(Pre-post edit: Thanks in advance for any help, and sorry for this wall of text. I've been elsewhere for advice but I get the same "Update your graphics drivers" answers without any real suggestions. Been to best buy and talked a bit with the geek squad guy there and he just jumped at my suggestion that it was a hard drive issue and pointed me to the most expensive ones there. So I figured I know at least ONE place where everyone is helpful AND knowledgable. Thanks again)
Heya everyone, while I was on vacation seeing some friends one of them who was getting kicked out of his house decided to give me his home built (in 2009) gaming PC since he recently had picked up a new one. It works well, and even runs some games that it only meets the minimum requirements for at fairly high fps. Overall I'm pretty happy with this machine, I'm certainly not going to complain about a free gaming rig. However, it seems to be having some trouble.
Info
OS: Vista 64 bit
Processor: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz (4 CPUs), ~2.4GHz
Memory: 6gb RAM, 2x 1 GB DDR2, 2x 2GB DDR2
Graphics: 2x Nvidia Geforce 8800 GTS 512 (SLI)
HDD: WD 3200 00AAKS-00L9A
My issue is that (as far as I can tell) the machine has some sort of hard drive problem. Games such as Killing Floor, Magicka, Team Fortress 2 and Sonic Generations that have relatively small maps divided by loading screens don't lag at all. In fact the only issue I run into at all is when some of the prettier stuff happens in Generations (on high settings) which I barely meet the minimum requirements for.
The problem comes when playing games such as LOTRO, APB: Reloaded, or other games that have a very large map that must be loaded in piecemeal. The game will maintain a fairly high FPS, 40-50, and then the screen will stutter for a moment. This stuttering is still present even at the lowest graphics settings, though in LOTRO options that reduce the number of textures being loaded in (such as disabling grass or other such things) reduces the severity of the stuttering, though only a minimal amount. The sound plays as normal while the screen freezes momentarily and continues. During these stutters the hard drive light flashes, though it may be a little ahead or behind. This, combined with the fact that applications take a while to open up and loading screens last longer than I'd expect leads me to believe that it may be a hard drive issue. Admittedly I don't know a damn thing about computers other than fiddling, troubleshooting, and weeks of reading up on what in the world could be wrong, so I'm open to suggestions.
Before anyone suggests it, I have updated drivers. I have tried not-so-updated drivers. For everything. I can safely assume it is not a driver issue. I have an updated version of DirectX, as well as every other download required by microsoft or by these games. There is no chance of spyware or viruses slowing the computer down, as I did a complete reinstall of windows to switch to the 64 bit version of vista when I first got the computer and bought an extra 4 gb of RAM for it. Before, when the computer had 4 gb of RAM (replaced two 1gb sticks) and a 32 bit version of vista the computer had the same problems.
I have tried my video cards separately and together, both with and without an SLI bridge, and the stuttering continued unabated. I have cleaned the computer thoroughly with whatever compressed air product they sell, and though the computer raises the temperature of the room quite a bit, it has good ventilation and the stuttering is present at the same level regardless of how long the computer has been on for.
The hard drive has been defragmented in the past two days
I do not know how to overclock, nor has this machine ever been overclocked.
I have run HD tune twice (while not in games) and scanned for errors in the hard drive. No bad sectors were discovered and everything else appeared normal, unless an access time of 15.9 ms is a problem since I couldn't find any data on that elsewhere.
Well that was a lot of text, but this problem has been going on since New Year's and despite a lot of effort I can't seem to fix the problem. If anyone with knowledge of computers can offer suggestions, advice, or ideas for what the problem could be or how I could pinpoint it. Also, since this computer was given to me I'm not quite sure what parts are going to need to be replaced soon, what is outdated, and what maintenance I'll need to do to keep it running until I need to replace it?
