Right, this could be a long post.

A few weeks ago my mums computer (P4 3ghz, 512MB RAM) started making a strange noise. It sounded a little like a hard writing type noise but louder and a bit more squeally.

We wondered if it might be a problem with one of the fans. But wierdly, while it was fairly constant, it also seemed to occurr at various times when working on the computer, for example scrolling through a list of files in Windows Explorer.

We thought it might be the hard drive dying.

After a couple of weeks, the computer started crashing, at first it was occassional but has gotten worse and worse to a point whereby it can take several (6 or more) attempts to get it into Windows and not have it crash immediately. By crash I don't mean it blue screen or anything like that, it just literally dies and reboots.

Each time it tries to boot, it does a disk check and has thrown up errors about the pagefile.sys being corrupt or truncated etc.

My guess was that the hard disk was dying.

I purchased a new HDD and, having managed to backup everything from the old disk, decided the easiest option would be to bung the new drive in and start a fresh install of windows. I started to do this and formatted the drive to NTFS and started to install windows and it crashed again much to my surprise.

I'm now wondering if it might be a problem with the power supply?

I do somewhere have a spare powersupply which I intend to try this weekend.

If the different power supply doesn't solve the problem I really am stumped as to what the problem moght be?

I have tried disconnecting the CD drive but it stiull crashed.

I have tried running Knoppix from CD and it seemed to be working much better, it booted first time and stayed working for about 20 minutes before crashing again.

I would have disconnected any pci cards but there aren't any, it's onboard sound and network and nothing else so I don't know what else I can check really.

I am going to run memtest to see if the memory is ok, after that and trying the different power supply I am out of knowledge...

Does anyone have any thoughts about what the problem might be if it's not the memory or the power supply?

Any help very veyr much appreciated.
 
the noise could be from the mobo as well, check none of the capicitors are starting to swell up, I also saw a video card (nvidia) where the capicitors had blown...(i dont know what the correct term is but the look like the top is swelling up and about to pop) - the tops should look flat... -if the noise is there all the time you can try and take the gfx card out and power it up to see if the noise stops (only proves anything if this does NOT stop the noise)... then you knows its gotta be the mobo (I dont think the cpu or memory can make the noise - might been to get someone to confirm this)
 
Issues seem to realte to windows graphical activty or driver loading

If that pc has an add in graphics card then I would check if its fan is clean, rotating freely and if it needs any extra power lead (unlikley) that its fully attached.

Consider whipping it out, cleaning it up and reinserting.

Fans (psu, cpu cooler and graphics ), graphic cards and mobo voltage components are all potential sources of 'odd' noises
 
Tried unplugging the case fan, the strange noise was still there.

pushed lightly on CPU fan to slow it down but didn't make any difference to the strange noise so I think it's not that.

PSU has two fans both of which are spinning but I can't get to them at all to try stalling them to see if it makes any difference to the noise.

Has onboard graphics as well as audio and network, so no cards to take out and try without.

Will check for problems with capacitors too.

Would be very surprised if it was dust related, it's the cleanest inside of a PC I have ever ever seen.
