Computer freezes, no error sounds or messages

[bejamartins]

Hey guys, I'm not sure whats going on, but I suspect it's the HDD or RAM prime suspect is the graphics card,

The symptoms are a complete freeze at random times, the image stays still, unresponsible to both mouse and keyboard. It may happen at windows loading, inside the desktop or in any other activity. No error sounds nor bluescreen nor error message.

 

The specs are:
- Motherboard Gigabyte G41M-Combo Rev 2, latest BIOS;
- Intel Core 2 Duo, just upgraded form a Pentium 4, the problem existed before the upgrade and still lasts;
- ATI Radeon 4650 HD, I believe;

- IDE HDD;
- 2 GB/Ram (1 dimm) (it used to have a second 1GB one, but recently died).

 

What do you guys think it may be?

 

Edit 1: Managed to run Windows Memory Diagnostics Tool and no problem found.

 

Edit 2: Tried another HDD, same happened.

 

Edit 3: Applied some pressure on the graphics card against the mobo and seemed to have improved the situation (but not fixed it).

Does it stop responding until you restart or just for a few seconds?

Until I restart.

Naughty computer! A lot is expected from a well behaved system.

I think 'Unresponsive' is the word you want.

Is the HDD activity light flashing? Maybe you are not leaving enough time before re-starting

I don't have any media to burn or write it on, but I'll go out and buy a CD later.

Meanwhile tried CHCKDSK from Windows Recovery and said there were problems with the disk, runned with /f, it said it fixed it but could not write log with return error 50.

I also tried an other samaller HDD, SATA, I had laying around with Windows 7, same different thing happened, mouse and keyboard stopped working but after unplug and plug got them working. Nop, it did the same.

 

Could it be the graphics card?

@bejmartins It could be a problem with the graphics card. maybe you should disconnect it and use your motherboards connections instead and see if it keeps freezing

Yup, just done that, no freeze so far. Graphics card it seems.
