Just got a Asus m4n68tm motherboard 250 processor 2gig ram to go with a half gig hd and a 450w psu. Assembled everything nicely and fired the thing up only to find - no video. Everything seems ok but just no picture. Tried 2 different screens but nothing. Any advice?

1 long, 2 short Failure in video system: a checksum error was encountered in video BIOS ROM, or a horizontal retrace failure has been encountered

You have a bad RAM, install just 1 module and try, is doesn't swap the memory module and try again.

Launching Google Chrome is no magic bullet it's actually just a lot of spyware...it would not make any difference in the load on the CPU

The only thing i can suggest is remove one of your RAM sticks and see if the machine will boot. I had this problem with mine and it turned out that one of my RAM slots was faulty and would not boot if both RAM slots had RAM in them.

hi,
I think One long beep that continue means RAM problem , Ram Can May be dead or faulty, check on other ram.

I hope that this has been very helpful for you

Your system might only be able to recognise 2gb of RAM. Tiger Direct has a RAM finder for almost every computer. Check it out to see if you have too much.

hi..for this mother board model asus K8U-X only same brand Processor u can oly use.Like if u use Sempron made by AMD only AMD Processor for that board.Memory support is DDR1 PC400 1gig up to 2gig...good luck and Have a Nice Day..

Get a 600 watt they are better and will handle all that you need the price from a 450 W to 600W is not much I run 7 dvd's a ATI Video capture card with a 64 bit AMD processors 1 80 gig Hd 2 Sata Drives 120 gig and sound blaster audio card and more and the 600 watt does fine The Corsair is ok Where to you think your going to get it at on line? or at a store? You can buy them at
tiger direct.com or Fry's.com The 600 watt ATI power supply will have 6 standard HD connecotors and I use three Y's for more and never had any problem with mine.

try using a bare system only means motherboard, psu, processor, ram then connect a speaker, does it make any sound ?
