Any thoughts / solutions? - any known problems with these PCs?\n\nFolk's HP Pavillion (slimline S5206UK-P-E6300) - about 18mths old. Usually faultless. Now the link on their router flashes\nquickly - about 5Hz. Any port (of 4), other computer on same router okay. Cables swapped (same), cables tested (okay).\n\nFlashes as soon as pc powered up - doesn't wait for windows. General internet difficulties. Does get an ip (dhcp) but expect\nnetwork not really working.\n\nIf on-board lan disabled in bios, then flashing stops. Otherwise, flashing (inc. safe modes).\n\nWin7 home premium (not too familar with w7 - windows not reporting any network issues).\n\n- I'd have sub'd a gash lan card but only pci (express?) with short height end panels and two tiny edge (what are these called?)\nconnectors in there.
