Chosen Solution
Hi everybody, I try to cut to the chase. My Vaio machine has this issue for the last couple of years! and keep geeting worse that windows (7,8,10) restarts, shuts down or freezes randomly at boot, startup or in the middle of something. Sometimes with the slightest move or touching the monitor. I have tried the thing below: Cleaning the fansUpdating to the latest driver updatesUpdating BIOSFresh installation of Win 7,8,8.1,10 MANY timesInstalled Ubuntu (working just fine but it’s linux)Changed the HDDTested the RAM and changedTested with different chargers and batteries Until recently when I was fed up with Ubuntu and its lack of software, I installed Windows after many tries and learned the windows only boot if the laptop is physically “warm”! But Ubuntu just works fine if the machine is cold! For now I have to leave the laptop is BIOS for like 10 min until the fans go crazy and then I know it would boot to Win!! What’s your guess or recommendation to try? I appreciate your time for reading and helping me, in advance.
This is indeed a weird one! One thing you haven’t changed is the CPU. Maybe Windows uses certain instruction set extensions that Linux doesn’t bother with. I presume both Windows and Linux are 64bit (or both 32 bit)? This laptop is 5 or 6 years old so maybe you could get a replacement CPU (or entire motherboard) relatively cheaply, but you have to be scrupulously careful in reapplying the heatsink thermal paste or you’ll end up with the opposite problem, of failing when it gets hot! An interesting experiment would be to download and run Speedfan from almico.com and look at the CPU temperatures. Then go into the power settings and set it to the lowest power mode. Does it then crash when the CPU temperature drops below a certain level? Is it always warmer when you eventually manage to boot it up from cold?
