I have a Compaq Presario 1800US laptop (2002 make). Of late, after I installed a USB wireless adapter, it has started malfunctioning. I have been getting blue screen and dump, but after a couple of days it went totally dead with a "Operating system not found" message whenever I try to boot. I am not able play much with the BIOS. Is there a BIOS upgrade available to do a hard drive self test? Any valuable suggestions would help. Thanks!
