My computer doesn't boot.

[SeedOfHate]

My computer won't boot up, it doesn't even do the little beep anymore. The fans are all running, the HDD and Power led are both lit up, the green power light on my motherboard is lit also. The green power led is always lit, when the computer is off, its a bit dimmer and when its on, its brighter. I tried reseating my video card, reset the Cmos by taking off the lithium battery on my motherboard, switching rams, taking a stick of ram out one at the time, reseating the heatsink and nothing worked. Here are my specs if it can help. Please answer ASAP. Thank you.

Specs :
Asus a7v8x-x mobo
AMD Athlon XP 2000+
Ati All In Wonder 9800 pro
pc3200 1GB generic ram

Hello and welcome to Techspot!

So you system was working before and suddenly has stopped? You have made no changes recently?

It sounds like your troubleshooting has been pretty thorough. However, as you are not getting the beep, the first thing I'd suspect is your ram.

Do you have some other ram you can test in your system?

Other possibilities would be a dying psu, or motherboard. Do you see any swollen or leaking capacitors on your board?
