|“Ignore the CPU/RAM bar”, what does that even mean? |
Here’s the BIG question: What were doing to it to make it
stop booting (ha ha, if anything)?
User/Service Manuals can usually be downloaded from the Mfgr’s & MOBO websites, might take a tad bit of effort
+ I'd open the machine and look at the motherboard 1st and look for bad capacitors.
+ Note & record any LED and power lights and beep codes when you are trying to start it. Also note if your fans (CPU, case and Power supply fans) are turning.
+ Try to get into the BIOS if you can, dig around in the menus to see if any hardware devices are missing or unconfigured.
+ Test Power supply, or try new replacement PSU.
+ Check the CMOS battery to see if it’s good (system should usually boot though with a bad battery).
+ Unplug from power cables (or pull out if applicable) all peripherals from the motherboard: HDDs, RAM, Video cards,
PCI cards etc.
+ Clean system from dust & debris, slots, fans, & especially from CPU heat sink & fan (if needed).
+ Attach a monitor, keyboard & mouse, then test boot. Note LED lights & beep codes (you should get a no RAM present beep code with no RAM in system).
+ Add in one component at a time starting w/ RAM, then test boot with each component you add.
Just another stupid saying...
