The above article tells you how to get into the recovery console. From the recovery console ( a VERY limited commmand prompt), you expand the missing/corrupt file from the \i386 folder where it is stored in a compressed format. (hence the .sy_ extension).
If no other files are corrupt/missing, you should be able to boot XP without any other problems. Once you get back into XP, find a HDD diagnostic program (should be able to get one from the drive manufacturer) and run some tests to verify the drive is not failing. If everything checks out OK, run a full scandisk, then a defrag on the drive just to clean it up.
Good luck, and keep us posted.

It almost sounds like you have a bum hard drive, or you are overheating badly. When was the last time you dusted out the PC? Get in there with a can of duster and clean the heatsink and fan....get all the dust out of it that you can. Then boot, and go into BIOS. You should have a harware monitor in your BIOS somewhere. See what the temps are reading at. Let it sit for about 10 minutes and report back what the temps are.
Edit: Just remembered that this is a laptop. If you are comfortable doing it, the heatsink and CPU with the fan is fairly easy to remove. These things pick up all kinds of crap. THe last one I took apart, I was able to drop the idle temp by almost 22* just by getting the dust out of the heatsink/exhaust ducting.

"safe mode the computer will only stay up for maybe 30 sec before crashing again,"
Good thing you got the important things. Just a quick guess, the hard drive is going out, or might be worse. Have you dropped it or had any glitches up to now? EDIT> Beat me by a minute. Doesn't sound good does it?

He definately has some bigger issue here. I'd put money on overheating though. I bet its a Dell laptop too. One of those things could keep half of Russia warm through the worst winters. They are notorious for running hot.

It all depends on the model. Some you have to go through the keayboard, others you can get to from the bottom. Who makes the laptop???

and i forgot to say in my last post that i think it is heat because it stayed up the longest when i got up this morning and it had been off all night.....when i started using it today and attempting to get it working it would stay up for shorter and shorter periods of time, i could be wrong though it very well could be the hdd too beucase from what ive herd if its full it is alot more likelly to crash.

Check this out.
http://irisvista.com/tech/laptops/ToshibaA65/satA65_1.htm
Read through the entire process here. This tells you how to completely disassemble the unit, which you do not need to do. You only need to get to the heatsink which is shown on page 2. You can leave the CPU installed, just remove the heatsink from it. IMPORTANT--- Make sure you completely clean the heatsink and CPU, removing ALL of the old heat compound.
Using a can of duster blow the hell out of the fan and the exhaust ducts for the CPU. You 'll know what I mean when you get it out. You will be surprised at how much dust can come out of these things. IMPORTANT--Make sure you put new heat compound on the processor. A nice thin layer that completely covers the CPU to heatsink surface. You dont need to overdue it.
Make sure you read these directions first, and at least twice before you start taking stuff apart. Its always best to read, then re-read if this is the first time you are doing this.
Good luck.
oh...you shouldn't need any special screwdrivers. Its probably just a small philips.
~Rich
Edit: You should be able to stop at step 13, clean the heatsink, then reverse the procedure. Oh yeah,...a full hard drive would not cause the symptoms you are describing. Its most likely heat.

Just be VERY careful when disconnecting ribbon cables and such. Also, you have to make sure that everything is plugged back in properly and completely seated the way it should be. Dont get too excited about turning it back on. Take your time and be careful and double check all your work as you go. If you have any doubts, backtrack and verify that everything is fine.
Good luck. Hope all works out for you. I'll be looking forward to hearing good news. I may not be on the forum for a few days (holiday weekend and all), but I'll definately check back as soon as I can to see the results.

no, just touch the metal part of the case to ground yourself. It's just to do with static. EDIT> but don't go chewing on the wires or anything. Just joking. Good luck.

Thats a grounding strap. It actually protects the laptop from getting zapped, not you. Its always a good idea to have, as it prevents static shocks from being transmitted from you to the electronics. The static can cause damage, but i dont know what the odds are. Dont take my word here as concrete, but I have worked on countless machines with and without the ground strap and have never had a problem. Again, this is my experience only.
~Rich
Edit: Now you beat me by a minute. I think we are on to something here with the heat issue. You agree Cody?

Yep, hopefully it is heat related. I'll look at some consumer reviews and see if this is a reoccurring problem.

I would say the hard drive is just about gone. Read and write errors, load errors. You may want to have someone verify that it isn't heat related. Don't throw the hard drive away. If you put a new one in or purchase a new computer. You may be able, "with a little patience and luck," to extract some of the data. It may be worth a try.
