I installed additional 8 Gb of RAM on a system recently. Everything was running fine before I observed that the system randomly froze, I don't know what the proper term is, but the screen just hangs up on a static frame, and the PC, just hangs up. And it usually happens when I am playing games on it;
I took following steps to check what is wrong:
Updated all the drivers
Clean OS install
Removed the newly installed RAM sticks
Removed the old ones and checked with the new ones only
Removed any additional peripheral
Memtest, with no errors
Check disk, no errors
System file verification, no errors
One thing strange thing happens, when the system hangs up, my keyboard just powers down, and it's a Logitech G510, and with power downs I mean that it goes blank, and that is rare since even during crashes, usually the keyboard backlight is there.
The specs of PC are:
Windows 7 professional x64
Intel core i3 3rd generation(3240)
Intel Z75 based m-ATX motherboard(Intel DZ75ML-45K)
Nvidia 550ti
2*2gb ram sticks @1333(corsair)
2*4gb ram sticks @1333(transcend)
Microsoft wireless combo
Logitech G510 keyboard
450w cooler master smps
Htpc cabinet
The temperatures are within range during load; they rarely cross 70C
GPU stress test sometimes crashes the system, and sometimes goes on for hours without any crash.
Any guess what might be wrong?
(Sorry for not being able to give exact specifications of PC, and I hope this is the right section for asking such questions)
