Cmos checksum error

I am building a new computer with an asus motherboard model p5n32-e sli with an intel pentium d 3.2gz cpu and I 1gb of ram memory and they are from Corsair TWINX 2048MB PC6400 DDR2 800MHz E.P.P. nad western digital sata 500gb hard drive.
I will power the pc, not hear any beeps see the bios screen and sometimes see the cmos checksum error and the pc will power off. I try turning on again and it just off faster. If I want to see the bios screen again, I need to leave it off for a while.
I'm not sure where I went wrong.

Re: cmos checksum error

Cmos checksum errors are caused by a bad battery.
If that dont work then the board is bad from the factory.

I have a p5n32-sli deluxe motherboard. Do you know if it suports the intel core 2 quad processor Q8300?

The highest you can go is a Pentium Extreme ED-965(3.73GHz, rev C1), it will not support the Core 2 series

:CMOS Checksum Bad error Hi, My system had intel c2d 2.13ghz processor and 2gb ddr2 ram to begin with. I recently added 2gb more (both are 667 mhz). Now i'm getting an error while booting which says CMOS...

Yes--most probably a memory error.
If you added memory and kept the original memory, they might not be compatible.
Try running with only the old memory.
Then try running with only the new memory.

Bet both work. But not together.

Asus P5n32 Sli Premium

There is a couple of things you can do to troubleshoot this.
If there is an on-board VGA (video) port on the back, try that.
Clear the CMOS. On that spec board there should be a coloured plastic jumper next to or near the motherboard battery like this >>>>>
If there is no jumper then remove the power cord from the back and take the motherboard battery out for half an hour then replace and see if you get a post screen.
If it still suffers from the same symptoms then there could be micro fissures between solder points on the motherboard as Intel's tend to run fairly hot.
This means you have to re-float the motherboard and is a last resort repair.
If you need anymore help or advice please post back.

Good luck.

Replaced RAM; PC keeps shutting down?

2 suggestions:

1. Make sure the CPU cooler is on properly.
2. Check your power levels. I had a computer which did this. Turned out to be the PSU which eventually died. A different PSU has had the board going for 5 days now, instead of 1 day or just a few minutes.

No boot, continuous Beep

I would take the CPU back out. Remove the excess thermal compound, you should only use a very thin layer. Make sure the CPU is oriented and seated properly.

Extreme slow performance, cpu performance maxed out

Boot to safe mode and see if the problem is the same.
Have you checked for viruses and spyware?
Look in Control Panel/Admin Tools/Event Viewer, System and Application for red marks.
Do you have a temp monitor installed?
Have you changed anything in the BIOS? Set to safe defaults.

Intel ASUS P4 845 GL Motherboard

Hi, For an ASUS P4BGL-VM Intel 845GL Chipset Ultra ATA100 MATX CPU Type: Intel Pentium 4 478-Pin (OEM), the Asus site specifies max of 2 x 184-pin DIMM Sockets support max. 2GB PC2100 / PC1600 non-ECC DDR or SDRAM memory but not "and". Personally, I find it more practical to install 2 X 1Gb rather than a single 2Gb. Hope this gives you some idea. Kind regards.

New Installation P5N32-E SLI

There is also a 4 pin power connector cable for the processor to connect onto the motherboard. Make sure that is plugged in. IF that still doesn't help, disconnect hard drive, video card, cd rom drive and floppy drive and any other pci cards in the system. Try booting it again at least to the bios. See if that helps.
