Power on self test windows 106/12/2023 ![]() ![]() Each card’s metal bracket should be secured to the chassis with a single, snug screw. Every card should be inserted evenly and completely into its slot. Check all the expansion boards, especially the AGP video card. Fortunately, a few quick checks can reveal the most common problems. ![]() You can see the beep codes for a few popular BIOS makers listed at PC Hell ( ) and Computer Hope ( You can usually narrow down most beep problems to three key areas: memory, video, and motherboard. Beep codes can vary a lot between BIOS makers. When the system discovers errors, it attempts to report the problem as a code or message. ![]() PCs perform self tests each time you apply power. In fact, the blank monitor indicates a very serious problem early on in the self-test startup routine. In fact, set any unused drive spots to None (rather than Auto) to prevent the system from checking for nonexistent drives. If it lists other drives first (like a floppy drive or CD drive), the BIOS will waste precious seconds waiting for each drive to respond. Make sure the boot sequence lists the drive you boot from most frequently first (normally the C: drive). Also, check the Boot Sequence, which lets you specify which drives the BIOS checks for bootable media (in other words, an operating system). This prevents the system from looking for a floppy drive at each startup (a test that can take several seconds). You can also disable the Boot Up Floppy Seek option. When enabled, the BIOS skips optional parts of the Power On Self Test (POST), such as the memory check. For example, the Phoenix/Award BIOS version used with the Tyan Tomcat i7210 (S5112) Pentium 4 “Northwood” or “Prescott” motherboard provides a Quick Power On Self Test option in the Advanced BIOS Features menu (see Figure 1-6). Most PCs make it through the self-test part of each startup in less than 15 seconds, but you can change several default BIOS settings to shave a few precious seconds off the normal startup. ![]()
