This happened for a few months already, and it's gradually getting worse and worse. I would open my laptop, it would run for about 30 mins - an hour, and then it would shut down completely on its own. These few days, the time span between when I start up my computer and when it just shuts down has become less and less, to the point where it would just turn off after 2 secs of opening the computer. I brought it to the IT technician and he tried to re-image the computer, but it shut down half-way, and as the re-imaging process takes about 40 mins, the IT guy couldn't do anything about it. He said that it's most likely not a battery/AC adapter malfunction.
Also, I've seen to have a foreign virus on my computer. Four icons are tenacious on my desktop, and every time I dump them in the recycling bin and restart the computer, it just turns up again. One of the icons is a super mario guy. But my anti-virus/greyware/malware software couldn't detect anything. The IT guy said it's probably a icon derived from a Chinese website and he could only detect it using a Chinese anti-virus program. But the problem is, I can't install any Chinese software onto my laptop (it's English-based) without it causing more problems.
Any help/suggestion/ideas would be most appreciated. The technician suggested me to by a new laptop. Any other alternatives??
