Above link is from a google search. I don't know if there is a solution in there for you or not. I am wondering
1. Does this happen only when you're trying to play a game, or is it a regular issue even when you're just on the internet?
2. Are there any other symptoms? Anything else that you haven't mentioned or previously fixed?
I can't decide if this is a hardware or software issue but leaning toward hardware. I assume you ran virus scan, if so which program. Just in case maybe try malewarebytes. It can be downloaded at www.download.com
for free. If you have not run it and do not have it maybe you should try it just in case. Please be sure to update it right after you download it then run full scan. I would also replace the hdd sata cable with a new one., again easy and cheap, but I don't have high hopes it will solve your issue.
If you post more info we might be able to provide better help
Blue screens are normally caused by faulty memory or bad drivers, particularly video drivers. In your case I suspect that faulty memory was the cause of your blue screens.
In the case of the error “the hard disk can not be read” the fault is either the hard disk itself or its controller has gone faulty most probably the hard disk. I would go to the Seagate web site and download their hard disk diagnostic tools for your hard drive and see what the diagnostics tells you.
