Frustrating Booting Problems!Please Help!Anyone

[Amitava25]

Guys,I am going totally crazy with a persistent PC problem which occurs randomly and erratically,as stated below:

After I turn on my PC(only 4 months old) after a gap of ,say 5 hours,here is what happens in exact sequence:

1)I switch on the main power
2)I switch on my UPS
3)I switch on my Power Button
4)Power LED(Blue) turns on.
5)HDD LED turns on for .3 secs and then goes off
6)Monitor turns from Active Power Mode to Standby Mode.
7)All the Cabinet fans and SMPS,CPU and GPU fans are running fine.
8)BIOS does not go to post.System freezed.
8)Now I press the power button for 3-4 seconds.
9)Machine boots fine.XP/Vista runs fine.

I have changed my CMOS battery.Reset my BIOS.Even updated my BIOS with the latest ROM file.Problem persists.

Here are my BIOS details:
Model: P5Q-E
Version:2101
Chipset:Eaglelake
BIOS type:AMI
BIOS Size:2048K

Could it be a HDD problem?Could it be a problem with BIOS itself?Could it be a heat issue?

Please suggest as I've lost all sleep and peace of mind.

My SMPS is brand new.

My config:
C2D E7300 @2.66GHz| ASUS P5Q-E | Palit Radeon HD4870 1GB DDR5 | Corsair 800Mhz 2X2GB 5-5-5-18 | Seagate 500GB 7200.11 |Corsair TX 650W PSU

1)I switch on the main power
2)I switch on my UPS

What is the "main power"?

Its a normal wall power outlet,with Earthing.

So the power to your UPS is turned off when you are not using the computer? Hmmm....Do you have the monitor plugged into the UPS?

It's is very unusual to have a UPS plugged into an outlet that is dead.

Yes but I ran my old P4 machine with a 17" CRT with the same setup with no problems.Of course my new rig is power hungry but do you suspect that keeping the UPS turned off may be the culprit??What is the solution in that case?Keep the UPS turned on all day??

Guys the problem,I think ,has been solved!For the past few days,it seems that one corner of my Mobo had been grounded to the metal chassis,due to the nut coming loose.This led to voltage fluctuations and subsequent booting problems.Now the machine boots fine with a single beep everytime.

My question is:Is there a possibility that my Mobo,specially the condensers & capacitors situated near the grounded portion,has already been damaged to some extent?Is there any way to know if my Mobo is perfectly all right?

Guys,problem still not solved.Even after all this,I again get the same problem:viz BIOS freezes befpre even going to POST...and MOST IMPORTANTLY ,there is NO BEEP when it occurs.After I press the Power Button for some seconds,BIOS boots up normally with single beep.


I'm having nightmares.Please help!

Not when the system freezez.Its only when I restart the pc holding the Power button for a few seconds,when it freezes.

Have you stopped shutting off the main power?
