Standby and restart problems

Hi guys,

A few months ago I built my first PC

. Spec as follows:

CPU: Intel Q8400
Mobo: Gigabyte EP35
VGC: BFG 9500
O/S: XP SP3

My problem is this, 9/10 when I put the PC into standby mode I have to do a complete reboot when I return to the PC as I get 1 long beep followed by 2 short ones. I then have to press the reset button in order to get the correct one beep. :confused:

The same thing happens when I have to restart the computer after installing software and updates.

After I had finished the original build I also had problems with booting up, but solved this problem by shorting out the CMOS jumper pins and resetting the BIOS to load the optimized defaults.

I would be really grateful if someone can solve this problem.

Many thanks,

Hi PLec,

The BIOS have remained pretty much the same since I solved the original booting up problem. I have enabled USB keyboard and a few other things but have not changed anything radically.

I will check the memory settings and the operating voltage along with the possible vCore issue; will post back later and let you know!

Many thanks for your input.

Plec,

Apologies for the lenghty delay in getting back to you!

The Vcore is set at 1.268v and the operating voltage for the memory is 1.872v.

I am very wary of messing around with trhe voltage settings in case I end up with more problems than I solve!!

Thanks,

Hi EsaT,

Thanks for your reply; I downloaded a data sheet from Kingston's website that stated:

Kingston's KHX8500D2K2/4G is a kit of two 256M x 64-bit 2GB (2048MB) DDR2-1066 CL5
SDRAM (Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR2 FBGA
components per module. Total kit capacity is 4GB (4096MB). Each module pair has been tested to
run at DDR2- 1066MHz at a latency timing of 5-5-5-15 at 2.2V. The SPD is programmed to JEDEC
standard latency 800Mhz timing of 5-5-5-18 at 1.8V. Each 240-pin DIMM uses gold contact fingers
and requires +1.8V.

What confuses me is that in the blink of an eye it gives two different voltage settings of 2.2V and 1.8V. As mine is currently 1.872 is that enough bearing in mind my PC boots up with no problem when initially switched on?

Any help will be gratefully accepted.
