Help on new build?

[ILM]

My PC had frozen a few times randomly, whilst watching Youtube videos, surfing the net, closing other flash videos.

It's recently had a new motherboard, RAM and CPU installed (3-4 weeks ago) and these BSOD events (freeze/reboot) have only occurred after that.

OS Version: Microsoft Windows 7 Enterprise, 32 bit
Processor: AMD Athlon(tm) II X2 250 Processor, x64 Family 16 Model 6 Stepping 2
Processor Count: 2
RAM: Crucial 2GB DDR3 1333MHz/PC3-10600 Memory CL9 1.5V
Graphics Card: ATI Radeon HD 4250, 384 Mb
Motherboard: ASUSTeK Computer INC., M4A88T-V EVO/USB3, Rev X.0x, MT7013040701135
Harddrive: Seagate 160 GB SATA (ST3160023AS)
DVD Drive: Lite-ON DVDRW SOHW 1633S ATA Device

Have I missed a glaringly obvious issue?

I am willing to upgrade the Hard Drive and the DVD Drive if people can recommend a cheap alternative, less than £50 in total please.

I will also change the motherboard if a more compatible one is found, I can return it as faulty within the next month, however I would like to get this all sorted by Monday.

Finally the RAM, I am also willing to change it but it does not seem to be at fault after running several passes of MemTest without fail.

did you format the harddrive, and reinstall teh OS, that could be playing a major part.

I have reformatted and reinstalled windows, the only issue I can think of is the on board video card or the motherboard itself, that's why I asking about a possible replacement?
