Try reloading BIOS default setting by removing CMOS battery for 30-40 sec and then putting it back (if you have another, try replacing the old one). Next, pull the memory out and try booting. If you hear beeps your memory was OK and it is most likely that your motherboard is bad. If you do not here the beeps, Try testing memory by reinstalling one stick at a time or possibly replacing memory. It is very ulikely that your CPU is bad.

Reasons could be:
1. BIOS battery is dead.
2. RAM chip has loosen up in the slot.

Open the CPU, and look for BIOS cell (it would look like a quarter coin). Try replacing that. Also check for RAM; take it out clean it with a dry cloth, blow the slot with dry air to take out dust particles and place it firmly back into the slot.

Hope this would kick start your PC again.

No device acer video capture


You can check if it (the camera) appears in Device Manager. Right-Click "My Computer" (or Computer in Vista and Windows 7), click "Properties", click Device Manager, then look through for your video/web camera.

From your description, the camera may be defective. If your computer is under warranty, I would contact Acer (or where ever you purchased it, depending on where you purchased it from store versus Internet and how long ago you purchased it, etc.) to get it fixed under warranty.

I want to downgrade ACER ASPIRE M5641 desktop form vista to XP. What steps to follow? Also I have only the backup CD which I made right after the purchase , originally installed with VISTA. Understand it...


You'll have to purchase the XP software, set your computer to boot from cd (in the cmos settings), put the disk in the cd and restart you computer. When the screen comes up to "...hit any key to boot from cd" hit any key. The system will boot to the XP cd and will allow you to delete the old partition, reformat your drive, and install XP. Next go to www.acer.com and download your drivers. Finally install your programs and data on to your hard drive. Have fun!

NOTE: Make absolutely sure that you backup the programs and data that you want to keep before starting the XP install!

Computer wont start acer aspire L-100


CPU overheated? When you cool it down it will start. You can check whether there are lots of dust on the CPU fan and the chase of the machine, they might block the air flow and overheat the CPU.
