Cisco router HWIC card not working

I pulled out HWIC card from a Cisco 3845 router and inserted it back while the switch is powered ON. I didn’t realise this is not hot swappable while doing that. The router rebooted itself with bus error “System returned to ROM by bus error at PC 0x0, address 0x0”. After the router is rebooted I couldn’t see the HWIC ports coming up. They are showing as “Serial0/0/1 is down, line protocol is down”. Could some one help me how I can fix this?

Have you turned off the router since and done a "cold start"?
After that, do "show version", and see what interfaces are present. An example (from a 2800 router):

Cisco 2801 (revision 6.0) with 240640K/21504K bytes of memory.
Processor board XXXXXXXXX
2 FastEthernet interfaces
2 ISDN Basic Rate interfaces
2 ATM interfaces
1 Virtual Private Network (VPN) Module
1 DSP, 4 Voice resources
DRAM configuration is 64 bits wide with parity disabled.
191K bytes of NVRAM.
1982232K bytes of ATA CompactFlash (Read/Write)

Have you changed the IOS on this router since? Some versions of IOS don't recognise all new(ish) hardware like the HWICs. Which HWIC is it?

It should also appear in "show controllers". The output will be long, so you'll have to look through it.
