Solved Unable to enter new Asus mobo BIOS

July 15, 2014 at 05:49:11
Specs: Windows XP and Windows 7
I change my motherboard Asus P5KPL SE for Asus P5KPL. I start my PC and it says "press del to run setup press tab to display bios". On my keyboard is CAPS LOCK turn on and I can not turn him off, when I press DEL or TAB, nothing will happen.

Let's see, you've tried different keyboards, cleared the cmos, disconnected hardware and removed the motherboard from the case. I'm not sure if you've verified the cpu heatsink is properly and firmly attached but other than that it sounds like a bad motherboard.

Try a different keyboard, preferrably PS/2 rather than USB.

Why did you switch motherboards? Try temporarily disconnecting the hard drive, optical drive, & any external devices (including the mouse). Just have the monitor & keyboard connected. Also, did you try resetting the BIOS?

I switch my motherboard because i had bent pin under my cpu and when i try to fix it, the pin die. I already reset BIOS. I already try it without mouse, so I will try to disconnect the rest of things and i will let you know tommorow.

Yeah, it sounds like your system is locking up. As part of that the keyboard isn't working either. Assuming you swapped the parts from the old motherboard to the new one, are you sure all the old parts are compatible with the new board?

From your description you wrecked the cpu/processor, not the motherboard. If that's correct you need a new cpu, not a new motherboard.

The socket 775 has the pins in the socket rather than the CPU.

@Krtekchuj - how did you apply the thermal paste between the CPU & heatsink? The method is different depending on whether you have a single core, dual core, or quad core CPU.

Oh-h-h for pinless cpus. I didn't even consider it was one of those.

I wrecked the part of motherboard under cpu, my cpu dont have pins. New motherboard is compatible with all my parts. I already tried disconnect hard drive and optical drive, but nothing change.

Should I flash BIOS?

To flash the bios you'd have to be able to boot from something but it appears to be locking up before it gets to the booting stage. If you can get it to boot from some drive then I suppose a bios update, done correctly, wouldn't hurt.

But I'd concentrate first on the motherboard itself. Are you sure it's a good one? Are you sure you installed it correctly? You might want to pull it out of the case and set it up on a non-conducting surface and see if it acts any different. Recheck the cpu. You just want a dab of paste on it. Make sure its heatsink assembly is firmly attached.

When you swapped out the motherboard, did you make any other hardware changes to the system?

Im unable do flash it. I cant do anything. Now i try to take out batery and I will wait till tomorrow. I found guy with same problem and he solved it like this (http://www.justanswer.com/computer/6zmjc-computer-asus-p5q-motherboard-when-turn.html). He had Asus too, so I hope it will help me. I read that sometimes you must wait couple of hours until it wil all discharge. 1 hour doesnt work. If it will not work I will try to take motherboard out from case. I dont make any hardware change.

Yeah we should have thought about clearing the cmos earlier.

Most motherboards have a 'clear cmos' jumper which does the same thing as removing the battery only it just takes a few seconds and not all day.

Locate the jumper on your motherboard. It usually consists of three pins. A jumper will be across two of them. That's the 'standby' position. With the power cord removed jumper it from the standby to the 'clear' position (the clear position will be the center pin and the pin not previously connected in standby). Leave it there for a few seconds and then jumper it back to the standby position. Then plug in the power cord and turn it on.

I've noticed on some asus boards the 'clear cmos' is just two pins. The jumper might be hanging from one of them or you may need to procure a jumper from another source. On some other asus boards 'clear cmos' was just two solder joints as if they forgot to solder the pins on. In that case you had to use a screwdriver across the two joints to make the short. Those were on older boards and I'd hope asus does things right now but you may need to consult the motherboard manual to make sure.

I tried connect the 2 jumper for clearing before, but without result... I had battery out for more than 30 hours, nothing happen. I have still the same problem.

And you had the power cord disconnected when you were doing all that? If not you wasted your time.

If it was disconnected then clearing the cmos isn't going to fix it. If possible try bench testing it by removing the motherboard from the case and only having the cpu, ram, keyboard and video attached. Make sure the ram is firmly inserted. You don't need to have the power switch from the front panel connected to start it up. Just use a screwdriver blade to touch the two pins the switch connects to on the motherboard. Then see what happens when you start it up.

Heatsink is attached properly. Do you think new CMOS battery will change something? I tried 2 different batteries, they were used but they werent empty.

It shouldn't be the cmos battery. Usually if a bios loses its settings due to a low or dead battery you'll get some message about 'bios options not set' or something similar at which time it'll say to press one key to enter bios setup or a different one to continue booting.

If you're concerned you can always put a dc voltmeter to the battery. You'll get a fairly accurate reading even under no-load conditions.
