Why Can I Only Boot To Bios?

carts60 · 27 Feb 2015 at 08:59

Hi guys,

So this is a fresh build.

Works perfectly but at the end of each session, the BIOS seems to wipe and I always have to boot up via the BIOS.

I have checked the CMOS, updated the MOBO and done everything I can think of doing.

Do you have any suggestions as to whats going on?

Much appreciated all.

Oh, and for the record, I have no idea why it thinks I have 3 mice

What motherboard are you using?

I had this once on an old, old machine where the BIOS battery died. But it didn't tell me I had 3 mice!

Its an ASUS M5A97

Is there a way to check the CMOS battery?

Hmm.
Says to me "duff battery". But also check for a jumper for BIOS resets if your board has one- I don't know if a machine will start with the reset jumper bridged, but worth a look?

Yeah, iv checked the jumper.

It won't post in the reset position

Replace the battery, as advised above.

when you do go into the BIOS does is date/time different each time?
Could well be duff battery

Do you have any beeps?

Could be a memory issue at boot, is it 1333MHz? Timings may be wrong.
Voltages for memory and/or CPU vcore. Try manual settings rather than auto for these. Vmem 1.65V
Vcore 1.45V, you can always refine this later.

good luck.

My initial reaction is CMOS battery is dead so settings don't retain at power off, its the cheapest thing to replace before you rip things out of your system. Get one from [popular online auction site] or [rainforest based online retailer] for less than a quid normally

as others have said if its clearing the cmos once the PC is off replace the mobo battery

If it's clearing the BIOS every time, it suggests the battery. It's inexpensive to replace and worth a try before doing anything else.

As an aside, the old machine I mentioned used to first reset it's date to 1961. If we forgot to change it, we got all kinds of funny dates in the BIOS and Windows - at one point it rolled back to 1899!

OK thanks all.

Yes, date and time all reset.

I'll get a battery and replace to see what happens tonight and will report back
