Hello everyone,

now lemme continue with reference to this thread of mine

Unknown PC Problems

The story continues...

I got the PowerSafe PSU from darky.

Fitted it to my PC and started it.

The PC booted properly. I was so happy.

I shut down the PC, closed the cabinet and restarted the PC.

Got some kinda musical tune. Shut down immediately and restarted...

got the error "CPU shut down due to thermal overheating".

Opened up the cabinet, rebooted the PC and it ran fine for couple of hours

and then it shut down all of a sudden. I was unable to guess wat caused the shut down. I thought CPU overheating maybe.

I tried to restart the PC but the PC wont start again :hap5:

The Green Power Led remains always on but the power switch doesn't work.

The Reset switch doesn't work as well.

What do I do now? :huh: Help Me plz!!

Mobo: Intel 865GBF

CPU: P4 2.8E

SMPS: PowerSafe 400W
 
Just check if the power and reset cables are fitted correctly on the mobo, otherwise short the same with the help of a screw driver.
 
I have checked all that man...

the thing that amazes me is green LED is always on even before I press the power button. After I press the power button, nothing happens, fan doesn't rotate, pc don start, nothing... :(

It was alright b4 the PC crashed unexpectedly...so it cant be a power button fault.
 
Which green LED are you talking abt exactly?? Most of the time the green LED on the mobo is always on when a power source is connected. That does not always indicate that the PC is switched on....
 
The green LED is on the mobo, it indicates that the mobo is getting the powersupply, but you will yet need to switch on the PC through shorting the same. Refer to your mobo manual for checking the power pins and then short two of them with the help of screw drivers.
 
well..i am talking abt the green LED on cabinet not on the mobo...

afaik, the green (power) led on cabinet turns on only when u press the power switch

which it used to do befor this problem occured but now the power led is ON

even before I press the power switch. Even after pressing the power switch, nothing happens.
 
EXACTLY the same thing happened to me on 2 occasions -
1.when PSU blew up
2.when HDD blew up :P

check these two:cool2:
 
the PSU is new and the HDD is almost new :P

I've checked the HDD on friend's PC..its fine.

dunno abt PSU. :S
 
If the "some kinda musical tune" you mentioned was like the sound of British Police Car sirens then that it an indication of a problem with the CPU.
 
Take the motherborad out of the cabinet and test it. Maybe, just may be, when putting your new ps, you have inadvertently moved something which is causing a short. Also try minimal configs to see whether it is posting (1 stk Ram, no hdd etc).
 
Make sure that therez nuthing wrong with the power button , i.e if its internally stuck in the " on " state . You can verify that by unpluggin the power jumper and using the screw driver to short the power pins on the mobo .

Or the RESET button .... this happened to me with my old VIP full tower cabinet.
 
eh? just remove ur RAM and install it in any other slot, same thing happend to me, turned out to be that, or ur gfx card is not installed properly, remove and reinsert.. and someone help me with my pc problem now :P
 
am at a cafe right now...will try all ur suggestions once i get back home.

n I have tested the mobo outside the cabinet after removing all addon cards,

hdd and cd/dvd drives...the same problem remains.

@Eazy: never heard a "British Police Car" siren but yeah..maybe its smthing like that. After that i got this "CPU Shut down due to thermal overheating" BIOS screen on next boot. "Press F4 to continue"...I did the same. The PC started properly and ran fine for 2 hrs or so before it shut down again all of a sudden :(

the sad story continues :cry:

this is wat i did today...

cleaned all dust and dirt frm on and arnd my mobo...

reasembled my PC and powered it on...the problem still exists..

the green led on mobo goes on when i switch on the power supply.

the green led on cabinet goes on too...but nthing happens when

i press the power switch. the fans doesn't rotate...nthing at all.

i have tried shorting the power switch pins with screw driver as

suggested. it dint help...even tried removing and reinserting the

battery, dint help either.

wat to do next? i am clueless... :(
 
This may sound stupid.....

But did you remove the CPU from it's socket recently?? Coz if so, maybe one of the CPU pins got bent. It happened to me once and the PC never booted. Or maybe the Heatsink is not making proper contact with the CPU....
 
I too feel the heatsink and cpu contact might not be well causing overheating.
also when u removed the cpu did u reapply thermal paste.
 
firstly, i have re-assembled the PC yesterday...so, i can assure you that CPU pins are alright. I have reapplied thermal paste and all but its not the case of CPU overheating anymore.

my PC is just not booting. When I power ON the PC, I see the green LED on mobo ON and the green LED on cabinet ON. I press the power switch, nothing happens. Is it a mobo problem? or smthing else?

I dont think any Green LED on cabinet is supposed to come on when the wall socket power is switched ON - only the one on the MoBo is supposed to be on at this time - the cabinet LED should only come on after the power is switched on by pressing the power button on cabinet.
