Computer wont boot, 1 Long 3 Short beeps

[Jono310]

Hi all

Recently my computer shutdown on me and BSODs when windows is starting

When the computer initially starts there is 1 long beep followed by 3 short beeps which when looking online means there is an "AGP error". I was just wondering how i can fix this and what this problem is caused by?

I have tried it with different RAM and get the same problem. Also I removed the GPU and I still get the same problem but without the beeps and also the first time i removed by GPU it mentioned the BIOS was corrupt and had to Backup.

Could this mean i have to replace my motherboard?

Also on the blue screen it is the 7b error if this helps

Thanks

The beep errors have different meanings depending on the BIOS type.  Since you haven't told us what board you have I'm not going to guess.

One can be graphics related, the other memory.

BIOS corruption and a Inaccessible Boot Device error 0x0000007b

Can you please provide your full system specs, board, rev #, BIOS and version, installed devices, disk configuration, operate mode of the disk controller, etc.  The more information your provide, the better.

Did the PC ever work, for how long.  Have you recently changed anything?  What happened?

You have multiple, seemingly unrelated problems.  Its strange how they all appeared at once.
