Intel i5 2500k + Asus P8P67-M problem!

2smoothbooth · 25 Jan 2011 at 18:24

For some reason I cannot get my new system to boot. There is power to everything, no error beeps, my vga bios shows up but not the motherboard bios.

Here are my specs:
- Intel i5 2500k
- Asus P8P67-M Motherboard
- 4gb Corsair XMS3 DDR3 1600 MHz
- 7900gs
- Corsair 450w VX

I have cleared cmos, removed the battery, resat the memory in different slots (one stick at a time) but nothing. I have also reseated all other components and done the normal troubleshooting business. Anyone else have any idea's or can tell me the guilty component?

Thanks

Any fans turning on? HDD activity?

Yep fans are doing their thing. As for HDD I have disconnected everything to narrow down the problem, even with everything disconnected (except for the main components) it should boot to bios...at least :s

This is the exact same issue I have. You'll need to clear CMOS, probably pull the battery and power cable out for 10 mins, boot with one stick in slot A1. If you dont have the the RAM led on it will hopefully go into bios. If it does have the ram led on, you'll need to hit the detect ram button (if the -M version has this) then once it finally boots you'll need to manually set the memory command rate under timings to 2T, save and reboot, check it still boots, switch it off and install the other ram stick. Use the black slots not the blue ones like the manual tells you.
Then update the bios.

Finally you should have a bootable system - Im sure its something to do with detecting memory timings correctly with certain CPU's. Funnily enough SimonMaltby has had one CPU do this on his Asus and another CPU (exactly the same model i7 2600k) work perfectly no issues.

Please can you go over to http://forums.overclockers.co.uk/showthread.php?t=18233797
And post you're CPU batch number and the other bits and peices requested so we can start to put together a picture of whats causing this. Cheers

thanks for the reply. I did manage to get it to BIOS screen once but I turned it off thinking it was working :/ I will try your method and post results.

I appreciated your suggestion rustEswan but it has not worked for me. Still not booting in to bios and still no error beeps which I find inconceivable. Any other suggestions before I RMA the board? Or could the culprit be the i5 2500k?

FIXED: Thought I'd let everyone know that the problem was actually my power supply :rolleyes:

Its a Corsair 450w VX which for some reason works fine in two other machines i've tried (sockets 775 and 478) but not the 1155. Tried using 8 pin and 4 pin to get it going and still wouldn't post for me. Popped it back in the old computers and worked fine. Perhaps there's a technical reason why it doesn't work but hopefully this will help someone else experiencing the same problem.
