| 425719 | 2006-02-02 02:42:00 | I think I read somewhere a couple of months ago that there was a dud batch of TT 420W PSU's. Check it anyway | Myth (110) | ||
| 425720 | 2006-02-02 05:18:00 | I dont have another power supply with the 4-pin 12V connecter. i turned on the computer with no heatsink/fan on the CPU, and it was dissipating heat - does that mean the CPU is fine? or do dead/fried CPU's still dissipate heat? | stephen (9719) | ||
| 425721 | 2006-02-02 06:18:00 | It is not something silly like the "reset" button jammed on, have you unplugged it? I think it is one of a first step things to try when there is no POST routine, (and it is so cheap to test) we don't want to get hit by "target" again. |

| 425722 | 2006-02-02 09:11:00 | lol, nah the reset switch isn't stuck. i had pulled that plug out of the motherboard. good thought tho!! i hope it isnt something silly like that tho... | stephen (9719) | ||
| 425723 | 2006-02-02 10:40:00 | As per Graham's reply, I think your something is on/to do with the mother board. Why would it not POST if the PSU can can power a fan, it takes 5/8ths of F-all to power a POST beep. if you were getting power and a signal to the CPU and the CPU wans't behaving, you'd get a POST beep. Can you access the BIOS, I guess not, if it's not POSTing, but...! maybe short it and see what happens as a last option. |

| 425724 | 2006-02-03 05:28:00 | 'short it'? how do i go about doing this murray? | stephen (9719) | ||
| 425725 | 2006-02-03 08:43:00 | Some boards have a jumber near the CMOS chip which contains the BIOS, which you set to connect the contacts or you can flick the battery out. The object is to reset the BIOS to the factory defaults by disconnecting it from the battery, if something has screwed it up or reload a backed up BIOS if your board supports this feature. (NB. Not sure why it is called shorting, someone like to explain?) The method will depend on your board and I hesitate to lead you down that track because a) I'm not that certain of the method having done iot only once a long while back. b) Fiddling around with your BIOS should always be a last resort, it can go wrong leaving you, effectively, with a dead board (hmmm) c) I'm not sure whether I'm talking a complete load of pooh so, would like to get some backup or get dissed by one of the other members for suggesting such a ludicrous thing. Or I could just give you a link: TroubleShooting The Motherboard (www.pcguide.com) or Two -Jumpers (www.pcguide.com) |

| 425726 | 2006-02-03 11:54:00 | That's a pretty safe thing to try in my experience (resetting the bios with the jumper). Just don't power it up with the jumper on. Even very dead CPUs dissipate heat, so unfortunately that doesn't mean anything. Leave the jumper in the clearing position for about 15 mins with the power unplugged (most likely unnecessary but you need to in some). Otherwise just try replacing 1) motherboard 2) CPU 3) PSU (thats in order of likelyness) until you find the fault. I think this one's gonna cost :(. |

| 425727 | 2006-02-05 23:23:00 | Oh, yes i had actually tried that in one of the few things that i thought that may help. Im just going to have to ring up Intel and get another CPU, as its still under its 3 year warranty, and be prepared to buy another motherboard, if the CPU isn't the problem. Thanks for the help guys, il let ya kno wot it is that fixes is when i get it done! :cool: | stephen (9719) | ||
| 425728 | 2006-02-09 02:35:00 | Took it in to a shop in town, they did a few tests and confirmed the CPU was working correctly, it in fact was the motherboard some IRQ failure. So its off lookin for a new motherboard... | stephen (9719) | ||
