Booting up problems - Abit IP35 Pro

[unclebob123]

Hi guys,

I'm having problems booting my PC up, and I've never had this happen to me before so I'm a little clueless. I turn the pc on, and normally the fan starts at full speed, then slows right down and booting commences. Now however when I turn the PC on the fan stays at full speed for a few seconds, then the pc resets and fan continues to be stuck on full speed. All the time there is nothing on the monitor.

Looking at the 'error console"(?) readout on the mother board I have two codes. When the PC is off the readout says 9.9, and when it's turned on it says 9.0

Looking on the Abit website the error message says this is the cause

Award BIOS initial stop processing1. OC too high2.BIOS dead

and this is the solution

1. Clear CMOS2.Restore default setting for BIOS3. Replace BIOS chip4. Send to RMA at last

Just to note I have not changed any settings or installed anything since this problem began.

Any ideas

Thanks

Ok a quick update. I have tried clearing the CMOS firstly by using the clear CMOS switch on my motherboard which didn't work and by removing the battery for a couple of hours which also hasn't resolved the issue.

Any other ideas?

On my IP35 after a CMOS reset, I have to increase the default memory voltage from 1.8 to 2.1. (check with your memory manufacturers guidelines for default voltage). If, with more than 1 memory slot occupied; I don't do that it doesn't have enough juice and will not boot.

Try unplugging everything from the board and brushing it off then hooking it back up again, this includes the back panel cables too.

Might be your video card too.

I had a similar problem. I could get it to boot sometimes, especially when disconnecting all drives but one, and after clearing CMOS. It wouldn't stay on for long. When it shutdown, it was 9.9.

Short answer was it was my PSU. I bought a new one yesterday, put it in, and have no issues.

Yay!

Long story -

1. Thought it was a bad hard disk, my boot disk kept getting corrupted. Swapped boot disk to a new SSD drive, still had problems.

2. Thought it was my ram, reseated, tried using one (or the other) stick instead of two. No dice.

3. Thought perhaps corruption in bios, reset cmos. No dice.

4. Thought it was ram voltage issue, raised voltage to 2.1, no dice.

5. While i was checking ram voltages, I saw my 12 v looked a bit on the low side. See screen shot BEFORE.

6. I had a brand new spare PSU, but it didn't have the 8pin 12v. Picked up a new PSU and plugged it it. See screen shot AFTER.

Ran overnight, with CPU and GPU at 100% and no issues. I consider this fixed.

Good Luck!
