okay so i just got my 2nd hand laptop, changed OS from windows 8 to 7, updated everything from windows as well as my drivers. But it just keeps on crashing every 30 minutes or so. Like it just shuts down immediately. At first i tried using windbg, but i didn't really get any crash dump files, as it wasnt a system failure crash. Shouldn't it restart if it was? I checked everything that i can do.
then i stumbled upon using sfc to check out anything weird with my laptop, and i found out that some of its system files are corrupted(?). I already uploaded the cbs log files.
waiting for further instructions.
