Solved My PC is not starting up. Possible reasons..?

January 14, 2013 at 07:13:23
Specs: Win 7 32, 4

From yesterday morning, my PC is not working. It all started after I did a full night download. In the morning the fans are running an green light is on but the there was no display output. No response at all. I couldnt even shut down using the power button.

Then after that when I tried to start PC, it boot up to the loading screen, then to the no response state (NRS) with fans running.

Sometime it get as far as desktop and then goes to the NRS state.

By each start the condition get worsened, and now its only NRS state and some times I can get to bios.

Now the trouble shooting steps I have done.

First I checked if that was a software issue by trying to boot into a live cd of puppy linux. No success

then removed all external cards. had a graphic card and a PCI usb 2.0 4 port card. removed the case fans. -- no succes

then removed all hardisks.. and tried to boot into livecd no success

removed cd drive and tried to get into BIOS. some times it gets to BIOS, but mostly to NRS state.

swapped with another ram module.. no success

removed all external connections except vga -- mostly NRS state

Now

I am almost sure that my mobo is the cause of this issue..

And I will be buying a new cheap PSU tomorrow., will that give any hope.

What is your opinion, what may be the issue?

List the system specs first.
Don't buy cheap PSU just borrow one for testing.
Also examine the motherboard for bad caps.

Agreed, don't buy a cheap PSU. Did you check the CPU temp?

Its a pentium 4HT 3.06ghz, asus p5gd2 mobo, 2gb ram, hd6450 gpu, sata hdd 3x80gb, and pata drive. A 350w psu (its an old one).

I cannot check temp in bios, and i cannot startup an os to check temp using any software.

I just bought a PSU, and its now working fine. The PC just start up just like normal.

One doubt any way.

The new PSU have a v 2.0 out. the boards supports it. but older PSU had a v 1.0 out, which was connected to the board with only 20 pins.

Now I connected all 24 pins. will this cause any issue?
