I'm having trouble getting my computer to boot up. Would appreciate any help. Is my motherboard fried?
Computer won't boot, won't go to POST. No beeps. Power button light does not light up. PSU fan, CPU fan, case fan all spin. Hard drives spin up.
I removed the passive heatsink on top of the north bridge, wiped off the old thermal compound with 70% isopropyl alcohol and a cotton pad, and reapplied new thermal compound (Artic Silver 5) on the north bridge, re-installed passive heatsink.
What I tried:
I've checked all the wires - nothing loose I tried removing the heatsink and booting without it - no difference I tried waiting several hours before booting again - still no beep, doesn't power up fully Resetting CMOS - nothing
Last summer I bought a Gateway DX4822-01 and everything ran perfectly until this summer when it started overheating. I did all the basics - clean the dust off the fans, re-appled thermal compound to the CPU, added a new case fan - but the damn thing would still shut itself off randomly. I was busy, so I kept the case open and used an external fan to blow at it while running and it run smoothly for hours with no problem. Today I had some free time so I decided to re-investigate the issue and discovered the north bridge running very hot whenever the computer was on. So I decided to clean and re-apply the thermal compound on the north bridge in an attempt to make it run cooler. Everything else was working fine before (as long as the external fan was blowing).
