PC doesn't get passed POST, fans working, no beeps

Hello, I'm having a bit of a problem here, hope you can help me find what part of the computer is behind this.

For the past month, I've seen my computer restart on its own spontaneously about once or twice a week. Then yesterday I got home to a computer with a frozen window, mouse and keyboard not responding at all so I restarted but the computer would not start, the fans were working but no beeps and no monitor response.

Tried reseating the RAM and unplugging everything but the motherboard but still nothing, so I'm thinking it's either the motherboard or the PSU, but I really can't be sure and I can't really afford to buy both of those things in order to find out who the culprit is. So any help would be much appreciated.

Here are my computer specs or at least, those I couldn't find out :

ACER Aspire M5640-E5511A

- couldn't find the motherboard model/brand name
CPU : intel Core 2 Quad Q6600
RAM : 4GB DDRII
Video : integrated graphics
PSU : no idea.

Thank you,
Francis.

Hi

Have you checked the cpu pin connectors are seated correctly? Disconnect the hard drives and then see if you get POST!

I would go for a faulty PSU in the first instance plus its cheaper than motherboard. If you look at your motherboard at the capicators, look for domeing at the top or leaks

Thanks you all.

Turns out it was the motherboard that fried, I changed it for an ASUS P5KPL-AM SE, and except for the front panel connections, everything went smoothly.

But since this new motherboard's been up and running the fans have been working crazy making them far from silent, does that mean any problem of some sort ?

Thanks,
Francis.

Maybe EIST , Enhanced Intel Speedstep Technology, is not enabled in power options, these sites may explain how to check for and enable EIST, so that the processor is not running at full speed when idle
