Reboot and Select Proper Boot Device

[4ction3500]

I was running stress test on the system, particularly CPU. After some time during the test, system BSODed.

I reset the BIOS to original settings and tried to boot, but got the error.

It says "NVRAM" and then it can't find the boot device.

I checked the BIOS, it detects both HDDs and I set the boot sequence properly.


I am lost here. It seems that everything is working properly, yet system can't find the boot device. Any help would be appreciated.

I have P5K-E Asus mobo. The manual says it has protection against OC gone bad, so there is no need to take out battery to clear CMOS.

Thank you,

What OS are you running?
Have you disabled the OC now?

Please provide full system specs. Thanks

Ok did you.... have it set up before you reset the bios for your drives as AHCI? By default if you reset the bios, it resets the interface to IDE. If you had installed windows and the bios was set to AHCI and then it resets and now is IDE, it wont boot and wont do anything. You must go to the section of the BIOS that has the SATA setting, set it back to AHCI and then reboot.

This might be your problem

EDIT: also the P5K-e (I have the same mobo) you have to state the boot sequence of what drive you want to boot from (you can set the order in BOOT devices. Make sure you have the correct drive first again.

I am not sure about AHCI/IDE settings I had when I installed Vista (32Bit).
I have the drive boot sequence set up to proper order. Besides, the problem with boot device started before I reset the BIOS, but right after I changed the RAM timings.
I'll try to put it to AHCI tonight and see if it helps.

And yes, system is running w/o any OC, completely stock/default settings in BIOS.


I remembered that I tried to set RAM timing to lower setting yesterday ( 4 4 4 12 instead of stock 5 5 5 15 , but I did not touch RAM voltage). Friend of mine says I might have "killed" RAM by messing up the timings. Is that possible?

My specs are:

P5K-E mobo
CPU E6750
RAM 2Gx2|CORS TWIN2X4096-8500C5D
500W Thermaltake PSU
8800GTS 512MB video
150Gb Raptor HDD as main HDD
500GB WD HDD as slave (no RAID of any kind)

Chances are even if your ram is rated for very high speeds, the timings would probably be 5-5-5--15 at that rated speed. If you check the specs you would probably find a setting that will do 4-4-4-12 but you would FOR SURE need to bump up the ram voltage.

did the AHCI thing fix things perchance?
