.
My BIOS is updated and all that jazz.
So I am running out of options on what the hell this thing is doing...
