[Hardware Issue] New Rig - Plethora of problems. Take#2?

Okay - my second attempt of posting this (apparently the other version was too long and came out simply blank.)

So, i dunno if this is the right place to put this, or the format to put a post like this so i'll just go with what's natural.

I made a new rig for gaming/general use and 3d design, construction went fairly smoothly and it booted straight to windows installation on the first press of the power button.
But after this the problems started to grow and i'm yet to figure out how to fix any of them, While i'm no computer technician i consider myself at a level where i can build and repair computers fairly effectivly.

Problems with the rig so far:
- Sound skips during playback of music/video, but not games.
- Extremly Sluggish fps/stutter in all games. (as compared to the expected norm from the hardware.)
- Bios not detecting ram correctly(a)
- USB Mouse (Logitech Mx Revolution) behaving very strangely.(b)
- Active/inactive windows (such as Firefox/Internet explorer/my computer) going to "not responding" for 3-10 seconds before recovering. (happens irregularly)

(a) - The bios detects the ram as 1066@8CL. it is rated at 1600@8CL (see specs for ram)
(b) - The mouse appears to stutter and freeze in locations of the screen, and become exceedingly more unresponsive under system load, at any distance past about 50cm from the reciever with no obstructions the mouse becomes extremly unresponsive to no responce at all by around 100cm.
observations (if relevant):
i have a device called "PS/2 Mouse" by logitech appearing in my devices list next to the "HID Compliant Wireless Mouse"(assumedly the MX Revolution), it cannot disable said "PS/2 Mouse", and attempting to uninstall it forced me to restart the pc where it installs itself again, forcibly deleting it's driver files from the windows folder causes it to reinstall itself as "Microsoft PS/2 Mouse."
When i try 'stretching' a window, if the system is under load or the window is a 3D game the mouse instantly stops responding and i need to mash the buttons to make it wake up/deselect the stretching of the window.
Pressing keys on the keyboard appears to wake the mouse during it's freezing states (though this could be purely coincidental)
when using the mouse in another pc it responds correctly and has an operating range of several metres.

In an attempt to resolve the issues of stuttering sound, performance issues and the mouse problem i have:
-uninstalled and reinstalled all drivers
-tried alternate drivers (where aquirable for most components)
-tried all 12 USB ports for the mouse
- disconnected all other USB devices.
- disabled all forms of Wi-Fi/bluetooth in the house.
-reinstalled windows 7 (but not tried an alternate operating system yet)
-disabled and enabled all processor functions in the bios (i wasn't scientific about it so i could have missed some or did this incorrectly.)
- overclocked and underclocked the processor/ram.
- reseated the ram and the cpu-heatsink (though there is no heat problems)
- dismantled my Raid0 and ran the HDD's as separate IDE mode drives, and back again.

None of these actions seemed to have any effect on the problems.

things i have considered though not done yet (purely for reference/inspiration):
- running the system on different configurations of ram chips.
- running the system with a different GPU.
- reverting the BIOS to an older variant.
- installing an alternate operating system.


I'm unsure if this is in any way helpful to anyone who has a greater understanding of these kinds of problems than my own, but i would appreciate the help.

Coincidently, this forum confuses the ---- out of me >.>

I'm not an expert troubleshooter, but I can give you my thoughts on what's happening, which hopefully will get some more info for others who are better at it...

I know it's not a boot problem, but this is a good checklist for when you don't know what's happening.

RAM: This could just mean it needs to be set at a certain speed. Just because the package says it operates at something doesn't mean it does it automatically.

Mouse: I originally thought the mouse's batteries were low, but you said it works right on another computer. I do know that my mouse originally had a problem with the receiver constantly searching for it, but that fixed itself quickly. It'd be helpful to know what load it begins to stutter at...

I'd almost suggest wiping all the HDDs completely and reinstalling Windows. Then before you start loading up the programs, see if the problems are still occuring.

Some questions: Does the sound skip when trying to play music and do other things at the same time? How many windows do you keep open? How many tasks are running in the background? What are the exact parts you used?

Without knowing the specs, I'm almost inclined to say that the computer simply doesn't have enough processing power to do everything you're trying to make it do. You're definitely heavily using it to multitask, which will cause performance issues if it's not built for that. Check out the thread "Step-by-Step Guide to Building a PC" for some the benchmarking/diagnosing tools there.

I had originally included the system specs, but the post software on this was being troublesome with the word count so i deleted large amounts of the post to try to get it to work.

i have since dismantled the pc and rebuilt it from scratch, taking great care in seating the cpu-cooler, this reduced the load temperature by 8-10°C, but didn't resolve any of the other problems.

Try removing all the RAM but one stick and see if it works smoothly. If so, that indicates a great chance that a) one or more of your RAM sticks has a problem, or b) funny things are happening because all six DIMM slots are filled.

So in that case, running memtest is in order ... also, did you set the RAM voltage to 1.65V yourself? If not, 1.65V is a non-standard voltage, so the motherboard may not be auto-detecting it properly, which happens all the time.

Basically, undervoltage to your RAM could explain just about all of your problems. So if you haven't done that, that's the first thing I'd check. If you already tried this, sorry; don't mean to waste your time. I just couldn't tell from the first post.
