PC & MAC CLINIC - On line problem solving. (CPU)

mg, I haven't heard stories about MSN Messenger (ICQ yes). I use it regularly for a video link both ways to Italy. Works fine for the video on broadband although it's not really true video, more a sequence of stills at 1/4 sec. interval or so. Sound I don't use since it maxes out the connection and affects the performance of the video side.

Opti that was my original problem , pressing F8 or any other key wouldn't let me get to the DOS prompt , all I wanted to do was reformat the hard drive.

I can get into the BIOS set up but I can't get to the DOS prompt from there either.

Spaceman - 17 Jun 2005 09:17 - 3390 of 11003

Dil, can you boot from a CD? if youe are going to reformat you could do that from your OS CD and then do the reformat as part of the reinstall.

Your symptoms sound as though you might have a virus or trojan ;-(

Thanks mate - looks as if it's MSN Messenger then.

Spaceman , if I put a Windows CD in it comes up with a message something like

"get lost , use an emergency boot disk , then use scanreg / restore to find your missing system.ini file".

Can't remember the exact wording.

Are you booting from the Windows CD? What option are you then choosing?

Dil - 17 Jun 2005 10:39 - 3394 of 11003

From the original Windows CD when I get that message.

I don't get any options.

Spaceman - 17 Jun 2005 10:43 - 3395 of 11003

at the risk of sounding pedantic.....

Its difficult for IT people to give good advice without exact information, accurate error messages and codes are very valuable, and enable us to assist far quicker and more importantly to give accurate information.

Normally, when you boot from a Windows CD, it will start by inspecting the system and then ask whether you want to install windows. At that stage, it may also offer a repair option. If you select the install option, it will then ask you where you want to install and you have the option of deleting the existing partition and then reformatting. If you elect to install in the existing Windows directory you will be given the option of fixing the existing system.

If you run the disk without booting directly from it, the behaviour is different. I have seen some Windows disks supplied by computer makers that try to copy a disk image to your machine, but there is normally a way to get into the basic windows setup.

Dil - 17 Jun 2005 12:06 - 3397 of 11003

You be as pendantic as you like Opti , your talking to an idiot :-)

Remember once Croc advising me that kicking my tower every time the hard disk made a loud whirring sound was probably not my best option. He was right eventually :-)

I'll try swapping disks this evening and take it from there.

Cheers.

I just know that someone is going to be able to help me with this.

I need to purchase a new pc for trading. My current on (P4 1.5ghz 768m ram) is just too slow and I can't stick any more ram in it. CPU time is running permanently between 50 and 100% during the day and ram usuage is at about 550m.

This is after deleting all the spyware and paying to not to receive adverts from advfn (some of which appear to use stacks of power as they are running flash or shockwave or some such all day).

So, what's the difference between say a P4 with hyperthreading and a Xeon?
I know the Xeon's appear to have a slower CPU but there must be some reason they stick them into servers? you wouldn't after all deliberately stick slower cpu's into servers unless there was a reason.

The reason my pc currently struggles is due to the number of apps I am running. Typically I've running the following if it helps anyone give any advice
etrade
cmc
finspreads
cap spreads
IG
City Index
8 advfn L2 windows
8 money L2 windows
Streaming ftse chart from advfn
2 stockwatch from moneyam
plus some assorted other ie windows running charts or ie pages etc.

I also use outlook,excel and word during the day as well.

DocProc - 19 Jun 2005 11:21 - 3399 of 11003

Is the following assumption of mine correct?

1. Wouldn't it be a lot cheaper and faster to use MoneyAM's 'Terminal'?

2. Instead of having 16 applications open running L2, wouldn't you just have 2 Terminal applications open with 8 L2 windows open in each?

3. Is there a better or more efficient way of integrating Terminal and the windows open inside it, to save on resources and improve speed?

Any comments from MoneyAM's techies?

