|I just built a new computer for a friend using some inexpensive 1-2 year old components.|
Antec 650 case with 650 W powersupply
eVGA 750i SLI FTW motherboard
eVGA 250 GTS SLI
Kingston 2GB DDR2 800 (single chip)
1TB Hitachi harddrive
Symptoms: Upon bootup and installing Windows 7 64 it would freeze up everytime when it got to around the point of 'installing updates'.
Attempted solutions so far:
Changed the RAM voltage to 1.8 from the 1.9 that was autoset. Cannot find the timings on the chip or on the internet or calling Kingston. Set them to 5-5-5-18 2T (auto detection was 6-6-6-18 2T)
Result) I was able to install the OS but now it freezes whenever it comes under a heavy load (ie downloading a large file, installing a large program, or running a video game). This also occurs in safe mode but it seems less frequent.
2) Swapped out the video cards, and the problem still exists. Also tried swapping out the RAM, bumping up the CPU voltages, bumping down the CPU voltages, unlinked the FSB (1333) and the memory (800), underclocked the motherboard to 6x instead of 8x, updated the video card drivers, updated the motherboard drivers (software install, not BIOS update), also ran memtest86 on the memory for 90 minutes with 0 errors. All to no avail.
3) I tried to update the motherboard BIOS but when I download the eVGA 750i SLI FTW BIOS update and get to installing it, I get the error message 'No matching part number'. Also I think they have an error on their website because the part number in the program does not match the part number listed on their website.
QUESTION: Could I still be setting the RAM/FSB clocks incorrectly? Even auto/stock speeds are unstable. Can a faulty motherboard cause instability like this? Usually I would expect a motherboard to be DOA, not glitchy. Can this be the harddrive? It seems to freeze when utilizing the harddrive, but it's a brandnew drive.
