QUESTION My 18-month-old laptop reports the following error message at startup: ‘Broadcom base code PXE-E61: media test failure, check cable PXE-MOF: exiting Broadcom PXE.ROM. Operating system not found’. I can get into the Bios by pressing F2, but I don’t know what to do from there. Graham Shorter

HELPROOM ANSWER It looks as though your hard drive may have failed. It’s also possible that the Windows boot partition may have become corrupted. Run the Windows recovery disc supplied with the PC and use the options offered. Do not reinstall Windows – you’ll lose your data.

If you still can’t boot into Windows, enter the Bios and check that the boot order gives priority to the hard drive, followed by the CD/DVD drive. Then try removing and reconnecting the SATA cable that connects your hard drive to the motherboard (see your laptop’s manual for instructions).

If this fails, call Acer and have it fix your laptop under warranty. If you no longer have a valid warranty, you’ll need to buy and install a new hard drive, then reinstall Windows on it. Use a drive caddy to try to recover any data from the old drive.
