Bitbridge: what does a crash look like? X2: still need jbridge?

Occasionally the computer restarts without notice.
 
I figger it is prolly the sound card drivers, or the vid drivers. (no dump files)
 
But it occurred to me, given I use a bunch of 32 bit vst thangs, it may be one of these, and/or bitbridge.
 
So, what effects does a bitbridge malfunction exhibit??
 
And:  on the verge of purchasing jbridge.
 
Is bitbridge improved in x2 enough that jbridge is not needed? 

Go into Control Panel - System and tell it not to automatically restart on a failure. That way you'll get a white screen possibly with an error message on it. Otherwise you can go the the Administrative Tools and look at the Event Log. Its not often that you get anything useful, but occasionally you might. 

yikes! you did that yourself? that's heady, touchy stuff. so, be careful and do it small increments. a little goes a long way. i hope you at least did some googling. :-)

i was lucky, i was in warranty on my mainboard for a free "overclock engineer" support call over at asus and got one of the top pros there. i picked his brain for an hour while we optimized my bios. i was calling to solve stability issues with my pc resetting, like yours.

in addition to boosting the main voltage, another trick he shared was to disable all the intel speedstep, turbo boost and CE1 options. i had all of them enabled and my machine was resetting like crazy when i would put a load on it. after disabling, it solved it. you actually get better performance at a lower clock but full, all-core, continuous clocking than you do with turbo boost constantly turning on and off and bringing the cores up and down on the fly. while it sounds good in theory, in practice, DAWs like full-on, continuous CPU bandwidth.

with turbo, i got my i7 3770K up to around 4700! but with machine resets. i've got high-end liquid cooling with a quad, push-pull fan configuration on it, or i would not even have attempted any of this. so be careful. get some cooling.

when i turned off turbo, speedstep and CE1 i was able to get similar performance with my DAW at about 4200 overclock and no machine resets. well, it resets about once a week. i can live with that given the screaming performance i'm getting.

I wouldn't touch ANY of that stuff unless I knew EXACTLY what I was doing and what the possible problems are!

You could fry your cpu/motherboard in an instant.

BSOD's are usually related to bad drivers but can be a symptom of some other underlying problem, like overheating, bad RAM chips etc.

Take a look at your Event logs, both for System and Application, specifically for errors at the times your system is rebooting itself:
