Hello,

Recently i changed my procesor from AMD Phenom 4x 955 BE to a 945 version (was trying to change the cooler but the 955 was glued on the old one so yeah...)

The change was done by a profesional(or not) personel in a PC shop. After that when I brought my PC back home and hit start button it has totaly shut downe after 5s... On my 4th atemp it finaly started normaly... But then it would ocasionaly shut down for no reason or always when trying to play PC games or watching wideos at 1080p. Enything better than minecraft will shut pc off or even minecraft time to time...

So what could be wrong is it the PSU wich I think it is (LC Power Silent LC5550 V2.2 550 W) or is it the GPU ( radeon 5850 - GV-R585OC-1GD )

Other specifications: http://postimg.org/image/zc9yyuh7d/

I have tried using OCCT and Furmark but got insta shutdown. Still trying to find someone to test my GPU but all of my friends have laptops and really old stationary PCs.

Please give me some advice and I am thanking you for all of your answers.

(sorry for bad spelling)

+ have the latest drivers, legal OP, and have done compleate system format and instaled OP (windows 7) twice.

Try putting a different PSU in it, maybe if you have another one or you could take it to a tech that does. If you think it's the graphics card then try removing the card and using your motherboard's onboard graphics. When you try the PSU you should have them check the CPU as well.
