PC just keeps on rebooting but if it does start up, it only lasts for maybe 5 or 10 minutes and then goes blank (black screen). It now powers up when I switch it on at the powerpoint, don't have to use the on/off switch. Don't know if the two are related, but would be glad of any advice. Running WinXP Pro with 1.6g processor and 1g ram. No joy with new power lead. Many thanks.
Thanks CF, I removed the heatsink and there was a bit of dust there. I had already cleaned the fan. When I turned the PC on, it looked promising, but after about 10 minutes it went blank. One thing I did notice was that the fan on the graphics card wasn't working - could that have anything to do with it? Liz
Thanks rojash, just making sure that everyone is wide awake. On my way to get new card. Strange that a so-called whiz-kid never noticed when he had a look at it. Liz
