I installed windows 7 several months ago and everything has been running fine. However, about a month or so ago, sometimes when I turned the computer on, it would not detect the network card. Normally I would just restart it repeatedly until it did, and when it did find it it ran normally. Recently, it has been taking longer and longer to get it to detect it, and, increasingly, it would just freeze at the first black screen.
Yesterday, my friend (who knows substantially more about computers than I do) came around to clean out the inside of the computer (it was incredibly dusty). Afterwards, it worked just like before, and wouldn't detect the wireless card. However, after several reboots, a new error appeared:
CMOS checksum error - defaults loaded
Warning! now system is in safe mode.
Please re-setting CPU or Memory Frequency in the cmos setup
When I restarted it this time, the computer beeped several times, rather than the usual one beep, and nothing came up. Now, the computer wont turn on at all. Anyone know why/what I can do to get it working again? I already tried asking my friend, and he was not sure what was wrong either.
I have a XFX nForce 630i motherboard (http://www.xfxforce.com/en-us/products/motherboards/6series/630.aspx), if that is relevant.
Thanks in advance
