Hey,

Recently my computer has been doing alot of weird things, at first I thought it was the graphics card but then i reasearched into it and I found that the power supply might be the problem. Now having bought and installed a new powersupply that even has alot more "juice" then my old one, my problems still continue.

Basically there are a number of things that happens:

• Computer will randomly switch off/restart
• Screen will go into standby randomly as if the computer was off, (computer is not off).
• Screen will freeze and a (somtimes there will be a recurring noise)
• Screen will go into standby then come back on again, and then the point above will happen.

I think i may have a left a few out, but i cannot remember off the top of my head.

Just as a note,

The above are problems i come across ont he rare chance that i actually apss the boot up stage. I generally have to keep restarting my computer until it actually gets to windows as it freezes very frequently.

Also, this is possbly just me, but its seems, the longer i actually leave the computer the longer is stays "alive" when i come back to it. But this is probably not true.
It would be interesting to know what you guys think the problem could be and how I could fix it. Any suggestions are very welcome.

Thanks in advance,

Hi and welcome to D-A-L

check everything is seated properly (RAM, graphics card , sound card and any other cards) and all connections are good.

Everything seems to be okay.

Faulty RAM or a faulty motherboard could cause all of those issues. A faulty motherboard is a real hassle to test as it basically means rebuilding the PC. However, testing faulty RAM is relatively straightforward. If you have more than one RAM module inside the PC, remove the extra modules leaving just one fitted. The PC will probably be slower but see if it is more reliable. If it is not, remove the RAM module and fit the other one back in. Again, see if it now works reliably. If either of these steps gives you a slow but stable PC, then the RAM that you removed is faulty and should be replaced.

If you only have one RAM module, you would unfortunately have to buy another or borrow the same type of RAM from someone so that you can carry out the above tests.
