Start Up Problem etc

  harleyd 19:44 13 Sep 2007

Hi All. Wonder if you can help. Recently when starting up my PC (XP, 1g memory, about 18 mths old) I get a screen full of coloured vertical stripes, after 3 or 4 shut downs I'll get the normal log on screen and everything tends to work as normal. I've tried system restore for several different dates but it just errors (has worked on previous occasions) and I've also tried to delete some recent upgraded programmes, to see if there's a conflict (Spybot, Ad-aware etc) but I'm unable to un-install them. Anyone any ideas or is it a complete re-install of XP. HELP !!!!

Look in your Device Manager for any exclamation marks against the Graphics Card. To go to Device Manager, right click My computer and select Manage. There may be a fault with your graphics card?

Agree with recap, sounds like a problem with your graphics card. Can you run the DirectX tests OK? (start menu/run, type dxdiag, press return)

Hi recap/brundle. I've run the DirectX tests, theyre all showing ok in the Device Manager but I've got a yellow question/exclamation mark against Other Devices/Raid Controller. Does that mean anything to you?

That's to do with storage, shouldn't affect your display. Do a stress test; click here

If the problems persist and the graphics are OK generally, it could be a power supply issue - the PSU has to work hardest at boot up.

Hi again. I've done a stress test, loads of figures came up & a bench mark of 59? Does that help at all?

Suspect your PSU. If the stress test completed without issues or crashes your video card is almost certainly OK.

Hi Brundle. Sounds very naive, but where do I go from here, do I just get a straight forward one for one replacement, can I fit it myself (once I find it) etc etc

If renewing a PSU check:

1. The physical size of your PSU, some are hard to replace due to being a non standard size.
2. The amount of power need from the PSU don't skimp

1. Physical Dimensions

Besides the specs and form factors, the physical dimensions are also important factors in selecting a compatible power supply. Here is an outline of the physical dimensions of most standard power supplies:

# ATX: 6x3.5x5.5", HxWxD. Most common. Uses 4 mounting screws.
# Mini-ATX: 5x3.5x5", HxWxD. Rare size. Uses 4 mounting screws. Can be used in a regular ATX case, but often not the other way around.
# MicroATX: 5x3x4", HxWxD. Use 3 mounting screws. Not interchangeable with ATX or miniATX.
# Flex ATX: Even smaller than Micro ATX. Various sizes according to case specs; often not interchangeable.

Use the data above to determine if a particular power supply would fit your case.

The quality of a power supply can be estimated by its weight. While this is not a true scientific or thorough measurement of the power supply reliability, it is nevertheless a very simple and easy way for ordinary PC users to estimate and compare the quality of a power supply.
