Clevo Laptop Repair

This Clevo laptop was brought in as it was not starting up. It was running windows 7 home premium 32 bit and was locking up just before the desktop should have loaded. I ran the standard windows start up repair routine from the hard drive and it reported that it could not repair the problem, however, windows then decided to load properly. After a few tests all seemed to be working fine. I checked the windows event manager and it did not show any issues. I then scanned the hard drive for errors which ran fine. As a final test I took the hard drive out and installed it on the test bench to run a full diagnostic on the drive, checking for read and write errors. I also ran memtest86 for a while to check the RAM was not showing any errors and gave the fan and air vent a clean as it was looking a bit dusty.
