Windows 7 Ultimate x64 Freezes. No BSOD.

[AlejandroQ]

Hi! (English is not my native language, I'm trying my best here)

I've had this computer for around 3 years. It's not in my plans getting a new one any time soon.

The thing is this: In December 2013 my PC started to freeze out of nowhere, no BSOD; nothing. Before that everything went just fine. Yesterday I formatted it, hoping to fix the problem. No, nothing.

The freeze happens when the system is idle (no action at all, I just iniciate Windows and leave it there) and when I stress it a little (HD YouTube videos and stuff like that).

I don't know if any of you've already had this problem. I'd really like to fix it, because it's extremely annoying and I need this PC in order to work/study/play.

BTW, these are my specs:

• CPU: AMD Athlon II x3 (3.05 GHz) -> 4th Core unlocked
• Graphics Card: XFX nVidia GT240 DDR5 512MB
• Memory: 1x2GB Corsair + 1x2GB Kingston
• HDD: Western Digital 500GB 5400rpm

Thanks!

I would think the hard drive is bad or going bad.

I see one thing that could cause problems. Your memory is two different brands. If the speed of them is different, that could definately cause a problem. Take one of them out and see if the problem goes away.

Is there a way to check if that's what really happening? Without testing Windows with other HDD

I'll try it, but I don't see why should that be the problem. It has been working just fine for over 2 years.
