My Acer aspire 5610 won't boot. I have no screen at all. Not able to enter Bios. I reseated RAm,HD, followed all online advice but nothing works. i get one long and two short beeps dvd spins and hd is working too

This generally indicates a bad HDD...but enter the bios and make sure first boot device is NOT set to Network in the bios or maybe the hdd has gone and its looking for a operating system to load....
Check cable connections (reseat),
Check jumpers on hard drive for Master/Slave or CS settings,
Check BIOS settings for boot order,
And lastly have your BIOS rescan your HD or
Reset your BIOS to defaults.....

To enter the Bios (see your computer screen at power on, your manual, or manufacturer's web site) you probably have to press something like the DEL Key, or one of the F Keys at boot up time, but the actual Key varies from model to model. Many computers refer to this as "Entering Setup", Setup is just another term for the Bios.

Setting your Bios to any safe default settings may also fix this for you.
