[Plastic_50]

the problem started the night before last. i was searching on amazon all of sudden it truned off by itself as i try to turn it back on it would just go black like i've turned it off, so i wait mins or an hour i turn it back on it goes windows error recovery i choose safe mode it went alright, this kept on so i restored it back factory thinking it would fix the problem it did but maybe once or twce it happen again but you gotta know after the windows error recovery/ safe mode went right to my desktop...
my laptop is a acer windows 7 64-bit Aspire/model 5749Z.. i could use the help i can get.. i hope its fixed by now.. thanks, any help would be appreciated, if i could i'd like to save money

Since it worked fine in "Safe Mode", have you tried running deep scans for viruses, malware, and uninstalled and recent updates or added programs?
