Booting Issues

Hello,

I've a Lenovo all in one desktop running W7 64 HP. Trouble is sometimes it starts fine, other times it just lights up and the fans run but nothing else - no BIOS output on screen or anything.

Does anyone have any suggestions as to where the fault might lie?

Thank you for any pointers, getting a little frustrated by this problem now

Could be a difficult one to diagnose without swapping in/out spares. Could be a dodgy memory chip, could be graphics card, could be processor, could be PSU, etc, etc. Could even be a dodgy monitor.

Does it emit any bleeps on boot up? Normally if there is something seriously wrong then it will emit a series of bleeps (unless of course HP are too cheap to include an internal speaker on their all-in-ones).

Hello and thank you very much for your kind reply,

Have tried swapping RAM, no graphics card I can see (it has inbuilt and not swappable) - processor or PSU, well, not sure what I can do to check these?

No bleeps at all when it fails to start, and none on successful start either so guessing no speaker there.

I guess I'm probably at the stage of more or less scrapping this thing which is a shame, it's only two years old...

Will be difficult to track down without any indicators of what is failing. Your only other option would be if you have a local IT place that might be able to do some swap out testing using spare parts. If they do it for a reasonable price it might be worth it (depending on how much the PC was in the first place).

I know that Novatech provide a service like this and have a few stores around the country. Personally I wouldn't go to PCWorld but that is an option.

Take it back to the supplier of the machine as it is their responsibility to supply goods that are of merchantable quality. You have up to 6 years (5 in Scotland) to get the PC fixed or exchanged by the supplier.

Don't be fobbed off by "it's out of warranty". Sale of Goods Act 1982 covers such issues.

Disconnect all external devices (everything except the monitor) and check that the monitor cable is securely connected. Some systems will not POST if they cannot detect a monitor. Also, check that everything is seated properly--memory, daughter-boards and internal connectors. Another (rare) fault that had me tearing my hair out on one occasion was a faulty sensor on a CPU fan. The fan was spinning but the system thought otherwise.

Seconded.

Agreed take it back to the supplier, you have 6 years in England.
