PC problems and solutions for the Toshiba Satellite L745-S4110

Problem: My PC takes a really long time to boot up, to open programs or to run applications.

Solution 1: There may be a number of reasons for this. I'd recommend trying the following:
1) Check for viruses. You can get plenty of free virus protection software, just Google "free virus protection" or something similar. If you're not using virus protection already I cannot stress strongly enough how important it is to get some.
2) Check free disk space. If your hard disk has anywhere under 20% free space, it takes much longer to do everything. It will not harm or damage your computer, it will just slow things down considerably.
3) Uninstall software you never use. Lots of programs start themselves when you start your computer even if you aren't using them. More programs running at the same time will slow your computer down.
4) Defragment your hard disk. If you have a normal hard disk (i.e. not a solid state disk) you need to defragment your disk regularly. Think of defragmenting as organising an untidy room - you can get things done more quickly if your computer doesn't have to search for them first.
5) Consider upgrading. If your computer isn't that old, you might consider upgrading your computer's memory or hard disk. Upgrading memory is fairly easy and usually gives your computer quite a speed boost. Upgrading your hard disk to a solid state disk will give your computer a massive speed boost in terms of booting up and launching applications, but it's a bit more complicated. Google them both.
6) Last resort - buy a new computer. If your computer is more than 5 years old and you have tried the steps above, you might want to just get a new one. My advice is not to get the cheapest one (you might end up having to replace it sooner than you want to) but don't buy more than you need. Simple advice - if you're going to spend a lot of money on a computer, Google some reviews of it before you buy it.

Problem: windows keeps freezing and sometimes it resets.

Solution 1: There may be a number of reasons for this problem. Typical reasons:
1) your computer is old
2) your computer is clogged up - defragment it and check for errors.
3) you don't have enough memory - buy some memory (check crucial.com for instructions on what memory your computer needs)
4) your computer is overheating, make sure all the vents are uncovered.
5) some other part is worn out - google how to test the hard disk, processor, memory, graphics and motherboard, or get in touch with someone who can do this for you.

hope this helps

Problem: My computer makes a clicking sound and it's very slow

Solution 1: URGENT: BACK UP YOUR COMPUTER NOW
It sounds like your hard disk is failing. It will probably become unusable soon and you won't be able to recover anything (documents, photos etc) on that disk if you haven't backed them up.

You MUST make a copy of your important stuff now before you do anything else.

Once you have backed up everything you might be worried about losing, you can try to get to the root of the problem. Try a free hard disk checker like Aeo3 HD SMART Lite to see if there are any problems with your disk. Even if it says that there are no issues with the hard disk, it might still have a problem.

If you have a damaged or failing hard disk, you should just replace it. You are unlikely to be able to fix it for less than the cost of a new one.

Problem: No picture on the monitor

Solution 1: Check that your computer is receiving power and that all of the cables are properly inserted.
If your monitor has a power indicator, is this lit? If so, there may be a problem with the resolution your screen is set to. After tuning on your computer, press and hold the F8 key. Windows should start in safe mode. From there you can change your resolution.

Problem: How do I do a factory restore?I do not have a disk.

Solution 1: Your laptop may have a restore partition which you can use to restore factory settings.

However, if this is not the case, you will need to download a copy of Windows 7 and install it on your laptop. Be aware that if you do this, you will lose EVERYTHING that is currently on your computer's hard disk. Your computer will run like new though.

You can find links to official Windows 7 downloads here: http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_install/cannot-find-digital-river-download-site/66a8439b-0d16-4b70-92f7-1c8486a46ebf

Please note that these are LEGAL downloads and that you will still need your Windows 7 product key (that should be stuck somewhere on your laptop, usually underneath and sometimes in the battery compartment). Make sure you download the right version as other versions won't work with your product key.
