I was using irfanview to resize some photos when, after saving one such photo, I went to click on "save as" but instead of the photo being saved my computer froze. The mouse pointer wouldn't move; control-alt-delete didn't work on my keyboard and when I tried to shut off the computer by pressing the "button" on the top of the tower, that didn't shut it off either. I then pulled out the power cord on the back of the tower and that shut off everything. I waited ten seconds and then put the cord back into the tower. Now the monitor starts with the blue light and Acer screen but then it says NO SIGNAL and the blue light turns to white. The mouse doesn't seem to work (the red light that usually shines on the bottom of the mouse when it is working isn't coming on) and the keyboard isn't working either. In fact I've tried 2 different keyboards and neither are working (there is usually a blue light that comes on when the keyboard is working OK but it isn't coming on). The speakers are working OK and the CD-DVD ROM drive opens and
seems like it will work OK but since the monitor isn't accepting any signals from the desktop computer, nothing I put in the CD-DVD drive shows up on the monitor. HELP!!!!!!!

Luckily I bought a laptop computer recently so while I can use it to get on the internet and check things out, I want my desktop working OK too. Might it be a motherboard issue or power supply or something else? Not handy fixing computer, just using them.

The computer is an Acer Aspire M1641-U1521A and I upgraded it to Windows 7 Home Premium 64 bit. I've had it for just about 2 years.

Hello and welcome to Bleepingcomputer.

Does the computer post at all? Any Post Beep codes?

If you can get a video on the screen, you should try entering the BIOS setup screen and set defaults, then save and exit.

If your getting a post, but no video, try re-seating the graphics card, then booting up again and entering your BIOS setup and set defaults.

If this continues to happen, try doing the PSU again, with unplugging and replgging your power supply power wire, sometimes this re-sets the PSU.

Please keep me updated with the results.

Bruce.

Okay opened up the computer and the power supply seems to be working OK (I can do a hard reset by holding the power button down for 3 seconds and it shuts off and comes back on when I press it again.) I checked the battery for the motherboard and that looks like its working OK. Not sure where the graphics card is so I might have to take the Acer tower to a repair shop and have them check it out. I dont want to do anything that might make things worse.

Okay, I can understand your concerns and if you're really not comfortable with working on your own computer, it is always best to take it to someone who has the knowledge and training to do it correctly.

Good luck and if you wish to post back what was found to be wrong with your computer, we would appreciate you're doing that.

Kind regards and good luck.

Bruce.