CC - 19 Jun 2005 11:58 - 3400 of 11003

It does appear that if you run multiple L2 windows from advfn using ctrl N it does use less ram but the trouble is I've found this setup to be less stable. Might try it out again on Monday to see if the issue was related to bandwidth as I was lucky enough to get braodband this week.

786MB limit on RAM is unusual, you presumably have a fairly old motherboard so I would investigate whether you can take advantage of the larger memory modules now available. While your checking this, find out what is the fastest processor that you can fit and upgrade it. It would also be worth checking how much disk activity there is.

If you go for a new computer, I think the Xeon processor has a lot more RAM cache and can therefore operate more efficiently on intensive computing. The Hyperthreading proccessors are designed to look like 2 CPU's so that multiple tasks shouldn't hold each other up.

Another good thing about the Xeon is that they work well with 2 or 4 on a motherboard which gives you the best of both worlds.

I doubt your current machine will be upgradeable to a Hyperthreading CPU, but if you were to fit the fastest possible and possibly get some more RAM then it may keep your machine going till the end of the yaer when dual core CPU's will be common.

I can`t get windows update to work on ` automatic`, the switch is greyed out- I am the administrator, so perhaps I turned it off- how do I negate that?

cheers.

CC - 19 Jun 2005 18:03 - 3403 of 11003

I have a Dell pc Optimist.
It's supposed to take 1GB of RAM but no what what I do the BIOS won't see the full amount. It was 99.5% stable with 1Gb but the BIOS and thus windows reported only 768 which was odd to say the least.

99.5% stable wasn't good enough for me as a full time trader so in the end my wife got one of the 512 sticks and I stuck back in a 256 which I had to start with. PC has been 100% stable ever since.

I loaded the latest bios release as well but that didn't help.


I am tempted by this:
http://configure.euro.dell.com/dellstore/config.aspx?cs=ukbsdt1&kc=npiuk4&oc=pe614201&x=13&y=8

I'll then bung say 2 or 4 sticks of these from here at 60 a throw:
http://www.misco.co.uk/productinformation/~49979~WW~/Why%20not%20get%20the%20most%20from%20your%20PC.htm

add a keyboard, mouse, dvd cd-rom etc, rob the matrox quad port card from my existing pc

and I'm sorted.


The only thing that's worrying me is whether the xeon processor is the right animal for the job or whether I should just be sticking with a conventional P4 with hyperthreading.

All I use the pc for is trading so I don't need anything with a stupidly large hard drive.

Optimist - 19 Jun 2005 19:23 - 3404 of 11003

The Dell link is not working but if it is for a cheap Xeon then you won't have a bad computer and as I mentioned above, the end of the year will see some far better hardware around.

As regards your memory, it would be worth updating your BIOS to the latest version but I suspect that there is a problem with either the memory or one of the slots. Do a Google for 'memory test' there are several available including one from Microsoft. See if you can borrow a single 1GB stick and see if that works.

Hi all

Over the last 2/3 days i have been having problems when using the betfair internet page. This is a page i have loaded every day and recently it has decided to start reloading itself approx every minute or two - it takes approx 15 secs to reload and i hence lose my opportunities to trade. No one else appears to be having the prob which makes me think the issue is with my computer, its settings or internet connection not the site.

My only two thoughts are that i am having a memory problem or my internet connection is dropping and reloading the page when it reconnects. Not sure if either are right though.

Anyone any ideas what may be causing this or a way to remedy it.

Many thanks in advance

Fundy - have you inadvertently got a refresh activated on their home page?

I've just tried, by setting the home page to refresh and then navigating to an event. On refreshing, the event page goes and the home page reloads.

Mind you, that doesn't seem to explain the irregular nature of your reloads.

Fundamentalist - 20 Jun 2005 14:57 - 3407 of 11003

Pip

thanks for the response but no, i have already checked that i have the refresh deactivated - also the refresher normally refreshes the prices without reloading the page. I have also noticed that it only happens once i have a position on an event - until i place a bet on the event it doesnt reload - im confused and frustrated!
