HELP!! Running into issues left and right!!

[killalldude]

:cry: Ok, so I built this new computer a few weeks ago, and it was working just great. Some days ago, I was just surfing the net and my computer randomly turned off. I tried to on it again and the fans spun for a couple of seconds and then just stopped. I googled around and concluded that my PSU went bad. After installing my new PSU, I booted up my system again and there was a loud POP sound. There was no display on the monitor at all. I shut down the computer and smelled all of the parts. My graphics card smelled like a used firecracker so I decided that my card went bad. I had another crappy card lying around and plugged it in. When I booted my computer again, everything seemed fine, except there was still no display on my screen. All of the fans are spinning and everything. Even the GPU fan was spinning. I googled around again and have so far learned that my motherboard may have gone bad. I really hope that this is not the case. Any help would be appreciated. :cry:

 

My specs:

 

Motherboard: ASRock SuperComputer

CPU: Intel i7

Graphics card that smells bad: nVidia 9800GT

Crappy Graphics card: nVidia GeForce 8400 GS 512MB

Power Supply: RAIDMAX RX-730SS (730 watts)

 

Tell me if I left something out, I probably did.

 

Also, with my old power supply (700w COOLMAX CUG-700B), the computer did not turn on at all. The fans spun a couple times, but nothing else. With my new power supply, the computer actually turns on, but there is nothing displayed on my monitor. I have not overclocked any part in my computer.

Did you apply enough thermal paste to your processor?

Can the PC boot into the BIOS (IE, can you hear a short beep even if there is no display)

is your VGA/HDI cable working properly

Same for your monitor, does that work?

 

There are many things which spring to mind when a PC just shuts down and doesn't come back on.

1: Processor. Could have burnt out (hence the thermal paste)

2: Motherboard. Could be kaputt, the fans turn on as a diagnosis.

3: Graphics card. IIRC, PC's can't boot properly without a display device.

4: Power fault. Maybe the house's power cuts out with your PC (some houses do!)

 

They're the only things that spring to mind at the moment, but if you could give a little more information on what happens, as in the fans spinning for a certain time/indefinately. etc.

^ Thanks for the help Mr. Spongie =). Now my computer is running fine, except my graphics card fan (9800GT) isn't spinning. Is it a DIY type of repair or should I get the card repaired? When I manually spin the fan with my fingers the fan does not rotate smoothly and there is a scratchy kind of sound.

if a mod comes by this thread please delete it, issue resolved.

Neh, no deletes. :lol: Some may have the same problem as you and wish to know how you resolved your problem.

 

if your GPU fan stops spinning... it usually means curtains for it, unless it's watercooled.
