Hi and welcome to the forum
Take a look at this Post, specifically
POST #2, I just wrote for another user this morning with a Win8.1 problem. The troubleshooting steps are virtually the same, except you don't need to work about your Win7 as long as it has SP1 (Service Pack 1) installed. Here's the link:
Event error every thirty seconds (ID 16385)
If you cannot get into Windows on this computer, you should definitely borrow a friend or family-member or a co-worker's computer and print out these instructions, as they are nested links and so are 6-8 pages long on a printout. You can then have them with you in front of your broken computer. Also, it's very important that you read through the entire document which will require you to print out posts from 3 links; and digest it. If you can't wrap your head around it, I suggest that you take your laptop into your local repair shop and make sure you have a licensed Technician work on it. In fact, you need to ask the Tech his A+ license number or equivalent. If they don't know what that is, or forgot the number, or some other lame excuse, take it elsewhere.
Remember to post back all the hardware specs you can on the laptop, especially the
SPECCY report.
