Compaq Presario 6370us.
I turn it on, after a few seconds, the fans begin to spin and stop within 3-4 seconds. Nothing else happens.
I put in a new power supply. No change. I cleaned it good (it was REALLY dirty). Thinking the compound on the heatsink might be degraded, I removed and re-did it. No change.
I disconnected everything. Right now, I have the PSU, CPU and motherboard only, but when I put in the power, the same thing happens. The fans don't run long enough to feel the air.
Can someone tell me what to try next? I am on the verge of ordering a new motherboard.
BTW, I have removed cmos and battery for short periods and overnight. I have changed out the battery. I have removed the ram.
Now, I'm just looking for a new direction. Thanks for any help.
