    Hi,

    I'm running Windows 7 home premium 64 bit. My my laptop is about 6 months old with 8gb RAM.

    I have recently done a fresh install and ever since then I'm getting random screen freezes (it never happened before fresh install)... the mouse, keys, ctrl alt delete etc.wont respond and the only way out is to hold down power and restart.

    I thought it could be a RAM problem but I have checked with memtest with no problems found. I have also scanned with malwarbytes antimalware with nothing found.

    Can anyone give me any advice.

    Many thanks.

    Although it's had only about 6 months use, I would test the hard drive if only to eliminate that as a possible cause; somebody is sure to ask you to do that anyway sooner or later. It's normal procedure to test all the "usual suspects".
    Ascertain the brand of of your drive, then click the appropriate link on this page: http://www.tacktech.com/display.cfm?ttid=287

    Since your Windows is not running properly, you may have to download the DOS version of the testing software which runs from a bootable CD.

    It's an SSD so I'm not sure how to check for errors. I have run crystal disk mark and everything seems normal.

    Why did you need to do a fresh install on such a new PC?

    Was it Memtest86+ you used and how many passes did you complete?

    I only did one pass with memtest86+, do I need to do more?

    Please answer my first question in post 4.

    You need to run Memtest for at least 8 passes, it will take a long time and is therefore best set up to run overnight.

    After the install of Windows did you verify that you had loaded all of the device drivers for your hardware? Look in control panel > system > device manager and see if any devices are listed with yellow exclamation marks.

    Did you do the fresh install from a Recovery disc supplied by the manufacturer or a full retail disc. I'm just thinking about what drivers may have installed for the SSD or do you have these on a seperate disc.

    I used a full retail version disc and drivers from the acer website.

    I can't think of anything else that could be wrong. You just need to run the Memtest overnight and then if that passes I can only assume that the SSD is faulty.

    It could be any number of issues. Is it possibly overheating?

    I'm not sure... when I ran memtest the processor temps were getting into the 80's according to speedfan I'm not sure if this is normal (it's an i3 U380 1.33ghz) but the screen freeze can happen within seconds of startup or from sleep. What do you think?

    80C or F? If it is Celsius your CPU is probably frying.
