| 772170 | 2009-05-08 05:49:00 | I recently made a thread about a problem I was having where sometimes my BIOS would not recognise my video card, and this could be temporarily fixed by switching the PC off for ten minutes. I now have a new issue. When I try to wake my PC from sleep it powers up, but the BIOS does not start, as though the CPU is not going. Flicking the PSU off and on again fixes it. I think this sounds like a PSU problem. Perhaps the power supply is degrading with each use due to being overloaded? | sammo450 (13626) | ||

What are you seeing that tells you it can still power up eg, fans spinning, DVD/CD drive can be opened. Do you mean the BIOS is not starting up because the monitor remains blank, or something else? Does this problem only happen when the computer hibernates/sleeps? |

| 772173 | 2009-05-11 00:42:00 | Which wires are those? @Jen: yes that is pretty much it. I think it only happens if it hasn't had much of a rest after it was put to sleep. | sammo450 (13626) | ||
