My computer gives out strong smell like burning plastic so I took it to them for test and repair, while working totally without problem. They said the PSU has some blowing that I can believe because it's likely to be PSU failure that gives out smell. However he also said my mobo couldn't recognize some commands that might lead to hard drive data problems, he suggests replacing PSU ,mobo and hard drive
I really do not want to replace my hard drive because I do not want to bother installing windows again ,if I keep that problem drive as boot drive, my only concern is if it's would cause damage to any function of other hardware, i want to emphasize again I CAN risk file loss on that drive, since no important file inside, only a few common applications without any important data
