Windows XP install probs

[slack]

Hello peeps, my first post

Right, I'm running a Duron 800mhz, Hercules Geforce 2 MX, Abit KT7A motherboard and Windows XP. I have had XP installed and running fine for ages 24/7. My proccessor runs at a steady 72C, but I'd had no lockups for months. I turned the box off for a night a few days ago and when I next booted up I got this error.

"lsass.exe System Error: An Invalid parameter was specified to a service or function"

After that the box reboots and goes through the same thing again and again. So, loop (my brother) and myself decided the hard drive might be at fault, so I ran it through a full chkdsk on another XP box. No problems there, so I reinstalled XP, downloaded SP1 and installed all the drivers etc. All was fine again till I turned off my machine and started it back up again. Same error. doh! Thing is..you can tell XP to reboot and all will be fine, but doing a shutdown and then booting back up seems to bugger it.

Anyone got any ideas on this one. I'm considering getting a new motherboard and PSU to fix the prob (already tried swapping the processor).

Thanks
John

Hello slack, a warm welcome to AOA forums!

First, is your computer overclocked?

What voltages are you reading?

I think the temp. is very high, what cooling do you have?

[Orbit]

When the Win32 subsystem starts, it automatically starts Winlogon.exe, which starts the Local Security Authority (Lsass.exe). Do you by chance have a logon screen changer running?

Also: from mskb... this *might* help.. http://support.microsoft.com/default...;en-us;Q324762

This is from the mskb on Win2K, but it *might* be applicable:

That temp will KILL your CPU..... i mean my duron 800 runs at about 75F using the stock heatsink!~!!!!

That temp will NOT kill your CPU, ignore that message. AMD specs state up to 90*C before damage to the CPU is made. 72*C is extreeeeeemly high though and you need better cooling. Also, make sure the fan on the heatsink is spinning. This could be the cause for the high temps. I'd go with Orbit's suggestion for starters and post back here for more help if it doesn't work for you.

(lets not try to scare people into newer heatsinks.)

unclemojo, Your opinion is as welcome as rain in a drought. How ever it is un-necessay to instruct others to Igor messages you disagree with. It is also un-necessary to suggest that another poster is trying to scare anyone. Especially as they stated that they were using a stock heat-sink themselves.

Information flows best when consideration guides it's transference.

AMD specs. for nearly everything user related are predicated upon STOCK usage.
Once we begin to tweak it's my view that user judgment rather than AMD specs should come into play.

But that's just me":O}

[unclemojo]

I'll just leave that one alone.....no sense starting a scuff over hardware specific specs. I'll just go with what the hardware manufacturer advises over my guesswork of what I think is OK.

Hi,

No not overclocked, but all the settings on the bios are ramped up to as fast as possible :-D

Voltages..hmmm.. can't quite remember but something like
3.4v
1.62 for the processor
11.5v
and 4.95v

The temperature I'm not worried about, basically I've silenced my PC by installing a fan from quietpc.com. The CPU is under full load all the time cos of folding@home, but its very rare I have a lock up.

Orbit, I dont think I'm running a logon screen changer (not sure what one is lol), but thanks for your suggestion tho.

Cheers
John

being his bro I'm privvy to some more knowledge
the temp is highly unlikely to be the prob, you have no idea how many months it has benn running at that temp fine. Its only suddenly now that the problem has occured. Its also strange that in 2 installs exactly the same error comes up.
I'm trying to ocnvince him to buy an Epox motherboard and upgrade, hoping that that will sort things out.

[Holst]

that temp is a bit toasty but if you can run folding and games without crashing then its probably not your problem.

Id probably be going for bad HDD on this one.
Even if it will pass scandisk on another box it might still be bad, bad memory cpu or motherboard are also a possibility.

Can you put your HDD onto loops PC install windows and use it on there for a bit. Testing for a day or two should tell you if its bad or not. If its not then try the same for CPU and memory.
If it seems the motherboard is the common factor then its EPox time

Right okay, problem solved (I hope :nervous: )

After three re-installs, it turned out to be Windows XP SP1 that was causing the problem. All is fine until this installed. Looks like theres some kind of conflict between my ye old VIA KT7A and SP1.

Ah I have a computer again :-D

Cheers peeps
John

SP1 causes problems that range from minor(my box refuses to reboot or shut down via XP-- reset button or hold the power button in for 4 seconds--exclusively) to major: Won't boot, that's all she wrote.

Annoyed by this "no reboot, no shut down" problem, I removed SP1. Always say yes to the "you wanna make SP1 uninstallable?" feature. Then the box rebooted roughly half the time, and shut down via software about the same. With gaping security holes, of course. It's always something.
