Hi Guys hope you can help me on my happy problem... Got Toshiba Sat Pro and Acer Aspire, both having the following issue: With/without battery *Shuts down seconds after turned-on, and sometimes it arrives at Windows 7 logo and desktop but still unfortunate. Tried doing these fixes but still unfortunate. 1. Clean fan. 2. Put new thermal paste 3. Reimage (still shuts down, so not resolved) 4. Replaced HDD 5. Interchange RAMs (checked thoroughly and cleaned) But here's the confusing thing, when I tried backing-up the files using "Hirens - Windows XP", it does not shut down.....waaaaaaaaaaaaaaaaaaaa!!!! Please help...Thanks and more power to TechSpot!!!! God bless you guys!
