I have recently purchased a new PC (DIY) and I've been experiencing some problems with it. While I'm working the PC would suddenly freeze and I'd be forced to restart it. This can happen during gaming, web browsing, video playback and sometimes when I'm not using my computer at all (That's why I doubt it is a CPU load issue). However, gaming would make it worse (Freeze more frequently) Well, it occurred to me that maybe my PSU isn't enough and that's what is causing the problem Here are my specifications: - MB: Gigabyte GA-H77M-D3H - CPU: Intel core i7 - 3770 - VGA: Gigabyte HD 6750 1GB DDR5 - RAM: 2x 4GB Kingstone KVR1333 DDR3 - HDD: WD 1TB SATA3 And - PSU: Silverstone SST-ST50F-ES 500W Can you tell me whether this PSU is enough to power up my pc? And if yes, can you tell what is the actual source of the problem?
