My PC sometimes POST's and boots and other times it doesn't. And when it does get to desktop the computer freezes.
The PC is a new build (3 weeks old) and for the past 2 weeks, it freezes usually any time between the computer turning on to when it reaches the desktop, and so requires me to keep restarting the computer (average around 4-6 times) before I can use the computer normally.
Once it's turned on and working, the computer won't crash or freeze at all.
And it's gotten worse over the past week where sometimes it POSTS and sometimes it doesn't and after lots of restarts it reaches the desktop and works perfectly.
I am thinking it is most probably the memory, what do you think and may you please help me.
EDIT: I'd like to add that when it doesn't POST there's no image on the screen.
Here are my computer specs:
CPU: i7 920 @ stock speed
Motherboard: XFX X58i
GPU: XFX ATI 4890
Memory: some generic Micron, 3x1gb, here it is: MT8JTF12864AZ-1G1
PSU: Corsair 650w
