Ok I built my own computer about a year back and ever since I've been having trouble with it. After about three weeks the computer basically had a random crash unable to run so I reformatted it ran for about another three weeks and messed up again rinse and repeat longest I've gotten it to run is two months. Last couple of days it seems that it has gotten a lot worse basically reformatted about 5 times with two different windows discs. In fact yesterday I reformatted, downloaded all the windows updates, went to bed, woke up, went to download avg, and got blue screen. Basically I'm trying to figure out what the problem is. I think I've narrowed it down to the hard drive or my RAM. Common symptoms are random blue screens, webpages coming up as code, pictures loading weird (like part of the picture will be a big swash of purple or an assortment of pixelated colors), Games glitching, download files being corrupt, programs installing very slowly and other things. I'm running memtestx86 on it right now it's on its third pass and only found one error so I'm pretty sure it's the hard drive. I want some more opinions before i go out and buy a new hard drive especially with them being expensive now. In the computer I have AMD Phenom 2 processor MSI 760GM-P23 motherboard 4 gigs dual channel Corsair Ram Sapphire Radeon 5770 Video Card Western digital 500 gb hard drive 750 watt coolmax power supply Would really appreciate it if I could get another opinion.
