Just as the title says, my laptop keeps shutting off like it is loosing power. The computer started doing this about a month ago and has steadily gotten worse. The specs are listed in the link below and the machine is in the same configuration it came in from Toshiba.
I know it is not a power supply issue as I have tried a different charger/adapter with the same result. I also know this is not a cooling issue as I have checked temps while running bench testing software and the cpu rarely gets over 55* C. For good measure, I have tore the computer down twice to look for issues and cannot find anything? I reapplied heat sink compond and even replaced the apapter plug with no change.
Yesterday, I attempted several times to run MemTest86 on the computer to see if the RAM is causing the issue. Everytime I try the test the computer shuts off. The furthest the test has gotten is test #8 on the first pass, with no errors reported. I am unable to keep the system running long enough to get a full pass in.
What could be causing this failure? Could the RAM be bad causing this issue? How likely is it that the RAM has went bad for no reason after 5 years of use? How likely is it that RAM this bad not show any errors on MemTest86 through test #8 on the first pass. Could the mother board have some cracked solder somewhere that would take a magnifying glass and a month worth of searching to find? Could it be the processor or HDD?
I am a DIY kind of guy and do not know much about computers. I have already purchased another laptop to replace this machine. It has been a pretty good machine considering I purchased it just over 5 years ago and it has been problem free until now. With that said, this machine has been taken great care of, and never abused. When I opened it up the first time while trouble shooting, I was shocked how clean it was. However, I am taking it very personnal that I cannot find out what is wrong with it! Any opinions or insight is greatly appreciated.
