@jbohar, what is the SMPS you having?

@asingh, can't it be cause of some setting in BIOS? some motherboard have option in BIOS that turn PC on as soon as they get power. can't it be same case with OP?

[jerrin_ss5]

check whther ur power supply is delivering proper power !!
if ur mo-bo has on-board LED's use that to gauge it !!!

[jbohaj]

Thanks but problem is still arising. while running, sometime PC start automatically. Also PC Starts on Shut Down & if putting on Standby.

@ Sam: Power Supply is Tech-Com, Model - PSP 4500 (450 Watt).
Where in BIOS this setting is situated?

@ Jerrin: Please tell how proper distribution of Power Supply can be checked?
Also, IF mo-bo has on-board LED', then where it situated & on mo-bo & how to gauge it?

Please tell how to create a Image with Norton Ghost at this Post: -

the led placement for mo-bo differ for each brand !!
but in ur case i think ther's no LED on ur mo-bo!!
so now the only option is to check ur mo-bo with someone else's power supply !!!

[jbohaj]

Thanks jerrin.. I'll test mo-bo with other Power Supply. But from last 2-3 years, PC is running on 450 Watt power Supply. My friend has Power Supply of 650 watts, if I test mo-bo with that (650 Watt Power Supply). Can it cause harm to mobo or to HDD??

Also please see above Post URL Link regarding Norton Ghost.

Thanks.

At OP. For starters try to reset CMOS. Remove the PSU cable, and press the chassis on/off button for 2-3 seconds. Then remove the CMOS battery for 2 minutes. Plug it back ion and see if you can boot it normally.

[jbohaj]

Thanks Asingh.
1st Step: Are you talking about removing PSU cable from mo-bo??. if yes, this step is ok.

2nd Step: But my PSU have not On/Off button. Should I On/off UPS button at this point.

3rd Step: Pluck CMOS for 2 minutes.
4th Step: Fix CMOS in mo-bo.
5th Step: Fix PSU Cable.

Actually I am new to hardware so asking this. are you talking about these steps??.

[asingh]

Just do 3,4,5. Keep the power outlet connection remove.

Thanks.

generally higher watts PSU won't damage ur mo-bo but make sure the PSU ur gonna use is a branded one !!!

[jbohaj]

Thanks guys, your suggestions works.
Booting problems were due to faulty power supply, replaced it & all gone.
@ Jerrin: Now Champion named Power supply is running. Is it fine??.

[Sam]

^^ please stay away from PSU that reads: extreme, champion or super, etc. these names are used to fool the user to buy. drop that PSU & get a good one like Corsair (if your pocket deep) or FSP (for 2k & below). if you'll upgrade your PC to a better one, get Corsair or at least buy FSP Saga II 350W. its low cost & will keep your PC safe.
