Update: My disabled computer

Back again with an update on efforts to resurrect my ailing Acer Aspire L100 home computer.

I’ve been overwhelmed with helpful suggestions from Computer Corner Blog and Newsletter readers; if I haven’t yet replied personally to your submission, I apologize. I do read all my e-mail!

Briefly, the L100, running Windows Vista, started spontaneously rebooting itself after about two years of use.

Several of you suggested this could be a heat-related problem. Since my last report, I have disassembled the computer, which is not easy because as an ultra-compact desktop model it’s designed more like a notebook — everything is really scrunched together inside.

I vacuumed the air intake and exhaust ports on the case, around the cooling fins and wherever I could find dust inside.

I removed and re-seated the two 1 gigabyte memory chips.

I tested the integrity of the memory using both the utility on the Windows disc and a DOS-based software utility.

The hard drive has been checked out by a software program from the model’s manufacturer.

No USB peripherals are plugged in (except for the keyboard and mouse that came with the system).

But even after all that — and my willingness to sacrifice the contents of the built-in hard drive (all my data is always stored on an external USB hard drive) — I still can’t get Windows Vista or Windows 7 to install or run, even though the open source Ubuntu Linux operating system loads and runs right along without any problems.

In desperation, I did contact Acer by e-mail, only to be informed that I would have to part with $60 for a half-hour of time with a telephone tech support representative to get any official help.

No thanks.

My quest continues. I may eventually have to invest that $60 in a new computer, but for now I think I’ll continue puzzling over the L100.

I enjoy challenges.

Ever consider a Mac? They have Apple stores in the metroplex and their technical support consultations in the store are generally free…

…just a thought.

I had a similar problem a couple years ago on my desktop pc. I did a slowdown of the cpu bus speed thru the bios and the problem went away. I sped up the cpu bus speed back to normal and the sproadic reboots would occur. I thought some sort of cpu damage had occurred (i.e. overheating damage). I replaced the cpu itself (slightly faster) and put on a new cpu fan, kept bus speed at original speed and it has cleared up the problem. Haven’t had a problem for the last couple years. Only other check would be the power supply – is it not as consistant in the voltages being supplied to the components. You can see thru the bios or perhaps some motherboard software.

Have you tried a different keyboard? What you are describing is frequently caused by static electricity. Moving your hands over the keys, touching any part of the computer, or perhaps even an unknown spill by family members who haven’t confessed(yet)are signs of shorting problems.

I had a computer do the same thing last summer.

It turned out to be the power supply. I did the wrong thing and used the machine far too long … until it wouldnt’ boot up at all.

The power box had actually caused some resistor looking components to “bubble up” it had become so hot. I had to buy a new machine.

Something tells me you’re a lot better off than I was, and that, if you replaced the power supply, you’d be good to go.

And thank you for reporting this. It seems to be a more and more common problem with machines. My guess is that antiviruses and new OS’s require a lot of computing power. And I used to leave my machine on 24/7.

I Left Comments on the last Thread how ever
Submit up www.Cpuid.com for great bench mark tools
www.Malwarebytes.org for Mal ware removal tools
and try the UBCD4WIN i really find it packed full of
LEGAL and useful tools.

My l100 started doing it recently, just shutting down by itself. Can’t remember if it was doing it with Vista, but I recently upgraded to Win7.
