Situation/Problem: If I shutdown the computer and leave it off for > 30 mins and power it back on again, the computer doesn't boot and nothing appears on the screen. After a few random turning off and on the computer it finally beeps and boots and everything is fine. I've tried the advice giving in the sticky;
Nothing on the screen with no beeps
1-Make sure the hs (heatsink) is installed properly, tight with thermal paste applied
2-Make sure the cpu fan is connected to the correct header on the motherboard
3-Clear the cmos by unplugging the computer removing the battery then move the clear cmos jumper from pins 1&2 to 2&3 for 10 minutes
4-Replace the battery and move the jumper back to pins 1&2
5-Verify all motherboard jumpers are set correctly
6-Verify all case connections are correct ( case switch ect.)
7-Verify the power supplies 20/24 pin and 4pin 12v are tightly seated to the motherboard
Even tried reseating the memory, removing and putting back the drives;
But it still doesn't work.
So I'm not sure what is the problem because it will only boot sometimes.
Here are the specs:
ASUS V3-M2A690G AMD Socket AM2 Barebones
AMD Athlon 64 X2 4600+ CPU
2GB DDR2 Dual Channel
500W Power supply
MSI NVIDIA GeForce 8400GS
SATA Western Digital 160GB HD
Any advice/help is appreciated! Thanks in advance!
