I have just change my bad motherboard for a new one: DX79TO.
Power supply, HDD and GPU card are all working.
My previous motherboard was using DDR2 RAM
My current spec:
RAM: Kingston DDR3 2GB(1 slot)
HDD: Hitachi 500GB ATA 3Gb/s
GPU: Geforce GT 620(2GB RAM)
CPU: Intel Xeon E5-26xx
PSU: 500W
All drivers installed and updated.
My problem am experiencing is that the PC is very slow. WIthin the BIOS menu, it takes around 2-4s just to slide from menu to menu. I have formatted my HDD and install a fresh windows 7.
The PC turns slow when installing windows, extracting and installing software. The CPU usage vary from 10%-30%(Temp 70C) and the RAM >90%. (On idle CPU is 0/1%)
When I restart my PC, it always shut down. I have run several test but can't figured out what the problem. The only thing that I have not tested is to use a larger RAM. From now am using ReadyBoost from a 4GB pendrive. Does it matter to connect the Power SW/Reset to the motherboard as there is already on the motherboard ?
