k7VM2 Won't Boot

[bountybar]

I have had an Asrock k7VM2 for around 6 months. All was OK until last week. It will not boot. The CPU fan spins for a couple of seconds, then turns off. I try to start it again with the switch but then nothing at all happens, not even for a few seconds. If I disconnect the power supply from the mains for a few minutes, then re-connect, it usually starts OK, but not always. It sometimes takes two or three attempts before starting up. When I say it will not boot, it does not complete the POST before it turns off.
The CPU is a Athlon 1800, with 256 MB DDR RAM.

Help!

you said you almost tore out the cable on your monitor...

could it be you damaged the connection between your gfx and your mobo? That would explain you not getting any signal to your monitor...

look carefully at the agp socket, see if u can see any damage, and also use a different gfx (if u have one) and see if that works...

Its not the monitor or the power supply like most people have posted. There seems to be a problem with the RAM and the AMD processors. Can't put my finger on it but it has happened to me with 3 different motherboards all with AMD processors 2 athlons and one duron. Everything you have described in your problem statement happened for each system. I have yet to find a solution for this problem. Would anyone know how we could report this as an issue to AMD. Is it a problem with the manufacurer of the RAM? Are the Athlon processors picky about which piece of memory its used with? Does AMD have a listing of compatible memory for their processor? Any suggestion and push in the right direction will help. Thanks

Hi;
I had this exact problem within two weeks of putting my computer together. I had no floppy drive so I stuck an old one in I'd had banging around for a year or two. My computer would only power up for about a second and then shut down. Removal of the floppy drive meant a perfect boot. Went out and bought a new floppy drive and all was solved. I stuck the old floppy drive in an old P2 I had and almost fried it. My guess is a bit of bad hardware.

I think I've finally sorted it. For the benefit of anyone else with the same problem, I reset the jumper PS2_USB_PWR1 to pins 1 & 2 (+5v). Factory setting is 2 & 3 (+5vsb). The jumper is positioned near the PS2 mouse socket. It is something to do with PSU voltage stability. Whether it's a fault on the MB or something else, I don't know, but it's OK now, and that's what matters.
