Last year I built the following system:
Mobo: ASUS P5N32-SLI SE Deluxe ATX - nForce4 SLI X16Compatible (NVIDIA nForce®4 SLI™ Intel Edition)
Processor: Core 2 Duo (2.9)
Chipset type: NVIDIA nForce4 SLI X16
BIOS type: Award
Hard Drives: 2X WD / Caviar SE 16 / 250GB / 7200 / 16MB / SATA-300
RAM: Corsair TWINX 2048MB PC6400 DDR2 800MHz Memory (2 x 1024MB)
Graphics: Two XFXGeForce 6800 Extreme 256MB, SLI, PCIe
Case: GIGABYTE GZ-XA1CA-STB Black:Aluminum SECC ATX Mid Tower
OS: Windows XP Professional
Ran like a dream for a year--no problems.
Problem 1:
All of a sudden, my two front USB ports stopped working (started to get those annoying Windows pop-ups that there is an unknown device). I opened the case, disconncted and connected the plug from the front chassis USBs to the MOBO and restarted, and nothing--the USBs are still dead. Any ideas where the problem could be, on the mobo or on the case? Anyone ever have this happen before?
Problem 2:
My Mobo has four slots for DDR2 RAM. I originally put in two and recently decided to add another two (paired) and bought exactly the same type (Corsair) that was already installed on the system. I know that this version of Windows will probably only recognize 3-3.5 gig tops, but I put in both new RAM chips. When I fired up my system and checked the memory, it still only listed the original amount of RAM (it's like those two new sticks aren't even there). I made sure they were seated correctly and that the clips that snap down to hold them were all the way down, so I know it's in there. Any ideas why the system would not recognize the additional RAM? I upgraded my RAM on other systems before and never had this happen.
