Whats causing this?

stevejazzx

Ok I migrated my PC into a new case, a bigger one and since I have been having some issues.

1. I get checksum error press f1 to continue (if i change the multiplier in bios to 4:5 this goes away but each time I had new hardware it defaults back)

2.My cpu is being read as an athlon when its a sempron and the cpu clock is 1.6ghz when it should 1.8ghz(a sempron 3000+)

3. The ram reads as 0.98gb instead og 1024

Comp spec is

amd sempron 3000+xp
1024 pc 2700 ram
win xp pro
on board sound and video
330watt psu

i'd recommend a bios update first of all.

Try popping the batt out of the mobo to clear the cmos and then put it back in a reboot - this resets everything and might help.

just popping the battery doesn't always do it... unless you leave the battery out overnight. There's usually a jumper sitting next to the battery that you need to shortcut to clear the BIOS instantly. Did you change any hardware as well (like a new motherboard e.g.)? Or just moved all components from one case to the other?

Only added extra ram and put whole thing into new case
Have popped the battery out and reset jumper but havn't had the battery out overnight?
Looked on ASUS site for bios upgrade and its a big rigmorole surely theres an easier of updating bios?

If you follow the rigmorole it's not that complicated to flash the bios.

its just not explained very well, its messy and seems to of been written by someones who first language isn't english but I'll give it a bash, was thinking there shoud be a win utility fir this or something!

Do you still have the old RAM. You could try to boot the computer as it was in the old box first. I think the problem might me with your new RAM.

If you use the jumper there's no need to reset the battery at all. Some motherboards don't have a jumper to reset the BIOS in which you need to remove the battery, and as there's a condensator still charging the BIOS for a while you need to leave the battery out for a few hours to clear the BIOS completely. Using the jumper will clear the BIOS instantly though, so no problems there. Have you tried removing the new memory stick? Just to check if it's not a memory conflict.
Also check your current BIOS settings, most of it is self-explanatory and if you don't know what something is/does, better not to touch it.

changhed ram old in the old case and was fine added extra ram to it in the new case
I've been googling this and some places put it down to a psu problem and this is interesting as i got this new case from komplett (cheap inwin one) that was supposed to have a 430psu but on the psu itself it says 330watt total output and when I emailed komplett about this they just said i was wrong!

If you still have the old case you could try using your old PSU and see if it boots up properly.

I'd go with the CMOS reset jumper first, the press F1 error is usually something to do with user-configurable changes that have been made - any recent tinkerings?

Apart from that, BIOS flash, swap PSU, etc

Realistically, if all you've done is change case, the PSU is the only functioning component so that would be the logical choice, but I can't see how myself.

well i've reset cmos and updated bios and still getting this
apparently if psu is insufficient the processor wont run fully (something to do with voltage???????)

tbh the spec you give above doesn't sound like it would come remotely close to 330 Watts. Just in case, try disconnecting your hdd drives and CD drives. Moving parts use most power.

Checksum error means that the bios settings are muddled (the checksum doesn't match the contents). You may have screwed them up if you let the board rest on a metal surface while you were moving it. Check the motherboard mounting screws aren't touching off nearby tracks or components. Unless theres a copper ring around a hole, they didn't intend to make a ground connection there, use the little plastic washers to insulate the board from the screws.

Can you go into the bios at all ?
If so, load bios defaults & reboot, see how far it goes on lowest performance settings.

-edit: re-reading your first post, I understood it differently. Its losing your settings when your reboot.
Get a new CMOS battery.

Dunno bout the CMOS batt - there's been one main hardware change recently and if everything was OK in old case then I doubt the batt's the problem. And OP said that it was every time new hardware was added, not when rebooting.

The mobo idea is interesting though, could be that.

its not that i thought the psu was too small just malfunctioning somehow although that sounds implausible
you know i think you may be right about the mobo not being grounded properly only thing is there is a screwhloe on the mobo which is empty where a riser screw should be but there is no coinciding hole on the case for it so it is just left empty, would this a make a difference, also the mobo is really close alomost touching if not slightly touching some of the pci slots????

Some motherboards are just picky about hardware changes. I have an Asus CUSL-2C here that has about a 1 in 2 chance of resetting the CMOS settings to failsafe on any hardware change. I don't see it as a problem as I rarely make any changes and it only takes a minute to enter the correct settings when it does happen.

3. The ram reads as 0.98gb instead og 1024

Onboard video uses a small amout of system RAM. You can normally select the amount to be allocated in the CMOS setup (32MB,64MB,128MB,256MB). A larger allocation allows selection of higher resolutions/greater colour depths in the OS.

ok yeah i had resigned to this much but can't figure out why it reads the sempron as an athlon or why its clocked at 1.6 instead of 1.8

Steve can you clarify something: Before you made any change whatsoever to your system, (ie. old case, no extra ram) was the Asus motherboard correctly identifying your processor as a Sempron?
It just doesn't make sense to me that without any modification (such as bios flashing)a motherboard would incorrectly identify a procesor which it previously correctly identified.
One of the commonest questions that people had with Socket A Semprons, when Semprons first appeared, was that many motherboards identified the chip as AthlonXP. The solution was usually just to flash the bios to a newer version and the chip was then identified correctly. What I have never encountered before is a situation where a motherboard that is correctly identifying a Sempron stops doing so for no apparent reason, and reverts back to calling it an AthlonXP. Hence my first question.
Older AthlonXP models (like the Thoroughbred core models up to 2400) and Socket A Sempron are very similar chips so even when the cpu is misidentified the system should run reasonably well.
Also tell us what model your Asus motherboard is. We haven't really got much detailed info from you and if we knew the model we may be able to advise more on what to do.
Also go here and download CPU-Z. It's a freeware program that'll tell you a lot of stuff about your system, including which BIOS version your motherboard is using.

Yeah well exactly thats the mystery in the old case I could see the cpu as a sempron, but now its says an athlon??????????????
since the move i have swapped around the cd drives added a hardrive and memory

anyway mobo is
asus a7s8-mx
and the computer semms to be running fine but i would like to fix this

There is... AsusUpdate (on your motherboard CD)

Just download the latest bios and use the app

It's a fairly simple GUI, i fail to see whats hard about it :P

peepsbates

dunno if this helps but here goes..... i had a prob with checksum error when i removed the cpu to put thermal paste on when i put it back on i got the error on restart, i set bios to fail safe defaults n i aint seen the error since. if im wrong plz disregard;)

gline

can u run a memtest at all? if u changed ram, maybe that is faulty.

Also as mentioned, have you tried chosing load defaults in the bios?
