Need 2 replace MB asap

hi guys, I need your help

I've been getting the blue screen and the self-reboots on my computer lately, I have reason to believe it's cus of the MSI motherboard. I replaced the motherboard in Jan 09 for the exact same problem. I had no idea that it's a cheapo when I bought it.

This one here: http://www.newegg.com/Product/Prod [...] MSI%20750i

I'm looking for a quality replacement that fits the chipset asap cus I use that computer for day-to-day business. I was told to get either Asus or EVGA, but don't know which one to get.

My computer:
Apevia X-cruiser Case http://www.apevia.com/productsInfo [...] CRUISER-AL
MSI P7N SLI-FI LGA 775 NVIDIA nForce 750i SLI ATX Intel
Intel Core2Duo E8400 3.0ghz 1333FSB 6mb L2 cache 64bit
NVIDA GeForce 9800 GTX 512mb 16x PCI Express
4GM PC6400 DDR2/800 Dual Channel Memory
Windows XP Home Service Pack 3

Please help! I'd like to fix this fast so I can forget about it

1. Cleared CMOS?

2. What PSU?

As for a good P45 board, consider the P45-UD3L. It's a good quality board. I'm assuming you won't SLI down the road.

Dunno what cmos is, I use the Apevia Java 500w power supply

I think i"m gonna stick with sli though
