3 years ago I built a budget gamer that has lasted me until now. Just recently I've begun to have trouble with it - it has trouble booting on occasion, and when it does boot it'll often freeze or hang on a screen for a while. Prior to these difficulties, it also refused to overclock - I tried setting the FSB at 1 MHz over the stock setting and it refused to boot, which was strange. CPU and RAM voltage were still on auto. I think the motherboard didn't like it for some reason.
I think I've narrowed the problems down to the memory and motherboard (I'm crossing my fingers in the hope that it's not the processor, which is out of warranty) - the computer boots with one stick of memory, but not two. Additionally, the overclocking problem started when I installed a new motherboard, so I think that problem is rooted there.
I have a few questions:
1. Is it likely that the problem parts I've listed above are the causes of the symptoms I've briefly described?
2. Are they worth replacing? They are each still within warranty, but the hassle of dealing with each company's customer service and shipping the parts back doesn't appeal greatly to me.
3. Is it time to just bite the bullet and upgrade? For $250 I can pick up a 3870K (a nice overclocking chip, from what I've heard), an ASUS motherboard, 4GB of DDR3-1600, and a new HSF - I'd probably hang on to my video card, hard drive, and power supply and just plan on upgrading the video card at some point (I don't really mind mediocre access times, and the power supply is awesome/overkill for what I have now anyway). I play PC games pretty casually, but when I do play I like to see good frame rates on max settings at least a 720p resolution (I suppose 1080p is preferred, as that's the native res for my monitor). Buying, overclocking, and tinkering with PC hardware is a minor hobby of mine, so having new stuff around would be a plus, and I could always RMA the old stuff later on to build a second desktop.
