Scandisk is a lot better than PNY in my opinion. I had 2 PNY flash drives and they both had issues and then I gave up on them.
If it's your only computer I would do the following
- Determine which disk (SSD or HDD) you want the OS on, the SSD would be better.
- Copy any data you want to keep to the other drive
- Download all of the drivers or at least the network card driver and put them on the data drive (the non OS drive)
- Boot to the Windows 7 disk

Click Drive Options at the next screen
If both drives have partitions on them add up the total size colums for each drive to determine which is the SSD. Once you know which is the SSD and provided it has partitions, click each partition on the SSD and click Delete. Then the SSD will be represented as just one entry as Unallocated. Click on it and click New and leave all the defaults. It should be 2-3 partitions, then click Next. It should install and then you just need to setup your user, programs and drivers.
