| 781946 | 2009-06-13 06:38:00 | At what point does it reboot? Can you tap F8 then select "Disable Automatic Restart" it may be a BSOD. Have you tried safe mode and last known config? Blam |

| 781948 | 2009-06-13 06:49:00 | Could be overheating, ensure that all fans are working and that the fans and ducts are clean of dust/dirt. | stormdragon (6013) | ||
| 781949 | 2009-06-13 06:53:00 | See if you can hit F1 and access the BIOS. Its most probably overheating, open the up the side of the case and make sure the heatsink has no dust clogging it and is on tightly. Blam |

| 781950 | 2009-06-13 06:54:00 | yer did check there was a bit of dust on ducts but now clean , fan starts up with PC then dies . Its cool now as ive had power cord out for 10minutes and still does the same powering on and off | dgoddard (8993) | ||
| 781951 | 2009-06-13 06:56:00 | Don't forget to check the heatsinks as well. Try disconnecting the power to the hard drive, cd drive, (floppy?) and see if it will stay alive. |

| 781952 | 2009-06-13 07:00:00 | ok help what does a heatsink look like? | dgoddard (8993) | ||
| 781953 | 2009-06-13 07:00:00 | In that case I would try another PSU. Sounds like its about to die. Heatsink it a big thing sticking out the motherboard with a fan on it Blam |
