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

Thanks Kayak. I assume that these batteries are available from Maplin or similar?

I will have to dig out that manual again!

Kayak - 02 Mar 2004 08:00 - 1405 of 11003

I would have thought a jeweller's/watch shop should have it 2Abbey...

Spaceman - 02 Mar 2004 08:07 - 1406 of 11003

2Abbey, I am pretty sure it the battery as K states. I think the 2 BIOS's are there in case one gets corrupted not to cover a failed battery, if you missflash a BIOS you can end up with a dead motherboard, some of the motherboard manufacturers have backups where you use a floppy and some beep codes and some have dual BIOS like yours and some dont have an easy method, if they have a removable BIOS chip they can be resurected but if they dont its often too expensive to sort and the best solution is a new motherboard.

If a change of battery does not rsolve this I would suspect a motherboard fault.

Back to my cpu usage issues as still not happy although things improving.

A couple of observations - even at 20:00 with only stockwatch running my cpu usuge varies between 5 and 15% (no other apps loaded at all). As soon as I close it cpu drops to 0%.
On this page my cpu usage runs at 0% when I am not typing
On moneyam home page my cpu runs at about 10% just viewing it
On advfn home page cpu runs at about 15% just viewing it

Is it all this damn advertising that is using my computers resources? Is that possible?

Kayak - 02 Mar 2004 21:03 - 1408 of 11003

Yep, the animated advertising, paricularly the Flash ads, consumes a significant amount of CPU. You can see the difference by turning off "Play animations in web pages" in Tools/Internet Options/Advanced.

Having some probs with the remnants of the Code red virus. Norton and all the other virus checkers say it is no longer present but something is recreating c:\explorer.exe
Any ideas?

Kayak - 02 Mar 2004 21:54 - 1410 of 11003

Are you running a Windows server without realising it, Croc? Easy to do with Windows 2000 since IIS is enabled by default on installation and is unpatched to start with of course. Check Internet Services Manager under Control Panel/Administrative Tools. I think the explorer.exe file is the file that arrives via the exploit and is then run to cause the damage. It may not show up in a scan until you reboot and execute it via the run commands in the registry.

Optimist - 02 Mar 2004 21:56 - 1411 of 11003

Croc

The string "c:\explorer.exe" should not appear in the registry at all. It may be worth searching for it.

CC - 02 Mar 2004 22:06 - 1412 of 11003

Kayak- have turned off those animations - yes the difference is very noticable.

Spaceman - 02 Mar 2004 22:10 - 1413 of 11003

croc, sometimes its worth going through the manual remaoval checks toi ensure the thing has been eliminated, i have seen bits not get removede by the stingers and tools. Here is a link with info about code red if you page down you will see the manual removal instructions.

[edit] i didnt actually read the manual instructions for this worm but I just have and they dont help much. Often symatic list all the files and registry keys involved but not in this case. SO apologies for some useless info...

[edit 2!] There is also a code red ii and here is the link for that in case its the version you have, this contains more detailed technical info.

I've just managed to delete Windows Explorer... Does anyone know how to get it back?

I've just started using XP Pro after several years of Win 98. I've tended to use Windows Explorer quite a lot for moving files around, copying documents, etc. Because it's so handy I prefer it to be on the first start menu rather than buried. So I tried to copy it from All Programs -> Accessories to the first start menu (the one you get when you click on start). Something went wrong and its disappeared completely. I have a shortcut "Windows Explorer (2)" exactly where I wanted it to be, but it doesn't work because can't find the necessary file...

PeterG
This is where mine is, hopefully yours will be in the same place.

C:\Documents and Settings\Start Menu\Programs\Accessories

or C:\WINDOWS\Driver Cache\i386

or C:\WINDOWS\system32\config\systemprofile\Start Menu\Programs\Accessories

PeterG - 03 Mar 2004 13:32 - 1416 of 11003

OK, it's back. Thanks, Prodman.

can anyone help, i need to creat a start up flopy disk for windows 2000 pro

Spaceman - 04 Mar 2004 10:44 - 1420 of 11003

ll there isnt really such a thing, can you detail waht you need to do?

Lancslad - 04 Mar 2004 10:53 - 1421 of 11003

spaceman i intend to wipe 2000pro from my spare comp and reinstall windows 98se

Spaceman - 04 Mar 2004 12:15 - 1422 of 11003

ll you can download bootdisks from www.bootdisk.com and then boot the PC using that, I suggest you use the Windows 98 version, you may be able to boot directly from the Windows 98 CD-ROM, have you tried that?.

Lancslad - 04 Mar 2004 12:43 - 1423 of 11003

thanks spaceman will give it a try l.l.
