Question for those who know about building PC's.

My dad's old XP Medion PC has been powering off (instant shutdown) whenever someone watches a long Youtube video or downloads more than a couple of files in tandem (in firefox).

I have replaced the power supply to no effect and checked for loose bits inside. While checking I found the card that connects monitor via VGA has had a small fan on the underside come loose (image in next post).

Would this be enough to cause the constant shutdowns? The PC is borderline steam powered (P4) so the little fan could of gone years ago and have nothing to do with the new problems.

Yep, processor overheating due to fan disconnected.

:lol: Its certainly not going to help!

(Yes, that probably is the cause of the problem, is the CPU fan okay?)

Scousekop - its the GPU, not CPU!

It's a teeny little fan (little bigger than a 50p) on the underside of the card that has the VGA connection rather than the PC's main fan (that works fine).

PC is a piece of junk but you know what Dad's are like when it comes to throwing stuff away. :roll:

You need to either replace the heatsink+fan on the graphics card, or it may be more economical to get a new (or second-hand) graphics card altogether. Although looking at the size of the motherboard it may also have on-board graphics (ie another graphics chip on the motherboard) - is this the case?

If you wanted a really cheap hacked-together solution and the heatsink is still attached to the graphics card okay you could try just sticking a large case fan so it blows onto the heatsink - quite how you'll attach it though I don't know!

basically the graphics card is heating up, sending a message to the mobo to switch off to protect. I would replace the gpu, but I suppose you could source a fan.

So getting a cheap graphics card would be an option?

As far as onboard graphics I have no idea, it's a very old PC so instructions and stuff have long since been lost.

EDIT:

It's an MS-7091

Does it have a 15-pin VGA connector on the motherboard back panel (in addition to the one on the graphics card)?

As far as i can tell it has just the one VGA connector on the card (and the whole PC) alongside a DVI connector.

Graphic Card: Medion Radeon X740XL

No on-board graphics then I'm afraid - here's the manual: http://217.110.237.67/Manuals/Medion%208383XL%20mit%20MS-7091.pdf

Its a PCI-E 16x slot apparently so your options are to try a cheap new or second-hand PCI-E card or to replace the heatsink+fan - it could, of course, still have other problems but the way you've described it sounds most likely. To be honest I'd probably get a cheap new graphics card as there is a possibility that the old one has been permanently damaged through overheating...

So if I was to source a cheap graphics card what steps would I need to go through to install it?

I used to (very long time ago) build my own stuff but i'm out of practice and have forgotten almost everything (damn you affordable laptops).

Anything on this site http://www.computerorbit.co.uk/ that would work as the shop is 2 minutes from me (literally). Cheap and cheerful is fine as no gaming will be done just basic web browsing and some video watching.

They have an Nvidia 7200 for £24 - you can probably find cheaper online or second-hand but its not bad for a shop-price. If you can, boot up into Windows and uninstall the graphics drivers - then shutdown (before it crashes!) and remove the old card (pretty easy to do - unscrew where it is fixed to the case [some cases are 'screwless'] and unclip the card (there is probably a plastic clip keeping it in the slot at the end of the PCI-E slot away from the back of the case that just needs unclipping) and lift the card out the slot - then put the new one in, boot into Windows and install the drivers (it should come with a CD or you can download newer drivers from the Nvidia site).

Once i've uninstalled the existing driver and i'm in the process of installing the new card I take it that some form of windows basic driver will allow me to view the desktop (only VGA will be on the card) until the new driver (for that card) is installed?

Well first I would test to see if it is the GPU overheating. Remove the broken fan from the GPU. Then unscrew the case fan and rest it on top of the GPU heat sink. Leaving the case side off (to help airflow) start the machine. If it runs ok then that will be your problem. Then just order a new fan or heat sink and fan and some thermal paste from dealextreme for a few pounds.

Exactly that - a nasty, slow, but nevertheless functional VGA driver will install itself. Worst case scenario boot into 'VGA Mode' in the Safe-Mode menu, but usually you shouldn't need to if you remove the old driver first.

As Gavin says its probably worth to try to make sure this is the cause of the problem first if you can before spending money though...

I should probably replace the card anyway with the fan the way it is as it could prove an issue regardless if it is the cause of the crashes.
