1st computer-Sony vgc-RB30 win7 ult.- intel P4 3.0, 2.5gb RAM
2nd comp. Compaq sr1800nx win7 ult.- intel P4 3.0, 2gb RAM
While making a call using Magic Jack, the Sony shut down and tried to reboot with a blank screen.
I unplugged MJ, turned it off and it did eventually reboot.
I plugged MJ back in and the comp instantly shut down and would not reboot.
It would not post and the Chassis and CPU fans were very fast. NO beeps.
I swapped the RAM, PSU, CPU and reset CMOS with no effect.
Still not believing a USB device could cause this, I turned on the Compaq and plugged in MJ.
BANG! THe same thing instantly with the same symptoms.
Does anyone have exprience with this or know how to revive the mobos?
**footnote- MJ was connected to comp1 via an extension cable. To comp2 directly. THX
