    Hi,
    Earlier today my computer had a rather nasty shut down with no battery and then this started. I have checked around and I have done everything I can think of to see what could be causing the screen freezes including: Checking Processes for something hogging CPU, checking event viewer system and application for excessive errors, running memory diagnostics and running in safe mode but I have had no luck. What could be slightly more alarming is that I am fairly sure that this freezing problem is actually occuring outside of Windows, in the BIOS I could still notice the freezing. So yeah... Any help would be greatly appreciated, thanks.

    Does the freezing get worse the longer you have the system turned on?

    If you leave the PC off for a few hours does it last longer before any freeze occurs?

    If you can say "Yes" to both questions then it could be overheating and should be given a thorough clean out with compressed air.

    When you say "a rather nasty shutdown" please elaborate.

    No, it freezes very consistently.

    The freezing starts as soon as the computer is turned on, it even freezes before Windows is launched.

    By nasty shut down I mean the laptop ran out of battery, I forgot about that, turned it on again and then it completely ran out of battery as it was coming out of sleeping from the previous lack of battery.

    Follow these instructions to run the Disk Check routine. These instructions are for Vista and Windows 7 for XP it is all the same but just hit the enter key after typing cmd in the search box, no need to right click and run as admin.

    Please tell me what OS you are using.

    Ok, thanks, I will give that a go. I am using Windows 7 Home Premium 64bit. I am currently backing stuff up, it's got an hour to go so I will try it after that.

    Ok I've ran it and the problem is still there and it didn't find anything. Any other suggestions?

    Ok, I appreciate you have run Memory diagnostics but a more thorough way to check it would be to run the PC on individual Memory sticks.

    Disconnect the power supply and remove the battery. Locate and remove one of the memory sticks, put the battery back in, reconnect the power and run the PC. If the problem remains, repeat the operation with the other memory stick so you test the PC on each individual stick of RAM.

    Hey, good news! As soon as I took out the RAM it started working again. Just to check if that was the issue I plugged it back in and the problem was still gone. So could it have been that some dust got moved when I pulled the RAM out?

    Thanks very much for your help.

    Great result. Probably due to a poor contact, pulling it out and pushing it back in has cured the fault.

    And, your welcome.
