Specs: Windows Vista Ultimate, 2GB RAM
I am new user now,but i saw some solutions that makes me believe and trust on you that i can get 100% satisfaction solution from u.
About my Home PC problem is:
By the past 4 days ,Our PC is not booting when i press the CPU button,no LED light in CPU button,no fan sound inside CPU,nothing else.
When i kept this machine like this after 2 or 3 hours, when i comeback and see, our Home PC is booting up automatically and opening OS smoothly, there's no inbetween error or anything else, just running smoothly.
But if we shut down and switch ON the CPU after 30 minutes or 1 hour, the above same problem exists as we press the CPU button,it doesn't powers ON...but if we see after 3 hours , our PC is booting up normally without any error screen messages and opening my OS Vista Ultimate and also XP [dual OS]

Even i tried without UPS,directly plugged into wall power socket to boot CPU,nothing happened.

what might be the problem happening like this always, any SMPS power problem or in motherboard or in memory RAM card, or in Backup UPS or ...what exactly the problem it is happening everytime for us.

Please HELP US that i mostly trust U

If I understand correctly when you push the power button to power on / boot up your computer nothing happens? Then 3 hours later it starts on it's own?


I want to go like my grandfather did. Peacefully in his sleep. Not screaming at the top of my lungs like the passengers in his car.

A CPU is a chip that fits on a motherboard...your's is an Intel Q6600. The tower is NOT called a CPU & there is no "CPU button".

I don't understand what you're asking either. Are you saying the PC powers on all by itself after 3 hours? or do you have to let it sit for 3 hours & then it will start? It could be your CPU (Q6600) is overheating or your power supply is failing. BTW, we call them PSU, not SMPS. You must be from India.

Thank u for ur reply.
Yeah i am not computer related job doing work.
Yeah i learned from u now about PSU and CPU, i will keep on changing like u helping me to know about PC.
yeah I am from South India,TamilNadu.

My current PC system condition is below what i typed:
Actually my correct Power supply is 400W, sorry to say about 350W.
Also i want to mention about my motherboard that i saw a green light still glows in my motherboard without this CPU doesn't boot, also even when in working condition, my PC time also going slowly within this 1 year to complete my 1 st New Home PC system anniversay. How is it possible that my PC time changed slowly, always keep on changing every time .
My Latest situation is from sunday onwards , my PC didn't boot at al even when i press the CPU power switch button in the morning,then no boot up..
By the previous day i switched the CPU power switch ON in the morning, then in the evening at 5:30 only, my PC booted up and worked normally till my night sleep before go to bed. Then on next day[sunday], i cleaned my PC to remove some dust with soft brsuh, not by disconnecting all the pwer supply,just removed all the connection by the back of the components like monitor wire,mouse,keyboard,ethernet,speaker wire,..and also remove[unplugged] my 2 GB RAM memory card and put it back into same slot, didn't do disconnected Hard disk cable,DVD drive cable, and rest of the taht was connected to motherboard, ididn't touched it at all.
Then my PC didn't totally booted up till i waited for the evening and also by night time.
Till so far i didn't touched my CPU because of nervous and if i touch it didn't go wrong by major problem of afraid.
Tell me so far i told my PC condition now, what might be the problem exactly, then what i supposed to do now.
