[louisoh]

first off... i nvr install wat not or did anything new.. but just out of a sudden one day, the PC would beep and auto restart when i was gaming.. actually not limited to gaming.. there was once or twice tat it also restarted when i was @ desktop. No BSOD or wat (and yes, i already uncheck the auto restart on error thing in win). Tried to troubleshoot abit then PC totally cannot on at all...

Next day frn loan me a PSU (sld be working de)... plug into comp. cannot on at all... dulan, switched back to my own PSU.. then can now on... test to run games last nite for 2-3 hrs.. no restart.. FUGGGgggg... so now what is happening? like all ok liao.

Shutdown system.. then PC off liao but cpu fan still running + CPU light still on. everything else off liao...

So what is wrong? PSU? or mobo...

TS, do list down all parts of your rig if those on the right isn't the rig having issue.

the last time i encounter this issue (power off but the fan, led etc still on) was with my mobo. took it back to the shop for servicing, sure enough its the mobo problem. Had to replace it but fortunately its still under warrenty
