Anyone know anything about computers?

[Hightower]

Pc's been playing up for a while. Everythings OK when I boot up initially. After entering a user account my pc sometimes:

1. Crashes and freezes.

2. Monitor switches it's self off and on several times, then pc re-boots

3. Everything slows down and takes an age to get going.

This all started happening about a month ago and has been gradually getting more frequent.

Sometimes when I do get her going I get a report saying that there's a Nvidia Driver problem! Or other messages referring to the Graphics! All the newest drivers have been installed/uninstalled with no affect .

Thing is once I get over the boot process and logging onto my account, she runs fine till the next time I start up.

I'm gonna open up the case this weekend to have a poke around as a fan is making some pretty weird noises at the mo and everything needs a good dust off and clean up.

Any Idea's or suggestions on things I could do before I reload all the software and start again?

I've had a problem in the past with the processor overheating when the cooling fan was kaput, it started doing things a bit like yours.

Otherwise it may just be a "Windows is tired and emotional please back up anything important and reinstall the whole #kin thing from scratch" error

Mine was doing exactly what Hightower's is doing. It sorted itself out after I ran checkdisk at startup and told it to do a full drive scan.

Andy we also had problem like this, with the monitor closing down it was my graphic card overheating this was due to the machine being pushed back to close to the wall when the kids were playing. Hope you get it sorted.

Had the similar problems on mine and it was due to the graphics card overheating due to the cooling fan not working,check it out before it cooks itself .

Try making one change at a time and see what happens. I'd boot up in safe mode first and if it still does it then you know it's not a driver problem which would then point to as the previous threads stated a hardware malfunction.

Bios says temp processor temp is 32c and case temp of 38c

This is a problem only at startup and once I get running it seems to stabilize, so I dought it's a temp problem.

I'll reload all the software first and see what happens

I also read somewhere that the Bios could be outdated and a windows update could be uncompatable with this.....Anyone care to suggest if this could be true?

Andy,

Is this a new graphics card and which one is it. Also what motherboard do you have ?

I've just fried a Nvidia 7800 GTX and my last computer was pretty awful on the graphics side with loads of crashes and that was a bang up to date Nvidia card as well.

It does sound likely to be the graphics card.

The funny noises from the fan - are they still going when its working fine?

The bearings may be shot in the fan on the graphics card.

I'd first try safe mode, and then if it still fails in there try changing the graphics card.

I haven't a clue what the bits and peices are inside a computer. All I can say is that it's a couple of years old and has been working fine up untill these problems started.

I've backed up all my files but can't find my server conection discs, but when I do I'll reload all the original software and see what happens. The wait for days whilst the Microsoft Windows updates get installed.
