Pc shuts down after 15-20 min ingame!!

[sanias]

Hello everybody!

I had some issues with my GPU( http://www.sevenforums.com/graphic-cards/305643-new-gpu-problem-pc-shutdown.html ) seems like i solved it but need problem occured.

After buying new psu ( Corsair CX-600) my pc had problem starting with all 4 DIMM Ram sticks ( GEIL Dragon Edition 800Mhz 2.0v 1GB x 4).Running 2 Ram's (2GB) opened my windows normally but when i put all 4 of them my pc doesn't start up and continuous long beeps heard from my Motherboard.Updating Bios to latest version didn't help but what DID help was setting DDR2 Voltage manually to +0.1v and +0.2v.My pc booted normally without any problem.After tried playing some games (Saint's Row IV,Dota2)and i get pc shutdown at 15min -20 min of gameplay.

PS.In past did Bios Reset.
PS2.Bios Updated to the latest version

Thank you in advance!!

1 long bleep from the mobo usually relates to the RAM.

try swapping out the RAM.

Run MemTest to check for memory problems before replacing it. Make sure to run for at least ten passes unless it throws up errors beforehand. Keep us posted with the results.
