Acer Aspire 5930G Infinite boot loop! HELP! :(

Hi guys.

I have a major problem with my Acer Aspire 5930G. It all started last week when the machine started restarting just after the 'Starting Windows' scene goes. Before this, once when the laptop booted fine, I noticed that the date and time had reset to 2008. So believing its a CMOS issue, I disassembled the entire laptop, changed the CMOS battery, cleaned the cooling system, put new thermal paste for the graphics card/processor, reseated the RAM, even switched them, replaced the HDD but no avail. The machine just keeps restarting on infinite loop. I have Linux Mint on another partition, but it does the same, just after those tiny blobs of loading goes, the system restarts. Even if the battery is inserted or on direct line plugging, same issue.

I can't even use a bootable DVD now (tried with a Windows 7 disk, but still same issue), I managed to get into SAFE MODE once, tried system restore and ended up corrupting the startup that the only option is to use a system disk cuz it says some file failed to load. Oh boy!

Altogether, I am in a mess. I have lots of work halfway done in the machine (though I can connect the harddisk via an adapter and use it elsewhere), but I have expensive software (single licenses and updates) in it.

It would be great if you guys could help me figure out a solution here. The last option I am thinking is whether a BIOS flashing/upgrade would do.

What do you suggest?

 

BIOS flashing won't help.

It's definitely a hardware issue though. Can you test different RAM sticks? I doubt that's the problem but if you tested that we could rule it out.
It might be a mobo issue though. If it's not RAM, HDD, or power issue- the only obvious one is mobo failure.
