BSoD - mainly whilst gaming

[computer1]

I've had inconsistent BSoDs for the past year. I've never thought to do anything about it (worst decision ever) until today. They usually happen whilst playing video games but have happened whilst I've just been on the internet too.

· OS - Windows 7
· 64-bit OS
· Had the computer since April 2011 - not replaced any components but did add another 4GB RAM around a year ago.
· Never re-installed OS

· CPU: AMD Phenom(tm) II x6 1090T Processor
· Video Card: AMD Radeon HD 6900 Series
· MotherBoard: ASUSTeK Computer INC. M4A88TD-M EVO Rev X.0x
· Power Supply - I'm sorry I have no idea but I will spend some more time today to try and find that out, I have already spent ten minutes with no success.

Extra info: My computer is due a good cleaning out because the dust on the inside of it is ridiculous,dunno if this helps but thought I'd let you know.

Thank you for any help!

Unfortunately, your installation is counterfeit, you seem to have a OEM_SLP key on a retail motherboard, please format and install with a genuine key.
