So I've had some problems with my computer for the last few days. It started with the computer not waking up after going into sleep mode. The power light would go from blinking to on, it would sound like it was on, but I would get no signal to the monitor, keyboard, or mouse. I reseated the RAM once and that took care of the problem for a day or so, then it started up again. One time it did seem to wake up but the computer just showed a blue screen with a large black rectangle in the bottom corner (NOT a BSOD). Now the computer won't shut down. I tell it to but instead it just restarts.

chkdsk is clean, virus scans are clean.

Event viewer comes up with a lot of Event ID 55 NTFS, as well as 7036 Service Controller.

The computer is an Acer Aspire AM5640-U5403A. I've had quite a bit of problems with the mother board - its been replaced twice under a service plan, so I'm wondering if this mother board is shot as well.

If it is still under warranty then that is the way to pursue the problem. While there are many here more then capable of assisting in trouble shooting, I believe they would recommend the same.

To much self trouble shooting could very well void you warranty. Leaving you with an expensive paper weight.

I do not know your geographical location but be aware there is a "Lemon Law" in the U.S. The manufacturer, Acer in this instance, has three attempts to resolve the issue to the End Users, your, satisfaction. If in three attempts they fail, the End User has the right to expect a totally new machine of equal or greater value to the current problem PC. This is of course only if the original machine is still under warranty.

The machine is no longer under warranty - the previous problems were fixed by an after market service contract from Fry's.

Reseatting the RAM has resolved the issue, just like it did before, but I feel like it's probably going to come back, as it did last time.

Then the first thing that comes to my mind is to test the memory.

You can obtain Memtest86+ here.

Under About Memtest86+ > Download (Pre-built & ISOs) > under ** Memtest86+ V4.20 (25/01/2011)** > Download - Pre-Compiled Bootable ISO (.zip)

Extract the. zip then go to the folder that was created when the .zip was extracted and burn the .iso file to a CD as an image\.iso. Restart the troubled machine with the disk in the optical drive. Be sure the BIOS are set to boot from the optical drive first.

Do this when you will not have need of the machine for a while as you will want to let it run for around 8 hours to get the most reliable test results.

Should you have any questions regarding the above instructions please ask.
I`m going to look up some specs and info on your lap top. I take it you are from the U.K.(?).

Found an Aspire M5640 on the Acer Europe site. Should Memtest not show your memory to be possibly at fault then we can verify that I am looking at the right model and try a few other things.

Regarding the Event ID 55 NTFS. I see several cause\cures being posted for this issue. One states that to solve it some have had success restoring the power options to their default settings. That is if you had made any changes to them. This does somewhat relate to your on\off issue. Might be worth a try.

Infirmation about the 7036 Service Controller.
