Just my two cents here. Problems like this are usually the power |
57 |
supply. Could it be the mobo, yes it could but the power supply is more |
58 |
likely, usually cheaper to replace and easier to. I had a friends puter |
59 |
that was acting weird, random reboots and such, it was the power |
60 |
supply. A bad power supply can cause all sorts of weird problems. |
61 |
|
62 |
If you can, unplug everything including the CD/DVD drive. No hard |
63 |
drives either. Just play with the BIOS. Basically, don't try to boot |
64 |
anything, just look at the BIOS itself. If it acts weird, start with |
65 |
the power supply. If you have to, go to a local place and pick up a |
66 |
cheap power supply. Put it in just long enough to see if that is the |
67 |
problem. If it works, then order you a real good power supply. Just |
68 |
keep the cheapy for testing purposes. If the cheapy power supply |
69 |
presents the same problem, then it could be the mobo. |

71 |
Random problems are hard to fix sometimes. You just have to swap things |
72 |
until you find the bad part. I would put the odds at 80% that it is the |
73 |
power supply tho. |
74 |
|
75 |
While at it, do you know what brand and the wattage of your power |
76 |
supply? It could be that someone on here as experience with that |
77 |
particular brand or even that exact model. |
