Other than the problem with your wifi and the computer running slow and "wonky" you have not mentioned any other problems which would indicate a problem with your ssd/hdd other than what appears to be a possible botched installation which has the possibility of being ssd/hdd related. Personally I believe that running a scan on the ssd/hdd would be fruitless, but it won't hurt anything to run a scan if you are worried about this possibility. But there is a much simpler way to test this drive than going through what pcpunk has suggested. Since you are posting here I'm guessing that have a functioning computer or at least access to one. This being the case you can download and install SeaTools for Windows on the functioning computer, take the ss/hdd out of the problematic computer and either install it internally or via USB. SeaTools for Windows will scan the computer for any storage devices, all you need to do is select you drive to be included in the test. This is just as effective and is much quicker and easier.
Please download and run SeaTools for Windows
The download loads is a Zip-file, a program like WinZip
will be needed to unzip this file.
Before the installation begins you will be prompted to either Decline or Accept the terms of the installation, click on I Accept.
Once the installation of SeatTools for Windows begins you will see an image similar to the one below.
1. SeaTools for Windows will search for HDDs and SSDs on your computer. Please remove any external storage devices connected via USB ports.
2. Detected Drives will list the HDDs and SSDs found. Place a check mark in the drive box you want to run the scan on. This should be the drive that has the operating system installed on it, this is usually C: drive.
3. You will see Basic Tests toolbar above Detected Drives, move the mouse pointer over this to open the test options. Please click on Long Generic Test
4. This will start the scan. When the scan is complete you will see the result under Test Status , please post the results in your topic.
5. The test will indicate either Pass or Fail. Post the results of the scan in your topic.
6. Click on Help, then click on View Log File. If the scan failed take a screen shot of the Log File and post it in your topic.
As for your wifi, you need to set it up to a wireless network. You will find a good tutorial with pictures here
At this point I don't know if you are able to boot into Windows or not from what you have posted. If you can boot into the operating system you can and should do a Refresh.
How to do a Windows 8.1 Refresh.
A Refresh basically will reinstall the operating system, this will not affect your personal files if you use the option to save them. The downside is that this will uninstall all of your third party programs you installed. Windows 8.1 will place a list of removed apps on your desktop after refreshing your PC, I would suggest that you copy this list for a reference when you go to reinstall these programs.
Press the Windows key
and the I
key to open Settings
In Settings click/tap on Recovery, click/tap on Refresh your PC without affecting your files, then Get Started.
You will see a page titled Refresh you PC, click/tap on Next. On the next page click/tap on Refresh.
The computer may turn off and back on during this process, you don't need to do anything. The scan will display a percentage of its completion.
The other option would be to do another fresh installation.
One last question, Is this installation Windows 8 or Windows 8.1?
