Hello, i have an HP G62, i have the black screen at startup, no post can the get into bios, when i start it i hear the fans and hdd spin, but nothing but a red wifi indicator and continuous caps lock flash, doesn't stop and blinks every 3-4 seconds, i have tried taking out hdd and putting it back, tried heating it up inside a towel as suggested tried using one ram module, tried switching ram spots, tried unplugged wireless card ans starting without ram, still same thing, tried using just power cord and tried power cycling by taking battery out and holding power for 30 seconds, any help would be great tried everything i've found and no luck. Thanks a lot
