unresponsive windows and constantly crashing [Solved]

hi adam. i can not connect to the internet via wireless again tried it in safemode with networking which worked for a while but before i could send the reply it lost internet access again, the laptop ran exceptionally quick via safemode however. I have managed to find an ethernet wire so will complete all tasks requested using the wire instead of wireless from now. here is the log result, would you like me to rerun it now i have internet access?

ive had a break through, i tried windows updates with the Lan connection in and it did it with no problems at all, after the updates were installed the wireless connection regained connection and is working for now. the laptop is still slow to respond (like you said possibly the ram issue), the model is a satellite pro L450D-12x

quick update my wireless lastest for about 20mins then disconnected again so im back to basics with the Ethernet cable,

Hi Lisa,
 
Good news regarding Windows Updates. 
 
Whilst connected via WiFi, what is the signal strength ([external image: LiiPHDx.png]) like? Do other devices connected via WiFi also experience the same issues? For example, do you have a phone or tablet connected?

• Press the Windows Key [external image: pdKOQKY.png] + r on your keyboard at the same time. Type devmgmt.msc and click OK.
• Locate Network Adapters and click the corresponding drop-down box arrow.
• Locate Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC, right-click the driver, click Uninstall, followed by OK.
• Reboot your computer. Ensure you are connected to the Internet via Ethernet. 
• Let me know if Windows automatically searches for the Wireless driver upon boot. 

hi adam, when it connects to the internet with wifi its on full strength, but stays on for only a short time. all other devices in the house work well on the wireless, its a virgin super hub and ive never had any problems with it, i uninstalled the driver but windows did not search for the drivers automatically 

^{hi adam just letting you know the computer searched for the driver when i turned it on again and installed it automatically. it seems much better now}

Hi Lisa,

Thank you for letting me know.   There is no need to carry out the instructions in my previous post.
 
Providing you are not experiencing any issues (excluding potential slowness caused by lack of RAM), I think we are just about done here!
 
 
STEP 1
[external image: xZ2qgMOy.png.pagespeed.ic.8e3QqD36Fw.png] OTL

• Please download OTL and save the file to your desktop.
• Double-click OTL.exe to run the programme. Ensure all other windows are closed. 
• Copy the entire contents of the codebox below and paste into the [external image: x1wDyQ2v.png.pagespeed.ic.unfrBmDo4K.png] textbox.

  :OTL
  
  :Commands
  [emptytemp]
  [emptyjava]
  [clearallrestorepoints]

• Click the [external image: xj7yFJut.png.pagespeed.ic.-XScsp82bT.png] button.
• Let the programme run and reboot your computer if prompted. 
   

STEP 2
[external image: xAFZxnZc.jpg.pagespeed.ic.8db6OVtjOI.png] DelFix

• Please download DelFix and save the file to your Desktop.
• Double-click DelFix.exe to run the programme.
• Place a checkmark next to the following items:
  • Activate UAC
  • Remove disinfection tools
  • Create registry backup
  • Reset System Settings
• Click the Run button.

– This will remove the specialised tools we used to disinfect your system. Any leftover logs, files, folders or tools remaining on your Desktop which were not removed can be deleted manually (right-click the file + delete).
 
— Malwarebytes Anti-Malware will still be present on your computer. I recommend keeping this programme, updating and scanning with it once a week to maintain security on your computer. If you do not wish to keep this programme on your computer, you can uninstall it by pressing the Windows Key [external image: xpdKOQKY.png.pagespeed.ic.tmAgS1-k6q.png] + r on your keyboard at the same time, typing appwiz.cpl, clicking OK and searching for Malwarebytes.
