| 539709 | 2007-04-10 09:11:00 | The fact that it works normally "the second time" still inclines me to suspect that backup cell. :D | Graham L (2) | ||
| 539710 | 2007-04-10 09:15:00 | I haven't tried starting up with my mouse and keyboard unplugged but if you really insist I will try it later on. The reason for this is that the computer restarts normally if you've been using it for a long time (you can think of it as being warmed up).Now that we have that missing bit of information, I wouldn't bother with the keyboard/mouse suggestion now. | Jen (38) | ||
| 539711 | 2007-04-10 09:24:00 | But Graham, Michael does say that nothing shows on the screen, when starting from cold, for 40 mins, and is getting no video feed to his monitor either; I would say possibly is a temperature-related fault in either/both powersupply or video card :2cents: | feersumendjinn (64) | ||
| 539712 | 2007-04-10 09:29:00 | Oh dear.:( Getting extra information after diagnosis does make a difference. ;) Back to basics. Unplug the power cord from the power supply and plug it back in. :) (That is a serious suggestion). |

| 539713 | 2007-04-10 11:05:00 | If it's a temperature-related fault with the power supply/video card, does that mean that I should go purchase a new power supply and video card? I don't have a PCI video card - mine is integrated into the motherboard - I'm gonna have to rip my video card off the motherboard and re-solder the new one. >_< Does the computer require a certain temperature before starting up? But then that would mean that computers would have to heat up quite fast when starting up. And nope, unplugging the power cord from the power supply doesn't seem to fix it. |

Err no, if the mobo has an AGP or PCI slot u can buy an AGP / PCI videocard. You could try ripping the onboard adapter out, good luck trying to put something in its place. (No dont do that)! Does the computer require a certain temperature before starting up? But then that would mean that computers would have to heat up quite fast when starting up. Umm nope, just as long as everything is working and connected properly, it'll boot. If it gets too high (the temp), you'll know, it'll shut off like 5-10 secs after u turn it on. |

| 539715 | 2007-04-11 00:07:00 | Could it really be the video card that's the problem? Isn't it correct that if the computer has not booted up yet, there will be no input to the monitor so the screen should be black? If the computer doesn't require a certain temperature to boot up, then how can there be a temperature fault related problem? (Just wanna confirm everything before I go and start spending money) |

Isn't it correct that if the computer has not booted up yet, there will be no input to the monitor so the screen should be black? The first thing that should happen when you switch the computer on (immediately) is the monitor should recieve a video signal from the integrated video chip as it self-tests and it should display a screen image to that effect (e.g. telling you what chipset it is (Nvidia/ATI/S3/Via/Intel etc), how much ram etc) , it should then go to the next screen where it will show the Bios version, and usually the motherboard type, does a ram test and then detects your floppy drive, hard drive/s and cd drives and then will boot from the boot drive (which can be changed in your Bios settings), normally this is the hard drive (holding your operating system (XP or whatever)). Then you will see another screen showing all your hardware, then you start booting into the Windows operating system. This should all happen within 1 minute or so, of switching on. The fact that your screen is staying black (no video feed apparently) may indicate no power is being supplied to the computer motherboard (and/or video chip), until the power supply unit has warmed up (which it does not need to do), it must work immediately; if it does not, it is defective. Thats what I meant by temperature-related. Do you have any lights, or fans running, at any point after switching on when cold? (Sorry if I offend you but I dont know if you should delve into your computer, if you are that unsure of the processes it goes thru, may be best if you take it into a repair shop, needs to be tested professionaly, probably save you money in the long run). (P.S. Could also be a motherboard problem, corroded connections, dry solder joints, bad ram, you name it, could be anything especially as you say it restarts randomly:waughh: ; possibly time to upgrade? :thumbs: )). |

| 539717 | 2007-04-12 06:14:00 | I don't want to start spending just yet. I wanna find out what the problem is and then consider whether it would be cheaper to replace the component or buy a new computer. Yes, the lights are on and the fans are running when starting the computer from cold. Does this still signify that that power supply is faulty? Any advice would be appreciated. Thankyou, Michael |
