I turned my laptop on the other day to find windows 7 freezing just after login for no apparent reason, after running multiple memory tests, disk checks, various tests in recovery mode it eventually fixed itself despite no problems being found, whilst working I ran tons of scans, anti- virus, spyware, malware nothing found The next day the problem returned and has since stayed, it loads fine, will log in fine though on attempting to run anything it will just freeze, sometimes the start bar will load frozen, I have tried leaving it and still the problem persists, I am unable to run safe mode, it will run through the loading process get to the end and instead of loading safe mode will hang until it finally just loads up in normal mode I'm currently running ubuntu on an old 40 gig hdd that I thankfully installed on it a while ago, I have tried connecting my normal hdd externally and everything seems in order, and have ran tests for disk consistency with no problems found I really don't want to have to system restore, all my music, documents, photos are backed up but it will be a pain to try and get my software back, a lot of which I dont even think I have disks for in my current location any suggestions are much appreciated thanks,

Hi, Please go to Event Viewer to check if any error is logged. Generally, system freeze can be caused by several factors: incompatible device driver, corrupt system files or software conflicts. To resolve this problem, I would like to suggest: 1. Update the device drivers to the latest version, especially the graphic driver and BIOS. 2. Repair the whole system files by using the following two methods: 1) Run a command: SFC /SCANNOW to automatically repair the system files. 2) Perform an In-place upgrade. In-place Upgrade is a special upgrade process to repair the system. In-place Upgrade will not affect settings like photos, movies, documents, etc. that are saved on the computer. Moreover, In-place upgrade doesn’t require activation again. a) Perform a clean boot in the current operating system. b) Insert the Windows 7 Installation Disc to your DVD-ROM drive. If AutoPlay pops up, click “Run setup.exe” directly. c) Click “Install now” on the “Install Windows” screen. d) In the “Get important updates for installation” screen, it is recommended to select the first option to download latest updates for installation, if Internet access is available. e) Check the box “I accept the license terms” to agree with the installation license and click “Next”. f) In the “Which type of installation do you want?” screen, click “Upgrade” to perform the In-Place upgrade. g) Then, follow the wizard to finish the In-place Upgrade process.
