I've builded about ten computer since the late 90's and my latest computer boot for the first time about 3.5 years ago.
I've had my share of hardware related problems but this baffles me:
Suddenly after I installed a game which was not compatible with Win7 (I uninstalled it immediately) the computer wouldn't boot and since then:
- If I start it up cold it will not boot every now and then, the blue power LED lights up and the red HDD LED lights up but nothing else happens, the screens don't get any signal, no beep, no nothing. (When the computer really boots from cold on the first try the red HDD LED does not light up) To boot the computer I'll have to turn off the power (by pressing the power button for 4 sec), wait about 10 sec and then turn it on and it will boot.
- If I do a restart it will never boot, I'll have to turn off the power and wait 10 sec to boot it "cold"
Last night my "normal" booting procedure didn't work. I tried two times but it wouldn't boot. Then I disconnected the power cord and switch off the main circuit breaker on the power supply and wait for about 10 sec, reconnected the power cord and turned on the computer and then it boot normally.
An other strange issue is that it seems the booting order had changed last time I checked BIOS and I hade a hard time correct it, might not be related to this problem.
Does anyone have any idea or had a similar problem that could help me fix this problem, I would be most greatful!
