Working on an HP pavilion 4445. (celeron 333). Friend was having weird visual glitches when he plays freecell. Figured just a graphics problem or Windows98 needed updated. Did all that, still problems. Switched cables on the cdrom because that wasn't working. Reformated to install 98se instead, but the cdrom isn't working right again. From dos prompt, sometimes "dir" on the cd will work, sometimes not. I got as far as windows setup before it stopped reading again. Could the controller card for that ide channel be bad? I tried hooking up the cdrom and hdd to the same channel (the hdd's one), but it wont get past POST or let me enter setup before locking up.
