My old computer was a piece of junk that finally had one problem too many and quit working almost completely. I'll spare you the details, but it prompted me to get the new computer I'm using now. Well, technically, it's refurbished, but it's so much better than my old one and it's been working great, except for one VERY annoying, very bad problem I've encountered over the last few days. For no apparent reason, it just "freaks out", and this has happened three times now with the third one being today. The screen will freeze and be filled with noise, mostly these greenish lines, and you can still more or less see what's on the screen through the noise, but nothing works, it's completely frozen. There's also a terrible static-y noise that comes from my headphones (I don't have speakers hooked up). After a little while of this, it shuts down.
I described this problem to the friend who helped me get this computer, and from some of what he read online, it seems the problem could be caused by video or sound drivers not being up to date (I updated the video driver with Device Manager, the sound driver didn't need an update) or a loose RAM stick, which I haven't checked because I'm not very knowledgeable about hardware. I did open it up for a quick check to see if anything appeared to be loose and didn't find anything, but again, this isn't my area of expertise.
I have noticed that my monitor, which I bought to replace my old one and was also previously used, has flickered a few times and an error message popped up saying something about it having a problem but was automatically fixed (I can't remember the exact wording) but I don't know if that means it's a problem with the monitor or the computer or both. I also have an old Linksys AE2500 network adapter that has had problems in the past where it stops working for no reason and has to be disabled and re-enabled and it's done that again a few times on this new computer. I tried to update its drivers too, but they're already up to date.
Anyway, I'll give you the technical stats on the computer now. I should also mention I've only had this for less than a week, it arrived on Tuesday. I got it because I was tired of dealing with computer problems and now it seems they're not over yet. Very frustrating. Here's the link where it was ordered from:

I can try to provide more information if necessary. Please help me out with this as soon as possible. The return policy on the website mentions "defective returns within 14 days of purchase permitted on this product", so I'd like to try solving this problem before then, so I'm not forced to just give up entirely and return this computer.
