My first thought is that you are right. My second thought is that your computer is probably a couple of years old and some power supplies will wear out. Especially if there's a lot of dust bunnies running around. I'd first take a vacuum to it. Put the vacuum right on the fan of the power supply and let it spin it up, then move it to a spot opposite to that. If you can, remove the case side and vacuum inside as well. Get all the nooks and crannies, but be careful you don't knock anything loose. No guarantee it will help, but it just might.

My Acer Aspire M1201 Desktop will not boot. I turn the power on but all I get is the Acer logo followed by "No Signal" and the monitor goes blank. I keep hoping I will finally hear the beep noise...


If you are seeing the Acer logo on boot up then the machine is working. The problem will be your graphics drivers being corrupt.
Try starting the machine in Safe Mode. To do this repeatedly tap the F8 key as it's just starting up. It should take you to an advanced menu with Safe Mode at the top, select that with the cursor keys.

If it allows you to boot in safe mode then wait until Windows loads and then right click on My Computer/Computer, select manage from the sub menu and then Device Manager.

Click on Display Adapters and uninstall the drivers. When its done unistalling the drivers restart the machine in normal mode. It should boot into Windows. If it lets you boot into Windows I suggest that you download and install the latest drivers from Acer's support website.

If you need anymore help please post back.

Good luck and regards.

Boot up

Ok, all I can suggest it to do it all again. If this doesn't work, you will have to get a Windows install DVD, and then, put the, Windows Install DVD in PC, set BIOS to Boot from DVD, boot of DVD, bootup off DVD, and try and perform a "Start Up Repair" if that doesn't work, then you will have to do a full re-install of that Operating System. Ensure you Format the drive NTFS, and then install Windows. it would also be a good idea, to go to the ACER site, and download ALL Drivers for your PC, put them on a Flash drive, or burn to DVD, now you will be able to install the correct drivers at install time. This is often a help, if the Ethernet,or WiFi drivers don't work, and one couldn't get on the 'net to download.

I have an Acer Aspire 5672, it just cut out & wont power up at all, Battery okay & power supply from mains ok (been tested). It just switched off & wont boot up again. Battery is charged &...

One thing you might try is to unplug it from the adapter and remove the battery. Let it sit a few minutes and replace the battery and try to start it again.
If that doesn't work, then plug it in and try it again.
If it still won't power up, you are probably looking at a motherboard that has gone bad. If it is still in warranty, then the company should fix it.

Acer t300

Open the case ( i take it your warranty has expired ) and check all connections, unplug the wires from the powersupply and plug them back in, when you try and switch it on, do any of the fans start spinning.. you probably have a dead CPU of motherboard..

Determine what CPU you have and borrow the same socket type from someone else if you can, slot it in and check, works = dead CPU

Good Luck
