It could be that your processor has been overheated too many times and has failed but it could also be that the heat sink compound between the processor and the heat sink needs replacing. Try that first as it is a cheap fix if it works.
I have a 2 yrs old, home built system with the following:
- OS: Windows 7 premium edition, 64 bit
- Processor: AMD 2.10 gigahertz, Phenom 8400, x3 core
- Hard drive: 200 gigabytes
- Motherboard: ECS GF8100VM-M5
- Memory: 2MB + 1 MB
- Display: Nvidia GeForce 8100 / nForce 720a
The pc was built by someone else, so I don't know much about it. It worked fine until a few weeks ago when it started switching off without any error messages or warnings - just as if someone pulled the plug (and I haven't). I would just turn it back on again. It only did this while gaming. It also started to lag. I ran anti-virus, but it found nothing. Defragmenting the drive helped it run slightly faster, but it still wasn't its old self.
Then, a few days ago it switched off and would not turn on again. Only the fan lights blinked and nothing else.
I thought it had something to do with power supply and bought a new box.
It didn't help and it only turned the fans on for a moment, just like the old one. So, I put the old one back in and looked up the forums.
I plugged in one cable at the time and found that everything works until the ATX 12v connector cable is plugged in. As I understand, this connects the CPU.
I also read somewhere that the motherboard is supposed to beep when powered. I am not sure if my one ever did this, but it makes no sound now.
- Does this mean that it needs a new CPU?
- Motherboard has a fan that is powered through it and it works. Is it possible that the motherboard is still faulty in some other way that allows the fan to work?
- Maybe it needs both, motherboard and CPU?
Any help to solving this is much appreciated.
