It obviously crashes faster if I run programs. It's not a reboot or blue-screen, it just flat-out dies.</P><P></P><P>Steps I've taken so far to try and isolate the problem:</P><UL><LI>Disassembled the computer and thoroughly cleaning it.</LI><LI>New HDD and latest drivers</LI><LI>New RAM (same kind as the original)</LI><LI>Tried without the battery / without the adapter</LI><LI>Running in safemode</LI><LI>Tried both different avalible BIOS versions (Y5-R02110Y5 and R0190Y5)</LI></UL><P></P><P>I've monitored the CPU temperatures and the results is: Idle, 46°C but after a while it suddenly jumps up to about 89 before the CPU fan starts and puts it back to ~46° again. While stressing the system, it will go up to 92-93 degrees before it shutsdown.</P><P>I've compared the temps to what's stated on intels homepage about the cpu and 90°C is what's stated there.</P><P>I've also noticed that the CPU voltages is jumping between 0.8750v, 1.0000v and 1.1250v. Not sure if that's normal.</P><P></P><P>BIOS ver. R0190Y5 seems to be for fixing unexpected shutdowns. My first thought was that when it installed the Y5-R02110Y5, that bug appeared, but then downgrading should've solved it?</P><P>According to DxDiag, my BIOS version is 08.00.10 but I'm guessing that is just dxdiag not finding the correct data.</P><P></P><P>I've searched the web for similar problems with the Vaio VPCCW1S1E, the Core 2 Duo P450 and GeForce 230M but I can't find any info about it, so <STRONG>any help, tips or solutions are very much appreciated</STRONG>. Buying a new CPU fan and trying is a last resort I'd rather avoid.</P><P></P><P>Thanks,</P><P>Jerry</P></BODY></HTML> Tue, 02 Oct 2012 17:22:17 GMT https://community.sony.fi/t5/pcs-accessories/vpccw1s1e-random-crashes/m-p/364906#M18832 randomavaliblename 2012-10-02T17:22:17Z Re: VPCCW1S1E random crashes https://community.sony.fi/t5/pcs-accessories/vpccw1s1e-random-crashes/m-p/364907#M18833 <HTML><HEAD></HEAD><BODY><P>Hi Jerry,</P><P></P><P>You have been very thorough with troubleshooting and the conclusion would seem to be that either the fan or temperature sensor that activates the fan is faulty.</P><P></P><P>If the temperature is reaching 89 before the fan kicks in I suspect a sensor problem but it may just be that the fan itself is faulty.
