What is my problem?

Specs: Gateway MX7118, 787MHz/448MB
I have problems with this Gateway MX7118 laptop. When I first got it, the power "light"would turn on for 10 seconds...shut off for 3 seconds....light up again for 10 seconds...then just shut down. No screen reaction. I removed everything ,one by one, except the CPU, memory from the motherboard. Best Buy said it was motherboard, so I spent $175 for a new one, put it in and it worked for about an hour,and guess what...same problem, lights up for 2 cycles of ten seconds as above. So, I took it all apart, put old motherboard back in and it worked for about an hour, got BSOD and I am right back to square one (10 sec. light up). I believe the MB is good. I question if memory card can do this....or maybe my CPU fizzled out?? One other thing I noticed from start menu and computer properties it said 2.20 GHz proccesor and from control panel & system it said 787 MHz for proccesor speeds!!?? That is weird!!I could really use some help on this...I would be grateful for any assistance. Thank You

Run memtest for an idea on memory quality.

Never ever try to fix a laptop. Throw them away or recycle them. Just too hard to fix unless you have line support.

Never trust the idiots at Best Buy.

Why didn't you take back the thing from day one?

Can't say how many FRU's are in the laptop. Really anyone could cause it. Modern laptops are very complex in how they use power. A signal from almost any part could cause a problem.

BSOD's can be caused by any part really or any firmware or software loaded. Since we don't have line tests we can't compare this to a similar batch from the same parts level. Parts in motherboards change slightly each day. Thousands of variables.

Why did it take me over a year to phone in a problem to ATT?

Why are you investing any money in an old machine? If you had problems since day one, why didn't you return it immediately? And why wasn't the board covered under warranty? My guess is you voided the warranty as soon as you opened the case. If you get the problem sorted out, get more RAM, 448MB is pathetic these days. Do NOT install Win7 on that machine.

There's nothing wrong with your CPU speed, that's just Cool'n'Quiet doing it's job. If the CPU ran at full speed at all times, the battery would last about 30 min. Cool'n'Quiet varies the CPU settings based on load - light load 787MHz, full load 2.2GHz - that way you can get 2-3 hrs out of a charge.


For the most part, CPUs either work or they don't. The fact that the system works sometimes means the CPU is probably OK. However, it may be overheating. Did you apply thermal paste between the CPU & heatsink? Just a tiny dab in the center of the CPU?

Ok I understand what you are saying. Got unit free and like working on them (kinda). You said DO NOT put windows 7 on that machine. After I had new motherboard installed windows 7 install screen came up and I DID install it. Is this my problem?.. and if so... do I need to format the drive and reinstall or am I done for good? Thank You

You should have clarified that this was a used system in the OP.

You need a minimum of 1GB RAM for Win7 32-bit. The minimum for the 64-bit version is 2GB. And remember, that's the MINIMUM. It doesn't necessarily mean the system will perform well with that amount. 448MB is barely enough for XP.

I don't know that Win7 is the problem or not, but personally, I wouldn't have even considered installing it on that system without 1st upgrading the RAM to 2GB. I suggest you format the HDD & install XP.

I installed Windows Internet Explorer 7" not Windows 7. I believe one is a browser program the othger an operating program. Anyway, I pulled the battery on the MB for a day, reassembled and now it powers up "all" the time, battery or ac cord. And my screen just flicks once but doesn't work. Would this be possible after a BIOS reset to default. I have no manual for this MB. I also have no reinstall disk for XP Media Cenetr Addition. I wonder if the BIOS reset has put unit into "never" shut down by factory defaul and I lost my drivers for the screen??? Help!!

You're obviously out of your league. Take it to someone who knows what they're doing.
