Windows 7 turns off and then on when playing Roblox

[whateveritis123]

I have been playing roblox for over 4 years with the same computer i had until i started experiencing random shut down it started this year. my computer turns off when playing roblox after about 5-10 minutes and it turns black screen and then turns back on but i made more space in the computer case for the airvent to flow but i never started to try playing the game to see if it still has the problem. my computer is windows 7 and its from HP

After 4+ years, if it's never been done, the inside of the PC case may be ready for a good blast with a can of compressed air to shift all the accumulated dust & crud around the processor, fans and other components.

It's certainly worth doing, then see if the problem persists.
I give mine the compressed-air treatment twice a year.

From Amazon, this is what I buy for the job, 4 -pack because it's better value than a single can:
https://www.amazon.co.uk/Star-Duster-Compressed-Flammable-400ml/dp/B000O1HRHE/ref=pd_sim_sbs_147_3/278-4114791-7492410?ie=UTF8&dpID=41h01QFrafL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&psc=1&refRID=HQYWDXTZ2MRQZ379CFTZ

Or you can buy a single can: https://www.amazon.co.uk/Star-Duster-Compressed-Flammable-400ml/dp/B000MQ7DZC/ref=pd_sim_sbs_147_1/278-4114791-7492410?ie=UTF8&dpID=311jsRk1BrL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&psc=1&refRID=HQYWDXTZ2MRQZ379CFTZ

I buy four-pack because it comes in handy for all sorts of cleaning jobs (my electric shaver etc.)
