Intermittent BIOS Problems

September 25, 2009 at 21:41:13
Specs: Windows 7
I installed a new wireless pci card today, and ever since, the computer frequently fails to boot. I had to clear the BIOS with the pin to get reboot, even then it only sometimes boots (1 in 6 tries or so). Computer will beep, then sit at blank screen. Screens are getting signal, as light turns from yellow to green indicating recieving a signal. No HDD activity, no BIOS screen. If I do manage to boot, however, the OS is rock solid. Intel burn test with no errors. This one really baffles me, any ideas?

By the way, of course that card is no longer in my system.

Try re-seating the RAM and the video card (if there is one). Is the box full of dust?

Power supply is a 500W Silverstone, I have checked power consumption, it has never been over 300W. I keep the case clean. I also tried reseating everything in the case. Thanks for your help, I seem to have solved the problem by reloading then resetting the BIOS. I am guessing either there was an error in the BIOS or a setting was conflicting with the card. Has not stopped since the reset/re-flash, and the card is installed.
