Hi everyone !
My computer is Dell Inspiron 535, nearly 2.5 years old and heavily used since (almost 7 am to 11 pm everyday). It has not been "touched" by anyone or has had any other problems other than this.
For a few months, this is how I have to start my computer in the morning:
1. I switch on the power supply to ups, a green light at the back of the CPU turns on (monitor, speaker, etc. also turn on) I press the switch of CPU, nothing happens. (Fans etc don't start and no other indication is given by the CPU except the green light)
2. I switch off the power supply and everything excluding the green light of CPU turns off. The green light turns off in a while, and then I again switch on the power supply and push the switch for CPU. (Nothing happens)
I repeat these 2 steps a number of times (on-pushSwitch-off-on-pushSwitch-off....), and within about 15-30 minutes of trying the computer turns on (fans,lights get on and windows starts). Sometimes when the computer turns on, it makes a somewhat loud noise like that of engine starting (fans ?) and then it returns to making the usual sound. Everything works normally then, once it is on.
If I turn off my computer at this point and switch off the power supply, and turn it on say, after 15 minutes, it gets turned on with much much less effort and many a times in one try (which is what should happen)
Another thing is that if I keep my ups (and its power supply) on for the night (but the computer is shut down) it turns on normally the next morning when I push the CPU switch. (in one try)
Any idea what might be wrong ? (Switch/power supply unit ?) And is this something I can fix, or shall I call the dell guy only ? (Can I take everything apart in a dell computer just like an assembled computer ? I can see some rivets, I dont think I can take them out...)
Thanks a lot in advance !!
