I have no clue what happened. I went on a trip for a week i came back and now the computer will not turn on. I had this issue before so i replaced and resetted the cmos battery.Unlike the first time it would not turn on At all. I removed the battery and did a real time clock wipe and got it to turn on Mdos it said real time clock was lost hit f1 to boot. Before i could connect my keyboard the screen went blank and the fan kicked on high gear and i heard 3 beeps and could not get it to respond to anything to i unplugged it and waited 20minutes then plugged it in and now its back to not turning on at all. NOT A GOOD PRODUCT WILL BE CONTACTING CUSTOMER SERVICE TOMORROW
