I am working on a friend's computer. They have an Acer Aspire M5640 desktop with Windows Vista Home Premium. They initially called and told me the system would not boot. When I took a look they turned it on and the monitor said "no signal." There is no splash screen and I cannot even see the POST. I brought it home and tried it with one of my monitors. Same thing; nothing showed up on the screen. The blue power light turns on and the case and power supply fans work when you push the power button. I opened up the case and removed the RAM and disconnected and then reconnected all cables. I tried it again and still no luck. Has anyone else encountered this? Should I try to install a new graphics card in case the onboard graphics card has gone bad, or could it be the MOBO? Any help would be greatly appreciated.

Hi All Just faced the same problem with my 2yr old M5640. Power up but no POST. Tried the 'REMOVE YOUR POWER CORD AND HOLD THE ON BUTTON FOR LIKE 30second TO A MINUTE AND THEN CONNECT IT BACK AND TURN IT ON' but not luck. BTW what does that do? Anyone figure out whats wrong and how to get it boot, at least to POST.
I have an old HP media center 2005. I added a graphics card 2 years ago. Today I get no signal to monitor. I disconnected my video card and connected the monitor to my video chip which came with the computer. The monitor is working fine. It looks like a bad video card for me.
I just recently joined the masses with this bogus integrated graphics card. A techie friend suggested installing a PCI Express graphics card with the hopes of bypassing the faulty card on board. Has anyone tried this and did it work?
The answer posted by Orten999, i.e. reinitialising the computer by pressing the ON button, without the power cord plugged in, for 30-60', worked for me. I thought I was going to have to put a new computer back in the box and take it back to after sales... The machine is not a M5640 but a X1430 desktop computer by the way. THANKS. :)
