Hello, my pc Fujitsu P910 specs: I5 3470 10gb ram Nvidia geforce GT730, every time i start it up, i get beep codes, 2 short, then 4 short, after beep codes computer starts and boots to windows and works without any problems, i can not figure out what is wrong with pc that it gives me beep codes, it is really loud and annoying when i turn it on. Anybody know what it could be?
