have you or some friend "optimized" the laptop by disabling "unnecessary services" ?
Reboot the computer and log on with an Administrator account. Then go to this site and compare your services with what are listed in the DEFAULT column for the actual version you are running. Most of the defaults will be the same but several vary by version:
As someone else noted, that laptop tends to run a bit hot and heat can cause many various problems that might seem unrelated. ,ake sure its vents are clean and clear and that the fan is working.
okay guys, I really need help with my computer. I know the basics of working one but I don't really understand the super technical stuff so just please bear with me here. I have a Toshiba Satellite L755 which runs on Windows 7 Home Premium. Anyways, today my laptop randomly stopped connecting to my wifi. One minute it was fine, then I put it in sleep mode, went back on an hour later and my touch pad was frozen and where the wifi bars display in the bottom right hand corner, it's now just a white outlined box with a red X through it. It says "No connections available" even though every other device in my house is carrying on as normal and there's no problems, so I know something's going wrong with my laptop. I connected a mouse through the USB port so I'm able to maneuver my screen now, and when I click on the box with the red X, it gives the option to troubleshoot, which I've clicked, which then runs Windows Network Diagnostics. Right away it stop and says "Problem Found: The Diagnostic Policy Service is not running" and an option underneath says "Try these repairs as an administrator" so I clicked that and then right away it says the problem was "detected" but nothing has changed. I've never had any issues like this before, I didn't change any settings and the only thing out of the ordinary I've done recently was download iTunes/music last night?? Which they were running really smoothly and didn't seem to cause any issues at all. Anyways if you read this entire thing you're seriously awesome and if you could give me suggestions on what to do that would be so great.
