according to symptoms there's 95% probability, that this is northbridge chip faulire. other 5% is CPU V-core PWM failure.
Also, shouldn't the vcore be higher than 0.94v? (Not that radnam has the ability to check it anyway, most likely...)you can check PWM-failure, if you check the presence of CPU voltage(it sholud be 0,94v)

lamo said:the problem is in the broken southbridge chip.lamo said:if your notebook keeps shutting down when you plug in the USB devices - the southbridge chip(fw82801DBM or NH82801FBM) may be broken and you need to replace it.lamo said:if Intel, it can be the southbridge problem. the USB contacts are going right into the southbridge chip(except 5v and GND of course ), thus, if you have shutting down device during USB connection - 90% that this is a southbridge faulty. the faulty which appears due to the statical electicity.lamo said:the southbridge chip must be broken. only chip replacing will helps youlamo said:the southbridge chip may also been broken. in this case - only the MB repairing or replacing can solve the problem.lamo said:try to remove hdd and cdrom. if the computer will show you the bios screen, so the problem is most in faulty hdd. if not, this can be the southbridge problem.lamo said:it can be southbridge faultylamo said:if you connect firmly HDD,CDROM and floppy and still the laptop doesn't want to boot - then this is southbridge faulty. only chip replacing will helps.
AFAIK, inspiron 8000 is Pentium4 based laptop.... so, 82801CAM(or 82801DBM) is your problem.lamo said:if you have 830 chipset(Montara), you have the 82801cam southbridge. if so - you'll have to replace the chip.lamo said:test RAM, test HDD. if they work fine, then laptop needs the reballing of southbridge chip.lamo said:try to boot from USB-stick. it seems, that the problem is with faulty southbridge. tell the model of laptop.lamo said:ssampath, i very suspect, that this is southbridge faulty. this is typical problem for this series of acer laptops. the laptop MB is really has poor quality.lamo said:ylli, this is southbridge faulty. ou can replace the MB, ot you can repairing it.lamo said:ylli, just tell him, that you need the motherboard replacing for Acer 5100 models family. this family has same motherboard, and the typical faulty - the southbridge(ATI SB460) dying. the symptoms are: non working touchpad and USB ports.lamo said:the problems in this compal platform are: dead southbridgelamo said:it can be southbridge faulty.lamo said:thus, if HDD shows errors during reading and writing, it can be some disturbances in the primary/secondary IDE channels IN THE SOUTHBRIDGE CHIP.lamo said:this is standart procedure for identifying the southbridge faulty. if you can't boot from USB flash drive - be prepared for replacing the southbridgelamo said:this is standart situation of southbridge burning via USB static electricity.lamo said:i suspect, that replacing the southbridge will be cheapierlamo said:common problems with southbridge faulty etc.lamo said:you'll have no luck with this model, because this compal board has too many development errors(cpu socket located too near to northbridge, too hot system of mosfets of CPU current, constant problems with KBC controller and southbridge).lamo said:i suspect southbridge failure
