Repeatedly starting PC
by popeyedasailorman / July 11, 2005 7:28 AM PDT

Seems very likely that your installation of XP is corrupt, if it can't find a system file it needs then it will reboot so if the file is missing or corrupt then it will just keep on rebooting over and over, if you have got one, put in the Windows XP CD, boot from it and after a while you should get an option come up that says 'Repair using recovery console' choose this which will then take you to a black screen, then type 'chkdsk' this should help, if not you might need to reinstall XP

or it could be your memory

that's going bad. Some motherboard do not do the memory checking on startup. If your memory is from a couple pieces of ram, leave only one of them then turn on your PC. If it works normal, than that piece of ram is good. Repeat this until you find the bad piece.

It could be any other reasons....

hopefully not...

i don't think it's the memory because in setup it recognises the 512 module that's installed, i suppose if the memory was the problem it's unlikely that it would recognise the memory.

I'll share that the item you wrote is "not good enough" a test to rule out the memory. I don't want to start a debate about it, but write because I've seen systems with good RAM that passes MEMTEST86 fail latter and the memory was the issue. I'm not writing it's your issue, but your parts list is a common site at the repair shop. Here's the short rundown.

1. The dust is removed.
2. Fans and CAPACITORS are checked.
3. A quick "is this system a good one" made. i.e. we see if there is a whopper power supply and the voltages are in spec. Hint: Use a digital voltmeter.
4. The BIOS is updated and we try it again with the BIOS's safest settings.

response to your points bob

hi bob
thanks for the advice,

well i must admit its quite dusty could do with a clean.

as for the fans and capacitors pretty sure they're fine, the fans definately are.

the system meets all requirements i built it myself piece by piece and has been fine for 2yrs+.
(i know the twinmos memory isn't the most reliable but if it wasn't working surely it wouldn't be recognised in the BIOS)

the BIOS is up-to-date if not the most recent the one previous and was always fine before.

i'll double check the capacitors (spelling?) again to make sure and i'll give it a clean see if that helps.

again thanks for the advice peeps, i'll be back if theres no change.

I meant "sight", but here's a picture of the capactor issue we see too often ->

I see you never listed details about your power supply. It would be nice to know the wattage as well as the results of the digital Voltmeter readings. And no, you can't rely on the motherboard bios voltage reports.

memory problem and thanks :)
by Nienna_2 / July 29, 2005 12:34 PM PDT

Hi Lath,
I just wanted to thank you for your suggestion of checking the sticks of ram. I have been having many problems with installing and pc restarting and shutting down, I had tried everything, and i was just about to try MS recovery methods when i read your email. I tried removing sticks of ram one by one and the problems stopped!

thank you!!

try this if you have sp2
by gopinath_sastra / July 12, 2005 9:01 AM PDT
In reply to: no cd boot option???

there could be "n" number of reasons for the computer to reboot automatically
may be it could be a hardware or registry and more reasons
so to find why exactly it reboots try to disable the autamatic restart on system failure
tap f8 when the system boots and then in windows advanced options select disabled automatic restart on system failure(this option is available if sp2 is present)
let us what is the blue screen error message you get and we can proceed from there on
if you cant boot from the cd try creating xp boot floppies and boot to recovery console and perform 307545
article 307545 will see u through if this is not an hardware issue

Had the same sort of thing happen to my PC. Took it to shop. Shop said it was the harddrive that would not let the setup continue. Had to buy a new harddrive. Have a new haddrive and everything operating okay now. I really hope that this has not happened to you.

XP boots repeatedly
by TomsterQ2 / November 10, 2009 11:21 PM PST

If anyone else has this problem... I ran across the same problem. Turned out to be a worm that autoruns named browser.exe located in the c:\windows directory.

I removed the drive from the machine. Hooked it up to another PC using and Hard Drive to USB adapter cable kit (part number USB-DSC5) and then scanned the entire drive using MalwareBytes software.

For some reason, malwarebytes finds the weird worms and malware that other AV/AS products miss.

Once it removed the worm, the machine booted into checkdisk... which I let run to completion... it then rebooted again and this time booted normally.

Hope that helps someone else... seems to be a lot of these repeat boot issues being reported on the net in the last few weeks.
