Kernel Data Inpage Error blue screen appears once every 2 hours! HELP!

Hey everyone,

I have a ASUS windows 8 system (64-bit) I bought slightly more than a year ago. After 6 months, I got the Kernel_Data_Inpage_Error blue screen (like this image: ) once in 10 days or so. I neglected to address the problem then. Totally regret it! Its frequency slowly started increasing and today I got it almost once every hour.

It does not happen at start-up like I read in some forums but while I am randomly working. The error message appears and the system automatically restarts. I have a major presentation for school coming up in a couple of weeks and would like to fix this at the soonest.

I ran disk check on my C drive and it said there were some problems and I went ahead and requested a repair. Once its complete and I ran the disk check again it still says there are errors and I initiated the repair again. Not sure if its fixed this time. D drive had no problems. I also ran the memory diagnostics tool - no memory errors were found.

I really really appreciate any help I can get! Thank You in advance :)
