when i was operating my pc, suddenly the O/P to the monitor stopped and even if i hear to songs, function stops..Then not able to restart or even power off using the buttons-have to switch off the UPS to shut down the system.
When the O/P monitor is stopped, 3 fans & the processor green light keep working. so not sure what could be the problem.
Hence i cleaned the 2 * 2 GB DDR3 Ram and analysed. again the same problem. some time the O/P disconnects in 2 mins after booting up,10-15 mins while operating,30-45 mins. these are the variance of the problem.
I even checked removing video card and connecting to the in-built video slot to see if there is any prob in graphic card. Even after that the same problem persist.
There are 3 fans running in the cpu. one for motherboard, one for graphic card, one by default in the panel.
My system config:
RAM: 4 GB DDR3
Motherboard: Intel DG41KR
Processor: Intel Core 2 Duo (2.9 GHZ)
Graphic card/Video: Nvidia 9800 GTX DDR3 with 5
SMPS: Default with panel (250 watts)
Monitor: Samsung LCD 18"
