Every one hour I get the following; (running Windows 7 64nit) 1. Computer freeze, even when PC is not doing anything Then BSOD but its few seconds so I don't know what error it was Screen is stuck on BIOS splash screen, does nothing, have to power hard reboot PC No minidump AT ALL. 2. Its been happening for last 2 days, if I leave pc idle, I come back to the pc error: Windows 7, "Repair your computer" Windows failed to start. A Recent hardware or software change might be the cause. To fix the problem: 1. Insert your windows installation disc and restart your computer. 2. Choose your langugae settings, and then click next 3. Click "repair your computer." Status: 0xc000000e Info: The boot selection failed because a required device is inaccessible. --- Pressing 'continue' seems to get stuck on the same screen unless I hard power reboot. * Reseat PC parts * Did PC repair Windows 7 (event viewer just says: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.) which isn't helping much. Anyone can assist the error I'm getting?
