Previous PC Spec:
AMD 1600+ Athlon XP
2 x 256MB Twinmos PC2100
New PC Spec:
AMD 3100+ Sempron 64 Bit (Skt 754)
2 x 512 Corsair DDR400
ECS NForce3-A v1.0a Mobo
It has 2 HDD's, a Radeon 9600 and a 300W PSU.
After setting everything up (replacing the mobo in the case) it failed to even power up, this was later resolved to an unused mounting screw shorting the board out and was removed. After that everything was ok, I had a few problems enabling Gate A20 to fast mode so I could install windows but got past it in the end. I ended the night having formatted the harddrive and was ready to install windows today. The PSU comes with an isloator switch on the back, the onboard LAN was making a noise after I turned the PC off to I switched the isolator switch to off.
When I wake up this morning and flick the isolator switch to on the PC immediately powers up, but no post beep. This was common me for the past few weeks where I would need to turn the pc on and off a few times before it would run the POST. So apart from turning itself on without me pressing the power button I thought nothing of it until 20 minutes later when it still wouldn't run the POST. I always meant to switch the power supplies, which I did right afterwards. Same problem. After getting back from work tonight, I removed everything except the CPU, mobo and the power supply with no avail.
Considering I didn't do anything from turning it off at night to turning on this morning I really am stuck for a solution. Static discharge is a possiblity but I am always *very* careful when it comes to this. Also I am well aware the motherboard may be fried, though I refuse to believe it is.
Many thanks in advance.
